Method for planting wheat by utilizing straw substrate fertilizer

Abstract

The invention belongs to a crop planting technology and relates to a method for planting wheat by utilizing a straw substrate fertilizer. The method comprises the steps as follows: a, before sowing the wheat, taking the straw substrate fertilizer as a substrate fertilizer for treating soil, wherein 720-760 kg of the straw substrate fertilizer is used in 1 mu of the soil (1 mu is 1/6 of acre), and the straw substrate fertilizer is an organic fertilizer prepared by rotting and fermenting crop straws; b, sowing the wheat on November 10th to 15th along the middle and lower reaches of Changjiang River, wherein 12-14 kg of the wheat is sowed in 1 mu of the soil; and adding a nitrogen fertilizer twice in the crop growth process during the fourth leaf period and the second leaf period, wherein the addition amount of the nitrogen fertilizer is 20 kg of urea in 1 mu of the soil; and c, carrying out routine field management until crop harvesting. The method has the advantages as follows: 1, the straw substrate fertilizer is taken as a basic fertilizer, so that under the same nitrogen amount, the wheat growth is facilitated and the wheat yield is remarkably increased; and 2, the straw substrate fertilizer is continuously applied for multiple years, so that the soil structure is improved, the soil fertility level is increased, the usage amount of the nitrogen fertilizer can be properly reduced in the later period, and the cost is reduced.

Description

technical field [0001] The invention belongs to crop planting technology, and relates to a wheat planting method using straw matrix fertilizer. Background technique [0002] At present, in the cultivation of wheat in the middle and lower reaches of the Yangtze River, inorganic compound fertilizers are usually used as substrate fertilizers, and nitrogen fertilizers such as urea are used as topdressing fertilizers during crop growth. After years of production, soil fertility and crop yields will decrease, which is not conducive to The stable maintenance and improvement of production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wheat planting method using straw matrix fertilizer which can improve soil structure, improve soil fertility level and increase rice crop yield. [0004] The wheat planting method that adopts straw matrix fertilizer of the present invention is: [0005] a. The application of matrix fe...
