1. For soil preparation and seed selection, deep plow the soil, apply foot fertilizer, and irrigate the soil moisture. Select a good variety, do a good job of soaking the seeds, dress the seeds with the medicine + the new high-lipid film 800 times solution (the new high-lipid film dressing can repel underground diseases and insects, isolate the virus infection, does not affect the germination and swelling function, strengthen the respiratory strength, and improve Seed germination rate). After sowing the seeds as required, spray 800 times the new high-fat film on the ground surface, which can protect moisture, water resistance, evaporation, sun protection, drought resistance, soil layer compaction, isolation of disease and insect sources, and increase seedling emergence.
2. Field management guarantees the supply of water and fertilizer in time according to the growth of radishes. It is necessary to cultivating and weeding, and keep the soil loose so that the soil is always moist and has a good air-permeable foundation. It is necessary to spray Diguozhuangdi Ling immediately during the seedling period to enhance the nutrient matching function, provide nutrient delivery, and promote rapid and balanced swelling of radishes. Only in this way can we fundamentally prevent the phenomenon of radish cracking.
