Embodiment 1

[0034] A method for planting ratooned rice in karst areas, comprising the following steps:

[0035] (1) Rice planting: in mid-April, apply base fertilizer in the paddy field, apply 400kg / mu, after deep plowing and leveling, transplant the seedlings into the rice seedlings according to the specifications of 4×7 inches;

[0036] (2) Tillering stage management: 5 days after the seedlings are transplanted, apply tillering fertilizer in the paddy field, and apply 10-12kg per mu;

[0037] (3) Green fodder harvesting: Harvest rice plants at the peak seedling stage as silage raw materials, and leave rice piles with a height of 5-8cm in the paddy field;

[0038] (4) Rice pile management: Spray antibacterial solution to rice pile after harvest; apply nutrient fertilizer to rice field after spraying antibacterial solution for 4 days to promote the growth of tiller buds;

[0039] (5) Regenerated rice management: topdressing ear manure and grain manure at the young ear differentiation sta...

Abstract

The invention belongs to the technical field of rice planting, and particularly relates to a Karst region ratooning rice planting method which includes the steps: rice planting; tillering stage management; green feed harvesting; rice pile management; ratooning rice management. According to the planting method, rice plants are cut at a peak seedling stage of rice to serve as raw materials of silage, ratooning rice is cultured by remained rice riles after cutting, double harvest of the high-quality silage and rice can be achieved, reasonable fertilization and field management is implemented, theyield of the high-quality silage and the rice is increased, and comprehensive economic benefits of the rice are improved.

Description

technical field [0001] The invention belongs to the technical field of rice planting, in particular to a method for planting ratooned rice in karst areas. Background technique [0002] Rice is an important food crop for humans, and about 50% of the world's population uses rice as a staple food. In Asia, the population whose staple food is rice accounts for about 95% of the total population in Asia. In recent years, with the increase of population and the drastic reduction of available land, our country is facing the pressure of food demand. Therefore, research on super-high-yield breeding and cultivation of rice has received much attention, and maximizing the genetic potential of crop varieties and improving cultivation management techniques have always been the focus of agricultural research. [0003] Ragnarok rice is a type of rice cultivation that utilizes the regeneration ability of rice, and through cultivation and cultivation measures, the dormant buds surviving on t...
