specific Embodiment approach 1

[0044] Specific embodiment one: a kind of planting method of corn and cover crop in this embodiment is carried out according to the following steps:

[0045] 1. Land preparation in spring:

[0046] According to local agricultural production habits, spring soil preparation, rotary tillage or deep plowing should be carried out when the soil temperature meets the requirements;

[0047] 2. Ridging and base fertilizer application:

[0048] After soil preparation, carry out mechanical ridging, the ridge width is 130cm, the ridge height is 15-25cm, fertilization is applied, and the fertilizer application is the same as the local production field;

[0049] 3. Sowing corn:

[0050] Machine sowing or artificial on-demand sowing is adopted. The corn planting density is the same as the local production field. Two rows of corn are sown on the ridge, and the distance between the two rows of corn is 50cm, and the middle position of the two rows of corn is located on the center line of the ...

specific Embodiment approach 2

[0063] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the leguminous cover crop (lower in plant height) selected by D1 in step 4 is white clover. Others are the same as the first embodiment.

specific Embodiment approach 3

[0064] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the leguminous cover crop selected in D2 and D3 in step 4 is velvet. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for planting corn and cover crops, belongs to the field of crop planting, and particularly relates to a cultivating method of inter-annual crop rotation of corn and the cover crops. The technical problems of reduction of soil quality and non-point source pollution caused by large-scale use of chemical fertilizers, pesticides and herbicides in the corn planting process are solved. The cultivating method comprises the steps of 1, soil preparation in spring, 2, ridging and basal dressing, 3, sowing of corn, 4, sowing of the cover crops on ridges, 5, planting of the cover crops in furrows, 6, harvest of corn, 7, crushing of residual bodies of the cover crops and plowing in the spring of a next year, 8, ridging in the next year, and 9, field management in a second year. The cover crops such as gramineae are planted in the furrows, so that the field space is fully used, and the growth of weeds is avoided. The cover crops such as gramineae are planted in the furrows the biological yield is high, the absorption and utilization capacity for N in deeper layers of soil are good, and the protection effect for water resources and ecological environment is good.

Description

technical field [0001] The invention belongs to the field of planting crops, and in particular relates to a cultivation method for interannual rotation of corn and cover crops. Background technique [0002] Northeast my country has four distinct seasons, with rain and heat in the same season. Spring is dry and windy, summer is hot and rainy, autumn is crisp and clear, and winter is long and cold. Suitable crops are crops that ripen once a year, such as corn. Corn is an important food-feed-economic crop in my country, and occupies an important position in food production. Northeast China is the main corn producing area in our country, with a large area of ​​corn planting, and it is an important commercial grain base in our country. It has made an important contribution to ensuring my country's food security. However, due to the excessive pursuit of corn production, the extensive use of chemical fertilizers, pesticides, and herbicides in the corn planting process has cause...
