Problems solved by technology

In the past, intercropping technology was mostly intercropping or intercropping single mode. Intercropping can make full use of space, but often ignores the problem of next stubble; intercropping can make full use of time, but sometimes it will cause a certain degree of waste in space

Embodiment 1

[0033] A planting method for interplanting no-tillage between corn, soybeans and potatoes, comprising the steps of:

[0034] Spring soybeans and corn are planted in wide and narrow rows, the narrow row spacing of corn is 40cm, the wide row spacing is 200cm, the plant spacing is 20cm, there are 3 rows of spring soybeans in the wide row, the spring soybean row spacing is 40cm, the plant spacing is 20cm, and there are 2 plants per hole; The variety is suitable for early sowing and mid-maturing spring soybean variety Guichun No. 8, and the corn is semi-compact Yidan 629; the spring soybean was sown on February 5, and the corn was sown on March 5. After sowing spring soybeans, use Jindur to seal them at 100mL / mu, and use Kangkuan to control soybeans and corn at 5mL / mu and 15mL / mu on March 25 and April 24 respectively. There are stinkbugs in the grain stage, and the stinkbugs are sprayed with conventional insecticides. When sowing soybeans, apply sufficient base fertilizer at 10kg / ...

Abstract

The invention belongs to the technical field of crop cultivation, and particularly relates to an interplanting and no-tillage planting method among corn, a soybean and a potato. The interplanting and no-tillage planting method among the corn, the soybean and the potato comprises the following steps of planting site selection, variety selection, planting mode selection, timely early sowing, paclobutrazol seed dressing, straw covering, weed prevention and control, pest control and nutrient and water management. According to the planting method, rotation of crops in different seasons are reasonably arranged, so that the planting time of the crops in the different seasons is more compact; collocation of leaf area index spaces of the crops is more reasonable; shading influences of long-stalked crops on short-stalked crops are reduced; an idle period of land is shortened; a multiple crop index of the land is increased; a yield per unit area is increased; a yield per unit land area is increased. The planting method realizes triple cropping under the condition that next-year rotation is not influenced.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a no-tillage planting method for interplanting corn, soybeans and potatoes. Background technique [0002] The southern region of our country is rich in light and heat resources, which has created rich natural resource conditions for the development of multi-cropping. However, due to crop planting arrangements and other reasons, stubble conflicts have resulted in large areas of winter fallow fields. Intercropping technology can improve land use efficiency and increase the output per unit area of ​​land. It is a high-efficiency, land-use and land-raising planting model, which provides technical support for the development of more than one year of cropping. The intercropping technology in the past is mostly intercropping or intercropping single mode, which can make full use of space during intercropping, but often ignores the problem of next stubble; intercroppi...
