A simple storage method for rice seeds

Abstract

The invention discloses a simple storage method of rice seeds, and the method comprises the following steps that 10 days to 15 days after a rice seed field is mature and when the seed water content reaches 20 percent to 24 percent, the seeds are harvested; the harvested seeds are air dried naturally, dried mechanically or treated by integrating the natural air drying and mechanical drying methods, so as to control the water content not to be higher than 18 percent; imperfect grains, dry leaves and grass seed impurities are removed mechanically, and the seeds are packed into woven bags by 60kg / bag; the woven bags filled with the seeds are piled and stored in a warehouse, wherein the piling method is wall-type stacking, the piling height is 5m to 8m, spaces are left around seed piles, an airway is left for every 3 to 4 woven bags on the same layer, and the airways on the upper and lower layers are staggered; the seeds are stored at room temperature, and the warehouse is exhausted for 24 hours once every month; before being sold, the seeds are mechanically dried again until the water content is 14.5 percent. According to the simple storage method of the rice seeds, the germination rate when sowing is guaranteed not to be lower than 90 percent, the conflict between high yield and insufficient mechanical drying capability in the seed harvesting season is effectively mitigated, the cost is minimized, the seed quality is ensured, and very good practicality is realized.

Description

technical field [0001] The invention belongs to the technical field of plant seed preservation, and in particular relates to a simple storage method for rice seeds. Background technique [0002] Seeds are one of the most important means of production in agricultural production. Moisture and germination rate are one of the national quality seed standards for seeds. The level of seed moisture affects the germination rate of seeds. The germination rate of seeds is maintained by controlling the level of seed moisture. [0003] Since the 1980s, the rural areas have implemented the household-to-household joint production contract system. Farmers have small farming areas, and small-scale farming has also led to small-scale, non-concentrated and contiguous seed breeding bases. The seed base involves a large number of farmers with a small area, but the small amount of seeds produced by the farmers is conducive to the drying of the seeds. The seeds are dried in a short period of time,...

AI Technical Summary

Problems solved by technology

[0004] 1. Seed drying cannot meet the needs. Most of the seed breeding bases planted by large growers are hundreds of acres or thousands of acres. It is impossible to rely on large-scale drying fields to dry seeds

[0005] 2. With the transfer of rural labor force to the city, the surplus rural labor force is reduced, and a large number of seeds need a lot of labor to turn and dry, and the labor force cannot be guaranteed

[0006] 3. The traditional seed warehouse is designed for long-term storage, and the construction cost of the warehouse is high

[0007] 4. There is a contradiction between the short harvest period and the long drying time
