Method for high-efficiency fully-mechanized planting of regenerated rice

Abstract

The invention discloses a method for high-efficiency fully-mechanized planting of regenerated rice. The method includes the following steps that s1, early-maturing rice varieties with good quality andstrong regeneration ability of low nodes are selected for planting, wherein the sowing time of the first-season rice of the early-maturing rice varieties is mid-March, and the harvest time is beforeAugust 5; s2, 10 days after full heading of the first-season rice, 15 kg of a compound fertilizer is applied per mu to protecting roots and shoots so as to ensure the vigor of roots and low-node regeneration buds, wherein the mass ratio of N:P2O5:K2O is 22:8:10 according to the formula of the compound fertilizer; s3, before August 5, mechanized harvesting of the first-season rice is conducted, lowpiles shorter than or equal to 5 cm are reserved, irrigation with shallow water is conducted in time after harvesting, and 5 kg / mu of urea is applied as a seedling promoting fertilizer; s4, mechanized harvesting of mature regenerated rice is conducted in early October; s5, a rice dryer is used for uniformly drying the harvested rice according to the standard moisture content. The method for high-efficiency fully-mechanized planting of the regenerated rice can be adopted to effectively solve the problems existing in the prior art that the high yield and stability of the regenerated rice are limited due to insufficient light and temperature resources in the later period, press piles and ear layers of mechanized harvesting are uneven due to too high reserved piles, and the like.

Description

technical field [0001] The invention belongs to the technical field of ratooning rice cultivation, and in particular relates to a whole-process mechanized high-efficiency planting method of ratooning rice. Background technique [0002] The ratooning rice is planted once and harvested twice, that is, after the first season of rice is harvested, the rice piles are used to re-emerge seedlings and grow ears, and then harvest another season of rice. Raising rice is a type of rice that has a long history of cultivation in China, dating back to 1700 years ago. Its characteristic is that after the first season of rice matures, only about 2 / 3 of the upper part of the rice plant is cut off, and the ears of rice are harvested, leaving the lower 1 / 3 of the plant and root system, fertilized and cultivated, so that it can grow another season of rice. The areas suitable for planting ratooning rice are mainly those areas where the sun and heat are not enough to plant two crops of rice, but...

Problems solved by technology

[0003] The purpose of the present invention is to provide a full-process mechanized method for the problems existing in the prior art, such as the high yield and stable yield of ratooned rice due to the lack of light and temperature resources in the later period, and the excessive height of the piles caused by machine-retracted piles and uneven ear layers. High-efficiency planting method of ratooning rice, solving the problems that restrict the high and stable yield and mechanical harvest of ratooning rice
