Cowpea and potato interplanting method

Abstract

The invention discloses a method for interplanting cowpea and potato. The method comprises: fertilizing the soil, opening a bed for sowing potatoes, digging deep ditches on both sides of the bed, and setting up high scaffolding for cultivating cowpea next to the ditch. The ridges and high ridges are east-west; start germination treatment for potatoes at the beginning of February, sow them into the bed in spring, and harvest potatoes in June; sow cowpeas into high ridges in mid-June, with a distance of 20-25cm between cowpea plants. Before the vines are pulled out, the vines are inserted into the frame, and the bamboo frame is inserted obliquely along the high ridge direction, and crossed and fastened. The intersection of the bamboo frame is 1.4~1.6m away from the ground. The method of the invention can plant cowpea and potato at the same time, can effectively utilize the field area, not only utilizes the space of the lower soil, but also effectively utilizes the upper space formed by the bamboo frame for the growth of the cowpea.

Description

technical field [0001] The invention designs the field of crop cultivation, and in particular relates to a method for interplanting cowpea and potato. Background technique [0002] Both cowpea and potato are food that people usually love very much. When planting cowpea and potato, cowpea is an annual winding herbaceous plant. The tubers are cut into seed potatoes and planted in the ground for propagation. People only increase the yield of potatoes from the design of field borders and the cultivation of potato growth. The forms of producing potatoes and cowpeas are relatively simple, and the economic benefits of the same area of ​​​​field are not high. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a method of interplanting cowpea and potato that can effectively utilize the land area, which is improved based on field furrows and vertical frames, and is used to provide high-yield and high-quality potatoes and c...
