The so-called late wheat reproduction period refers to the fertility process of wheat from flowering, pollination, filling and maturation to the last month. This process is critical to the quality and yield of wheat. The following measures should be taken care of: A lot of water, according to soil moisture, seedlings timely pouring good heading, Yanghua, grouting and wheat yellow water, to meet the water needs of wheat. In particular, grout water not only satisfies the need of wheat grouting for water, but also stabilizes the ground temperature and prevents root premature aging, thus playing the role of water rooting, root protection, and leaf protection. Wheat yellow water has a certain role in resisting dry hot wind, but the amount of water should not be too large, so as to avoid root rot suffocation, a significant drop in grain weight. For grain-filled black-green wheat fields, in order to prevent late-maturing lust, it is necessary to stop the water as early as possible, and watering at the latter stage should also be taken to prevent lodging. The practice of applying fertilizers from the roots has proved that foliar fertilizer such as potassium dihydrogen phosphate, high yield producing spirit, and enzyme bacteria can be sprayed after flowering of wheat, which can significantly improve the quality and yield of wheat. In general, 0.1 kg of potassium dihydrogen phosphate and 50 kg of water are used per acre, and an appropriate amount of high yield factors is added. After the fertilizer is dissolved, it can be sprayed. The best time is after 4pm for the absorption of leaves. After flowering, if the wheat leaves are yellow-green and there are signs of premature death, 500-1000 grams of urea can be sprayed per acre (should not be too much). Prevention of Diseases and Pests Many diseases and insect pests in the late growth stage of wheat have to be treated with pesticides in time. If there is powdery mildew, it can be sprayed with 40 to 60 ml of 20% triadimefon per acre or 500 times of 25% carbendazim for spraying; for aphids, it can use 1000 times of 20 grams of 40% omethoate per acre. Or 50% anti-inferiority WP can prevent and control, can also use 10% imidacloprid or 24% Tim wettable powder 2500 ~ 5000 times spray control. The weight of 1000-grain wheat harvested in a timely manner ranges from grouting to the end of wax production, with an average weight gain of 1 to 2 grams per day. At the end of wax ripening, the protein content is higher and should be harvested in time. If the harvest is too late, the grain dehydration becomes hard, the glume is loose, and it is easy to drop grain; the ear and stem are brittle, and it is easy to drop the ear; the varieties with short ripening period will also germinate on the ear when raining.
