A kind of Sugarcane Fertilization method
Technical field
The present invention relates to technical field of fertilizers, specifically a kind of Sugarcane Fertilization method.
Background technique
In current sugarcane production, due to labor cost soaring and sugarcane procurement price it is dispirited, sugarcane grower's large area subtracts
Lack new plant cane and constantly expand stubble cane area, and the stubble cane time limit also extends year by year, therefore pest is also cured causing harm for sugarcane
More it weighs, wherein sugarcane borer, grub are especially prominent to the harm of sugarcane.Sugarcane borer is all harmful in sugarcane entire growth period, and seedling stage is
Evil growing point causes withered heart seedling, and withered heart rate is generally 10%~20%, serious up to 50% or more, and middle and later periods brill moth causes harm sugarcane
Stem destroys sugarcane stem tissue, hinders sugarcane production, causes windbreak, reduces yield and sugar.
And long-term continuous cropping plantation, the method for the supplement sugarcane nutrient mainly base into soil are applied, spread fertilizer over the fields quick-acting chemical fertilizer, it is long
Phase applies quick-acting chemical fertilizer and ignores the organic fertilizer enough to soil application, and the soil organism is caused to lack, and the content of organic matter is
One important indicator of soil fertility and crumb structure, soil organic matter content is low, influences the activity of microorganism, to influence soil
The formation of earth crumb structure, leads to soil hardening.
Humic acid is that the remains of animals and plants are formed through a series of transition process of microorganism decomposition and conversion and natures
A kind of organic substance, be widely present in nature, soil, waters, coal, shale and earth's surface.Humic acid can be to pesticide
The effect for playing sustained-release synergistic, slowing down decomposition, reducing toxicity, extend drug effect, reducing dosage, is much tested and is practiced institute
It confirms.Illustrate humic acid and agriculture in " humic acid and the pesticide attenuation synergistic " delivered such as the Feng Yuanqi of China Humic Acid Industry Association
Medicine combines, and drug effect can be improved, and extends drug effect phase (5~7d), and reducing dosage, (insecticide reduces dosage 30% or so, sterilization
Agent dosage reduces 50% or so), and toxic hazard can be reduced.Humic acid is a kind of organic colloid, inner surface and colloid surface
Larger, strong adsorption is accumulated, a variety of mineral elements in adsorbable, exchange and activating soil can improve the permeability of soil, increase soil
Earth retain water and nutrients ability reduces soil water evaporation, increases soil cation exchange capacity (CEC), is conducive to plant to each nutrient
Absorption, with Soil building, improve soil aggregate structure, improve immunity and promote crop growth.
In view of two main problems in the above sugarcane production, it is a kind of can improve soil texture and can prevent and treat sugarcane moth borer,
Subterranean pest-insect organic fertilizer is just particularly important.The organic fertilizer compounded using pesticide with humic acid is had in pest control
Synergistic function, while the fertility of soil can be improved again.
Currently, using the organic fertilizer of chlopyrifos, Cupric sulfate and humic acid mixture, there are no relevant reports.
