Abstract

The invention discloses a trace element composite foliar fertilizer for cotton, which comprises trace elements, aids and water, and is characterized in that: the content of trace elements (Zn+Mn+B+Mo+Cu+Fe) is 100 to 120g/L, the mass ratio of the Zn to Mn to B to Mo to Cu to Fe is (16-18):(8-9):(2.5-3):(1-1.5):(1-1.5):1, the content of a chelant is 10 to 20g/L, and the content of a wetting agent is 0.1 to 0.5g/L. The foliar fertilizer is diluted by 500 to 800 times with water, 50 to 100kg of the foliar fertilizer is used for each mu, and the foliar fertilizer is sprayed once in the flower bud period, primary flowering period and full blossom period of the cotton, and the yield of cotton seeds is improved by over 8 percent.

Description

The one special microelement composite foliage fertilizer that grows cotton

One, technical field

The present invention relates to a kind of chemical fertilizer, particularly polynary composite fertilizer with trace elements exactly, is the special microelement composite foliage fertilizer that grows cotton.

Two, background technology

In recent years, cotton increase in demand and cotton grower to increase income the contradiction that difficulty strengthens very outstanding.On the one hand, along with China's fabric clothing trade enters " back quota " epoch, export volume will continue to increase, and oil enters high price and causes weaving to improve with cotton ratio, consumption of pulling Cotton in China and the powerful of producing.Prediction according to experts' analysis, China's spinning increased more than 10% with cotton year, and raw cotton produces and need be in " tight balance " state.On the other hand, because global oil enters the high price epoch, prices of the means of agricultural production rises on the way.Improving per unit area yield, improve the production quality, increase peasant's benefit, is the important channel that keeps the Cotton Production sustainable and stable development.Follow high-yield cotton growth-development law applying fertilizer, fertilizer is used on " edge of a knife ",, increase economic efficiency to give full play to fertilizer efficiency.According to the growth and development characteristics of cotton, cotton can be adopted the fertilizer practice of " end two chases after ", promptly uses sufficient base manure, surely executes flower bud fertilizer, heavy dressing flower bell fertilizer.How the flower bud fertilizer of being executed, Hua Lingfei are based on trace element fertilizer, and for little fertilizer, liquid-type foliage-spray effect is best.

Three, summary of the invention

The present invention is intended to for cotton provides a kind of liquid-type trace element composite foliage fertilizer (being called for short foliage fertilizer down), and technical problem to be solved is multiple micronutrient element determination of ratio and the consistency in solution thereof.

The alleged micronutrient element of the present invention is meant zinc, manganese, boron, copper, molybdenum and iron, is selected from water miscible zinc sulfate, manganous sulfate, instant boron, copper sulfate, ammonium molybdate and ferrous sulfate, and its content is respectively in Zn, Mn, B, Cu, Mo, Fe.

This foliage fertilizer is to be the foliage fertilizer of solvent with water, comprise micronutrient element, auxiliary agent and water, difference with the prior art is trace element (Zn+Mn+B+Mo+Cu+Fe) content 100～120g/L, and its mass ratio is: Zn: Mn: B: Mo: Cu: Fe=(16～18): (8～9): (2.5～3): (1～1.5): (1～1.5): 1; Sequestrant content is 10～20g/L, wetting agent content 0.1～0.5g/L.Preferred trace element (Zn+Mn+B+Mo+Cu+Fe) is 105～115g/L, sequestrant content 15～20g/L; Wetting agent content 0.2～0.3g/L.

Selected sequestrant is selected from EDTA or quadrol or citric acid etc.Form inner complex with trace elements zn, Mn, Cu, Fe, thereby suppress insoluble borate and the generation of molybdate precipitation.

Described wetting agent is selected from anionic or nonionic surface active agent, as alkyl-sulphate, alkylsulfonate, lauroyl diethanolamine, coconut oil diethanolamine, fatty alcohol-polyoxyethylene ether etc.Its effect is the surface tension that reduces solution, improves solution in the blade face wettability of the surface, makes it even spread, prevents that pearl from falling, prolong solution residence time of blade surface to guarantee the abundant absorption of cotton to nutrient.

Described instant boron is four water eight borate two sodium (Na ₂B ₈O ₁₃4H ₂O), boracic 20.9% is a kind of new and effective instantly-soluble borate.

The preparation method of this foliage fertilizer is zinc, manganese, boron, copper, molybdenum and the iron material solution that obtains soluble in water with metering; The sequestrant that adds metering then in solution stirs 1～2h in 60～80 ℃; The wetting agent that adds metering again in the solution behind chelating stirs 0.5～1h in 40～60 ℃; Filter at last and be intended to remove the non-water soluble impurity of bringing in the raw material.

When using, converts this foliage fertilizer 500～800 times of water dilutions, mu diluent 50～100kg, and in cotton bud stage, initial bloom stage, each spray of full-bloom stage once, unginned cotton is on average increased production more than 8%.Spray in back 5 hours and rain, then should mend and execute as if meeting.

Four, embodiment
