Abstract

The invention relates to a novel wheat sowing technology. The novel technology comprises the following steps: ploughing a land by using a rotary cultivator as flat as possible; adjusting till each leg of a sowing machine is consistent and controlling the sowing depth at 1-2 centimeters; performing shallow seeding without suppression regardless of sandy soil, combined soil or clay; furrowing and performing middle-water irrigation, wherein wheat seedlings emerge before surface layer soil becomes dry, so that seedlings can emerge 15-20 days in advance, the sowing quantity can be saved by 7.5-10 kilograms per mu, the tiller number of each seed is increased by 3-4, spike formation of each plant is realized, and the yield can be increased by 30-50 percent. The emergence date of wheat is delayed, shallow seedling is unsuitable for dry farmlands and high-moisture farmlands, accumulated temperature before winter can be raised effectively, weak wheat seedlings can be turned into strong seedlings under the same management condition, and the spike number per mu and kernels per spike are increased effectively, so that the yield per mu is increased greatly.

Description

Wheat cultivation new technology

Technical field

The invention belongs to a kind of agrotechnique, concrete is by the emerge prolongation on date of wheat, increases effectively mu spike number, grain number per spike, thereby increases substantially the agrotechnique of per mu yield.

Background technology

North China is the main producing region of winter wheat, in planting season due to annual winter wheat, the temperature in the north is lower, soil moisture content is bad, affect the germination of winter wheat, divide evil, thereby affect the output of winter wheat, as as, annual 1-10 day in October, should be at 15-17 kg/acre, seeding quantity is advisable, the annual Gregorian calendar is after October 20, due to the emerge prolongation on date of wheat, dry land no matter, still there is moisture in the soil field, unsuitable upper seeding, can effectively increase accumulated temperature before the winter, make the wheat under same management condition become strong sprout by weak seedling, increase effectively mu spike number, grain number per spike, thereby the per mu yield of increasing substantially, according to local conditions, take upper seeding as core.

Summary of the invention

For the problems referred to above, the object of the invention is to propose a kind of wheat cultivation new technology.This method is utilized the emerge prolongation on date of wheat, and no matter dry land, still has moisture in the soil field, unsuitable upper seeding, can effectively increase accumulated temperature before the winter, makes wheat under same management condition by weak seedling change strong sprout, increase effectively mu spike number, grain number per spike, thereby increase substantially the advantage of per mu yield.

Wheat cultivation new technology, is characterized in that comprising the following steps: first, after soil being ploughed with suspend-tilling machine, with smooth for well; Secondly, should be consistent by the adjustment of every leg spacing of sower, sowing depth 1-2 centimetre is advisable; Secondly implement upper seeding, sowing depth is sandy loam no matter again, or two close soil, or clay, after planting without suppression; Then beat furrow, then carry out middle water irrigation, topsoil is not dry, and wheat is to emerge, and the 15-20 days of can emerging in advance like this, can save seeding quantity 15-20 jin for every mu, and every seed divides evil number to increase 3-4 strain, and strain strain Cheng Sui, and output can increase 3-5.

The present invention is without having ploughed behind soil, implement upper seeding, sowing depth is advisable with 2-3 centimetre, broadcast rear suppression well, take North China as example, 1-10 day in October, should be at 15-17 kg/acre, seeding quantity is advisable, the annual Gregorian calendar is after October 20, due to the emerge prolongation on date of wheat, dry land no matter, still there is moisture in the soil field, unsuitable upper seeding, can effectively increase accumulated temperature before the winter, make the wheat under same management condition become strong sprout by weak seedling, increase effectively mu spike number, grain number per spike, thereby the per mu yield of increasing substantially, according to local conditions, take upper seeding as core, (clay earth telogenesis is not tied and is covered sandy loam in irrigated land, two to close native top layer not dry) seedling to be to be unearthed, good conditions for soil moisture's, topsoil is not dry, wheat is to root, thereby reach strong sprout, the mu percentage of earbearing tiller increases, grain number per spike increases, and then raising per mu yield.

Embodiment

Below in conjunction with embodiment, the present invention is described further:

Embodiment: wheat cultivation new technology, is characterized in that comprising the following steps: first, after soil being ploughed with suspend-tilling machine, with smooth for well; Secondly, should be consistent by the adjustment of every leg spacing of sower, sowing depth 1-2 centimetre is advisable; Secondly implement upper seeding, sowing depth is sandy loam no matter again, or two close soil, or clay, after planting without suppression; Then beat furrow, then carry out middle water irrigation, topsoil is not dry, and wheat is to emerge, and the 15-20 days of can emerging in advance like this, can save seeding quantity 15-20 jin for every mu, and every seed divides evil number to increase 3-4 strain, and strain strain Cheng Sui, and output can increase 3-5.

Claims

1. a wheat cultivation new technology, is characterized in that comprising the following steps: first, after soil being ploughed with suspend-tilling machine, with smooth for well; Secondly, should be consistent by the adjustment of every leg spacing of sower, sowing depth 1-2 centimetre is advisable; Secondly implement upper seeding, sowing depth is sandy loam no matter again, or two close soil, or clay, after planting without suppression; Then beat furrow, then carry out middle water irrigation, topsoil is not dry, and wheat is to emerge, and the 15-20 days of can emerging in advance like this, can save seeding quantity 15-20 jin for every mu, and every seed divides evil number to increase 3-4 strain, and strain strain Cheng Sui, and output can increase 3-5.
