Abstract

The invention aims to provide a method for cultivating soybeans obtained through drip irrigation under a mulching film. The method comprises the following steps of: pre-treating land, weeding, configuring a sowing mode, selecting seeds, sowing, applying a fertilizer and thinning, wherein a configuration mode of sowed plant rows is that: two mulching films are arranged, two drip irrigation systems are arranged under each mulching film, and each drip irrigation system is used for drip-irrigating three or four rows of young plants. The invention has the advantages that: after the method for cultivating the soybeans obtained through drip irrigation under the mulching film is applied, the soybeans are planted by 148th regiment in 2009, a water-saving drip irrigation technology is applied to the whole area, the average number of protected seedlings per mu is 23 thousand, the number of harvested plants per mu is 19,450, the average plant height is 86.4cm, the node number of main stems is 15.5, the pod number per plant is 32.4, the seed number per plant is 82, the hundred-seed weight is 20.1g, and the average yield per mu is 320kg; and yield classifications of the soybeans gradually tend to be balanced, and the difference among the yield classifications is gradually reduced.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a cultivation method for drip irrigation of soybeans under a film. Background technique [0002] Xinjiang Production and Construction Corps Agricultural Construction Eighth Division 148 Regiment Field (148 Regiment for short) is located at 86°06′-86°24′ east diameter, 44°34′-45° north latitude, on the southern edge of Jungar Basin, Mana Within the territory of Si County, it faces the Tianshan Mountains in the south, the Gurbantunggut Desert in the north, 185 kilometers away from Urumqi City in the east, and 78 kilometers away from Shihezi City in the south. The total area of ​​the whole regiment is 308 square kilometers, with an altitude of 353-362 meters, high in the southeast and low in the northwest. The existing arable land area is 192,000 mu, and the annual planting area is 180,000 mu. It is a typical continental climate, with 1950 hours of sunshine from April to October, and an ave...
