Method for planting and processing ratoon rice

Abstract

Disclosed is a method for planting and processing ratoon rice. The method comprises the steps that 1, a not-easy-to-fall variety without pests and diseases with strong regeneration ability, and excellent rice quality is selected; 2, seed cold induction processing is conducted in February every year, seed soaking is conducted in middle and late March, breeding is conducted after seed soaking is conducted for 30-40 hours, and heat preserving and rice seedling raising are conducted in the process; rice transplanting of the first season is conducted in late April; 3, field management is conducted,and the field management comprises field drying, fertilizer applying, preventing and controlling of pests and diseases and water management; 4, harvesting is conducted, and the harvesting time of thesecond season is delayed compared with the harvesting time of regularly planted rice; 5, processing is conducted, and the processing comprises the working sections of cleaning, husking and rice milling. According to the method, by selecting an excellent original longevous rice variety and a cold induction processing technology, a foundation is laid for obtaining rice with high quality and high yield through the ratoon rice, and the yield is increased by 20% compared with the rice planted by a conventional method in the same period by combining and optimizing the sowing time and the field management. The method has the advantages that the quality of rice is good, pesticide contamination is not contained, the processing cycle is scientific and reasonable, and the quality of finished products is high.

Description

technical field [0001] The invention belongs to the technical field of crop planting and processing, and in particular relates to a method for planting and processing ratooned rice. Background technique [0002] Raising rice is a kind of rice variety. It has a long history of planting in China. It is characterized by harvesting only the upper two-thirds of the rice plant after the first season of rice is mature, and harvesting the rice ears, leaving the lower one-third of the plant And root system, fertilize and cultivate, let it grow another season of rice. Although this technology is relatively old, the success rate is low, and the yield of the second crop rice is not high. In addition, there is a unique original grain species in the Zhongxiang area, called the original Changshou Valley, which has a history of nearly 500 years. It maintains the original rice seed gene and has excellent quality. In order to realize the high yield of rice with this excellent quality, it is ...

Problems solved by technology

Although this technology is relatively old, the success rate is low, and the yield of the second crop rice is not high. In addition, there is a unique original grain species in the Zhongxiang area, called the original Changshou Valley, which has a history of nearly 500 years. It maintains the original rice seed gene and has good quality. In order to realize the high yield of rice with this good quality, it is necessary to conduct research on its planting and processing to meet the needs of people's consumption.
