Abstract
The present invention relates to one kind of fertilizer specially for Chinese onion. The fertilizer consists of urea, potassium sulfate thiamine, monoammonium phosphate, ordinary superphosphate and special additive; and has the composition of N: P2O5: K2O of 9-12 to 5-8 to 13-15. Applying the fertilizer with reasonable composition can raise the yield and quality of Chinese onion greatly.
Description
Technical field
It is special-purpose fertile to the present invention relates to a kind of Onion head.
Background technology
The Onion head is short high-yield crop of a kind of production cycle, and per mu yield can reach more than 2000 kilograms, is a kind of cash crop that can create higher benefit.But the peasant adopted urea, common composite fertilizer to make base manure in the past, be aided with the fertilizing method that the vitriolate of tartar work topdresses with common composite fertilizer again, this method is used complexity, and effect is not fine, per mu yield is difficult to above 1500 kilograms, the enthusiasm that the peasant plants the Onion head is not very high, and supply falls short of demand to cause local Onion head.
Summary of the invention
The objective of the invention is to provide a kind of Onion composite fertilizer special, this special use fertilizer is the compound potassium sulfate fertilizer at the growth rhythm of Onion head and the production of nutrient uptake feature proportioning, can satisfy the needs of Onion head growth growth period to nitrogen, phosphorus, potassium nutrition element, particularly to the needs of sulphur, potassium, complicated problems is used in solution, and improves application effect.
The objective of the invention is to realize in the following way: contain urea, vitriolate of tartar, sulphur ammonium, monoammonium phosphate, general calcium, specialist additive in the special-purpose fertilizer of Onion head, its prescription is N: P
2O
5: K
2O=9 ~ 12: 5 ~ 8: 13 ~ 15.
Onion root system belongs to string of a musical instrument shape fibrous root system, and a little less than the suction fertilizer sucting ability, it is shallow to distribute, and main root system concentrates in 5～25 centimetres the topsoil, need to select fertile, topsoil is deep, quality profit pine, organicly enrich, sand loam soil that preserve moisture and fertility power is strong.Clay ground soil property is glutinous heavy, is unfavorable for that root of hair and bulb expand.Sandy soil ground, grittiness is strong, and it is poor to protect fertile water retention capacity, yields poorly.The saltings, alkalescence is big, and seedling causes Huang Ye and dead seedling easily to salt alkali reaction sensitivity.About suitable soil pH 6-8, if pH4-6, then can the underproduction or do not have harvest.The Onion head is maximum with potassium to the absorbed dose of nutritive substance, and nitrogen, phosphorus, calcium take second place.A large amount of experimental datas show that the Onion head is 2.6: 1: 3.5 to the ratio that nitrogen, phosphorus, potassium absorb.Main nutrient elements is to the physiological action of Onion head:
Nitrogen: nitrogen to Onion leaf growth, bulb expand and the raising of output all has great influence.
The phosphorus element: phosphorus can improve the blade water-retentivity, strengthens intensity of photosynthesis, increases ascorbic content, strengthens the activity of plant peroxidase, can improve the bulb yield and quality.
The potassium element: potassium is Onion the element that absorbed dose is maximum, and strong to the movability of young leaves from Lao Ye.Potassium is to the running of Onion nutrient and promote bulb to expand etc. desirable influence is all arranged.
Calcium: calcium surpasses phosphorus in the dietetic alimentation of Onion head.Calcium is poor mobility in vivo, when not enough, and the vegetative point necrosis of root and stem.
Sulphur: sulphur is the composition of vitamins B and propylene sulfide base, and to execute sulphur significant to improving Onion quality and local flavor more.When sulphur was not enough, the leaf flavescence was given birth to bad.
Magnesium: magnesium is chlorophyllous composition, magnesium deficiency, the yellow of leaf chlorosis.
The fertilizer-sucting quantity that experimental results show that the Onion head is compared with amount of application, and absorbed dose is very low.The absorbed dose of nitrogen is about 25% of amount of application; The absorbed dose of phosphorus is about 10%～20% of amount of application; It is close that the absorbed dose of potassium is about amount of application; The absorption of calcium only is 5%～10% of an amount of application.Therefore rate of fertilizer application generally is greater than recommended fertilizer on producing.
Onion crop is the same with field crop, and each growth and development stage all has different requirements to kind, quantity and the ratio of nutritive element, the stage of crop absorption nutrition that Here it is.The rule that crop absorbs nutrient is: quantity, intensity that early growth period absorbs are all lower, strengthen gradually subsequently, to the stage of maturity, are tending towards again weakening.The Onion head enters the seedling phase after being unearthed from germinateing, though the long successively root foliation of seedling this moment, growth of seedling is slow, and increment is little, and fertilizer requirement is few; After seedling turned green, increment strengthened, and fertilizer requirement also increases, and particularly root system preferentially increases, and root amount and root length increase sharply, and fertilizer requirement and the fertile intensity of suction increase rapidly, and secondary root Sheng enters the tiller phase after the phase, and fertilizer requirement increases severely, and inhales fertile intensity and also peaks.
The shortage of trace element means the forfeiture of important metabolic function in the plant materials, thereby the results quality is descended.Trace element is vital to people's health, itself also is a kind of quality index sometimes.In the vegetable products, content of elements is widely different.Then can produce toxin when micronutrient levels is too high.Though the trace element requirement is few, very big to the influence of growing of Onion head, when manganese was not enough, plant lodged easily, and output reduces; When copper is not enough, the leaf sheath attenuation, bulb protects Ye Yese thin out outward; But manganese, copper hyperabsorption also can significantly suppress to grow and become fertilizer damage.When boron was not enough, leaf development was obstructed, and bulb is consolidation not, and easily heartrot takes place.
Owing to consider that the chemical property of chemical fertilizer itself has slightly acidic, long-term application can cause the hardening of soil, acidifying, the front has been mentioned as if pH in soil in 4 ∽ 6, can cause the underproduction or not have harvest, therefore, we have added the weakly alkaline material in specialist additive, the special-purpose fertile pH that strict control is produced is between 7 ∽ 7.5, to adapt to the growth of Onion head, simultaneously, trace element manganese, copper and boron have been added therein.
Because chlorine participates in photosynthesis, keeps charge balance and turgescence in the cell, an amount of chlorine helps the synthetic of carbohydrate and transforms, and improves the disease resistance of crop, is indispensable element.
Adopt the present invention, because the special-purpose fertile reasonable ratio of Onion head can improve Onion output after rationally using greatly, optimize Onion quality, and after using this special-purpose fertilizer, do not need to use other single fertilizer such as urea, phosphate fertilizer etc., use easily, market outlook are good.
