CN104885672A - Deep and accurate application method of rice field fertilizer - Google Patents

Abstract

The invention discloses a deep and accurate application method of a rice field fertilizer. The deep and accurate application method comprises the following steps: carrying out granulation or pelleting treatment on fertilizer grains, and applying in a jetting or shooting-off manner; accurately determining an application direction: accurately determining the application direction and position through adjusting aligned position and angle of a jetting or shooting-off device; and accurately determining the application depth and the like. By virtue of the deep and accurate application method, rice field deep application and rice root application can be effectively realized; the fertilizer is intensively applied deeply and directionally, so that the volatilization loss and the runoff loss of the fertilizer are reduced, and the fertilizer utilization rate is greatly improved; and the quantitative, directional and depth-keeping accurate application is carried out so that the application amount of the fertilizer is greatly reduced.

Description

The accurate application process of rice field deep fertilizer

Technical field

The present invention relates to a kind of rice field Term Fertilization method.

Background technology

Term Fertilization position, existing rice field and use the degree of depth and be difficult to accurate control, affects growth and the output of crop.Need to be improved further.

Summary of the invention

The object of the present invention is to provide a kind of Term Fertilization position and use the accurate application process of rice field deep fertilizer that the degree of depth can accurately control.

Technical solution of the present invention is:

The accurate application process of a kind of rice field deep fertilizer, is characterized in that: comprise the following steps:

(1) fertiliser granulates or pelletized process, injection or ejection type are used: used fertilizer is carried out granulating or pelletized process, or select granulating or pelletized fertilizer, under rice field no water layer or thin water layer situation, particle or pill fertilizer are passed through to spray or ejector, aim at paddy soils face to carry out spraying or launching, buried by the active force sprayed or launch; During operation, 10 ~ 50 centimetres, fertilizer nozzle distance ground;

(2) apply fertilizer precisely the determining of direction: by adjustment is sprayed or ejector is aimed at position and angle, accurately determine fertilising direction and position;

(3) precisely the determining of fertilization depth: by the particle of fertilizer or pellet sizes and the hard softness of paddy soil two indexs, calculate fertilizer soil-entering resistance; Require and fertilizer soil-entering resistance that according to fertilization depth the distance of the mouth that buries apart from fertilizer in conjunction with fertilizer nozzle regulates fertilizer to spray or ejection power, thus guarantees the exact depth that fertilizer buries.

Advantage of the present invention: one is effectively to realize Deep layer of rice field fertilising and rice strain rhizosphere fertilization, and fertilizer is used by deep layer and the concentrated of orientation, decreases waving of fertilizer and loses loss and Loss in Runoff, improve utilization rate of fertilizer significantly; Two is no matter be chemical fertilizer or fertilizer or crops straw etc., only by granulating or pelletized process, all can need use; Three are precisely used by quantitative, directed, depthkeeping " three is fixed ", realize rate of fertilizer and significantly reduce.

Below in conjunction with embodiment, the invention will be further described.

Embodiment

The accurate application process of a kind of rice field deep fertilizer, is characterized in that: comprise the following steps:

(1) fertiliser granulates or pelletized process, injection or ejection type are used: used fertilizer is carried out granulating or pelletized process, or select granulating or pelletized fertilizer, under rice field no water layer or thin water layer situation, particle or pill fertilizer are passed through to spray or ejector, aim at paddy soils face to carry out spraying or launching, buried by the active force sprayed or launch; During operation, 10 ~ 50 centimetres, fertilizer nozzle distance ground;

(2) apply fertilizer precisely the determining of direction: by adjustment is sprayed or ejector is aimed at position and angle, accurately determine fertilising direction and position;

(3) precisely the determining of fertilization depth: by the particle of fertilizer or pellet sizes and the hard softness of paddy soil two indexs, calculate fertilizer soil-entering resistance; Require and fertilizer soil-entering resistance that according to fertilization depth the distance of the mouth that buries apart from fertilizer in conjunction with fertilizer nozzle regulates fertilizer to spray or ejection power, thus guarantees the exact depth that fertilizer buries.

In addition, according to the fertile requirement of the need of paddy growth, in conjunction with the fertilizer absorption rate of From The Rhizosphere of Rice and the available nutrient content of institute's applying fertilizer, the accurate dosage of institute's applying fertilizer can be determined.

Claims (1)

1. the accurate application process of rice field deep fertilizer, is characterized in that: comprise the following steps:

(1) fertiliser granulates or pelletized process, injection or ejection type are used: used fertilizer is carried out granulating or pelletized process, or select granulating or pelletized fertilizer, under rice field no water layer or thin water layer situation, particle or pill fertilizer are passed through to spray or ejector, aim at paddy soils face to carry out spraying or launching, buried by the active force sprayed or launch; During operation, 10 ~ 50 centimetres, fertilizer nozzle distance ground;

(2) apply fertilizer precisely the determining of direction: by adjustment is sprayed or ejector is aimed at position and angle, accurately determine fertilising direction and position;

(3) precisely the determining of fertilization depth: by the particle of fertilizer or pellet sizes and the hard softness of paddy soil two indexs, calculate fertilizer soil-entering resistance; Require and fertilizer soil-entering resistance that according to fertilization depth the distance of the mouth that buries apart from fertilizer in conjunction with fertilizer nozzle regulates fertilizer to spray or ejection power, thus guarantees the exact depth that fertilizer buries.
