Description
Technical field
The present invention relates to special fertilizer, be specifically related to a kind of Ipomoea batatas special fertilizer.
Background technology
Ipomoea batatas is a kind of main rain fed crops of China, plays an important role to the life of people and industrial raw materials.
Ipomoea batatas has following several outstanding feature in cultivation: one be Ipomoea batatas is deep rooted plant, and impoverishment tolerant ability is strong, and entirety needs rich water flat lower, it often produces 50kg Ipomoea batatas, needs to absorb nitrogen and is about 1.75kg, phosphorus element 0.75kg, potassium element 3.0kg, its ratio is roughly 3:1:5; Two is the not resistance to continuous croppings of Ipomoea batatas, and the sick parasitosis of continuous cropping Ipomoea batatas is serious, yield poorly, and anti-continuous cropping is the key of Ipomoea batatas high yield; Three is that Ipomoea batatas insect pest is many, and the General Loss rate caused Ipomoea batatas is about 10%.
So Ipomoea batatas should be different from the farm crop such as wheat, corn with fertilizer.Ipomoea batatas fertilizer should reduce the amount of nitrogen, phosphorus, and should increase the consumption of potash fertilizer and the consumption of fertilizer, the particularly consumption of bio-fertilizer, utilize the bio-fertilizer in fertilizer, activation phosphorus potassium and other medium trace element, anti-continuous cropping, have pest-resistant, insecticidal function simultaneously concurrently, improve the seed output and quality of Ipomoea batatas.
But the Ipomoea batatas of reality is fertile, still continue to use the fertile knowledge of other farm crop and custom, for improving Ipomoea batatas output, a large amount of use chemical fertilizer, can not take into account the various nutrient demands of Ipomoea batatas, illly cures the disease, there is worm to control worm, use agricultural chemicals in a large number, drastically influence Ipomoea batatas good quality and high output.
Summary of the invention
For Ipomoea batatas fertilising Problems existing described above, the invention provides a kind of special fertilizer of applicable Ipomoea batatas good quality and high output.
The technical solution used in the present invention, designed Ipomoea batatas special fertilizer is made up of following raw material:
Microbiobacterial agent 5-15 part, insecticidal microorganism microbial inoculum 5-15 part, zinc sulfate 0.5-1 part, borax 0.5-1 part, magnesium sulfate 1-2 part, clay 5-15 part, is rich in chemical fertilizer 50-78 part of N P and K.
Described microbiobacterial agent is made up of one or more in Bacillus licheniformis, Bacillus cereus, bacillus megaterium, Bacillus mucilaginosus, subtilis, Tribactur.Its You effect Huo Jun≤200,000,000/gram, water content is no more than complex micro organism fungicide standard.
Described insecticidal microorganism microbial inoculum is made up of chafer genus bacillus, muscardine, green muscardine fungus.They, through cultivating, are dried to water content about 15%.
The described chemical fertilizer composition being rich in N P and K is allocated by monoammonium phosphate, calcium superphosphate, ammonium sulfate, potassium sulfate, urea, after allotment, the nitrogen in special fertilizer, Vanadium Pentoxide in FLAKES, potassium oxide weight percent is made to reach 8%-10%, 6%-8%, 12%-14% respectively.
The present invention adopts above-mentioned raw materials to prepare Ipomoea batatas special fertilizer, be due to:
Its function of microbiobacterial agent has following eight large functions: one, the organic and inorganic nutrient of activating soil, improvement soil, and elimination is hardened, and improves preserve moisture and fertility ability, increases soil fertility; Two, anti-Ipomoea batatas continuous cropping obstacle, it improves the supply of sweet potato nutrient, and eliminates the obstacle of Ipomoea batatas continuous cropping; Three, improve soil microorganisms flora, improve soil microenvironment, suppress soil surface characters breeding, effectively can prevent the disease such as root-rot, black spot of crop, and drive harmful organism if grub etc. is at this plot growth and breeding; Four, the utilization ratio of chemical fertilizer is improved; Five, can root growth be promoted, strengthen receptivity, improve Ipomoea batatas drought resisting, degeneration-resistant; Six, significantly reduce heavy metal-polluted soil and saline and alkaline etc. Ipomoea batatas to be poisoned, reducing the residual of agricultural chemicals; Seven, the seed output and quality of Ipomoea batatas is improved.
Insecticidal microorganism microbial inoculum: it has outside the function of microbiobacterial agent, can also kill the sick worm that part is harmful to farm crop.
Zinc sulfate: the growth that can promote Ipomoea batatas, improves its photosynthetic efficiency, improves its anti-adversity ability, improves output.
Borax: the boron in it promotes root growth, improves photosynthetic efficiency, promotes that its physiological activity and the solid of Ipomoea batatas are expanded, and improves output.
Magnesium sulfate: ensure the normal physiological activity of Ipomoea batatas, carry out normal photosynthesis, prevent crop chlorosis etc.
Clay: described clay is a kind of, soil of having stickiness few containing the grains of sand, various fertilizer material can be bonded into particle.Containing multiple hydrosilicate and a certain amount of metal oxide in clay, also comprising a small amount of magnesium, iron, sodium, potassium and calcium, is a kind of important raw mineral materials.
Be rich in the chemical fertilizer of N P and K: refer to the fertilizer produced with chemical synthesis process, be rich in nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide.Mainly contain urea, ammonium sulfate, ammonium nitrate, monoammonium phosphate, calcium superphosphate, diammonium phosphate, potassium sulfate etc.Described zinc sulfate, borax, magnesium sulfate are other industrial goods of agricultural grade.
The preparation method of Ipomoea batatas special fertilizer of the present invention adopts traditional preparation method, by the raw material compound of certain part by weight or can mix up together, and cause grain; Also can be directly blended together, or blended together after respective granulation.
The Ipomoea batatas special fertilizer that the present invention adopts the raw material described in technique scheme to be prepared from, owing to adding appropriate, that organic content is high bio-fertilizer, possess organic-the functional effect of inorganic composite mixed fertilizer, and a large amount of biological bacteria in it, serve activation phosphorus potassium and the effect of medium trace element and the effect of other biological bacteria, adding the function of fertilizer, as being compounded with again the microorganism with insecticidal function in product, making product have insecticidal action; The fertilizer effect of the fertilizer improved, is more suitable for Ipomoea batatas and uses.Its directivity, specific aim are clear and definite, and effect is very outstanding.
