Last Updated: 2024/11/06, Radish is generally planted in autumn and listed in winter, but it has been successfully cultivated in summer in recent years, and the harvest period is in the off-season of 8-9 vegetables, so the income is higher and the planting prospect is good. However, the growth of radish with high temperature and heavy rain in summer is lower than that in autumn.

Radish is generally planted in autumn and listed in winter, but it has been successfully cultivated in summer in recent years, and the harvest period is in the off-season of 8-9 vegetables, so the income is higher and the planting prospect is good. However, the growth of radish with high temperature and rain in summer is lower than that cultivated in autumn, so how to get high yield in summer? Let's get to know it.

1. Select superior varieties

It is high temperature and rainy in summer, and the growth of radish is poor, so it is best to choose varieties with good heat tolerance, drought tolerance, strong resistance to diseases and insect pests and can form fleshy roots at high temperature. the better varieties are Hot White, Xiao Goubai, Xia Changbai 2, Dongfang Huimei, Xiakang 40 days and so on.

2. Soil preparation and fertilization

It is appropriate to select sandy loam soil with flat terrain, deep soil layer, good drainage and good water retention, and remove weeds and residual plants in the field in time after the previous harvest, and then apply fully mature ring fertilizer 4000 kg, potassium sulfate 15 kg, calcium superphosphate 30 kg per mu, deep ploughing and soil preparation, raking fine leveling, ridging cultivation, ridge spacing 80 cm, ridge height 15-20 cm, plant spacing 20 × 20-25 cm.

3. Sowing seeds

The sowing time of summer sowing radish can be sowed in batches from June to August according to the market demand. Hole sowing is suitable for large varieties, with a depth of 1.5 cm, 2 grains per hole, and a layer of sieve fine soil 2 cm thick after sowing. Medium type varieties use hole sowing or strip sowing, and the ditch depth of strip sowing is 2 cm 3 cm; small varieties can be sowed. The general large type varieties use about 0.5 kg per mu, the medium type varieties are 0.75 ~ kg, and the small varieties are 1.5 kg / mu.

4. Field management

The seedlings should be kept in time after emergence to ensure that the seedlings are neat and strong, the first seedling should be carried out when the cotyledons are fully expanded, and the second seedling should be carried out when the seedlings have 2-3 true leaves. When the seedlings grow out of 5 true leaves, it can be planted, combined with inter-seedlings for intermediate tillage and weeding, the middle tillage should be shallow first and then deep, so as not to damage the seedling roots. High temperature in summer, rapid evaporation of water, so according to soil moisture and radish growth characteristics of timely and appropriate watering, generally watering three times in the seedling stage, watering times and water should increase with the growth of radish in the peak growth period. Radish can not grow without fertilizer. Urea 8-15kg per mu is applied to promote leaf growth after seedling setting. When fleshy roots are exposed, 5kg urea, 10kg potassium sulfate and 3kg calcium superphosphate are applied with water to promote fleshy root swelling. When fleshy roots are enlarged, fleshy roots can be expanded by foliar fertilizer.

The above is the introduction of high-yield planting techniques of summer radish. I hope it can help you. If you want to know more about it, please follow us.
