Chunwang radish is native to Korea and is the latest generation of spring radish varieties. With root-shaped straight, beautiful white, strong resistance to cold and strong twitching, seeds are small, with the characteristics of species. After many trials in our province, it is generally reported that it is a rare good variety of spring radish. This article describes the cultivation techniques under mulching. First, the planting of the Yangtze River basin can be planted from September to April, and the anti-season planting in high mountains in our province can be planted from May to August. Seed sowing from December to January, with a plastic film or plastic film covered with a small arch cover cultivation, open field can also be planted, but the yield is lower than the cover cultivation. Other time sowing, plastic film can cover the cultivation method. Second, the site preparation of Qichunwang radish is a large-scale, high-yielding spring radish variety with a short growing period. It is best to choose a deep, fertile plot of land with fine cultivation and sufficient base fertilizer. Plowing no less than three times, the depth of arable land more than 20 cm. The base fertilizer should be applied on the last arable land. Mushi rot is 2000 kg of manure or 50 kg of cake fertilizer, 35 kg of ternary compound fertilizer, and mix thoroughly. According to the soil moisture situation in time. For specifications: 80 cm open, full width 55 cm wide, 25 cm wide stilts, the surface slightly turtle shape. Every 30 meters long open a ditch, in the field to open a good ditch, in order to facilitate irrigation. Third, sowing method is generally used on demand, sowing each one, plant spacing 2550 cm. IV. Seedling management After sowing, the radish cotyledon flattening should be performed to break the film, seedlings, and make up seedlings. Should be noted: First, the plastic film break should not be too large, as long as the seedlings can be exposed, and then grab a small amount of fine soil will be sealed plastic film break. Second, there is a large temperature difference between the inside and outside of the mulching film on sunny days, and hot air flow is easily generated at the breakage. In this case, the emergence of plastic film on the seedlings can make the water metabolism of the seedlings unbalanced and wilting. Therefore, the film-breaking seedlings should be carried out on cloudy or noon days. Fifth, water and fertilizer management Spring planting generally does not lack water, should pay attention to the field of waterlogging, reduce soil moisture. The lack of water will reduce the yield and quality. If there is a whitening crack in the gutter, it should be fed with horse water. Timely dressing, so that the radish in the mid-late growth process has enough nutrient absorption, is divided into two: 30 days after sowing, most of the radish strapless chase the first time fertilizer, mu compound fertilizer 25 kg turned into 0. The 5% liquid fertilizer was used to irrigate the roots. The second fertilization was carried out about 45 days after sowing. The amount was the same for the first time. Humidity of the soil is large, and the top dressing can be applied with a hole or a gun, 10 cm away from the root of the radish, and two top dressings are applied at different positions. VI. Pest Control The main pests of spring radish are yellow striped hop and aphids. They are sprayed on the leaf back with 1000-fold dichlorvos and 1000-fold dimethoate, and are also available for pyrethroid pesticides. Spring radish may also be a disease, mainly downy mildew, with agricultural control method is clear drain ditch, not flooding. Metalaxyl can be used for chemical control, but it can be used interchangeably with mancozeb. The soil moisture is high, the weeds grow faster in the mulch, and sometimes it can damage the grass by damaging the mulching film. The squeezing of the soil in the trenches will make the weeds dead. VII. Harvesting General crops can be harvested in about 60 days (relatively longer growing season in the cold season). The temperature in March and April will rise and it will be harvested in about 50 days after sowing. Harvest radish cherry 3 cm when harvesting, wash the nearest supply, the long-distance sale should not be cleaned.
