What should you pay attention to before harvesting wheat? The following points should be paid attention to in harvesting wheat: first, the most suitable harvest stage for wheat is from the end of wax ripening to the full ripening stage. The suitable harvest time is high yield, good quality and high germination rate. Early harvest, not full grain, low yield and poor quality. When the harvest was too late, the protein content, carbohydrate, 1000-grain weight, bulk weight and flour yield decreased due to respiration and Rain Water leaching, so it was easy to drop grains in the field and sprout on the ear in case of rain, and some varieties were easy to break stalk and drop ear. Second, the performance characteristics of wheat at wax ripening stage and full ripening stage. At the early stage of wax ripening, the leaves were yellow but not dry, the grain was light yellow, the groin was chlorotic, and there was no pulp in the grain. In the middle stage of wax ripening, the lower leaves are dry and yellow, the stem is elastic, the grain turns yellow, full and moist, and the seed water content is 25-30%. At the end of wax ripening, the whole plant turns yellow, the stem is still elastic, the grain is yellow and hard, and the water content is 20-25%. At the full ripening stage, the leaves withered and yellow, the grains hardened, showing the true color of the variety, and the water content was less than 20%. Third, the choice of harvest time 1, manual harvesting and mechanical cutting and drying. The harvesting and threshing are divided into two stages, and the wheat stalks cut down in the middle to the end of wax ripening can still transport nutrients to the grains, so it is appropriate to harvest in the middle to the end of wax ripening. This harvest method can start 5-7 days earlier than the direct combined harvest. 2. When using the combine harvester to harvest directly, it should be carried out from the end of the wax ripening to the full ripening period. 3. The wheat fields reserved for seed are harvested in the mature period. 4. If the rainy season is approaching, or there is an urgent need to plant the next crop, or the varieties are easy to drop grains, broken stalks, broken ears, ear sprouting and other reasons, they should be harvested in advance. Fourth, wheat drying and storage wheat after threshing, quickly remove the grain inclusions, air drying, reduce grain water content, wheat grain storage safety moisture standard is less than 1.4%. During storage, grain moisture and temperature must be controlled to prevent mildew, insect, rat, bird and fire, and seeds should also pay attention to prevent mixing.
