1. Choose a good variety. Good varieties are the internal cause of increasing production, and the selection of good varieties is the basis for increasing production. In terms of variety selection, the varieties and varieties of excellent varieties should be reasonably selected according to market needs, cultivation methods, sowing dates and other factors.
2. Seeding before sowing, graded grain selection. Fully drying the pods before sowing can break the seed dormancy, improve physiological activities, increase water absorption capacity, enhance the bud potential, and increase the germination rate. Generally, the fruit is dried for 2~3 days before sowing, and the shell is peeled after drying. At the same time, the seeds with large, full, uniform size and bright seed coat are selected for seeding, and the seeds can not be mixed with large and small seeds to avoid the formation of large and small seedlings, and the seedlings are bullied. Generate production cuts. According to the test, the yield of the first-class seed kernels increased by more than 20%, and the seeding of the secondary seed kernels increased by more than 10%.
3. Sowing at the right time to improve the quality of the planting. Whether the spring peanut sowing period has a significant impact on the yield. Sowing too early, affecting flower bud differentiation, and before the emergence of low temperature and rainy weather, easy to rot; sowing too late, can not make full use of the growth period, so that effective flowering, reduce pod development, reduce yield and quality. Different types of peanut varieties, the temperature required for germination is different, pearlpea type small peanuts require 5 cm of ground temperature to stabilize when planting above 15 °C. The Central Plains area is generally suitable for spring peanuts in the period from late April to early May, from the end of April to the beginning of May. During this period, we should consider the temperature of the year and pick up the seeds at the right time.
When planting, pay attention to reasonable close planting. Generally, the spring sowing density of ordinary erect large peanuts should be controlled at 8000~9000 points, two holes per hole. It can be used for dig hole on-demand, gully hole or mechanical seeding. Regardless of the seeding method used, care should be taken to ensure that the seeding is uniform, and the depth is consistent. Generally, the suitable depth is about 5 cm. After sowing, it is properly suppressed according to the lyrics.
