Embodiment 1

[0019] An intercropping and planting method for returning all corn and soybean stalks to the field includes the following operation steps:

[0020] (1) The corn-soybean intercropping ratio is 8:8 for planting. The corn-soybean planting belts are interchanged in the next year, and the cropping is carried out in a two-year cycle. The corn planting density is 75,000 plants / ha and the soybean planting density is 220,000 plants / Hectares, the intercropping ratio of 8:8 means that a field is first planted with 8 rows of corn, then 8 rows of soybeans are planted next to each other, and then 8 rows of maize are planted next, and 8 rows of soybeans are planted next to each other; according to this method, planting by analogy;

[0021] (2) After the corn enters the harvest period, use a large-scale corn combine harvester to harvest, and at the same time crush the corn stalks into small sections with a length of 8 cm, and evenly disperse them in the field, and then spray the stalk rot evenly o...

Embodiment 2

[0026] An intercropping and planting method for returning all corn and soybean stalks to the field includes the following operation steps:

[0027] (1) The corn and soybean intercropping ratio is 8:8 for planting. The corn and soybean planting belts will be exchanged in the next year, and the cropping will be carried out in a two-year cycle. The corn planting density is 80,000 plants / ha and the soybean planting density is 230,000 plants / ha. Hectares, the intercropping ratio of 8:8 means that one farmland first planted 8 rows of corn, then planted 8 rows of soybeans next to each other, and then continued to plant 8 rows of corn, next to 8 rows of soybeans; according to this method, planting by analogy;

[0028] (2) After the corn enters the harvest period, use a large-scale corn combine harvester to harvest, and at the same time crush the corn stalks into small sections with a length of 10 cm, and evenly disperse them in the field, and then spray the stalk rot evenly on the surface o...

Embodiment 3

[0033] An intercropping planting method in which all corn and soybean stalks are returned to the field includes the following operation steps:

[0034] (1) The corn and soybean intercropping ratio is 8:8 for planting. The corn and soybean planting belts will be interchanged in the next year, and the cropping will be carried out in a two-year cycle. The corn planting density is 85,000 plants / ha and the soybean planting density is 240,000 plants / ha. Hectares, the intercropping ratio of 8:8 means that a field is first planted with 8 rows of corn, then 8 rows of soybeans are planted next to each other, and then 8 rows of maize are planted next, and 8 rows of soybeans are planted next to each other; according to this method, planting by analogy;

[0035] (2) After the corn enters the harvest period, use a large-scale corn combine harvester to harvest, and at the same time crush the corn stalks into 13 cm long sections, and evenly disperse them in the field, and then spray the stalk rot e...

Abstract

The invention discloses an intercropping and rotation planting method with complete field return of corn and soybean stalks, comprising the steps of (1), carrying out planting according to a corn andsoybean intercropping proportion of 8:8, interchanging corn and soybean planting belts in next year and carrying out crop rotation in a period of two years; (2), smashing corn stalks to obtain small sections, and uniformly spraying stalk decomposition agents to the surfaces of the smashed corn stalks; (3), deeply turning the corn stalks into soil layers at the depths of 25-30 cm, and then carryingout harrowing operation; (4), flatly sowing soybean seeds through no-tillage fertilizer applying and seed sowing machines in the next spring, applying fertilizers to the soybean seeds through the no-tillage fertilizer applying and seed sowing machines in the next spring and carrying out big-ridge twin-row planting; (5), omitting mechanical plowing operation after soybeans are harvested, carryingout large-ridge twin-row planting on corn through no-tillage technologies in the next spring, flatly sowing corn seeds by the no-tillage fertilizer applying and seed sowing machines, and applying fertilizers to the corn seeds through the no-tillage fertilizer applying and seed sowing machines. The method provided herein has the advantages that operating is simple, and the method is low in cost andis environmentally friendly, and the corn and soybean yields can be effectively increased.

Description

Technical field [0001] The technical field of crop planting of the present invention specifically relates to an intercropping planting method in which all corn and soybean stalks are returned to the field. Background technique [0002] The Northeast region is an important base for soybean production in my country. The total soybean output accounts for more than 40% of the country, which plays a pivotal role in my country's soybean production and demand. China's soybean imports reached 95.53 million tons in 2017, and the soybean production gap is very serious. The state clearly requires the increase of soybean planting area, the promotion of corn and soybean rotation technology, the reduction of fertilizers and pesticides, the establishment of a land use model that combines use and nutrition, and promotes sustainable agricultural development and food security. Intercropping corn and soybean can not only effectively use resources such as land, temperature and water, but also regul...
