Choosing good varieties is the key to growing corn, which directly affects the increase in corn yield. However, in recent years, many farmers have chosen a kind of blind seed when they choose a good breed, which brings them a large economic loss. Therefore, the following suggestions are proposed for reference.
1. When choosing to purchase seeds, be sure to select the corn seeds produced by Yuan. The seeds should have better packaging. There should be labels in the bags. The labels are clearly marked: manufacturer, quality standard, production date, place of origin, business license. The certificate number, etc., should also have a brief introduction and credit card of this variety in the seed bag. Do not buy for some three products.
2. Pay attention to the quality index when selecting. From the outside, the seeds are free of impurities, full and shiny, and the grain size is the same. Farmers' friends are most concerned about the problem of bud rate. When buying, they can bite with a tooth. Any seed produced in the same year will give a crisp crack when biting with a tooth. Generally, the seed germination rate will not be a problem, otherwise it will be bitten. Flat, so the seed germination rate may be problematic.
3. According to local production conditions, climatic conditions, soil conditions. Planting methods, etc. are selected.
(1) From the perspective of production conditions, where the production level is relatively high, such as a large amount of fertilization, a high culture of farmers and friends, and some new cultivation techniques and methods can be used, some high yields can be selected, and the fertilizer and water resistance are strong. , late-maturing varieties with lodging resistance, otherwise some adaptable medium-maturing varieties should be selected.
(2) In terms of climatic conditions, early-maturing and cold-tolerant varieties should be selected in areas with high alfalfa or high altitude in the short-term fertility season. For areas with sufficient rainwater, you can choose medium-late and late-maturing varieties with good tolerance and high yield. For those who are more prone to drought or no irrigation conditions, moderately mature varieties with strong drought resistance and relatively short plant growth should be selected.
(3) From the perspective of soil conditions, the selection of low-salt-salt-salt areas that are resistant to moisture, salt and alkali, soil ridges, and soil-leakage should be stable and stable.
(4) From the perspective of planting form, if you are going to use intercropping, you should choose a variety that is resistant to dense, high-yield, and lodging-resistant.
(5) From the point of view of the disease, if the pests and diseases are heavier, they should choose varieties that are more resistant to pests and diseases.
4. Do not simplify the variety. Generally choose a main push variety, with 2 ~ 3 auxiliary varieties, the main push varieties should be high yield, stress resistance, stable production, should also be short, to achieve high yield, stable production and balanced production.
5. It is recommended to rotate between varieties. That is to say, do not plant the same variety continuously on the same piece of land, and rotate the plants among the varieties in order to alleviate some pests and diseases.
6. Don't blindly seek new ones. Some new varieties do show good yield, but some have general performance, and they are poor in resistance and stability. Therefore, they should be promoted after local introduction. Do not blindly obey. The promotion of the business exaggeration.
