Radish is a high-yield crop with strong adaptability, few diseases and pests, high yield, and wide use. With the effect of health care and nutrition, it can be used as a variety of cooking foods and is favored by consumers. The late autumn of our province is rich in light and heat resources, and there are many places in the fall and fall. It can grow autumn radish in large quantities. Planting autumn radish can harvest 2500-3000 kilograms of radish per acre, and the economic income can reach 1,000-1,500 yuan. It is a good way to benefit farmers and it is a good way for farmers to increase income. The key technologies for the cultivation of autumn radish are as follows: 1. Planting area: Select soil (including ph, cadmium, lead, mercury, arsenic, chromium, hexachlorobiphenyl, and DDT), water quality (including pH, cadmium, lead, mercury, fluorine, Arsenic, hexakis-phenol chromium, cyanide, chloride, and the atmosphere (nitrogen oxides, sulfur dioxide, and fluoride) are all in accordance with the requirements of the "Pollution-free agricultural products - production environment standards". Second, the selection of varieties: planting autumn radish should use medium-term growth, high yield, strong resistance, good quality and good varieties. Such as: horse ear early, red root radish, round root radish and other varieties. Third, the preparation of soil sowing: Autumn radish should be selected to facilitate irrigation and drainage, loose fertile land cultivation. The autumn radish planted on the paddy field should be cut off immediately after the rice is harvested, dig 25 to 30 centimeters deep, and properly manage the surrounding drains, requiring the main ditch to be 45 to 50 centimeters deep and the side ditch to be about 40 centimeters. After the late spring crops are harvested, the autumn radish is planted immediately after harvesting. Mushi requires 3,000 to 5,000 kilograms of organic manure and 200 kilograms of plant ash. After fertilization, it should be ploughed into the soil and fully mixed with the topsoil before sowing. According to the row spacing of 33 cm and the spacing of 20-25 cm, 7-8 grains per hole were sown and fine soil was covered after sowing. Four, field management: 1. And time seedlings, Dingmiao: the seedlings grow to the cotyledon fully when the first time the seedlings, grow to three true leaves when the second time the seedlings, grow to four true leaves when the last time the seedlings It can be set later. The planting density is 800 plants per acre, and the planting density of large plants can be appropriately diluted. 2. Watering: The leaf grows normally and does not water when it grows. After entering the flood season, sufficient water should be supplied and watering should be stopped one week before harvest. In the rainy season, attention should be paid to timely drainage. 3. Fertilization: After the first seedlings, the first topdressing will be applied. Mushi ammonium sulfate will be 7~10kg; the second time of the lotus stage will be topdressing, and the Mushi Sanyuan compound fertilizer will be 10~15kg. It can also be used to clear manure water per acre. 15 to 18 tons. In addition, a 0.3% borax solution should be sprayed on the leaves during the root enlargement to promote its growth. Autumn radish dressing should pay attention to two points: 1 the amount of nitrogen fertilizer to be applied, too much nitrogen fertilizer is likely to cause radish with bitter taste; 2 each time after top dressing to be poured with water to accelerate radish growth. V. Pest Control: From the seedling stage, use 40% dimethoate 800-1000 times, or 20% Methomyl 1500-2000 Diluent, or 2.5% Diurec Emulsion 3000 times spray to prevent aphids and yellow Flea kicks, cabbage caterpillars, etc. In the later period, 75% chlorothalonil 600 times solution or 65% zeocin zinc 500 times solution was sprayed to prevent downy mildew; with 50% dexamethasone 800 times, or 47% garenone 500 times, or 50% Can kill 500 times liquid spray to prevent soft rot.
