Hybrid Rice Seeds, “Prevent, Grab, and Dry”

In view of the increase in rainfall and the increase of the frequency of natural disasters during the harvest of seeds in Zhangzhou, Hunan Province in recent years, the seed quality of hybrid rice seeds and the benefits of farmers are affected. In order to do a good job in late-stage rice management and timely harvesting, Hunan Province Zhangzhou Longping Gaoke Seed Co., Ltd. took "anti-, grab-and-dry" measures: First, "defense" in the latter part of management. That is to say, in the mature stage of seed production and flowering, the management of fertilizer and water should be effectively carried out, and the amount of “90%” should be controlled to prevent the plants from lodging and lodging, and the pesticides should be used to prevent and control pests in time. When the seed matures, the yellow silk stalk is stalked, the ear layer is clear, the smut of rice grain is prevented, and the sprouting of the seed is occurred. The second is the "grab" of mature harvesting period. That is, when the seed matures 80%, according to the weather forecast organization, the labor force rushes to snatch and threshing. And in the process of collection, it prevents mud from contaminating the seeds and ensures that the seeds are bright and bright. Farmers with small labor force and large planting area should adopt measures such as short-term labor and mechanized harvesting to ensure that mature seeds rush to harvest before the rainy day. The third is the "drying" after the rain. After the seeds are collected, if they encounter rainy days, they must do everything possible to spread out air and prevent stacking fever. We must make full use of cement and wood floor thin booths to dry the seeds, vigorously promote the drying of bamboo curtains and low-temperature drying to reduce the moisture and clear the sun.
