Radishes are generally cultivated in the fall and are supplied to the market in winter. In recent years, the cultivation of summer is successful, and the products are supplied to the market in the off-season, which not only meets the needs of consumers, but also enables producers to obtain higher economic benefits.
The selection of fine varieties of radish for off-season cultivation in summer should be carried out under high temperature conditions, with good growth, crispy, sweet, and fleshy roots. Suitable varieties are Lulu No. 8 and Xia Kang 40. These two varieties weigh 0.5 to 1 kg per plant, white skin white meat, 3000 to 4000 kg per 1 / 15 hectares of fresh radish.
After timely fertilization and wheat harvesting, 5000 kg of high-quality decomposed organic fertilizer and 50 kg of vegetable special compound fertilizer are used as base fertilizer per 1/15 hectare. Grab the ploughing and ploughing, the ploughing depth is 20~25 cm, and the ridge is flattened and ridged. The ridge distance is 55~60 cm, the ridge top is 20 cm wide, the ridge height is 20 cm, the length is no more than 50 m, and the ridge is north-south.
Make sure that the seedlings are planted in mid-to-late June. When sowing, you can open the shallow ditch on the ridge, or you can sow the wells according to the determined plant spacing. Each seed will sow 2~3 seeds, the sowing depth is 1.5~2 cm, and the soil will be covered 1~1.5 cm after sowing. 5500~6000 points. After sowing, pour the water in the ditch for 1 time, and then pour the water once after 2~3 days. The water volume should not exceed the ridge height, and the ridge back should be better.
After strengthening the field management seedlings, 3~4 pieces of true leaf time seedlings and seedlings were planted, leaving 1 plant per hole. The more summer radish grows short, it is generally not a seedling, it is necessary to promote the end. In the seedling stage, water should be poured to reduce the ground temperature, and the surface soil should be kept moist, but not flooding. During the growth period of fleshy roots, 0.2% urea solution can be sprayed on the leaves, sprayed once every 6 to 7 days, and sprayed 3 times. During the expansion period of the fleshy roots, the soil can be cultivated in combination with the planing. Before and after the planting of pests and diseases, in the plots and surrounding areas where radish is grown, it is necessary to strictly spray and cure phlegm and reduce the transmission of toxic media. Aphids and cabbage caterpillars can be sprayed with 2.5% kungfu emulsifiable concentrate or 2.5% enemy killing emulsifiable concentrate 1500~2000 times. Black rot can be controlled by agricultural streptomycin. When harvesting at a time when the weight of a single plant is 300~500, it will be harvested according to market conditions, but be careful not to harvest too late, otherwise it will be easy to heart and affect quality.
