example 1

[0011] 1) Before planting, apply basal fertilizer in the field and raise the ridge with a width of 45cm; the length shall be subject to the length of the field; the height shall be 10cm.

[0012] 2) Sow the sorghum in mid-May. Divide the ridge width into 3 equal parts, sow in 1 / 3 of the ridge width and 2cm in depth, water and fertilize in time, and strengthen field management.

[0013] 3) In mid-June, sow cowpeas at 1 / 3 of the distance from the sorghum, 2 grains per hole, and apply a small amount of urea or dilute manure to cover the soil for field management.

[0014] 4) After the cowpea seedlings are drawn and the vines are drawn, it will be carried out at 10 o'clock in the morning on a sunny day. The main vines are wound on the sorghum stalks in a clockwise direction on one ridge, and the main vines are wound on the sorghum stalks in a counterclockwise direction on two adjacent ridges. If there is any fall, use a plastic band to tie it gently. Do not use force. Remove the plastic ...

example 2

[0016] 1) Apply basal fertilizer to ridges in the field, the ridge width is 50cm; the length is subject to the field length; the height is 12cm.

[0017] 2) Sow the sorghum in mid-May. Divide the ridge width into 3 equal parts, sow in 1 / 3 of the ridge width and 3cm deep, water and fertilize in time, and strengthen field management.

[0018] 3) In mid-June, sow cowpeas at 1 / 3 of the distance from sorghum, 3 seeds per hole, apply a small amount of urea or dilute manure water to cover the soil for field management.

[0019] 4) After the cowpea seedlings are drawn and the vines are drawn, it will be carried out at 10 o'clock in the morning on a sunny day. The main vines are wound on the sorghum stalks in a clockwise direction on one ridge, and the main vines are wound on the sorghum stalks in a counterclockwise direction on two adjacent ridges. If there is any fall, use a plastic band to tie it gently. Do not use force. Remove the plastic band after the cowpea vine surrounds itself; remo...

Abstract

The invention relates to an interplanting method for sorghum and cowpea. According to the method, sorghum and cowpea are utilized for realizing the interplanting, the root nodule nitrogen fixation effect is utilized by the cowpea, the absorption on the nitrogen element is enhanced, sorghum straws provide support frames for the cowpea, and frame materials are saved. The method provided by the invention has the advantages that a novel ecological agriculture development mode is formed, in addition, double harvesting of the sorghum and the cowpea is realized, the land utilization rate is obviously enhanced, in addition, the operation of the method is simple and convenient, the implementation is easy, the economic benefits are obvious, and the method is suitable for being popularized and applied.

Description

Technical field [0001] The invention belongs to the technical field of crop planting, and specifically relates to a method for interplanting sorghum and cowpea. Background technique [0002] Interplanting refers to the planting method of planting between rows of crops in the early growth period or transplanting the crops after transplanting, also called intercropping and string cropping. Compared with single cropping, it can not only make full use of space in stages, but more importantly, it can extend the utilization of the growing season of crops in later seasons, increase the multiple crop index, and increase the total annual output. It is a planting method that uses time intensively. In my country, in the process of sorghum planting and production, a large area of ​​land is used to grow a single sorghum variety. The land utilization rate is low and the economic effect is poor. [0003] Long cowpea is one of the main high-protein legume vegetables in my country. The long cowp...
