How to prevent yield loss during wheat harvest? What factors can cause yield loss?
The maturation process of wheat includes two stages: the dough stage and the full-ripe stage, and the best time to harvest is the late dough stage. This is because the thousand-grain weight of the kernels reaches its maximum at the late dough stage, and harvesting at this time gives the highest yield. If the harvest time is improper, whether too early or too late, it will lead to yield loss. At present, farmers commonly harvest wheat either too early or too late, and this problem should draw the attention of farmers.
The suitable harvest window for wheat is very short, generally 3-5 days, and timely harvesting is also a guarantee of a bumper wheat harvest. If harvested too early, since grain filling is still continuing before the late dough stage, harvesting at this time means the kernels are not fully filled and have high moisture content, artificially causing a decrease in the thousand-grain weight of wheat, as well as mechanical damage during threshing and incomplete threshing and separation, resulting in reduced quality and yield of wheat; if harvested too late, after the late dough stage, dry matter accumulation in the kernels stops, the root system begins to senesce, while the plant is still respiring, and the nutrients it needs are absorbed from the wheat grains, which easily leads to "nutrient backflow" and a decrease in thousand-grain weight; if rainy weather occurs, not only is the kernel content easily consumed by respiration, reducing the thousand-grain weight, but it also often causes sprouting in the head, or leads to moldy kernels, severely reducing the yield and quality of wheat; the plant becomes brittle due to excessive water loss, and the wheat heads become too dry, which easily leads to mechanical damage during mechanical harvesting such as broken heads, snapped heads, and shattered kernels, reducing wheat yield; at the same time, when strong winds occur, some wheat kernels will also be blown off, further reducing yield. Finally, farmers are reminded that wheat must be harvested at the right time; neither too early nor too late is advisable.
