1. Select good varieties of summer radish cultivation should choose good heat resistance, strong resistance to early maturing varieties, such as red pill on the 20th small radish, Yang Hua radish and so on.
2. Soil fertility and early maturing radish has a short growth period and requires high nutrient content. It must combine with site preparation to apply basic fertilizer. Normally, 4,000 kg of fully-fertilized farmyard fertilizer and 40 kg of ternary compound fertilizer are applied per mu. Deep plowing and leveling the vegetable fields, and then do sorghum, 25 to 30 cm high. The gutter between the raft and raft should be deeper to facilitate drainage after the rain.

Excessive moisture, radish rough skin, but also easily lead to rooting and rot; When fertilizer and water is insufficient, the radish meat root is small and the degree of lignification is high, spicy, easy to worry heart, poor sense of convexity. According to the characteristics of the radish during the growth period and the need for a balanced water supply, we must not dry. After pouring seeds, water is poured. Most of the seeds need to be poured again after emergence to facilitate full seedlings.
