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

Embodiment 1

[0028] The newly harvested seeds (Lianjing No. 7) were dried by mechanical drying, and the temperatures of the drying machines were set at 42°C, 43°C, 44°C, 45°C, 46°C, 47°C, 48°C, respectively. °C, 1000 kg of the same batch of freshly harvested seeds (water content 22%) were taken, and dried at the set temperature until the water content was 14.5%. Record the drying time of each sample, and detect the germination rate of each sample.

[0029] The result is as figure 1 As shown, when the temperature is set to 42 ℃, the germination rate after drying is the highest, but the required drying time is the longest; when the temperature is set to 44 ℃, the germination rate after drying and the temperature is set to 42 ℃ and 43 ℃ compared the difference was not significant ( P<0.05 ), but significantly higher than the germination rate of subsequent temperature settings, and the time required for drying is relatively short. Therefore, the mechanical drying temperature was chosen to b...

Embodiment 2

[0031] 100 kg of the newly harvested Lianjing 7 rice seeds were removed from impurities (October of the current year), and then dried at 44 °C until the moisture content was 15%, 16%, 17%, 18%, 19%, and 20%. , 21%, and 22%, were packed in plastic woven bags and placed in the warehouse respectively, each treatment was covered with film respectively, and stored at room temperature. The germination rate was checked separately in April of the following year.

[0032] The result is as figure 2 As shown, when the water content is 19%, the germination rate is 86%, which is only 1 percentage point higher than the national minimum standard; when the water content is 18% and 17%, the germination rate is 92% and 93%, respectively, and the The difference was not significant; when the water content was 16% and 15%, the germination rates were 95% and 96%, respectively, and there was no significant difference between the two. Considering other risk factors and cost factors, it is determin...

Embodiment 3

[0034] After 60,000 kg of freshly harvested Lianjing No. 7 rice seeds were removed (October of that year), they were mechanically dried at 44 °C to a water content of 18%, packed in plastic woven bags, 60 kg per bag, and divided into 3 batches (20,000 kg per batch) are stored in the same warehouse, and each batch of seeds adopts one palletizing method: palletizing method I adopts wall-type palletizing, and each layer has ventilation holes; palletizing method II adopts wall-type palletizing, There are no ventilation holes in each layer; the stacking method III is tightly stacked. Check the germination rate of the seeds in April of the following year.

[0035] The result is as image 3 It can be seen that the effect of palletizing method I is the best, followed by palletizing method II, and the effect of palletizing method III is the worst.

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,...
