Method for planting winter-planted potatoes with rice as preceding crops

Abstract

The invention discloses a method for planting winter-planted potatoes with rice as preceding crops. The method comprises the following steps that preceding crop rice straw is smashed, the smashing length does not exceed 10 cm, the smashed preceding crop rice straw is evenly spread on the surface of field soil, and then the smashed preceding crop rice straw is turned into the soil during plowing; a base fertilizer is uniformly applied to the earth surface after plowing, and then soil blocks are raked into pieces, so that the base fertilizer is uniformly mixed in a soil layer; ditching application of a soil conditioner is performed or the soil conditioner is applied to the surface of the raked land, and then ridging and soil turning are carried out to concentrate the soil conditioner under the surface layer of the soil; dressing of an instant high-potassium ternary chemical compound fertilizer is carried out 45-50 days after sowing according to the growth vigor of the winter-planted potatoes; and the straw can be completely smashed to return to the field or 2 / 3 of the straw can be smashed to return to the field and 1 / 3 of the straw is used as covering. According to the method, through straw smashing for returning to the field and additional application of the soil conditioner, the growth environment of potatoes is improved, the organic matter content and nutrient content of soil are increased, the yield of the potatoes is increased, the quality of the potatoes is improved, resources are effectively utilized, and ecological environment protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of potato planting, in particular to a method for planting winter potatoes whose previous crop is rice. Background technique [0002] Soil is the key to crop growth and human food security, and the quality of soil is related to the quality and health of crops. In recent years, in order to increase land output and increase benefits, the "potato-rice-rice" three-cropping rotation mode not only increases crop yields, but also brings good economic benefits to farmers. However, long-term continuous cropping leads to soil fertility decline, especially On acidic soils, the extensive use of chemical fertilizers has aggravated the acidification of the soil, resulting in a decrease in the content of available nutrients and organic matter in the soil. At the same time, excessive chemical fertilizers have also brought many environmental and food health problems, and also caused input costs. increase and waste of resour...
