Summer spinach is difficult to plant for two reasons:
â— Seedlings after sowing are often exposed to heavy rain after sowing. This is very likely due to the difficulty of seedling emergence. In order to prevent the unfavorable effect of the emergence rate, slightly increase the sowing amount of spinach.
â— The management of the rainy season is to ensure that spinach is not dead. The main cause of dead trees is rain and disease. In summer, there is often rainfall. At this time, the ground temperature is high. If the rain drops to the middle of the field, it will have a great impact on the rhizomes of the spinach, or cause roots, or because of the hot, humid environment in the roots. The epidemic caused by the disease will cause spinach to die. Therefore, it is crucial to take correct management measures at this time.
For these two situations, two approaches can be taken to solve spinach dead trees:
â— Drain the water immediately after the rain, and use the well water to carry out the pouring of the garden. It should be noted that after the water is poured, there must be no accumulation of water in the field. Otherwise, it is likely to cause roots.
â— Pay attention to the prevention of damping-off, downy mildew, stem rot, bacterial rot and other diseases. Can be used after the entire seedling with chlorothalonil, propofol 600 times liquid spray 1, can be sprayed later streptomycin, mesitactin and other bacterial disease prevention, this can effectively prevent the occurrence of dead spinach.
