"three precautions" in the growth stage of standard wheat

From planting to harvest, it takes more than half a year, spanning the whole winter, spring and early summer to enter the harvest season. Different natural disasters may be encountered in different seasons and stages of wheat growth. Therefore, disaster prevention and reduction and ensuring the quality of wheat are very important for increasing production and income. Experts suggest that farmers should achieve "three precautions" during the period of wheat growth:

To prevent low temperature and frost damage. At the beginning of wheat growth, it has to go through low temperature, rain and snow in winter. Moderate low temperature rain and snow is very beneficial to freeze and kill pests, loosen soil, increase natural nutrients and enhance the cold resistance of wheat. However, continuous low temperature will become a disaster, and different anti-disaster measures should be taken. The recovery of production in the wheat areas of the southwest and the middle and lower reaches of the Yangtze River after being damaged by rain and snow is mainly to do a good job of drainage and reducing stains, while the key points in the wheat areas of the northwest and the south of Huang-Huai are to increase temperature and preserve soil moisture and promote the upgrading and transformation of seedlings.

Second, prevent diseases, insect pests and weeds. Diseases, pests and weeds cause not only a reduction in production, but also a decline in quality. if the diseased grains exceed the standard, the price will be deducted or even cannot be purchased. Therefore, the control of diseases and insect pests is the key to increase production and income. In particular, the humidity of wheat field is high in the south, wheat diseases and insect pests and wheat field weeds and waterlogging damage often occur. It is necessary to formulate prevention and control plans, do a good job in forecasting and forecasting, and strengthen unified control and prevention.

Third, guard against post-disaster. In the middle and later stages of wheat growth, strong wind lodging, dry and hot wind and rotten field rain are the most harmful. The awn, ear, leaf and stem of wheat plant can be damaged by dry and hot wind. The grain dried up and the 1000-grain weight decreased. It is necessary to increase the application of organic fertilizer and phosphate fertilizer, deepen the tillage layer, select early-maturing varieties with strong stress resistance, mix seeds with drought-resistant agents, and do a good job of "one spray and three prevention" in the later stage.

Wheat is nearing harvest, and it is also a rainy season. The untimely exclusion of Rain Water not only reduced the yield of wheat, but also decreased the quality of wheat. If harvesting or threshing is not timely, it may sprout per ear and reduce the quality of wheat. During this period, in addition to doing a good job of ditching and drainage, we should pay attention to timely harvesting and machine harvesting as far as possible. Manual harvesting, whether with stone or mechanical threshing, will result in damaged grains and "imperfect grains". If the imperfect grain exceeds the standard, the price will be deducted.
