Description
Technical field
The present invention relates to a kind of special-purpose fertilizer, particularly a kind of special fertilizer for peanut.
Background technology
Peanut is the important oil crops of China, and planting range is very wide, and to the north of cold, coastal from the western Xinjiang to the east all have a plantation from the south of sweltering heat.Peanut is of many uses, except that making oil plant, at food, chemical industry, pharmaceutically many purposes are arranged also.Peanut stem leaf is nutritious, is good feed, and Pericarppium arachidis hypogaeae is an industrial raw material.The plantation peanut, owing to be leguminous plants, root nodule can fixed nitrogen, can increase soil fertility.
The peanut growth and development stage experiences seed germination seeding stage, seedling phase, blooms pin phase, fruiting period and ripening stage down.Peanut is a leguminous plants, and the airborne free nitrogen of peanut rhizobium energy fixing soil is for self nitrogen nutrition.Peanut absorbs nutrition except that root system, and blade, fruit pin, young fruit also have the ability of direct absorption mineral nutrition.
Peanut absorbs the organ of nutrition except that root system, and blade, fruit pin, young fruit also have the ability of direct absorption nutrition.
The fertile characteristics of the suction of root: root system is the major organs that peanut absorbs mineral nutrition, and the nutritive substance majority that peanut needs is to rerun to be assigned in other organs after absorbing by root system to go.Its order that absorbs running is: root system at first runs in the cauline leaf and goes after absorbing nutritive substance, and then is transported in fruit pin, young fruit and the pod and goes.The nutrient priority of supply side shoot that same column absorbs to lateral root.
The suction fertilizer and the operation characteristics of leaf: peanut leaf also has the ability of direct absorption nutritive substance and can transport other positions to.Give birth to early stage, the phosphorus element that stem and side shoot blade absorb, priority of supply self needs, and along with the progress of breeding time, the phosphorus element that the stem blade absorbs has 79.5% to run to other positions in the fruit phase of satisfying.
The fertile characteristics of the suction of fruit pin, young fruit: peanut pin, young fruit also have the ability of direct absorption soil nutritive substance, but this absorption fades away with the pod growth.The fruit pin of peanut and young fruit can directly absorb nitrogen nutrition, and when especially the topsoil gong nitrogen level was low, peanut increased by the quantity that the fruit pin absorbs nitrogen in the solid layer.
Peanut to the absorbing rule of main nutrient elements is:
Nitrogen: mainly be absorbed with nitric nitrogen and ammonium nitrogen, sources of nitrogen has soil to supply nitrogen and root nodule bacterium fixed nitrogen for nitrogen, fertilizer.Peanut is 41.8%-50.4% to the nitrogen equivalent absorption rate in the chemical nitrogen fertilizer, and absorption rate and amount of nitrogen are extremely significantly negative correlation.Under the condition that medium fertility soil does not apply fertilizer, sources of nitrogen in the peanut plant body, root nodule bacterium are 79% for the nitrogen rate, execute in the purity nitrogen 2.5-15 kilogram scope for every mu, root nodule bacterium are 17%-71% for the nitrogen rate, and fertilizer is for nitrogen 6%-40%, and soil is 22%-57% for the nitrogen rate.Nitrogen that peanut absorbs is at the partition rate of each organ, and different growth stage is inequality, seedling and blooming the following pin phase, and nitrogen mainly is used in leaf portion, and the dry-matter nitrogen content is respectively 3.94% and 3.86%; Bearing pods turns to fruit pin and young fruit by leaf portion, and the content of nitrogen is 3.15%-3.82% in its dry-matter, and the full fruit phase concentrates on pod, and nitrogen content is 3.53%-3.88% in its dry-matter.As seen each period the nitrogen amount being absorbed is isostatic basically, and fertilizer specially for peanut must possess the characteristic of balanced liberating nitrogen, could satisfy the grow needs in each stage of peanut.
Phosphorus: peanut is only second to nitrogen, potassium, calcium to the requirement of phosphorus, occupies the 4th.Every production double centner peanut pod needs to absorb plain 1 kilogram of phosphorus.The absorption rate that peanut is executed the phosphorus fertilizer to this season is lower, is 15%-25%.This is because phosphate fertilizer carries out multiple reaction after being manured into soil, and in the acid soil, easily the phosphoric acid salt as iron or molybdenum is fixed again; In alkaline soils, then easily be fixed as tricalcium phosphate.At pH value is 6.5 o'clock, and the plain utilization ratio of phosphorus is the highest, when the fertilizer specially for peanut formulating of recipe, must consider this point.
Peanut is that two is few in the absorption and distribution of whole growing to the phosphorus element, and the centre is many.When prescription is produced fertilizer specially for peanut, must consider phosphate fertilizer variety and water-soluble phosphorus content, to guarantee each phase demand.
Peanut plant can absorb a large amount of potassium, and every production double centner peanut need absorb plain 2 kilograms of potassium.Peanut plant breeding time potassium content can reach 4%, and when containing potassium 2.15%, it is best that organ of multiplication is grown, and potassium deficiency symptom is appearring in potassium content below 0.75%, and potassium is easy to move in plant.Peanut is maximum with the following pin phase of blooming to the absorption of potassium, and fruiting period takes second place, and the full fruit phase is less.The stem's dry-matter of following pin phase of blooming contains potassium 1.58%, and fruiting period is 1.28-2.63%, and the full fruit phase is 1.28-2.56%.
Calcium: peanut is big to the requirement of calcium, is only second to nitrogen, potassium, occupies the 3rd.With other crop ratios, be about soybeans doubly, 3 times of corn, 5 times of paddy rice, 7 times of wheat with output.The flowability of calcium in peanut plant is poor, has only the fruit calcium that pin and young fruit absorbed to accumulate in a large number in pod, and the calcium at other positions has only a small amount of moving.The peanut different growing is to the absorption of calcium, and is maximum with fruiting period, and the following pin phase of blooming takes second place, and seedling phase and full fruit phase are less.In breathing out the special fertilizer formula design, must guarantee the plain supply of competent calcium, could satisfy the peanut plant needs.
Peanut is to the requirement of main nutrient elements, and its trend is to increase along with biological yield.According to surveying and determination, every mu of total organism of colony that produces 200-300 kilogram pod needs nitrogen 11.3-13.4 kilogram, the plain 2-3.7 kilogram of phosphorus, plain 11.9 kilograms of potassium, the plain 3.6-8.7 kilogram of calcium.Early, middle and late ripe kind requirement has less difference.Provide the fertilizer of these nutrient substances that farm manure and chemical fertilizer are arranged.Farm manure such as barnyard manure, people's muck, compost, vegetation fertilizer though the characteristics that nutrient is complete, fertilizer efficiency slow, the effect phase is long are arranged, only should be made base manure and seed manure and use.It is more effective generally to use chemical fertilizer.Chemical fertilizer is generally used urea, carbon ammonium, ammonium nitrate, sulphur ammonium, general calcium, coarse whiting, fused(calcium magnesium)phosphate, vitriolate of tartar, Repone K etc., but these fertilizer separately use and take a lot of work, require great effort, and uses inaccurately, and the nutrient weighing apparatus that has much difficulty in healing can only lean on the manpower estimation to apply in the soil.Therefore, in time grow and inhale fertile rule development research and go out that nutrient is complete, the peanut of reasonable ratio is compound fertilizer dedicated, just solved this problem well according to nutritive element demand and peanut.
Yet, understand few by peanut cultivation family, China rural area to the Basic of Biology of peanut cultivation, the fertile rule of growth characteristic, nutritive property, suction to growthdevelopmental stage such as seed germination seeding stage, the seedling phase of peanut, the following pin phase of blooming, fruiting period, full fruit ripening stage etc. is understood not saturating, plantation peanut and apply fertilizer and have bigger blindness and cause per unit area yield not high is only about the 130-150 kilogram.Particularly be subjected to the influence of traditional fertilization method, fertilising kind, nutrition were disposed extremely unreasonable when peanut was planted by farmers', ignore nitrogen, phosphorus, potassium, calcium, magnesium, sulphur and trace element reasonably combined, cause soil nutrient seriously unbalance, cause grow each nutrition supply of peanut bad in period, blooming, pin quantity is few down, setting percentage is low, the ghost rate increases, and thousand seed weight descends, and not only output is difficult to improve, the equal variation of peanut meat matter and mouthfeel, oil length also reduces.Though there is the peanut compound fertilizer special to sell on the market, it is few to inhale the fertilizer variety of fertile rule according to differently region soil and peanut targetedly, does not meet the requirement of balance fertilizing, rational application of fertilizers, thereby is not suitable for the peanut cultivation needs.
Summary of the invention
The objective of the invention is to provide a kind of special fertilizer for peanut.From the research peanut nutritive property in each of growing in period, grasp it and inhale fertile rule, and according to region soil fertility difference differently, a kind of nitrogen of balanced arrangement, phosphorus, potassium, calcium, magnesium, sulphur and the rational composite fertilizer of micro-ratio, solving in the peanut cultivation process is problem.In the peanut cultivation practice, obtain gratifying effect, become a kind of the special-purpose fertile of peanut cultivation of really satisfying.
Under the condition that general per mu yield peanut is 200 kilograms, every production double centner pod needs absorbed nitrogen (N) 4.9-6.4 kilogram, phosphorus (P
2O
5) the 0.9-1.1 kilogram, potassium (K
2O) 1.9-3.4 kilogram.In addition, also have calcium, magnesium, sulphur and the trace element of some amount as iron, boron, molybdenum, zinc etc.The function of the main nutrient elements that peanut is required is as follows:
Nitrogen: nitrogen participates in the synthetic of itrogenous organic substance matter such as protein, chlorophyll, phosphatide, and the substance metabolism process in all physiological functions, to promote the peanut tiller to come into leaves and to yield positive results.Nitrogen mainly is present in kind of the Renhe blade with protein, the organic state of chlorophyll, and the nitrogen content in pod and the blade accounts for the 56%-76% and the 12%-13% of complete stool total nitrogen respectively.Every production double centner pod need to absorb 5 kilograms of pure oxygens, be equivalent amount cereal crop 1.3-1.4 doubly.When the nitrogen supply is suitable, the peanut riotous growth, leaf area increases fast, and the leaf look green, and photosynthesis is strong, and pod is full.If nitrogen stress, then peanut plant dysplasia, straw are short, and it is few to bloom, and yields poorly; If nitrogen is too much, plant excessive growth lodging and late-maturing low yield then can appear again.
Phosphorus: the phosphorus element is absorbed by peanut with the phosphoric acid attitude usually, participate in the synthetic of organo phosphorous compounds, mainly be present in the peanut kind benevolence with organic states such as phosphatide, nucleoprotein, also there is part phosphoric acid to be present in mineralized in the organs such as cauline leaf, participate in the carbon nitrogen metabolism process of plant body, to photosyntheticly carry out, the conversion of proteinic formation and oil content plays an important role.Phosphorus can promote seed germination, and the growth of root and root nodule, can also strengthen the ability of the low temperature resistant drought resisting of seedling, and the contact pin that can promote to bloom, many results and raising plumpness more.Phosphorus element content in pod is a lot, can account for the 62%-79% of complete stool total phosphorus content.The synthetic of carbohydrate is suppressed with decomposition, the nitrogen metabolism imbalance, the protein composition is destroyed, and plant strain growth is bad, and blade is blue-greenish colour, upsweeps, and because the accumulation of anthocyanidin, lower blade and basal part of stem often take on a red color or red line are arranged.Peanut seedling stage under the situation of cold weather, serious phosphate deficiency shape often occurs, but the same day, cyclostrophic was warm, and after the root system expansion, the phosphate deficiency shape generally disappears.
Potassium: the potassium element enters in the peanut plant body with ionic condition usually, though be not the integral part of organic substance, it participates in various physiological metabolism activities.Potassium can promote photosynthesis, and when potassium was sufficient, plant strain growth was fast, and the activity of enzyme is strong, thereby has improved rate of photosynthisis.Potassium helps protein synthesis, can promote nodule nitrogen fixation, and the activation amylosynthease promotes carbohydrate metabolism, makes synthetic disaccharide of monose and starch, accelerates the running of assimilation product to pod.Potassium can strengthen the regulating effect of cell to envrionment conditions, improves drought resisting, low temperature resistant, the lodging tolerance of peanut, and the harm that alleviates peanut sclerotium rolfsii, rust, leaf spot.The peanut potassium deficiency, blade is deep green, leaf margin brown deeply worried, macula lutea is arranged, to the imbalance of last volume, carbon nitrogen metabolism, photosynthetic productivity descends.
Calcium: calcium is the peanut necessary one of the chief elements that grows.Calcium is the integral part of calcium pectinate, is cell glue is moulded together and to promote the necessary material of cell fission.Calcium has good effect to the conversion and the nitrogen metabolism of carbohydrate, and calcium helps the absorption of peanut to nitric nitrogen when sufficient; During calcium deficiency, peanut can only utilize ammonium nitrogen.Calcium can be regulated the physiological equilibrium of external agency, eliminates the murder by poisoning that some crosses polyion such as ammonium ion, hydrogen ion, aluminum ion, sodium ion etc.During the peanut calcium deficiency, the plumule blackening of seed, pod is grown and to be gone down, during serious calcium deficiency, the plant blackening, petiole comes off, withers, top death, the root organ can not form, and root system is undeveloped, and the bubble fruit is many, and Mi Ziren is not plump little, and single a kind of fruit, such as apple, pear, etc. is many.
Magnesium: magnesium is chlorophyllous composition, and participates in the synthetic of plurality of enzymes.Magnesium helps carbohydrate metabolism and metabolism of fat, and rich the lacking of magnesium is related to peanut kernel oleaginousness height.Magnesium can also promote ascorbic synthetic.Magnesium deficiency not only can influence photosynthesis, also can make peanut meat matter descend the mouthfeel variation.
Sulphur: peanut belongs to happiness sulphur crop, and sulphur is amino acid whose compositions such as halfcystine, Gelucystine, nitrogen propylhomoserin, is the necessary element of protein synthesis.Sulphur has certain influence to chlorophyllous synthesizing, and during a lack of sulfur, chlorophyll content descends in the blade, leaf look thin out Huang.Sulphur can also promote root nodule to form, and strengthens the anti-septic ability of carpopodium, makes peanut be difficult for shedding and decayed fruit.
The function of trace element
When many manufacturer production peanut compounds are fertile, often ignored effect of trace elements, trace element adds improper or does not add, and is unfavorable for that all peanut grows.
Boron: the metabolism of involved in plant growth hormone and phenolate thing, can stimulate the peanut inflorescence to sprout and pollen tube growth, help fertilization.Boron deficiency influences the formation of pod and seed benevolence, influences the growth of the tip of a root and stem apex.Under the boron deficiency condition, cultivate peanut, the eclipsed hollow seed benevolence of a large amount of leaf inner face depressions can occur.During boron deficiency, peanut unfolded lobus cardiacus vein is of light color, the blade tip flavescence, and Lao Ye is a bit darkish in color, and branch is many, is the shape of growing thickly, and plant is short and small thin and weak, blooms seldom, stops growing, and the plant coring is few, and is easily downright bad.
Molybdenum: molybdenum is the integral part of nitrate reductase and nitrogenase, participates in comprising the oxidation-reduction reaction of nitrogen, promotes the nitrogen fixation of root nodule bacterium.Molybdenum can also improve and improve the absorption of peanut to the phosphorus element, and the toxic action to peanut such as the metal ion of eliminating excessive iron, manganese, copper is arranged.In the soil effectively molybdenum to be lower than 0.15 mg/kg be promptly to manifest the molybdenum symptom of falling vacant.Peanut lacks molybdenum and shows that with the nitrogen stress symptom the short and small root system of plant is undeveloped, the vein chlorosis, and the Lao Ye thickening is wax yellow.
Iron: in chlorophyllous biosynthetic process, need ferruginous enzyme to carry out catalysis.Iron deficiency, chlorosis appears in peanut, and the leaf look yellowish, even become white.Iron is the moiety of enzymes such as Terminal oxidase, catalase, peroxidase, thereby respiration that can the catalysis peanut.
Iron ion is easily fixing in peanut plant, and is mobile little, can not transform to young leaves from Lao Ye.During iron deficiency, the tender leaf chlorosis, it is green that Lao Ye still keeps.Iron deficiency not generally speaking, but in the high alkaline soil of pH value easy iron deficiency.
Zinc can promote the g and D of peanut, changes the infiltration to film of potassium and enzyme, promotes peanut absorbing nitrogen, potassium, iron.When zinc is not enough, the peanut leaf chlorosis.Scarce zinc also can reduce the biochemical quality of peanut oil.
The objective of the invention is to realize in the following way: according to above analysis, in conjunction with different regions peanut nutrient uptake feature, fertilizer specially for peanut prescription scheme is: in south China, North China, region, Central Plains, nitrogen, phosphorus, 1: 1.5: 2 weight percent of potassium ammonium are mixed, and it is more reasonable to allocate trace elements such as molybdenum, boron into, and generating total nutrient is the special-purpose fertile of 30%-36% nutrient.In basin, the middle and lower reach of Yangtze River and Lake Dongting area, because of the soil fertility situation is different from south China, North China, area, Central Plains, belong to rich phosphorus and contain the poor nitrogen geology of potassium, nitrogen content is higher relatively, through further thinking, nitrogen, phosphorus, potassium weight percent be 1: 0.6: 0.9 for suitable, and allocate in an amount of calcium, magnesium, sulphur, boron, the molybdenum etc. micro-, developing special-purpose fertile kind has for geographic fertilizer specially for peanut to the north of the Changjiang river, the total nutrient scope is 30%-36%, and the formulation weight percentage is N: P: K=6-8: 10-12: 14-16; For the fertilizer specially for peanut of areas to the south, the Changjiang river, the total nutrient scope is 25-30%, and the formulation weight percentage is N: P: K=10-12: 6-7: 9-10.
Adopt the prepared fertilizer specially for peanut of the present invention, to the north of the Changjiang river, since the areas to the south uses, because of the equilibrium of nutrient proportioning, nutrition supply rationally, the trace element collocation is appropriate, peanut cultivation has been obtained satisfied effect, and average per unit area yield has improved about 30-40%, and thousand seed weight increases about 10%, the peanut oleaginousness improves 6-8%, and peanut growth and development stage morbidity is few, and pod color homogeneous, attractive in appearance, pulp quality and mouthfeel become excellent, are subjected to the consistent favorable comment at peanut cultivation family.
Embodiment
Embodiment 1
For area to the north of the Changjiang river, the total nutrient scope is 30%-36%, the formulation weight percentage is N: P: K=6-8: 10-12: 14-16, soil mostly is alkalescence to the north of the Changjiang river, pH value is generally greater than 8, so fertilizer specially for peanut need be acid, and pH value is controlled at 5.0-6.0 and is advisable, realize that by adjusting proportioning raw materials the production formula design is as follows:
Urea: 40-80 kilogram sulphur ammonium: 50-100 kilogram
Repone K: 130-150 kilogram vitriolate of tartar: 50-70 kilogram
Calcium superphosphate: 200-300 kilogram monoammonium phosphate: 80-120 kilogram
Ammonium nitrate: No. 1,40-50 kilogram filling agent special: 30-60 kilogram
Boron fertilizer: 10 kilograms of molydbenum fertilizers: 10 kilograms
Zinc fertilizer: 20 kilograms
Embodiment 2
For the areas to the south, the Changjiang river, the total nutrient scope is 25-30%, the formulation weight percentage is N: P: K=10-12: 6-7: 9-10, it is acid that areas to the south, the Changjiang river soil is more, general pH value is less than 5.5, the fertilizer specially for peanut pH value is controlled to be 8.0-9.0 for suitable, also must realize by adjusting proportioning raw materials.The production formula design is as follows:
Urea: 80-120 kilogram sulphur ammonium: 50-100 kilogram
Repone K: 80-100 kilogram vitriolate of tartar: 30-50 kilogram
Calcium superphosphate: 200-300 kilogram monoammonium phosphate: 50-80 kilogram
Ammonium nitrate: No. 1,40-50 kilogram filling agent special: 60-100 kilogram
Boron fertilizer: 10 kilograms of molydbenum fertilizers: 10 kilograms
Zinc fertilizer: 20 kilograms
Because peanut is detested the chlorine crop for happiness sulphur, chlorion can influence too much that peanut grows and the pulp quality, ammonium chloride can obviously suppress root nodule bacterium fixed nitrogen simultaneously, therefore unsuitable adapted ammonium chloride and Qinghai Repone K, import Repone K and vitriolate of tartar ratio should not surpass 1: 1.5, otherwise chlorion easily exceeds standard.
It is balanced that peanut is inhaled fertile each period, rational application of fertilizers must guarantee each phase needs, instant and long-time slowly-releasing all is unfavorable for the peanut nutrition supply, consider and mostly be the nonirrigated farmland to the north of the Changjiang river, rainfall amount is few, slow-release period should not surpass 20 days in the fertilizer specially for peanut soakage water, otherwise rainfall after a little while in the fertilizer nutrient can not discharge, can not satisfy the peanut growth needs; Amount of rainfall abundance on the south the Changjiang river, water conservancy irrigation is convenient, and certain slow-release period must be arranged, and the sustained-release dissolution phase is no less than 35 days in the fertilizer specially for peanut soakage water, otherwise dissolves too fastly, and plant recovery of nutrient is low, and the peanut growth later stage can fertilizer deficiency and influences output.In filling agent special configuration and processing parameter control, reached above requirement.
Little fertile use wants suitably to allocate into too much and can work the mischief, and allocates into then inoperative very little.
