A kind of water-saving cultivation method of wheat

Abstract

The invention discloses a water-saving cultivation method for wheat, which comprises the following steps: 1) Moisture creation: perform irrigation and moisture creation before site preparation, so that the relative water content of the field soil reaches 70%-80%; 2) Set up furrows in the field, The length of the furrow is 7.5-10m, the width of the furrow is 4.6-4.8m, and the width of the furrow is 35-40cm; 3) Wheat is planted in the furrow, the sowing time of wheat is October 7-16 every year, and the sowing rate is 11-14kg / mu; 4) No irrigation in winter after planting of wheat, until the internodes at the base of wheat grow 1-2cm in the spring of the following year, flood irrigation is carried out in the border, and the irrigation amount is 50-60m3 / mu; when the relative water content of the soil during the flowering period of wheat is lower than 65%, Carry out flood irrigation in the border, and the irrigation amount is 40-50m3 / mu; 5) Harvest after 235-244 days of wheat planting. The method can improve the water use efficiency of wheat without reducing yield or slightly increasing yield, and realizes water saving, high yield and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of wheat cultivation, and in particular relates to a water-saving cultivation method for wheat. Background technique [0002] The Huanghuaihai region is the main wheat producing area in China, with a wheat planting area of ​​over 200 million mu and a total output of over 100 million tons. The annual precipitation in most parts of the region is 500mm-700mm, and it is mainly concentrated in summer. During the wheat growth period, the precipitation cannot meet the needs of wheat growth and development. Only through supplementary irrigation can high and stable yields be achieved. [0003] At present, the current irrigation system in this area is usually based on the premise of meeting the water demand of wheat in each growth period. Therefore, it is often seen in production that many times a large amount of water is irrigated during the wheat growth period. Moreover, the water use efficiency is low, which has c...

[0003] At present, the current irrigation system in this area is usually based on the premise of meeting the water demand of wheat in each growth period. Therefore, it is often seen in production that many times a large amount of water is irrigated during the wheat growth period. Moreover, the water use efficiency is low, which has caused serious ecological problems; in addition, the number of irrigations is high, the amount of irrigation water is large, and the soil water is not fully utilized, which leads to runoff of rainwater in summer and leakage to the ground, resulting in waste of water resources and at the same time causing The leaching of soil nitrate nitrogen pollutes groundwater and the environment; moreover, repeated irrigation increases costs and directly affects farmers and agricultural economic benefits

[0004] Spring wheat fertilizer and water management is an important link for high and stable yields. In current wheat production, many farmers do not take wheat growth characteristics and population quality as the basis. Many farmers take the Spring Festival as the time node and are eager to go out to work, resulting in premature spring irrigation and increased Population in spring, increasing the risk of late lodging, and wasting water
