Cowpea planting generally chooses the way to sow seedlings, but in the process of nursery, the phenomenon of seedlings often appears. How to deal with this? In fact, the method is very simple. If you want to get out of the seed, you need to master the time, temperature and water and fertilizer management of seedlings. The following are detailed seedling techniques, you can refer to.     1, Shiji fertilizer Pay attention to the choice of fully decomposed organic fertilizer, and it is not appropriate to use too much nitrogen fertilizer to make fertilizer.     2, timely seeding The sowing date should be adapted to local conditions. Generally, when the temperature of 10 cm is stable above 12-13 °C, it can be sown. If you need to plant early, you can carry out film management.     3, control the temperature after the broadcast Cover a thin layer of fine soil, soak it properly with water, not too much to prevent rotten seeds. During the nursery period of cowpea, attention should be paid to temperature and nutrient management to cultivate strong seedlings. The seedling age of cowpea is generally about one month. When the seedlings are released, the seedlings need to be cooled in time. The temperature is maintained at 15-20 °C during the day and 10-15 °C at night to prevent the seedlings from growing. When the first true leaf (foliate) is unfolded until 10 days before planting, the temperature needs to be increased. Generally, the daytime is 20-25 °C, and the nighttime is 15 °C-20 °C, which can effectively promote flower bud differentiation and leaf. Growing. About 10 days before planting, seedlings should be subjected to low temperature exercise. During the first 5 days, the daytime temperature is 15 °C-20 °C, and the nighttime is 10 °C-15 °C; the last 5 days is lower, and the temperature can be lowered to 12 °C-5 °C at night. Cowpea is basically not watered in the seedbed. When it is too dry, the water can be sprayed with a watering can. The seedbed is filled with water one day before planting, which is beneficial to transplanting seedlings. Seeding and seedling cultivation is a traditional breeding method in China. However, in the process of seedling raising, the phenomenon of seedling emergence often occurs, and the effect of seedling cultivation is not good. In order to improve the sprouting rate of seedlings, you must control the relevant factors such as time and temperature. The above is a detailed operation method that everyone can learn from.
