Can rice be grown in saline-alkali land?
1. Adequate water source is beneficial to irrigation, which provides necessary water source guarantee for improving saline-alkali land with fresh water washing alkali and hydraulic alkali, and ensures the normal growth of rice.
Rich in light and heat resources. The sunshine hours from April to September 1700- 1800 h, the effective accumulated temperature ≥ 10℃ and the frost-free period 150- 170 d can fully meet the growth needs of rice.
Saline-alkali soil is sticky and belongs to red clay. Rational utilization of sandy soil resources can turn saline-alkali land into soil and increase soil permeability. At the same time, straw, wheat straw and other crop straws are used to return to the field to improve soil fertility.
2. Technical measures for planting high-quality and high-yield rice in saline-alkali land.
In addition to the general rice high-yield procedure, it is necessary to transform strip fields and level the land, select excellent drought-tolerant and barren-tolerant varieties, and apply more organic fertilizers to ensure the success of rice planting in saline-alkali land.
