Peanut and maize intercropping planting method

Abstract

The invention belongs to the technical field of crop planting, and particularly relates to a peanut and maize intercropping planting method. The peanut and maize intercropping planting method comprises the following steps that A, maize and peanut grains which are full in granule are finely selected to serve as seeds, and the maize seeds and the peanut seeds are soaked before planting; B, planted land is subject to deep ploughing and thorough harrowing before planting; C, during planting, two lines of maize is planted between five lines of peanut, wherein maize cavities and peanut cavities are staggered; D, straw ash and cow manure are spread into the cavities where peanut is subject to bunch planting, cow manure spread into the cavities where maize is subject to bunch planting, and then the peanut seeds and the maize seeds in the cavities are covered with soil beside the cavities; E, when peanut seedlings and maize seedlings are 15 cm to 25 cm, screening and seedling preserving treatment is carried out; F, first-time weeding and fertilization are carried out at the tenth to twentieth days after screening and seedling preserving, and second-time weeding and fertilization are carried out at the fifty five to sixty five day after first-time weeding and fertilization; and G, after second-time weeding and fertilization, when flower yellow leaves occur on the peanut, harvesting can be carried out, and harvesting is carried out after maize bracts are dry and white.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and specifically refers to a peanut-corn intercropping planting method. Background technique [0002] The per capita arable land area in my country is far below the world average level. How to increase the production and income of crops on limited land is a major problem facing our country. Corn is an annual herbaceous plant with taller plants. It is a temperature-loving crop. The whole growth period requires a higher temperature and can bloom and bear fruit under short-day conditions. Peanut is an annual herb that likes temperature, light and drought. It is a short-day crop. Crops, with relatively short plants, have strong nitrogen fixation ability, and have a certain self-regulation ability in the weak light environment under intercropping and shading conditions; for the cultivation of peanuts and corn, at present, my country generally adopts a single planting mode, and intercropping plant...

Problems solved by technology

Corn is an annual herbaceous plant with taller plants. It is a temperature-loving crop. The whole growth period requires a higher temperature and can bloom and bear fruit under short-day conditions. Peanut is an annual herb that likes temperature, light and drought. It is a short-day crop. Crops, with relatively short plants, have strong nitrogen fixation ability, and have a certain self-regulation ability in the weak light environment under intercropping and shading conditions; for the cultivation of peanuts and corn, at present, my country generally adopts a single planting mode, and intercropping planting is a A planting method that can intensively utilize natural resources such as light, heat, water, and fertilizer. The existing intercropping of corn and peanuts cannot increase production and income through intensive use of light and heat resources due to the unreasonable row and plant spacing. Purpose
