Embodiment 1

[0020] This example was carried out in Xinhua Village, Quhe Township, Shehong County, Sichuan Province, China. During the horn-mouth stage of corn, the effects of different fertilization distances on the yield of corn and soybean were studied by adjusting the fertilization points (0, 15, 30, 45 cm) between the rows of corn and soybean.

[0021] The planting specifications of corn and soybeans are planted in wide and narrow rows. The wide row of corn is 160 cm, and the narrow row is 40 cm. When sowing soybeans, 2 rows of soybeans are planted in the wide row of corn. The corn variety is Xianyu 508, with a hole distance of 19 cm, a single plant in the hole, with a density of 3,500 plants / mu, and was sown on April 12; the soybean variety is Nandou 12, with a hole distance of 19 cm, and double plants in the hole, with a density of 7,000 Plant / mu, sowed on June 15. The primary fertilizer, that is, the base fertilizer of corn, is applied according to the conventional dosage, and 6 k...

Embodiment 2

[0025] Embodiment 2: the impact of different nitrogen content on the yield of corn and soybean

[0026] This example was carried out in Xinhua Village, Quhe Township, Shehong County, Sichuan Province, China. During the horn-mouth period of corn, the integrated fertilization method of corn-soybean intercropping (fertilization at a distance of 30 cm from the corn in the wide corn row) was used to study the effects of different nitrogen fertilizers on the yield of corn and soybean.

[0027]The planting specifications of corn and soybeans are planted in wide and narrow rows. The wide row of corn is 160 cm, and the narrow row is 40 cm. When sowing soybeans, 2 rows of soybeans are planted in the wide row of corn. The corn variety is Xianyu 508, with a hole distance of 19 cm, a single plant in the hole, with a density of 3,500 plants / mu, and was sown on April 8; the soybean variety is Nandou 12, with a hole distance of 19 cm, and double plants in the hole, with a density of 7,000 Pl...

Embodiment 3

[0031] Example 3: Effects of Different Fertilization Methods on Corn and Soybean Yield

[0032] This example was carried out in Tashui Village, Zhujia Township, Renshou County, Sichuan Province, China. To study the effects of traditional hole fertilization and integrated fertilization on the yield of corn and soybean.

[0033] The traditional fertilization treatment of corn is hole application, and the dosage is 6 kg of pure nitrogen per mu of base fertilizer, P 2 o 5 7.5 kg, K 2 O 7.5 kg, topdressing 8 kg of pure nitrogen per acre during the big bell mouth period of corn; applying 2 kg of pure nitrogen per acre of soybean base fertilizer, P 2 o 5 4 kg, K 2 O 4 kg, topdressing 2 kg of pure nitrogen per acre during the initial flowering stage. Corn-soybean integrated fertilization treatment is one-time fertilizer hole application, and the dosage is 6 kg of pure nitrogen per mu, P 2 o 5 7.5 kg, K 2 O 7.5 kg, during the big trumpet-mouth period of corn, the second fertil...

Abstract

The invention belongs to the technical field of crop culture and discloses an integral fertilization method for corn and soybean relay intercropping. The integral fertilization method for corn and soybean relay intercropping provided by the invention comprises the following steps that: corns and soybeans adopt wide and narrow line planting, the corns are seeded from the late March to the early April in each year, and the soybeans are seeded in the early and mid June in each year; and the primary fertilization is carried out during the corn seeding, and then, the secondary fertilization is carried out in a position in the wide line of the corn with a distance being 15 to 30cm from the corn line in a corn large-horn period or in 7 to 10 days before the tasseling. The fertilization distance and the multi-nutrient matching are scientifically controlled, the three links: the corn additional fertilization, the soybean base fertilization and the soybean seeding are organically unified, the time space complementation utilization of the corns and the soybeans on the fertilizers is realized, the goal of fertilizing one season of corn fertilizers and utilizing the fertilizers by the corn and the soybean in two seasons is reached, the production cost is reduced, the yield of the corns and the soybeans and the utilization of the fertilizers are improved, and the income of farmers is increased.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to an integrated fertilization method for corn intercropping soybeans. Background technique [0002] The intercropping mode is to use the complementary advantages of different species in terms of spatial distribution and nutrient requirements, so that the intercropping system can more effectively use various growth factors (light, water, various nutrients, etc.) to obtain yield advantages. Intercropping plays an important role in promoting the sustainable development of agriculture, especially in the intercropping of gramineous crops and leguminous crops, the intercropping advantages of gramineous crops are very obvious, and the yield and nitrogen uptake are often much higher than those in monocropping conditions . In the intercropping system, nitrogen transfer is the main promotion mechanism of nitrogen nutrition. Previous studies have found that there is a tw...
