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.
