Crop rotation cultivation method for Winter rapes and Sweet-Waxy corn

Abstract

The invention belongs to the technical field of crop cultivation, and in particular relates to a crop rotation cultivation method for Winter rapes and Sweet-Waxy corn. The crop rotation cultivation method for the Winter rapes and the Sweet-Waxy corn comprises the following steps: step 1, preparing land and performing fertilization; step 2, planting the Winter rapes; step 3, performing management on the Winter rapes; step 4, planting the Sweet-Waxy corn: after the Winter rapes are harvested, planting the Sweet-Waxy corn in the middle and late June in a current year, before the Sweet-Waxy corn is planted, performing deep ploughing and soil drying on land, applying an organic fertilizer and a compound fertilizer, performing ridging, and performing mulching, wherein all operation is performedaccording to operation requirements of a technology of whole plastic-film mulching on double ridges and planting in furrows, and a planting density is 4500-4700 /mu; and step 5, performing managementon the Sweet-Waxy corn. The method provided by the invention makes full use of land resources, prevents waste of the resources, reasonably uses pesticides, and prevents environmental pollution; the method can ensure soil fertility, and a mulching film can guarantee a soil moisture content; and the method greatly improves a yield of the Winter rapes and the Sweet-Waxy corn, thereby improving economic income, and having great market application and promotion value.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for cultivating winter rapeseed and sweet waxy corn in rotation. Background technique [0002] In the same field, there is a planting method in which different crops or multiple crop combinations are planted sequentially between seasons or years. Crop rotation is a biological measure that combines land use and land cultivation. Leisure crop rotation was practiced in China as early as the Western Han Dynasty. In the "Qi Min Yao Shu" of the Northern Wei Dynasty, there are "Grain fields must be old and easy", "If you want to get good land, you don't need the old market", "In all valley fields, mung bean and small bean bottoms are the top, hemp, millet, and old hemp are second, turnips, "Soybean is the next" and other records have pointed out the necessity of crop rotation and described the sequence of crop rotation at that time. For a long time, China's drylands...
