Embodiment 1

[0043] In this example, the implementation of the ecological conditioning method of drip irrigation under plastic film and salinized cotton field in Xinjiang Korla Bazhou water pipe irrigation test station from 2016 to 2018:

[0044] The area of ​​the cotton field is 3 mu, and the planting method of one film, two tubes and four rows is adopted. The distance between the wide row, the narrow row, and the film is 40cm, 20cm, and 30cm respectively. The drip irrigation belt is laid in the middle of the two narrow rows respectively. The water consumption is 2.2L / h, the distance between the emitters is 40cm, and the surface canal water is used for irrigation, and the salinity is 0.83-1.03g / L. Before cotton sowing, prepare humic acid solution 2 at a rate of 1.5 kg / mu, spray evenly on the cotton field with a watering can, and plow through a rotary tiller to fully mix humic acid solution 2 with the soil. After the cotton is sown, sow halophytes 6 (salica, Suaeda salsa, alfalfa) on the b...

Abstract

The invention discloses a mulched drip irrigation salinized cotton field ecological conditioning method. The method specifically includes the following steps that 1, before seeding, a humic acid solution is sprayed; 2, halophyte is sown; 3, the halophyte is covered with cotton straw; 4, water is supplemented to the halophyte; 5, the humic acid solution is applied to a field; 6, the halophyte is harvested. The method solves the problem that salt of an existing mulched drip irrigation cotton field is hidden and threatens the sustainability of the mulched drip irrigation technology.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency utilization of agricultural land resources and improvement of saline-alkali land, and relates to an ecological conditioning method for salinized cotton fields by under-film drip irrigation. Background technique [0002] Saline-alkali land is widely distributed in Xinjiang. Since 1996, the No. 8 Agricultural Division of Xinjiang Construction Corps used drip irrigation under plastic film to plant cotton in saline-alkali land and achieved good results, and drip irrigation under plastic film has been widely used in Xinjiang. According to the latest statistics, the cotton drip irrigation area in Xinjiang has exceeded 30 million mu. Under-mulch drip irrigation has the advantages of saving water, fertilizer, salt, and increasing production. However, under-mulch drip irrigation does not take away the salt from the soil, but changes the local soil water-salt distribution. Although in a short period...
