Problems solved by technology

However, according to the "Technical Regulations for Corn-Soybean Strip Compound Planting" (NY/T2632-2014) promulgated by the Ministry of Agriculture in recent years, there are two main problems: 1. The existing corn-soybean interplanting mode does not match the current planting system in Sichuan
Rapeseed can only be used for net cropping, and it is difficult to achieve intercropping of corn and soybeans due to seasonal restrictions after

Example Embodiment

[0055] Example 1 Screening of different fresh food species

[0056] After rapeseed harvest, fresh corn and fresh soybeans are intercropped. The corn variety is semi-compact corn variety Zhenghong 505, and the fresh soybean varieties are shown in Table 1.

[0057] On April 28, use a seedling tray to grow corn seedlings, with two seeds per hole, and transplant them when they grow to two leaves and one heart. On May 5th, after the rape harvest, corn transplanting and fresh soybean intercropping were carried out. One area (two rows) of corn intercropping and another area (two rows) of soybeans were planted. The distance between the corn belt and the belt is 160cm, the row spacing of corn in the belt is 40cm, and two adjacent rows of corn are transplanted in staggered holes, 2 plants per hole, 35cm hole spacing, and seedlings at the 3-leaf stage. Plant a zone (two rows) of fresh soybeans between the two corn belts, the distance between the fresh soybean belt and the corn belt is 60cm, ...

Example Embodiment

[0065] Example 2 Intercropping of fresh corn and fresh soybean

[0066] 1) Test subjects: The corn variety is a compact fresh corn variety Zhengtian 68, and the fresh soybean variety is a mid-maturing variety Zhexiandou 4.

[0067] 2) Test area: Yucheng District, Ya'an City, Sichuan Province

[0068] 3) Test method

[0069] On April 28, use a seedling tray to grow corn seedlings, with two seeds per hole, and transplant them when they grow to three leaves and one heart. On May 5, after rapeseed harvest, corn transplanting and fresh soybean intercropping were carried out, one area (two rows) of corn intercropping and another area (two rows) of fresh soybeans were planted. The distance between the corn belt and the belt is 180cm, the row spacing of corn in the belt is 50cm, and two adjacent rows of corn are transplanted in staggered holes, with 2 plants in each hole, and the hole spacing is 45cm. Plant a zone (two rows) of fresh soybeans between the two corn belts, the distance between...

Example Embodiment

[0077] Example 3 Intercropping of common corn and fresh soybean

[0078] 1) Test subjects: the corn variety is the semi-compact variety Zhenghong 505, and the fresh soybean is the mid-mature variety Zhexiandou 8.

[0079] 2) Test area: Gucheng Village, Longmen Township, Lushan County, Ya'an City, Sichuan Province.

[0080] 3) Test method

[0081] On May 25, after the rape is harvested, intercropping with corn and fresh soybeans will be carried out, and corn will be intercropped in one area (two rows) and fresh soybeans will be planted in another area (two rows). The distance between the corn belt and the belt is 170cm, the row spacing of the corn in the belt is 45cm, and the two adjacent rows of corn are sowed in staggered holes, the hole spacing is 40cm, 3-4 seeds per hole, and 2 seedlings are fixed at the 3-leaf stage. Plant a zone (two rows) of fresh soybeans between the two corn belts, the distance between the fresh soybean belt and the corn belt is 65cm, the row spacing of the f...

Abstract

The invention relates to the field of agricultural planting, in particular to a cultivation method for corn and fresh edible soybean interplanting after rape harvesting. The cultivation method for corn and fresh edible soybean interplanting after rape harvesting is mainly suitable for one-year-two-harvest cultivation areas of southwest dry land in Sichuan, Chongqing, Guizhou and the like. The planting area of fresh edible soybeans can be enlarged, and popularization and development of fresh edible soybeans are promoted. By the adoption of the planting method, land, nutrient and light and heat resources can be sufficiently utilized, the land equivalence ratio can be improved, land output is increased, the one-year-two-harvest effect is achieved, and the purposes of improving the land economic output and increasing incomes of farmers are achieved. In addition, the planting area of fresh edible soybeans can be enlarged, economic benefits are increased, and the living quality of people is improved.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a cultivation method for intercropping fresh soybeans with rapeseed and corn. Background technique [0002] Corn and soybean intercropping has the advantages of making full use of natural resources such as land, light, and heat, increasing crop yield per unit area, and improving soil fertility. At present, my country is facing continuous increase in food consumption, year-by-year decrease in cultivated land area, increased land carrying capacity, and farmland Under the new situation where the ecological environment is deteriorating and sustainable agricultural development is facing major challenges, it has been listed as the main technology in Sichuan and the whole country, and it is recommended for large-scale application. However, according to the "Technical Regulations for Corn-Soybean Strip Compound Planting" (NY / T2632-2014) promulgated by the Ministry of Agriculture in re...
