Description

The method of northwestern, Anhui wheat dry-farming fertilising

Technical field:

The present invention relates to Anhui province proportion of crop planting method improvement technical field, be specifically related to the method for northwestern, Anhui wheat dry-farming fertilising.

Background technology:

Dry farming refers to the semiarid of non-irrigated condition and half moistening inclined nonirrigated farmland district, the main a kind of rainfed farming relying on natural rainfall to be engaged in agricultural production.Quite growing in one period, our agricultural research emphasis in irrigated land, and ignores the improvement to dryland farming yield-increasing technology relatively.This is because the effect of increasing production of irrigating is obvious.But along with the exploitation of water resource, the continuation of irrigated area expands close to the limit, and now, we must attach great importance to the improvement of nonirrigated farmland yield-increasing technology.

And for present working condition, though be which kind of plantation mode and plant which kind of product, apply fertilizer, management is all absolutely necessary link, no matter what implantation methods of many areas, as long as identical plantation product, the method of fertilising is all the same, product stunted growth, production declining, soil and environment will be caused like this to be destroyed, will bring serious loss like this.

Summary of the invention:

Technical problem to be solved by this invention is that overcoming existing technological deficiency provides a kind of method that method is reasonable, enforcement is convenient, northwestern, the Anhui wheat dry-farming of simple operation applies fertilizer.

Technical problem to be solved by this invention adopts following technical scheme to realize:

The method of northwestern, Anhui wheat dry-farming fertilising, is characterized in that: comprise following methods,

For advocating peace, method one, base fertilizer see that moisture in the soil is applied fertilizer: one of principal element of Dryland fertilizer effect is the supply of moisture, for precipitation and the characteristic distributions thereof of Dryland, adhere to fertilizer, nitrogenous fertilizer, phosphate fertilizer bottom application, N-dressed deeply, the principle executed concentrated by phosphate fertilizer, accomplishes N combination with P, and science is used;

Method two, extensively ward off the source of manure and applying organic manure: fertilizer mainly contains four sources, i.e. barnyard manure, stalk, green manure and refined organic fertilizers; Base oneself upon arid, the measure that " supporting ", " going back ", " kind " combine, " supporting " is exactly greatly develop aquaculture, increases the consumption of farmyard manure, continuous fertilizing soil, improves the production capacity in nonirrigated farmland; " going back " i.e. straw-returning, comprise Straw Crushed for Reclaiming and straw mulching and returning, in order to increase soil organic matter content, coordinating organic-inorganic ratio;

Method three, N combination with P and heavy dressing phosphate fertilizer: carry out balance corresponding fertilization, the movement of phosphorus in dryland soil and release are restricted, so nitrogen pick-up phosphorization, according to the regulation of fertilizer requirement of crop, the nutrient-supply capacity of soil, fertilizer use effect, in conjunction with the farming feature of dry farming, carry out " survey, join, produce, supply, execute " one package service;

Method four, use the fertilizer practice of plastic film mulching cultivation: the amount of application increasing fertilizer and nitrogen, phosphatization fertilizer, uses sufficient base fertilizer, topdress in time in conjunction with precipitation, compensating fertilizer;

Method five, the fertilizer practice using improving straw mulching to cultivate: improving straw mulching mainly divides wheat and maize two large class, the mode of covering has whole stalk lid and pulverizes lid, when improving straw mulching is cultivated, increase the amount ratio of nitrogenous fertilizer, increase by 1.35 times; And the field covered for many years, the consumption of fertilizer reduces 1/2 or do not execute.

Beneficial effect of the present invention is: very clear of above-mentioned method statement, and such staff is just very convenient in reference to above-mentioned method work, and is not easy to occur large error and error, this makes it possible to increase work efficiency.The inventive method is reasonable, enforcement is convenient, simple operation.

Embodiment:

The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below.

The method of northwestern, Anhui wheat dry-farming fertilising, is characterized in that: comprise following methods,

For advocating peace, method one, base fertilizer see that moisture in the soil is applied fertilizer: one of principal element of Dryland fertilizer effect is the supply of moisture, for precipitation and the characteristic distributions thereof of Dryland, adhere to fertilizer, nitrogenous fertilizer, phosphate fertilizer bottom application, N-dressed deeply, the principle executed concentrated by phosphate fertilizer, accomplishes N combination with P, and science is used;

Method two, extensively ward off the source of manure and applying organic manure: fertilizer mainly contains four sources, i.e. barnyard manure, stalk, green manure and refined organic fertilizers; Base oneself upon arid, the measure that " supporting ", " going back ", " kind " combine, " supporting " is exactly greatly develop aquaculture, increases the consumption of farmyard manure, continuous fertilizing soil, improves the production capacity in nonirrigated farmland; " going back " i.e. straw-returning, comprise Straw Crushed for Reclaiming and straw mulching and returning, in order to increase soil organic matter content, coordinating organic-inorganic ratio;

Method three, N combination with P and heavy dressing phosphate fertilizer: carry out balance corresponding fertilization, the movement of phosphorus in dryland soil and release are restricted, so nitrogen pick-up phosphorization, according to the regulation of fertilizer requirement of crop, the nutrient-supply capacity of soil, fertilizer use effect, in conjunction with the farming feature of dry farming, carry out " survey, join, produce, supply, execute " one package service;

Method four, use the fertilizer practice of plastic film mulching cultivation: the amount of application increasing fertilizer and nitrogen, phosphatization fertilizer, uses sufficient base fertilizer, topdress in time in conjunction with precipitation, compensating fertilizer;

Method five, the fertilizer practice using improving straw mulching to cultivate: improving straw mulching mainly divides wheat and maize two large class, the mode of covering has whole stalk lid and pulverizes lid, when improving straw mulching is cultivated, increase the amount ratio of nitrogenous fertilizer, increase by 1.35 times; And the field covered for many years, the consumption of fertilizer reduces 1/2 or do not execute.

More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
