Soaking seed dressing soaking in warm water at 35°C for 15 minutes can increase the germination rate of buckwheat. Take 1 ~ 5 kg of ash in the water for 1 to 2 days soaking, soaking the seeds with plant ash liquid one day before sowing, spraying 10 kg of seeds with 1 kg of plant ash, after 3 ~ 4 hours, the seeds will not be agglomerated and can be sown.
The suitable buckwheat germinated at 15°C～20°C and was usually planted in the early August to early autumn. It only takes about 70 to 80 days from sowing to maturity, so it is important to grasp the ripening period of buckwheat before and after the frost fall.
Do a good job sowing buckwheat top poor soil, to achieve full seedling seedlings, sowing should be done in three points: First, the soil leveling and loose; Second, to apply enough base fertilizer, requires 667 square meters of high-quality decomposition of fertilizer 1 to 2 cubic meters Rice, mixed with calcium 20 kg; three to drill ditch, ditch depth of 3 to 4 cm, 4 to 5 kg per 667 square meters, row spacing of 33 to 35 cm.
One of the measures to strengthen management is timely cultivating loose soil. The first cultivator is carried out at a seedling height of 5 to 10 centimeters, and at the same time, the seedlings are grown at a distance of about 10 centimeters. In the future, the cultivator will be 1-2 times in proper time. Secondly, the seedlings should be top-dressed. When the seedling height is 10 cm, 5 to 6 kg of urea will be topped every 667 square meters. The third is artificially assisted pollination. Artificial pollination at the flowering stage, every day before and after 9 o'clock in the morning with a bamboo raft on the buckwheat plant towed it again, every 3 to 4 days drag once, even dragged 2 to 3 times, while paying attention to pest control hazards.
Timely Harvest Due to the inconsistent timing of the up and down flowering of buckwheat plants, the maturation period is not the same, and therefore cannot be harvested when the whole plant matures. When 70% of the plants are darkened and there is still a small amount of flowers in the upper part, they are harvested. Generally, it is appropriate to harvest when the dew is not dry in the morning.
Buckwheat cultivation method after flood
The seeds of the selected buckwheat cultivars are low in germination rate, and some do not even germinate. Therefore, large seeds harvested in the first year should be used. The method of identifying the germination rate of buckwheat is simple, as long as the buckwheat hull is peeled off, the endothelium of the seed that can germinate is green, and the seed that cannot germinate is yellow.
