1. Dry up early and catch the precipitation. The best time for seed drying is from the beginning of March to the end of April. If the seed stock is too large, it can be aired in advance according to the weather temperature. When the air temperature does not reach the storage standard, it can be turned over three or four times a day. The higher temperature weather can be turned over several times to speed up the precipitation. The storage seed temperature should not exceed 10 °C to ensure safe summer.
2. Seed storage. For each seed in the storage, insert 3 to 5 thermometers, divide the upper, middle, lower, left, and right points, and put 1 or 2 wet and dry meters in the bowl.

Closed fumigation was carried out before June 10 and August 10, respectively. The closing time is generally 5 to 7 days. At the same time, it will be dumped once in the middle and late July to prevent the cockroach from being overpressed. The germination rate will be reduced after the ventilating of the seed is not good. If the temperature inside the library is too high, the air blower can be used for ventilation.
3. Stock seeds are placed. The stock seed åž›, the bottom must be padded 35 ~ 40 cm, 10 sacks high, between 1 1.5 1.5 m wide ventilation and sidewalk between the åž› and the åž›, different varieties can not be mixed together, each åž› has a sign, The number and quantity of labels and defects. Outside the library, the bottom of the seedlings must be padded more than 40 cm. Use a mat to smash, no more than 10 sacks per squat. Use two layers of mats around the top of the shackle. Use a three-layer mat on the top and place one in the middle. The layer of plastic cloth is rainproof.
