Cowpea and potato interplanting method

Abstract

The invention discloses a cowpea and potato interplanting method. The method comprises steps as follows: land preparation and fertilizer application: a ridged sowing bed for sowing of potatoes is opened, deep ditches are dug on two sides of the ridged sowing bed, high ridges for erecting a shed frame for cultivating cowpeas are formed beside the deep ditches, and the high ridges extend in the east-west direction; in early February, germination accelerating treatment is started to be performed on the potatoes, and the potatoes are sowed in the ridged sowing bed after spring comes and are harvested in June; in the middle ten days of June, the cowpeas are sown in the high ridges, the distance between every two cowpea plants is 20-25 cm, scaffold insertion and vine guiding are performed beforethe cowpeas put forth vines, bamboo scaffolds are obliquely inserted along the high ridges and firmly and crossly tied, and the intersections of the bamboo scaffolds are 1.4-1.6 m higher above the ground. By means of the method, the cowpeas and the potatoes can be planted simultaneously, the field area can be effectively utilized, space of subsoil is utilized, and upper space formed by the bambooscaffolds is effectively utilized for growth of the cowpeas.

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...
