Description
Technical field
The present invention relates to technical field of fertilizers, and in particular to a kind of corn resistance physiology slow release fertilizer synergist and its system
Preparation Method and application.
Background technique
Fertilizer is the important means of production of agricultural industry development, for promoting high-quality crop, high yield and stable yields, ensures grain
Safety has irreplaceable role.Chemical fertilizer is cereal crops " grain ", and grain yield is in a linear relationship with applying quantity of chemical fertilizer.
In order to improve the crop yield of unit area, soil applying fertilizer amount increases year after year.Statistics shows in the latest 20 years, China
Fertile amount of application increases to 6348.7 ten thousand tons by more than 3,850 ten thousand tons；Up to the present, China's fertilizer amount accounts for world Fertilizer dosage
31%, it is equivalent to 4 times of world's average dose；Excessive fertilization leads to the reduction of fertilizer marginal efficiency, and chemical fertilizer utilization ratio reduces.Statistics
Data shows: 2015-2017, China's maize sown area 3544.5~3811.9 ten thousand hectare, total output 2.1589~
2.2463 hundred million tons (6090.8 kilogram/hectare of per unit area yield).It is calculated by 225 kilograms of per hectare purity nitrogen, needs 481 kilogram/hectare of urea, often
Urea amount 1705~18,340,000 ton that year applies into soil.This season utilization rate is calculated by 32.5%, and annual number of dropouts 1151~
12380000 tons, cause economic loss 234.8~252.6 hundred million yuan (calculating by 2040 yuan/ton of urea).Excessive applied nitrogen, not only
Huge economic loss is caused, moreover, also resulting in soil organic matter content reduction；Soil texture is deteriorated, bulk density increases, porosity
It reduces；Edaphon mushroom quantity is reduced and bacterium colony type is out of proportion；It is lost between N P and K and microelement available nutrient
Balance；Farmland quality is degenerated；Maize production enhances the dependence of chemical fertilizer.Also, excessive applied nitrogen, leads to corn kernel nitrogen
Element and protein content increase, still, amino acid content proportional imbalance, nutritional quality decline.Therefore, development of new nitrogen manure
Synergist on the basis of ensureing that corn efficiently produces, reduces amount of application of nitrogen fertilizer, to corn by improving chemical fertilizer utilization efficiency
Industry development has great theoretical and practical significance.
Existing research shows using conventional cultivation and fertilizer practice, to a certain extent, can be improved utilization rate of fertilizer,
Reduce pollution by chemical fertilizer.First, farmyard manure, including stalk, animal wastes, green manure etc. are increased, by increasing soil organic matter content,
Improve Ecological Distribution of Soil Microorganisms environment, improve soil texture, improve the suction fertilizer and nutrient preserving capability of soil, increases soil colloid counterweight
The adsorption capacity of the noxious materials such as metal.Second, it, can be by determining dose, fertilization type, applying using rational application of fertilizers technology
Fertile period ensures the balance supply of soil nutrient, reduces the waste of chemical fertilizer, avoid polluting soil environment.Third is improved
Fertilizing method, such as: the depth of ammonium hydrogen carbonate, which is applied, can be improved using 31%~32%, and urea can be improved 5%~12.7%.But often
Rule cultivation and fertilizer practice have investment high, and slow effect, application conditions are restricted, and application effect is limited, moreover, there is negative effect
Fruit, therefore, popularizing area are limited.Such as: straw-returning needs large-scale agricultural machinery, moreover, not being suitable for Northeast plain low temperature cold
Cool area, and easily aggravate the harm of soil pest and disease damage；China's soil types is complicated and changeable, and essence amount rational application of fertilizers practical operation is tired
It is difficult；N-dressed deeply needs large farm machinery to support.Therefore, although conventional cultivation and measures of fertilizer have certain effect, but promote
It is limited.
The study found that it is modified by chemical fertilizer, delay the rate of release of available nutrient, it is possible to reduce fertilizer application frequency mentions
High fertilizer utilization efficiency.In fertilizer modification technology, firstly, fertilizer coating technology (zeolite coated, starch coating, coated with resin,
Sulphur coating etc.), by the physics stopping effect of film phase substance, delay the rate of release of fertilizer, improve nutrient availability, reduces
Nutrient loss extends the nutrient lasting period.But this technology is found in application process, zeolite and starch coating delay to discharge
Effect is poor, little with common fertilizer rate of release difference；Resin is coated extended release significant effect, still, the resin in topsoil soils
Shell white pollution seriously affects the development of crop root；Sulphur coating is unsuitable for acid soil in the south, easily causes soil acidification.Its
Secondary, on physiology level, scientist adds ureaformaldehyde, nitrification inhibitor and urease inhibitor in fertilizer, it is desirable to by dry
The digestion in the soil of urea and nitrate nitrogen, denitrification process are disturbed, nitrogen loss is reduced, extends the lasting period of nitrogen, improves nitrogen
Plain utilization rate.But find in practical applications, ureaformaldehyde decomposition is related to microorganism, is influenced by temperature, humidity, and urea
Formaldehyde is not suitable for dry crop；Region more than nitrification enzyme inhibitor and the unsuitable paddy field of urease inhibitor or precipitation, because of water
The concentration of nitrifying ferment and urease inhibitor can be reduced, validity is reduced；Also, such product does not reduce the function of urea loss
Energy.Therefore, from metabolism physiology and the physiological angle of hormone, the molecular structure of fertilizer is improved by physiological method and there are shapes
State improves the available state and rate of release of fertilizer in soil；By improving the physiological metabolism of crop, improves crop and absorb, assimilate
The ability of nitrogen manure improves the validity of chemical fertilizer especially nitrogen manure, it appears extremely urgent and important.
