The paddy soil along the banks of the Lancang River is flat, fertile, sandy, rich in organic matter and various minerals. Organic matter, total nitrogen, alkali nitrogen, available phosphorus and available potassium are high, and total phosphorus and total potassium are low. . The soil has a large porosity and is suitable for the growth of crop roots. The soil is mainly planted with vegetables and peanuts, and is suitable for growing root vegetables such as radishes. Planting radish on gray-brown tidal mud requires the application of organic fertilizer, emphasizing the application of NPK fertilizer, the combination of bottom fertilizer and topdressing, and the topdressing should be a small number of times, so that the radish grows up in the early stage, and the medium term is stable, and the early stage is not premature aging. The purpose of increasing production and income. Radish is suitable for cultivation in sandy loam with deep soil layer, rich in organic matter, loose and fertile, strong water retention and fertility, and good drainage. The soil is thin, sticky, and gravel, which is prone to deformed roots and affects quality. 1 selection of soil preparation The radish varieties cultivated in the Lancang area currently have Korean radish Bai Yuchun and a doctor of disease resistance. Korean radish fleshy roots are long cylindrical, the quality is generally 1-1.5kg, the maximum can reach 2.5kg, and the flesh is white as jade. At the end of August, use a rotary tiller to plow 10-15 cm deep, and prepare the ground and sunburn to kill pest eggs and pathogen spores. At the beginning of September, 667m2 was applied with 2000kg of decomposed chicken manure. After cooling down, the nest was drilled with “rolling machineâ€, then one seed was spotted at each hole and finally covered with mulch. When germination, use a metal knife to punch holes in the film at the seeding site to facilitate emergence. 2 field management 1 cultivating and fertilizing radish should be shallow and shallow first, first and then far, until the closure after the closure. If there are weeds after the closure, it needs to be removed in time. In combination with cultivating and weeding, the soil is cultivated. In addition to cold protection, the radish plants can be prevented from lodging and the fleshy roots bent to improve the quality of the radish. In the middle and late period, the yellow leaves and diseased leaves are removed to facilitate ventilation and ventilation, and reduce pests. The area of ​​radish leaves is large, the roots are weak, and the drought tolerance is poor. Water should be watered in due course. Especially when roots are developed, water must be properly watered according to the growth conditions. The nitrogen required for radish seedling stage and leaf growth period is more than potassium and phosphorus; the growth stage of fleshy root is the accumulation period of nutrient storage, the demand for phosphorus and potassium fertilizer is increased, the potassium fertilizer is the most, and the method of staging is used for the first time. In the second true leaf, the second top dressing was in the late stage of the seedling, and the third time in the radish "breaking belly", the fourth time after the top dressing in the radish "outcrop", the grass ash or potash was applied once. 2 pests and diseases The main pests and diseases of radish are aphids, soft rot, virus diseases and so on. Through agricultural control methods, rational farming, rotation, early turning and drying, timely broadcast in time, avoiding high temperature, reducing disease, strengthening fertilizer and water management, and enhancing plant disease resistance. Timely control of pests and diseases. Aphids: 667m2 can be controlled with 10% imidacloprid 10-15g, 2% cockroach emulsifiable concentrate 50-70mL, 40% dimethoate emulsifiable concentrate or 50% cockroach emulsifiable concentrate. Viral disease: 10-20 mL of virus A (or other antiviral pesticides), 15 g of urea, and 15 kg of water can be sprayed. Miao disease collapsed: every 7m10 every 20m with 20% hundred smoky tobacco 0.2-0.3g smoked smoke control, the next day. Soft rot: Control with 70% dikesone 800 times solution or 50% dexamethasone 600-800 times solution. 3 timely harvest, single quality 1.5-2kg, harvested from late August to February next year, 667m2 radish yield 4-5t. 3 conclusions There are many years of experience in planting vegetables along the banks of the Lancang River. In the Hanjiang area of ​​Chongqing, in the cold dew (October 8 or 9) to the frost (October 23 or 24), the soil, fertilization, film mulching, and on-demand radish seeds were Radish live growth, before the winter solstice (December 21-23) to grow strong seedling period, Xiaohan (January 5-7) when the radish is listed, the commodity rate is high, the radish leaves cultivated in the open field are thick green, strong photosynthesis The radish has long roots, is crisp and nutritious.
