Description
Technical field
The present invention relates to a kind of special-purpose fertilizer, particularly relate to a kind of dedicated fertilizer for soybean.
Background technology
Soybean belongs to pulse family annual herb plant.According to the power of photosensitivity between kind and temperature sensibility, and different cropping system and sowing time, can be divided into early soybean, summer soybean, autumn soybean and the winter 4 types of soybean.Soybean is important grain and oil dual-purpose crop, is renown far and wide in the world well with its oil content height, quality.Contain protein 42% in the soybean kernel, fat 20%, carbohydrate 30%～33%.Her protein content is higher 2～4 times than grains such as wheat, corn, rice, and contains the amino acid of 8 kinds of needed by human, and rich vitamin A, vitamins D, is of high nutritive value, and " plain meat " laudatory title is arranged.Legume crop is commonplace in China's plantation, and north and south all can be planted, and is especially more with the plantation of northeast ground band.No matter it can both grow on the ground at rich soil and poor soil, and in the wasteland of some new reclamation of wastelands, beans is pioneer crop often.The plantation legume crop not only can obtain economic benefit, but also can play the effect of culture fertility.The main legume crop of China's plantation at present has soybean, Semen Ormosiae Hosiei, mung bean, broad bean, pea etc.The root of legume crop can both produce root nodule bacterium, and root nodule bacterium can provide 30～50% nitrogen nutrition for legume crop, and all the other 70～50% need obtain from soil.China's the Northeast's manufacturing soybean has accumulated rich experience, as one of content of precision agriculture, has progressively realized scientific management, has applied fertilizers scientifically, and soybean yields and quality have obtained improving constantly.Yet since the nineties, soybean is very pessimistic in areas to the south, the Changjiang river plantation situation, and cultivated area reduces year by year, is not that the peasant does not want to plant, but the manufacturing soybean income is few, low, the hollow kernels of rate that yields poorly, blossoms and bears fruit, and soybean quality is poor year by year.By surveying soil analysis, and understand peasant planting, fertilization mode, find the following problem of manufacturing soybean ubiquity on the south the Changjiang river to the rural area:
＜one〉be that the peasant does not understand the nutritive property of soybean and inhales fertile rule, blindly plantation, blindly fertilising have destroyed the soil fertility nutrient balance, make the soybeans they grow environmental degradation;
＜two〉be that the peasant is subjected to tradition to use fertile ideal effect, bias toward and use single nitrogenous fertilizer that ignore phosphorus potassium nutrition and trace element collocation, the only long bean seedlings of the soybean of plantation are the result not, a small amount of pod disease and pest is many;
＜three〉be temporarily also not have a kind of beans composite fertilizer special on the southern market, the peasant does not know which type of fertilizer this uses.At this situation, we set about from surveying soil analysis, in conjunction with southern climates and illumination condition, from satisfy the soybean biological characteristic and the growth reproduction inhale fertile rule set about research, develop a kind of composite fertilizer special of specializing in areas to the south, the Changjiang river soybean planting, basically solve the fertile problem of southern soybean planting, filled up this blank.
Soybean planting is different with cash crop such as watermelon, peanuts, and its unique growth characteristic and envrionment conditions requirement are arranged, and is summarized as follows:
＜one〉growth characteristic
1, germination period is when seed germination, and radicle at first extends, and passes kind of a hole and penetrates in the soil, forms main root later on.Secondly plumule also along with upwards elongation, is being with two cotyledons to expose native face, forms cauline leaf, and cotyledon is unearthed to be and emerges.Soybean seeds germinates soon and neat when 18～20 ℃ of mean daily temperatures, and sow 4 days can emerge, absorption 120%～140% the moisture that is equivalent to conduct oneself with dignity during germination.
2, seedling stage, soybean seedling was 20～25 days, and seedling plant strain growth in period is slow, and root growth is very fast, was to be the period of organic centre with the root system, and this phase photosynthate all is used to constitute vegetative organ.Soybean seedling is stronger to the resistivity of low temperature, arid, also needs sufficient nutrition, and the speed of absorbed nitrogen phosphorus is very fast.
3, the bud differentiation of flower bud differentiation period soybean is different because of kind sooner or later, and general branch is also grown from back beginning in 20～30 days bud differentiation of emerging, and therefore also claims the branch phase.Occur from the calyx original hase, nourish and grow and reproductive growth is gone forward side by side, the cauline leaf growth is accelerated, and bud differentiation is rapid, and root system development is vigorous.This phase nitrogen fixing capacity increases, and has half to utilize for plant.Unless fertilizer and water condition is too much, need generally speaking, should in time supply with nutrient and moisture outside the suitably control nourishing body growth.
4, after the bud differentiation in flowering period was finished, petal was open fully, was called and bloomed.Flowering period, society grew the most vigorous period, also was that plant turns to reproductive growth by nourishing and growing, and highly went forward side by side period, and it is the highest in the time of infertility that dry-matter day increases absolute value, and the beginning, the colored assimilation ratio of educating was the highest in the time of infertility.Require enough nutrients and moisture this moment, as the fertility deficiency, need impose quick acting fertilizer.
5, the drum grain phase soybean blossoming after fertilization that bears pods, ovary is expanded thereupon, soft and little cyan beanpod then occurs.This phase fertility growth is occupied an leading position, and no matter the intravital nutritive substance of plant distributing and utilizing, has been photosynthate, or mineral nutrition, all shifts to seed from each position of plant, to satisfy the needs of seed growth.Should prevent later stage under-nutrition this moment.
6, photosynthate all flows to beanpod along with the formation of beanpod the ripening stage.This phase, fertility speed gradual slow stops at last fully, enters the stage of yellow ripeness, and seed moisture content quickly falls to about 17%, and last seed hardening and the city presents the heredity inherent colour is promptly ripe.General maturation is seed completely, and 100-grain weight, protein content and output are all high, otherwise, seed variety, output all there are detrimentally affect.
＜two〉soybean is to the requirement of envrionment conditions
1, the temperature soybean is the warm crop of happiness, and the active accumulated temperature greater than 10 ℃ that different varieties needed between breeding time differs greatly, and late variety is more than 3200 ℃, and the summer sowing early maturing variety then requires about 1600 ℃.The optimum temperature of soybean growth is about 25 ℃, and temperature low then late blooming and maturation reduce the pod rate that connects.During seed was reached maturity, day temperature height, night felt nice and cool, and help closing the accumulation of photosynthate, when temperature is higher than 40 ℃, connects the pod rate and then reduce.Seedling stage the soybean compensation ability stronger, as long as cotyledon is not dead, after the frost, cotyledonary node also branch can occur.The soybean bloom cold tolerance is the poorest, death when temperature drops to 1 ℃.
2, the moisture soybean is to need the more crop of water.According to surveying and determination, every formation 1 gram dry-matter needs 700～1000 milliliters of water consumptions, and is higher 0.4～1 times than wheat, millet.The fastest at soybean blossoming fruiting period plant strain growth, need water maximum, require soil quite moistening.If be obstructed as if soil drought, vine growth and development, exploitation is rare, excessive rainfall, and the cauline leaf over growth, flower bud easily comes off, and all can influence output.
3, the mineral nutrition soybean growth needs to absorb multiple element from soil, denitrogenates, outside the phosphorus, potassium, calcium macroelement, also need absorb trace elements such as molybdenum, manganese, zinc, boron.Data according to the study, every production double centner soybean needs 7.2～8.89 kilograms in nitrogen, 0.84～8.89 kilogram in phosphorus, 2.5～3.12 kilograms in potassium is compared with corn kernel with acquisition double centner wheat, nitrogen is high more than 2 times, and phosphorus, potassium are high 0.5～1 times, and the content of calcium oxide and boron is 10 times of wheat grain.Soybean is at each growthdevelopmental stage, and every day, nitrogen, phosphorus Nutrient Accumulation amount were also inequality.Before from emerging to blooming, the day accumulation volume of nitrogen, phosphorus is less, and be the weight break point that soybean absorbs nutrient the period of blooming, and full-bloom stage is the surge phase that absorbs nutrient, and fruiting period peaks, and drum reduces after the grain phase gradually.Therefore, imposing nitrogen, phosphatic manure in flowering period according to the soybean bearing status, is the important means of soybean yield-increasing.
4, the illumination soybean is typical short day crop.Short day can promote the soybean reproductive growth, suppresses to nourish and grow.The bud differentiation of soybean needs to carry out under short day, long dark condition.In 9～18 hours sunshine scope, light application time is short more, can promote the growth of reproductive organ more; Illumination is long more, and the soybean blossoming maturation is late more, even reproductive organ can not break up.This condition, south have the characteristics that are different from northeast, and south also needs compensate on the fertile proportioning trace element of special use except that the growth time of early sowing with the body that has additional nutrients of trying one's best.
5, the soil soybean requires not strictly to soil, no matter is sandy soil, sandy loam, clay loam or clay, even the indentation soil all can plant, but with thicker soil, be rich in organism and calcareous, draining is good, permeability is better, the potential of hydrogen neutral soil is the most suitable.
Soybean is to the needs of main nutrient elements, and is variant according to the difference of its kind and their location soil, weather condition.Every production double centner soybean kernel needs 7.0～9.5 kilograms in nitrogen (N), phosphorus (P
2O
5) 1.3～1.9 kilograms, potassium (K
2O) 2.5～3.0 kilograms.Soybean is to the demand weight percent of nitrogen phosphorus potassium three elements: N: P: K is 1: 0.23: 0.41.This shows that soybean needs nitrogen a lot, but wherein can pass through nodule nitrogen fixation, nodule nitrogen fixation accounts for 40～60% of the total nitrogen requirement of soybean, and all the other are then from soil and fertilizer.Phosphorus potassium element mainly provides by soil, and the ability that soybean root system absorbs phosphorus potassium is stronger, generally is not that the soil manufacturing soybean that lacks phosphorus, potassium deficiency especially can be satisfied the demand, but wants to make yield and quality to improve, must the increasing application phosphorus potassium fertilizer material.In addition, soybean also needs boron fertilizer and molydbenum fertilizer especially, and wherein molybdenum is relevant with the nodule nitrogen fixation ability, and boron is then relevant with reproductive growth, metabolism, increase oleaginousness.Soybean is divided into 3 growing stages in life, promptly vegetative growth phase, nourish and grow and reproductive growth carries out stage, generative growth phase simultaneously.Drum grain after date is gradually slow in order to absorb two peak periods of nitrogen in branch phase, flowering period for soybean.Soybean just just increases substantially to rousing a grain phase to bearing pods to the absorption of phosphorus.Soybean concentrates on early stage to the needs of potassium, and it is more that the branch phase is inhaled potassium, successively decreases subsequently.
1, the nitrogen nutrition of soybean, soybean nitrogen content height, nitrogen content is generally 6.23%～6.59% in the seed, and cane nitrogen content 1.93% is made 1.3～3 times of object heights than standing grain section.Three kinds of sources of soybean nitrogen are: soil, fertilizer, nodule nitrogen fixation.The symbiotic nitrogen fixation city of soybean carries out in the thalline in root nodule, and the edatope condition is: 20～24 ℃ of adaptability of soil temperature, P in soil H value is 5.7～7.1.The dedicated fertilizer for soybean sources of nitrogen is urea, sulphur ammonium, but definitely can not use ammonium chloride that nitrogen is provided, because ammonium chloride can obviously destroy root nodule bacterium, influences fixed nitrogen.
2, the plain nutrition of the phosphorus of soybean, phosphorus is plain not to have nitrogen many though soybean absorbs, and makes object height than standing grain section, is 1.3～1.7 times of standing grain sections, and phosphorus content accounts for 0.4%～0.5% of amount of dry matter in seed.The energy force rate that absorbs phosphorus during the soybean blossoming is strong 10 times early stage, for inhaling the phosphorus peak.Soybean enters when bearing pods the drum grain, and phosphorus descends owing to shifting to seed in the vegetative organ, and the phosphorus in the flower pod but constantly rises.This moment is plain not enough as phosphorus, then can reduce the content and the operation factor of sugar, and flower pod disengaging rate increases.
3, SOYBEAN POTASSIUM PHYSIOLOGY nutrition, the soybean absorbing potassium capability is stronger, to the absorption of potassium mainly seedling to blooming fruiting period, and fastest, and the potassium peak period occurs inhaling in fruiting period, descend gradually later on, have 40% potassium element to transfer in the beans by cauline leaf in the big Salt black bean pod phase.
4, soybean micro-element nutrition, the required trace element of soybean mainly contains molybdenum, boron, manganese, zinc, sulphur etc.Molybdenum is the integral part of nitrogenase in nitrate reductase and the root nodule in the soybean plant strain, in the plant body, the molybdenum major part is present in root nodule and the blade, the every production double centner of soybean plant strain seed need be inhaled 154 milligrams of molybdenums, when containing molybdenum amount 0.15～0.2 mg/kg in the soil, execute the molydbenum fertilizer obvious effect of increasing production.Soybean is relatively more responsive to the reaction of manganese, when containing manganese in the plant and be less than 10 mg/kg, and will manganese deficiency.Soybean is for happiness sulphur crop, to sulfur fertilizer demand height, during a lack of sulfur the young leaves light green to yellow, the aged blade of the late growth stage chlorosis of also turning to be yellow, and brown spot occurs, plant is thin and delicate, root system is tall and thin, the root nodule dysplasia enriches sulfur fertilizer and can improve protein content and quality.Soybean is also responsive to zinc, and suction zinc amount is more than other crops, mainly is distributed in root system, promotes growth hormone synthetic.Boron can improve the activity of invertase in the soybean body, promotes carbohydrate transport, improves the root nodule bacterium activity, increases amount of nitrogen fixation.Boron can also promote formation and the seed development of flower pod, strengthens soybean resistance.
Soybean lacks any nutritive element and all can destroy the intravital eubolism of plant in growth and development process, finally causes output to descend the grain quality variation.The soybean nutritional deficiency symptom is analyzed as follows:
1, during nitrogen stress soybean nitrogen stress, plant strain growth is slow, and is short and small and thin and delicate.Simultaneously, nitrogen stress causes that chlorophyll content reduces, and plant lower blade green is shoaled, and is light green, and flavescence is withered gradually later on.Because the nitrogen deficiency, bronze speckle appears in big sometimes bean flour, and during serious nitrogen stress, plant strain growth stops, and blade comes off gradually.When the nitrogen stress symptom occurring, it is effective to impose fertilizer such as instant nitrogenousfertilizer such as ammonium nitrate, urea, ammonium sulfate.
2, lack the phosphorus soybean and lack phosphorus, various metabolic processes are suppressed, plant strain growth is slow, the leaf cell dysplasia, the degree that cell diminishes reduces degree greater than chlorophyll again, and chlorophyll density is improved relatively, and the leaf look is dark green or greyish-green, later minus green between the vein of lower curtate leaf, last vein minus green death.When scarce phosphorus was serious, brown spot appearred in blade, and red striped or spot may appear in cane, and it is brown that root turns.Phosphorus content in the soybean plant strain is 0.25%～0.35% o'clock, and the plain nutrition of expression phosphorus is suitable.
When 3, potassium deficiency symptom appears in potassium deficiency, edge generation macula lutea point between leaf, tissue necrosis gradually, or from older blade with organize browning look, yellow, delayed growth.The potassium deficiency soybean is born pods few, and pod is little and not full, and beans size inequality is deformity.The soybean protein quality reduces.In south, soil is potassium deficiency in various degree, and yellow disease often appears in soybean, and the yellow of early soybean potassium deficiency generally began to take place at ripe 25～32 days, and when extremely serious, the lobus cardiacus of plant also can flavescence.This is the basic reason that has a strong impact on output.
4, lack the molybdenum soybean and lack molybdenum, retarded growth, plant is short and small, minus green between vein, or leaf curling, the root nodule dysplasia, quantity is few, and volume is little, and nitrogenase activity reduces, and amount of nitrogen fixation reduces.
5, during boron deficiency soybean boron deficiency, poor growth, leaf look light rate, the blade face is uneven, root system development is bad, and root nodule is not only undeveloped, even loses nitrogen fixing capacity, and, the death of plant shoot apical meristem, bud are in early development death, and influence is bloomed to bear pods and counted and pollen formation and fertilization.
Summary of the invention
Order of the present invention is to provide a kind of special-purpose fertile, and a kind of dedicated fertilizer for soybean particularly is provided, and has satisfied nutritional need in the soybeans they grow reproductive process, and contains and nutritive ingredients such as nitric nitrogen, sulfate radical, boron, molybdenum, helps soybean nodulation fixed nitrogen.
Order of the present invention is realized in the following way:
＜1〉nitrogen provides, and provides the nitrogen nutrient by urea, sulphur ammonium, ammonium nitrate etc., also has distinct advantages to provide nitric nitrogen with ammonium nitrate, helps promoting nodule nitrogen fixation.
＜2〉the phosphorus element provides, and provides the phosphorus nutrient better by general calcium, except that phosphorus is provided, also contains CaSO
4, supply calcium constituent and thionin can improve Soil structure.
＜3〉the potassium element provides, and is better than Repone K with vitriolate of tartar according to one's analysis, more helps soybeans they grow, as from considering economically, with import Repone K instead of part vitriolate of tartar, but definitely can not use Qinghai potassium, to avoid muriate harm.
＜4〉Glycine happiness sulphur crop all can provide the sulphur nutrient with sulphur ammonium, vitriolate of tartar, general calcium, is enough to satisfy the soybeans they grow needs.
＜5〉taboo provides the nitrogenous source prescription with ammonium chloride, in order to avoid root nodule bacterium are done great damage.
＜6〉rainfall is plentiful on the south the Changjiang river, if special-purpose fertilizer solvability is very good, fertilizer efficiency weak point, later stage fertilizer deficiency situation will occur, therefore requires long-acting alleviation, except that considering material matching, also should use additive such as sepiolite, fused(calcium magnesium)phosphate etc. with slow releasing function.
＜7〉for avoiding the trace element deficiency shape appears in the soybean growth process, according to surveying the soil analysis data, with ammonium molybdate, borax, manganous sulfate, zinc sulfate by 4: 2: 1: 1 weight percent is made into micro fertilizer special, add with 1.2～1.5% weight percents when producing dedicated fertilizer for soybean, can fully satisfy the demand.
＜8〉dedicated fertilizer for soybean element nitrogen, phosphorus element, the plain element weight percent of potassium are nitrogen: phosphorus: potassium=0.4～1: 0.1～0.3: 0.2～0.4, suitable weight percent is a nitrogen: phosphorus: potassium=1: 0.2: 0.3, the nitrogen that provides because of nodule nitrogen fixation accounts for the total nitrogen requirement 40～60% of soybean.Therefore, the actual formulation weight per-cent of dedicated fertilizer for soybean should be nitrogen: phosphorus: potassium=5: 2: 3.
The present invention has complete, the rational characteristics of filling a prescription of nutrient, has fully satisfied nutritional need in the soybeans they grow reproductive process, and contains and nutritive ingredient such as nitric nitrogen, sulfate radical, boron, molybdenum, helps soybean nodulation fixed nitrogen, and cl content is few, endangers little.Dedicated fertilizer for soybean and calendar year 2001,2002 with these prescriptions are rendered to Xinyang, Henan, Jing Zhou, Hubei and Jianli, Xianning Prefecture, Dongting Lake zone, Hunan, area, the western Hunan etc., all obtained good effect, be embodied in: the soybean growing way is good, blooming, it is many to bear pods, empty pod rate is low, full seed, maturation was carried about the last week.It is believed that some plantation family reflections of Jing Zhou, changed the acarpous situation of only long in the past bean seedlings fully with this special use fertilizer, the soybean kernel 100-grain weight increases about 10～15%, per mu yield has then increased more than 20%, and the soybean particle shape is uniform and smooth, and color and luster is equal, be not inferior to northeast soybean in quality, therefore the peasant is full of confidence to manufacturing soybean, claims this special use fertile " grain " for soybean, " real composite fertilizer ".
