Greenhouse cultivation techniques of big cherry radish in fast-growing consumer market

Cherry radish tender quality, rapid growth, welcomed by consumers. In order to realize annual supply, the cultivation technology of solar greenhouse is introduced as follows.

cherry radish

1. Select varieties: select red varieties introduced from Japan, such as 20-day-old big roots, 2~3 cm in diameter, 15~20 g in single bulb weight, about 20℃ in growth temperature, 20~30 days in growth period;40-day-old big roots, 2~4 cm in diameter, 20~25 g in single bulb weight, 15℃~22℃ in growth temperature, 30~40 days in growth period, slightly longer in winter.

2. Fertilization and soil preparation: due to the short growth period of cherry radish, it is generally unnecessary to apply topdressing, so the base fertilizer should be applied adequately, 3000~4000 kg of manure per mu, and it must be decomposed and applied again to prevent burning seedlings. In addition, about 7 kg of calcium superphosphate can be used as seed fertilizer to promote expansion. Land preparation is generally flat, preferably neutral or slightly acidic sandy loam, and attention should be paid to improvement when using heavy clay soil.

3. Suitable sowing: Generally, sowing can be arranged from late September to early March of the following year, and annual cultivation supply can be formed by connecting with early spring and autumn open field cultivation.

4. Scientific sowing: suitable for direct seeding, multi-drilling, row spacing of 10 cm, ditch depth of about 1.5 cm, plant spacing of 3 cm, but also broadcast. To ditch watering, water infiltration after sowing, cover soil 1.5 cm thick or so. Cherry radish has a short growing period and short plants. It can be interplanted with crops with longer growing period to increase yield. For example, in the greenhouse and intercropping head lettuce, when the head lettuce will be closed before the ridge, cherry radish has been harvested.

5. Field management: 1. Adjust temperature and humidity. After sowing, keep it at 22℃~25℃, and it will be unearthed for about 2~3 days; after it is unearthed, properly cool it to 18℃~20℃, and let it out when it exceeds 25℃ (bolting will occur when the temperature is higher than 25℃ for a long time). The night temperature in winter shall be kept above 5℃. In principle, keep the field moist, the soil water holding capacity reaches 70%~80%, watering should be uniform. Generally early autumn and early spring late crop watering times more, late winter generally do not show dry water.

2. Rational fertilization. Generally do not need topdressing, base fertilizer can be insufficient with water flushing liquid fertilizer.

3. Thinning and settling seedlings. Thinning seedlings once when cotyledons are unfolded, and fixing seedlings in time before 3~4 true leaves. Pay attention to cultivation, loosening and weeding in the early stage.

4. Pest control. Due to the short growth period of cherry radish, there is generally no pest. Agricultural antibiotic 120, agricultural streptomycin can be sprayed to prevent diseases, and abamectin can be used to prevent insects in the early stage.

6. Timely harvest: Cherry radish fleshy root diameter 2~3 cm should be harvested in time, generally about 30 days after sowing and emergence, harvest too late fiber increase, and easy to crack roots, bran heart, affect the quality of goods.

VII. Precautions: Cherry radish should be planted well to prevent or reduce uneven shape, crack, fork root and bran core. The key is to apply enough decomposed organic fertilizer, loosen the land and keep the soil moist.
