Embodiment 1

[0019] Soybeans and corn are planted in wide and narrow rows, the narrow row spacing of corn is 0.45 meters, and the wide row spacing is 1.55 meters. Two rows of soybeans are planted inside, with a row spacing of 0.45 meters. Daily sowing, the selection of compact corn variety Chengdan 14 is conducive to high soybean yield and double crop yield of corn and soybean.

[0021]

Embodiment 2

[0023] The planting specifications of soybeans and corn are planted in wide and narrow rows. The wide row of corn is 1.55 meters, and the narrow row is 0.45 meters. When sowing soybeans, 2 rows of soybeans are planted in the wide row of corn. The corn variety is compact Chuandan 418, and the soybean variety is late-maturing Gongxuan No. 1. Sowing in early June is conducive to high soybean yield.

Embodiment 3

[0027] The planting specifications of soybeans and corn are planted in wide and narrow rows. The wide row of corn is 1.55 meters, and the narrow row is 0.45 meters. When sowing soybeans, 2 rows of soybeans are planted in the wide row of corn. The soybean variety is late-maturing Gongxuan No. 1, with a planting density of 7,500 plants / mu, and was sown on June 5. Early sowing of corn in mountainous areas (late March) and low-to-medium density are conducive to high soybean yield and double-crop production of corn and soybean.

Abstract

The invention belongs to the technical field of crop cultivation, and in particular relates to a method for cultivating soybeans and maize in the southern area by utilizing spatiotemporal dislocation on resources. The method comprises the following steps that: the maize selects compact type and middle short stalk early-middle maturity spring maize variety, and the soybeans select shade-tolerant lodging-resistant middle late maturity summer soybean variety; the maize is early sown at proper time, the soybeans are sown in time before or after rain of middle-late growing stage (May 25 to June 15) of the maize; the soybeans and the maize are planted by adopting wide-narrow rows, wherein the wide rows of the maize are 1.55m, while the narrow rows of the maize are 0.45m; when the soybeans are sown, 2 rows of soybeans are sown between the wide rows of the maize, and the distance between soybean rows is 0.45m, and the distance between the maize row and the soybean row is 0.55m; 2 plants of the maize are planted in each hole in two rows alternately, while 3 plants of the soybeans are dibbled in each hole in two rows alternately; nitrogenous fertilizer is applied to the soybeans according to the growing trend of field plants; and prevention and control to maize insects during symbiotic growing period of the maize and the soybeans are improved. The method sufficiently utilizes the advantage of niche complementarity of space and time of the soybeans and the maize in southern area on light, heat, water and earth resources to achieve the aims of improving the land utilization efficiency, improving peasant income, and realizing resource sustainable utilization.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a time-space dislocation cultivation method of southern soybean and corn resources. Background technique [0002] Soybean is an important crop that integrates grain, economics, feed and processing raw materials. my country is the country of origin of soybeans. Before the 1950s, it was the largest producer and exporter of soybeans in the world. However, due to the low yield per unit area, poor quality, and relatively low comparative efficiency, the cultivated area has been shrinking year by year, and has now been lost. The world's leading position in soybean production has been surpassed by the United States, Brazil, and Argentina. The contradiction between my country's soybean production and demand is very prominent. Since 1996, soybeans have been imported. In 2000, the import volume exceeded 10 million tons for the first time, becoming the world's largest im...
