Before sowing, it is limited to disinfect the soil. Potassium permanganate can be used to dilute and spray the soil on the seedbed, and then water the soil. After the water is sufficient, the seeds can be evenly spread on the seedbed. It is suggested that the seeds should be treated with catalysis. Then covered with sand, then covered with plastic film, about a week after the seeds can germinate.
Young seedlings are very fragile when they just sprout, so they should be carefully managed when they grow out. Pay attention to control the indoor temperature and water quantity. When the seedlings grow to a certain extent, they can be transplanted and planted. In addition, we need to pay attention to the application of sufficient base fertilizer before planting, and pay attention to the prevention and control of diseases and insect pests after planting. In order to prevent the occurrence of diseases and insect pests, you can take medicine once a week to prevent fungal infection.
In order to avoid self pollination, stamens should be removed before stigma dehiscence. The way of pollination is suggested to use the method of tube pollination, which is more labor-saving and fast. The disadvantage is that the yield is lower than that of artificial pollination.
