When is the radish generally sowed? In some climate-friendly areas, all seasons can be planted, and in some areas, depending on the climatic conditions, radishes can not only be eaten, but also have many effects. Today we have to talk about the high-yield planting points of radish.
1. Soil preparation and fertilization
Radish planting should not be continuous with cruciferous vegetables, deep ploughing and turning over, while applying base fertilizer, applying 3.7 to 45,000 kilograms of decomposed organic fertilizer per hectare, 1200 kg of plant ash, 375-450 kg of superphosphate, and 750 kg of diammonium phosphate.
2. Lighting requirements
Radish growth requires sufficient sunshine, sufficient sunshine, strong plants, strong photosynthesis, more material accumulation, rapid expansion of fleshy roots, high yield, and the completion of vernalization of plants in long sunshine and higher temperature, flower bud differentiation and flowering Faster.
3. Moisture requirements
The effective water content of the radish suitable for the growth of the fleshy root is 65-80%, and the air humidity is 80-90%. The humidity of the air can improve the quality, but the soil moisture should not be too much. If the water supply is uneven, the fleshy roots are easy to crack.
4. Temperature requirements
The radish is a semi-hardy-tolerant vegetable. The seed can germinate at 2~3°C, the temperature is 20～25°C, the seedling stage can withstand the temperature of 25°C, the temperature can be minus 3°C, and the stem and leaf growth temperature is 15-20°C. The fleshy roots grow at a suitable temperature of 18-20 °C.
5. Soil requirements
The radish is not strict with the soil, but the soil is deep and the soil is loose. The sandy loam with good water and water retention and good fertilizer retention is the best. The pH value of the soil is 5.3-7.
6. Seeding at the right time
The sowing date of radish is determined by variety characteristics and market needs. The suitable sowing date for autumn and winter radish is from late July to early August. Spring radish can be sown from late February to early April. The seeding rate varies with cultivation density, generally 3 ~ 6 kg / ha.
7. Time seedlings
The radish planting is usually carried out in the first time when the first true leaf is unfolded, and the strong seedling with the characteristics of this variety is selected when the big belly is broken. Other weak plants can be dropped.
8. Watering
The soil moisture content of radish is more than 90% during germination, 60% is suitable for seedling stage, water demand is high during leaf growth period, soil moisture is maintained at 70-80% during root growth period, and water should be properly watered during root growth. To prevent hollowness.
9. Top dressing
The principle of radish fertilization is based on base fertilizer, supplemented by topdressing. Generally, after topdressing, the fertilizer is applied 2 to 3 times. Avoid excessive concentration. The ratio of potassium, nitrogen and phosphorus is about 2:1:2.5.
10. Interplanting weeding
When planting radish, pay attention to the work of cultivating, weeding and earth-cultivation, especially in autumn. The temperature is warm, the rain is high, the weeds are easy to grow, and weeding and weeding should be carried out in time.
11. Pests and diseases
The main pests of radish are aphids, diamondback moth, cabbage caterpillar, yellow stripe, etc. The main diseases are virus disease, downy mildew, soft rot, etc. Field management should be strengthened and preventive measures should be taken.
12. Harvest at the right time
The harvest time of radish is different for different sowing dates. Spring radish should be harvested after about 50 to 60 days after sowing. Summer radish and early autumn sowing are harvested 40 to 60 days after harvesting. Most of the radish roots in autumn and winter radish are exposed on the ground. The varieties of the department were harvested before the frost.
The above is the high-yield cultivation method of radish. Do you think it needs to be supplemented? What other points are you want to know what you want to learn, leave a message!
