Prevent onion convulsions from catching three points
The first is sowing. Proper sowing is not only the key measure to prevent onion convulsions, but also the key to high yield. In Shandong Province, from late September to mid-October, it is a timely sowing period. It can avoid the defects of large seedlings growing early (in early September), large pseudostems exceeding 0.6 centimeters, and increased seizure rate. It is possible to avoid the situation of small seedling growth, small bulbs, and low yield due to late sowing (in late October). The second is to grasp the time of planting, and to plant strong seedlings. Generally from November to December, colonization is better, and strong seedlings are selected for planting. Planting strong seedlings grow rapidly after the Spring Festival, the bulbs swell quickly, the rate of bolting is low, and the yield is high; if the planting large seedlings, the large amount of growth during the winter, after the Spring Festival reproductive growth is strong, the bolting rate is very high, the yield is low; and planting seedlings, due to growth Insufficient in quantity, its bulbs are small and the yield is low. The third is to grasp fertilizer and water management. During the winter, no fertilizer is applied. After the Spring Festival, 3 fertilisers are chased after the Spring Festival. In the middle of March, they chase the first time. In mid-April, they chase the 2nd time. In early May, they chase the 3rd time, each time applying topdressing urea 15-25 kg/mu. Potassium sulfate 5-7 kg/mu, to promote its vigorous growth, inhibit reproductive growth, reduce the rate of convulsions. In addition, when there is convulsions in the field, it is necessary to fight in time to reduce the loss of production.
