The improved varieties are the basis for high yields. The following four points should be taken when selecting corn seeds:
1. It is necessary to adapt the characteristics of the varieties and the cultivation techniques. When selecting the seed, it depends on the planting density of the variety. The suitable planting density is 4000-4500 plants/mu. The planting density will be chosen in this way, instead of being more or less; if the species is not resistant, the planting position is On the tuyere, you should choose a resistant variety; if this species is not resistant to locusts, and the species is in position to grow larvae annually, look for locust resistance. That is to say, characteristic features and selected solutions.
2, to be consistent with the purpose of planting. If there are several cows at home, they should use the food and feed varieties. After corn is harvested, straw silage; if selling fresh corn, it should be selected sticky corn; the purpose should be clear.
3, choose the same variety and sowing method. There are significant differences between seed varieties in terms of growth period, yield level, disease resistance, drought tolerance, lodging resistance, and adaptation to the area. Mo due to inappropriate selection of varieties led to reduced yields and even total production; interplanting in wheat lines Select the species to grow a little longer, the selected early maturing varieties after wheat harvest. The selection of seeds must be based on the growing habits of crop varieties.
4, after the purchase of species to be promptly asked for invoices, and safekeeping. Invoices are vouchers for seed sales. Seed users suffer losses due to seed quality problems. Seed operators should compensate them. The amount of compensation includes the purchase price, related costs and losses of available profits. Therefore, when buying a plant, you must ask for an invoice without an invoice. In this way, once the quality of the purchased seed is found, it can be claimed.
