Late stage Management of High quality Wheat

After returning to green, the period of getting up, jointing and raising the flag were all 5 days earlier than usual. At present, the seedling condition of wheat is close to that of the whole year, but the growth of the plots is not balanced. Therefore, it is suggested to strengthen the late management of high quality wheat:

1. Carry out fertilizer and water management of booting and heading as soon as possible: this fertilizer and water can not only promote floret development, increase floret seed setting rate and grain number per spike, but also promote nitrogen absorption and transformation in the later stage of wheat. it is one of the very important measures to improve wheat yield, protein content and wet gluten content (the compulsory index of national standard strong gluten wheat). Generally, in combination with irrigation, 5kg urea and 2kg potassium chloride should be applied.

2. Strengthen the management of the filling stage and improve the grain quality: the management of wheat at the filling stage focuses on protecting roots and leaves and promoting the accumulation of photosynthate and protein. Diseases, insect pests and weeds should be controlled in time, and plots with serious grass damage should be pulled out manually in time. Due to the great influence of irrigation and spraying on wheat quality during filling stage, irrigation and spraying should be controlled as far as possible under the condition that the degree of soil drought and the occurrence of powdery mildew were not very serious. Combined with pest control, extra-root fertilization (nitrogen fertilizer and potassium fertilizer) can reduce the decline of wheat quality.

3. Purification, rejuvenation and maintenance of seed character: the characteristics of wheat varieties gradually appear after flowering, so it is necessary to seize the time to get rid of miscellaneous and inferior wheat varieties. According to the conditions in the field, 2mi is generally purified three times to ensure the purity and character of the varieties and prevent degradation.

4. timely harvest to prevent mixing: the best harvest time of wheat is from the end of wax ripening to the full ripening stage, the harvest is too early, the grain water content is too high, the broken grains increase, and affect the processing quality of wheat at the same time. When harvesting, different varieties should be harvested separately, mixing is strictly prohibited, and the purity should not be less than 98%. Special attention should be paid to weather changes during harvest to prevent spike sprouting in case of rain, resulting in the loss of commodity value of wheat.

5, reasonable drying, ensure drying: drying on the cement ground or asphalt pavement, such as the stall is too thin, due to the high ground temperature is easy to cause wheat protein denaturation, reduce the processing quality. Therefore, the drying thickness of high-quality special-purpose wheat should not be less than 4mi 5cm, and at the same time prevent mixing when drying.
