Embodiment 1

[0058] Embodiment 1 Demonstration of the corn-soybean strip intercropping planting method provided by the present invention

[0059] Test site: Fangcheng County, Henan Province.

[0060] Corn and soybeans were sown in early May 2012, and the second operation was carried out by using two rows of single openers with an interval of 60 cm and a reverse interval of 40 cm. Plant two rows of soybeans at intervals between two rows of corn, the row spacing between the two rows of corn is 40cm, the row spacing between the two rows of soybeans is 40cm, and the distance between the rows of corn and soybeans is 60cm. The distance between holes is 14cm, 1 grain per hole, and the number of falling seeds is 7 grains / m. The hole distance of the soybean seed meter of the planter is 8cm, 1 grain per hole, and the number of falling seeds is 8 grains / m. After sowing, the corn density is 4,700 plants / mu, and the soybean density is 8,000 plants / mu. The mechanized sowing operation method is as follo...

[0064] Embodiment 2 Demonstration of the corn-soybean strip intercropping planting method provided by the present invention

[0065] Test site: Chongming County, Yunnan Province.

[0066] Corn and soybeans were sown in May 2012. Two rows of single openers were used, with an interval of 60 cm and a reverse interval of 30 cm for the second operation. Plant two rows of soybeans at intervals between two rows of corn, the row spacing between the two rows of corn is 30cm, the row spacing between the two rows of soybeans is 30cm, and the distance between the rows of corn and soybeans is 60cm. The hole distance is 16cm, 1 grain per hole, the hole distance of the soybean seed meter of the planter is 5cm, 1 grain per hole. After sowing, the density of corn is 4625 plants / mu, and the density of soybean is 14700 plants / mu. A corn monocrop control group and a soybean monocrop control group were set up. Both the corn monocrop control group and the soybean monocrop control group were monoc...

Embodiment 3

[0070] Embodiment 3 Demonstration of the corn-soybean strip intercropping planting method provided by the present invention

[0071] Test location: Yuncheng County, Shandong Province.

[0072] Corn and soybeans were sown in May 2012. Two rows of openers were used to sow seeds in one row and soybeans in the other row. Plant two rows of soybeans at intervals between two rows of corn, the row spacing between the two rows of corn is 40cm, the row spacing between the two rows of soybeans is 40cm, and the distance between the rows of corn and soybeans is 70cm. The hole distance is 17cm, 1 grain per hole, the hole distance of the soybean seed meter of the planter is 8cm, 1 grain per hole. After sowing, the corn density is 3544 plants / mu, and the soybean density is 8060 plants / mu. A corn monocrop control group and a soybean monocrop control group were set up. Both the corn monocrop control group and the soybean monocrop control group were monocultured with local traditional planting...

Abstract

The invention provides a planting method for corn-soybean strip intercropping. The planting method includes the steps that corns and soybeans are seeded simultaneously, wide and narrow row spacing planting is adopted for the corns, the wide row line spacing of the corns is 140-190cm, the narrow row line spacing of the corns is 30-50cm, and planting density of the corns is 3500-4700 plants / mu. Two rows of soybeans are planted in a wide row of the corns, the row line spacing in a strip of the soybeans is 30-50cm, and the planting density of the soybeans is 8000-15000 plants / mu. The planting method can achieve the double high yield of the corns and the soybeans, and meanwhile can improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a corn-soybean strip intercropping planting method. Background technique [0002] Corn has become the largest food crop in my country and the food crop with the highest total output in the world. Maize has a large sowing area and a wide distribution in my country, and it is the crop with the largest area and yield potential among dryland grain crops. In addition to food, corn is also widely used in the fields of feed and industrial raw materials, such as the production of livestock feed, papermaking, brewing of shochu, and production of industrial alcohol. Due to the outstanding advantages of corn in many aspects, its demand is increasing year by year. [0003] Soybean is also an important crop in my country. It integrates food crops, economic crops, feed and processing raw materials, and has the longest processing chain. Soybean is rich in protein, fat and a var...
