Fertilising, watering, weeding, the diseases prevention management respectively handled is identical.Experimental plot peanut demonstration test corn is opened on the 7th in September
Begin harvest, and harvesting time-division cell individually harvests, individually weighs, calculates each cell production.
Influence of 2.1 different disposals for corn yield
Test result show Yield-increasing Baallus In Maize auxotype water conservation loosen the soil complex fertilizer processing average product be 786.6 kilograms/
Mu increases 65.2-85.5 kgs/acre, rate of growth 9.04%-12.20% with than compareing.
Influence of 1 different disposal of table to corn yield
Influence of 2.2 different disposals for the soil weight
The soil weight refers to the quality of unit volume original-state soil dry ground.Soil weight size reflects soil texture, breathes freely
The height of property, water permeability and water holding capacity, the soil weight is smaller to illustrate that soil texture, air-and water-permeable performance are better.
For different disposal, soil weight measurement is carried out to each processing in corn growth season, specific assay method is：To each
Cell carries out five point samplings, acquires the soil layer of 5-10cm depth, individually measures its soil weight, be averaged later, obtain
To each processing soil weight, measurement result is as shown in the following table 2.
The soil weight (unit when table 2 respectively handles harvest：g/cm3)
After the data of table 2 can be seen that the complex fertilizer that loosens the soil using auxotype of the present invention water conservation, relative comparison fertilizer,
The soil weight has different degrees of reduction, this illustrates that the auxotype water conservation of the present invention loosens the soil complex fertilizer with apparent effect of loosening the soil
Fruit, this is conducive to the volume increase of crop, increases income.
The innovation of the invention consists in that selecting chitin, chitosan and gamma-polyglutamic acid liquid compounding as complex fertilizer
It is retained the ingredient that loosens the soil, chitin, chitosan and gamma-polyglutamic acid water conservation, flocculation is given full play to, breaches in conventional fertilizers
The inorganic water-keeping material of addition chemistry, i.e., the harmful substance present in polyacrylamide, acrylates, polyaluminium chloride etc. increases and production
The single limitation of product effect, effectively overcome arid area and sand area, water shortage, not water holding, non-fertilizer conservation, intolerant to
Drought, nutrient are easy to be lost in a series of problems, such as causing crop production reduction, soil erosion.Meanwhile making full use of China's pharmacy, enzyme system
A large amount of mycelium residues that agent, Citric Acid Production generate are organically combined, cooperation using physics steam explosion technology and enzymolysis deacylation technique
Trace element chelated technique, produces good water-retaining property, effective water conservation of loosening the soil is loosened the soil agent, and abundance is cheap,
At low cost, effect is good, can be widely used in complex fertilizer production, and peasant is easily accepted by, and is conducive to batch production large-scale production and utilizes.Together
When, the present invention is retained the advantages of complex fertilizer that loosens the soil also has both chitin and gamma-polyglutamic acid fertilizer, and it is respective to give full play to its
Advantageous effect, using soil, cocoa effectively improves soil aggregate structure, effectively improves soil, improves soil water-retaining, fertilizer conservation energy
Power improves the living environment of crop, breaks the bridging of soil intermediate ion, reduces soil hardening, the potentiality that Yan Zi Eng occurs, increases
Strong soil ion exchange capacity, improves soil physical chemistry environment and micro-ecological environment, promotes crop root growth development, promotes crop
Absorption to nutrient.
Chitin is extracted from natural shrimp shell, crab shell or microbial mycelial, is had with a kind of environmentally protective
Machine high polymer coagulant imposes on the adsorbable soil particle of soil containing hydroxyl, carboxyl, amino and other active groups, is formed
Soil aggregate structure, and adsorption moisture achieve the purpose that water conservation is loosened the soil.Fungal mycelium is an important sources of chitin,
Pharmacy, enzyme preparation, organic acid fermentation process generate a large amount of waste mycelias, typically contain 20-40%'s in these mycelial cell walls
Chitin and chitosan.China is pharmacy, enzyme preparation, organic acid especially Citric Acid Production big country, there is a large amount of fermented hypha
Body residue, this is agriculturally using providing high-quality cheap raw material.
Gamma-polyglutamic acid has splendid biodegradability, film forming, at fibroid, plasticity, caking property, superpower
Much unique physics and chemistry such as hydrophily and water holding capacity and biological characteristics.It is large-scale that it can have the technology of biofermentation
