Abstract
The present invention relates to a quickly-acting and slowly-released special-purpose formula fertilizer for cotton. Said special-purpose formula fertilizer is made up by mixing quickly-acting complex fertilizer formed from elements of N,P2O5,K2O,B and Zn with coated slowly-released complex fertilizer, in which the total content of nitrogen, phosphorus and potassium is 40%-45%; the weight mixing ratio of N1P2O5,K2O, B and Zn is 1:0.4-0.6:1.0-1.2:0.01-0.02: 0.01-0.02.
Description
Technical field
The invention belongs to technical field of agricultural fertilizers, specifically a kind of by quick-acting composite fertilizers and the coated slow-release composite fertilizer cotton formula fertilizer that forms of blending in proportion.
Background technology
Cotton is the use rich and influential family of Nonrenewable resources petroleum chemicals in the field crop (chemical fertilizer, agricultural chemicals etc.), and the chemical fertilizer usage quantity of cotton all occupies first place and high in China staple crops, and fertilizer cost accounts for plants about 50% of cotton material cost.Cotton needs macroelement and trace element fertilizer in life, belongs to all nutrition type crop, is the higher crop of Fertilization Level in the field crop.Applying fertilizers scientifically helps improving output of cotton, improves quality, reduces production costs, and reduces and pollutes.Cotton is different from food crop such as corn, paddy rice, wheat, it is fibre crops, be again oil crops, breeding time is longer, and it is long overlapping time with reproductive growth to nourish and grow, add cotton and have the characteristic of indeterminate growth, all these makes that the problem of fertilization of cotton is complicated and important more.Current, mainly there are problems such as fertilizer amount is excessive, application process is improper, utilization rate of fertilizer is low, fertilising complex procedures in existing cotton common fertilizer and application process thereof, mainly show following aspect:
The one, utilization ratio is low.Common fertilizer is strong to the dependency of fertilizer practice.Do not having under the good measures of fertilizer, using the back snap-out release in soil, causing relatively large loss.Change into NH as nitrogenous fertilizer
3Directly volatilization or under nitrobacteria effect is converted into NO
3 -, the water that permeates the ground thereby leaching loss appears or, NO
3 -Under the effect of denitrifying bacterium, be converted into NO, N again
2O, N
2And volatilize, after being manured into soil, fixed in a large number by phosphate fertilizer, and after potash fertilizer is manured into soil, on sand, with rainwater more leaching loss appears especially.This season utilization ratio of China's chemical fertilizer is low at present, and nitrogen is 30%～35%, and phosphorus is 10%～20%, and potassium is 30%～50%, than low tens percentage points of world average level.China every year has been caused the waste of several ten million tons of chemical fertilizer resources, hundred million yuan of financial loss hundreds ofs because of excessive applied nitrogen blindly.
The 2nd, to the influence of environment.Because the plant recovery of nutrient of common fertilizer is low, the chemical fertilizer of loss also causes the pollution of environment to some extent.Drip washing as N, P element causes surface water eutrophication and phreatic nitrate to exceed standard, and these pollute influences agricultural-food, the health that endangers people at last by food and drinking water again.Gas purging such as methane, Nitrous Oxide causes the global warming gap effect.Because chemical fertilizer utilization ratio is low, the use of excess chemical fertilizer also causes the destruction of soil aggregate, and soil physical property is degenerated.
The 3rd, cotton conventional fertilizer application a multitude of names has base manure, send and transfer fertilizer, seed manure, flower bud fertilizer (balance fertilizer), main fertilizer, Hua Lingfei, caping fertilizer etc., be a complicated operations operation, often, the worker employed in a plant nursery is many, fertilizer efficiency is low, and especially manuring late difficulty is bigger, has influenced the raising of cotton comprehensive benefit.
In addition, the land area of China peasant household present stage is small and scattered, and the farmingization service system is difficult to set up and put in place, and rational application of fertilizers and other technical measures are difficult to the service that the peasant provides convenience; Simultaneously, owing to many reasons such as income and expenditures, cause be unwilling the time and efforts that in agronomy operation such as topdress, costs a lot of money of many regional peasants.
Therefore, change the form of chemical fertilizer, thoroughly change fertilizer, improve the utilization ratio of chemical fertilizer, reduce pollution, become the common problem of paying close attention in countries in the world because of causing to fertilize for fertile mode and performance.In recent years, releasing one after another of release fertilizer greatly reduces the loss of fertilizer, and the new and high technology of chemical fertilizer technology is low and reduce environmental pollution problems and proposed new thinking and approach for fundamentally solving utilization rate of fertilizer.At present, some slow-releasing fertilizer of domestic development, as coating urea, fused(calcium magnesium)phosphate parcel carbon ammonium, long-term efficiency bicarbonate ammonium etc., be mainly used in the higher crop of economic worth, actual on cotton, use then less, its major cause: the one, price problem, compare with common fertilizer, the production cost of film-coated controlled release fertilizer is higher 1～2 times than conventional fertilizer; The 2nd, slowly/controlled releasing fertilizer mainly stresses nitrogen nutrient, and is less to the controlled release research of nutrients such as phosphorus potassium; The 3rd, be to have emphasized slowly-releasing in the research of slow release fertilizer unilaterally, ignored short releasing, be difficult to accomplish discharge with the cotton regulation of fertilizer requirement synchronously with nutrient, often cause cotton growth fertilizer deficiency in early stage and later stage to take off fertilizer, and mid-term over growth; The 4th, cotton development stage is longer, and it is long overlapping time with reproductive growth to nourish and grow, and adds the characteristic that cotton has indeterminate growth, and all these makes that the problem of fertilization of cotton is complicated more.
Summary of the invention
Technical problem to be solved by this invention is: in process of growth all kinds of nutritive elements are required different characteristics at the deficiencies in the prior art and cotton, a kind of quick-acting cotton formula fertilizer that cooperates with slowly-releasing is provided, this fertilizer is disposable employed can to guarantee substantially that cotton nourishes and grows in life and needed macroelement of reproductive growth and trace element, is a kind of safe, efficient, easy to use, environmentally friendly cotton formula fertilizer.
Its technical scheme is: a kind of quick-acting cotton formula fertilizers that cooperate with slowly-releasing, it is characterized in that: it is respectively by element N, P
