The selection of good varieties of radish in the off-season cultivation over the summer should use varieties that grow well, are crispy, sweet, and have fast root swelling at high temperatures. The suitable varieties include Lulu No.8 and Xiakang 40. Each of these two varieties weighs 0.5 to 1 kilogram, white and white meat, and can produce 3,000 to 4,000 kilograms of fresh radish per 1/15 hectare.
Timely Fertilization Site Preparation After harvesting, 5000 kg of organic fertilizer with good quality and 50 kg of compound fertilizer for vegetables are used as base fertilizer for every 1/15 ha. Grab ploughing, plowing 20 to 25 centimeters deep, squaring and ridging. The ridge distance is 55-60 centimeters, the ridge roof is 20 centimeters wide, the ridge height is 20 centimeters, and the length is less than 50 meters. The ridge is north-south.
Ensure that all seedlings are sown in late June. When planting, shallow trenches can be planted on the ridges, and can also be planted according to well-defined planting distances. Seeds of 2 to 3 seeds per hole are sown at a depth of 1.5 to 2 cm. After sowing, 1 to 1.5 cm of cover soil is planted, and every 1/15 hectare is planted. 5500~6000 points. After sowing, pour in small water in the furrows and pour water 1~3 days later. The amount of water should not exceed the ridge height, and it should be suitable for ridges and backs.
Strengthen field management After the seedlings are unearthed, 3 to 4 true leaves are seedlings and seedlings, leaving 1 seed per hole. The summer radish growing period is short, generally does not seedlings, to promote the end. During the seedling stage, water should be diligently grounded to keep the ground temperature down, and the topsoil should be kept moist, but do not flood with water. During the fleshy root growth stage, 0.2% urea solution can be sprayed on the leaves, sprayed once every 6 to 7 days, and sprayed three times. During the period of swelling of fleshy roots, soils can be cultivated in conjunction with ploughing. Before and after the prevention and control of pests and diseases, in the plots and surrounding areas where radishes are grown, strict treatment shall be used to control lice and reduce the transmission medium. Aphids and cabbage caterpillars can be sprayed with 2.5% kung fu emulsifiable concentrate or 2.5% emulsifiable concentrate for 1500-2000 times. Black rot can be controlled by agricultural streptomycin. When timely harvesting 300 to 500 per plant, according to market conditions continue to harvest, but attention can not be harvested too late, otherwise easy to worry about affect quality.
Anti-season (Summer) Cultivation Technique of Radish
Radishes are generally cultivated in the fall and are supplied to the market in winter. In recent years, the successful cultivation of over-summer products and the supply of products in the off-season not only satisfy the needs of consumers, but also enable the producers to obtain higher economic benefits.
