Rice fertilization method applicable to saline-alkali soil

Abstract

The invention discloses a rice planting method applicable to saline-alkali soil. The method comprises the following steps: (1) seed treatment; (2) field treatment; (3) transplanting rice seedlings; (4) applying a striking root fertilizer, namely applying the striking root fertilizer after root striking of the rice; (5) applying a tillering fertilizer, namely applying urea and a compound fertilizerto rice at the tillering stage; (6) permanent flooding, namely performing permanent flooding after the rice enters the late tillering stage; (7) topdressing, namely applying urea at an elongation stage, wherein the water depth is 3-4cm; (8) applying an earing fertilizer, namely applying the urea, compound fertilizer and a potassium sulfate fertilizer after the rice enters a booting stage; and (9)applying a granule fertilizer, namely applying the urea and compound fertilizer when the rice enters a grain-filling stage; and performing alternate dry and wet treatment in the field. According to the method disclosed by the invention, the problem that fertilization is insufficient or excessive fertilizer is applied is solved, the production cost of the rice is saved while ensuring the rice yield, and sustainable development of the ecological environment is facilitated.

Description

technical field [0001] The invention relates to the field of agricultural technology planting, in particular to a method for applying tillering fertilizer suitable for planting rice in saline-alkali land. Background technique [0002] my country's saline-alkali land is rich in land resources, but the soil has high salinity, low organic matter content, poor soil aggregate structure, relatively poor soil, and relatively poor buffering capacity of soil fertilizer and water. Scarce, poor soil environment limits the growth of rice. [0003] The fertilization of rice throughout its life can generally be divided into base fertilizer, regreen fertilizer, tiller fertilizer, ear fertilizer, and grain fertilizer. [0004] The tillering stage of rice is the key period to ensure effective tillering, and it is also the key period to determine the number of rice panicles, and it is also the basic management for high rice yield. The tillering stage is the first peak period for rice to abso...
