Abstract

The invention discloses a method for broadcast sowing and planting of saline-alkali tolerant rice in saline-alkali soil, and belongs to the technical field of saline-alkali soil rice planting. The method for broadcast sowing and planting of the saline-alkali tolerant rice in the saline-alkali soil comprises the steps of (1) weeding before ploughing, (2) drought leveling, (3) soil directional conditioner and base fertilizer application, (4) rotary tillage and soil preparation, (5) field steeping and pulping, (6) water leveling, (7) seed pretreatment, (8) broadcast sowing and (9) later-period management. According to the rice planting method, sowing is conducted in a broadcast sowing manner, a soil directional conditioner is used in a combined manner, large-area saline-alkali-tolerant rice planting in the saline-alkali soil can be achieved, and labor input of rice planting is reduced; and the effects of improving the saline-alkali soil and increasing the rice yield of the saline-alkali soil can be achieved.

Description

technical field [0001] The invention belongs to the technical field of rice planting in saline-alkali land, and in particular relates to a method for sowing and planting saline-alkali-tolerant rice in saline-alkali land. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. [0003] Rice sowing cultivation is a labor-saving, cost-saving and efficiency-enhancing cultivation technology. As early as the early 1980s, a large number of experiments, demonstrations, an...
