Problems solved by technology

Nearly half of the arable land in our country is often threatened by drought. In the existing technology, multiple irrigations are used to alleviate the drought problem, and combined with sufficient fertilizer to achieve the purpose of high yield of wheat, but the more irrigation, the greater the fertilizer consumption and the more fertilization , the more water is consumed, so there is an urgent need for a reasonable water-saving and fertilizer-saving wheat cultivation method to achieve high yields of wheat while reducing production costs

Abstract

The invention discloses a water-saving high-yield cultivation method of wheat in dry land and belongs to the technical field of agricultural planting. The method includes the following steps of S1, applying 500-1,000 kg of decomposed farmyard manure, 15-18 kg of pure nitrogen in nitrogenous fertilizer, 12-15 kg of phosphorus pentoxide, 8-10 kg of potassium oxide, 0.5-1 kg of borax and 10-15 kg ofwater retention capsules to cultivation land per mu from late September to early October; applying 60-85 mm of soil moisture water before sowing of the wheat; S2, in mid-to-end October, adopting a mode of conducting strip cropping in a wide range for sowing; S3, conducting field management, wherein jointing water is applied from next middle March to next early April, and 4-8 kg of urea is supplemented in combination with the jointing water; S4, carrying out harvesting. By means of the cultivation method, through combined application of organic farmyard manure and chemical fertilizer, the waterretention capsules serve as micro water reservoirs to continuously supply water to the wheat, water and fertilizer are saved, the number of ears and ear grains is increased at the same time, and highyield is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a water-saving and high-yield cultivation method for dryland wheat. Background technique [0002] The average annual precipitation in the dry farming areas of northern my country is between 250-550mm, and the rainfall in most areas is concentrated in the three months of July, August and September each year, accounting for about 60%-70% of the total annual precipitation. The rainfall in China only accounts for 10%-15%, and the frequency of spring drought in the northern region is very high. In recent years, the annual rainfall in the northern region has a large variability. The continuous drought in summer and autumn, and the continuous drought in winter and spring are also very serious. Therefore, in the northern region, there are nine droughts in ten years, two droughts in three years, and minor droughts every year. Nearly half of the arable land in our country is o...
