The late wheat growth period refers to the stage from heading to maturity, and is also the period of wheat economic production (grain), and it is the most critical and most important period for wheat management. During this period, the supply of water and nutrients in the wheat field has a direct impact on the formation of yield. Therefore, we must conscientiously do a good job of water and fertilizer regulation to meet the normal physiological and physiological needs of wheat and prevent the emergence of two extreme phenomena: First, defertilization (due to malnutrition often easily lead to premature decline in production), and second, greediness (since overnutrition is often easy to cause Prolonged late mature dry. The management of the later period should be carried out around raising the roots, protecting the leaves, keeping grain, and increasing the weight. From booting to heading, it's wheat life Critical period. If the wheat is affected by drought during this period, it will reduce the production seriously, so it is required that the soil in the wheat field be suitable for this season. Simultaneous application of fertilizer should be cautious, according to the wheat seedlings targeted specific root spray fertilizer. For wheat fields with general seedling conditions, potassium dihydrogen phosphate should be added to increase the strength and rate of grouting, increase grain, increase weight, and increase yield. For wheat fields with signs of defertilization (yellow leaves, weak population growth, and spider mites), urea, amino acids, and trace fertilizers should be added to promote greening and greening and delay aging. For those wheat fields that grow too busy and have a long-term trend of greediness (leaves are dark green and the groups are oversized and dense), they should be protected against disease, prevent late-maturing, strictly control watering, and prohibit the use of various fertilizers. No drought or no irrigation, no spraying of nitrogen-containing foliar fertilizers, and spraying pesticides to prevent and treat pests at the later stage. General spray fertilizer can be combined with pest and disease prevention and control, comprehensive consideration and comprehensive utilization, and “one spray and three defenses†from the booting stage to the grain filling stage. Can use 150g of potassium dihydrogen phosphate per acre (supplement fertilizer), 1.8% of avermectin cream 20ml (control insects), 20% triadimefon EC 40ml (prevention of disease), 0.1% 481 brassinolide 5g (inflammation ), spray 50 kg of water, spraying 2-3 times in intervals of 7-10 days. However, it should be based on the situation of wheat seedlings, diseases and insect pests, etc., adjust the increase and decrease of pesticides and fertilizers to ensure its practical effect of disease prevention and pest reduction and yield increase.
