Mustard planting method
Turn over the soil in time and apply base fertilizer to make it permeable. After soil preparation and planting, it can be covered with plastic film to keep moisture. You should plant real leaves when they appear. It is also necessary to pull out the sick seedlings in advance, change the seedlings in time and water them to keep the soil moist. Appropriate topdressing is also needed to prevent pests and diseases.
Key points of mustard planting management
1. Seedling management Mustard grows very fast. After emergence, the seedlings should be thinned. It should start with real leaf growth. When three real leaves grow, the seedlings will be fixed. Watch the spacing. Planting should not be too dense to avoid excessive growth of branches and leaves. 2. Intertillage weeding needs at least 1-2 times, which can reduce nutrient consumption and promote nutrient concentration in plant growth. It is also necessary to loosen the soil in time, enhance air permeability and drainage, and prevent soil hardening from affecting root respiration and growth. 3. Top dressing at the right time can be applied at the time of mustard planting, and you can lose weight later. Topdressing is mainly urea and potassium chloride, and the applied fertilizer should not touch the roots, so as not to burn the roots and affect the growth of mustard. 4. Insect-proof Mustard is very disease-resistant and will be invaded by aphids and cabbage worms. In the process of its growth, some diseases are prone to occur. It is necessary to strengthen management, do a good job of spraying drugs and trim the overgrown places with dense branches and leaves, which can increase ventilation and light transmission and reduce the occurrence of pests and diseases.
