Method for interplanting wheat in paddy field

Abstract

The invention discloses a method for interplanting wheat in a paddy field. The method includes the steps of firstly, preparing composite organic fertilizer; secondly, preprocessing seeds; thirdly, removing water before the harvest of paddy rice; fourthly, sowing wheat seeds; fifthly, harvesting the paddy rice; sixthly, spraying EM fermentation broth after the harvest of the paddy rice; seventhly, spreading the composite organic fertilizer 5-10 days after the EM fermentation broth is sprayed; eighthly, checking seedlings and filling gaps with seedlings; ninthly, managing fertilizer; and tenthly, carrying out weeding. The method has the advantages that the wheat is interplanted in the paddy field, so that high yield of the paddy rice and the wheat is achieved, and problems of conflict between rice straw field-returning and wheat sowing seasons and quality and the like are solved effectively; meanwhile, use amount of the organic fertilizer is reduced, and resource recycling is achieved; and the method is capable of reducing soil moisture loss, is ecological and environment friendly, is stable and high in yield, and is capable of modifying soil, saving cost and increasing yield. The main advantage of the method is that the yield of the wheat produced by using the method of the invention is increased by 8-12% as compared with that of the wheat produced by using a conventional planting method.

Description

technical field [0001] The invention relates to a planting method for interplanting wheat in paddy fields. Background technique [0002] my country's arable land resources are limited, and the per capita arable land accounts for less than half of the world's per capita arable land, but feeds a quarter of the world's population. In areas where rice and wheat are suitable for planting, it is of great significance to vigorously promote rice-wheat rotation to increase my country's grain production and ensure food security. However, rice-wheat rotation is affected by stubble, limited temperature and light resources, and difficulties in handling straw after rice harvest. Some areas suitable for rice-wheat planting have only grown rice for one season. By adopting the planting method, the rice-wheat rotation is realized, and the farmers' income is increased. In recent years, with the adjustment of the agricultural industrial structure, the transfer of a large number of rural labor...

[0004] Chinese patent CN201510258400.7 discloses a planting method of no-tillage and interplanting wheat in paddy fields. This patent adopts the method of interplanting wheat in paddy fields, planting wheat before harvesting rice, and then harvesting rice. The disadvantage is that the increase in yield is not very high
