High yield and efficient cultivation techniques of spring radish
The Yangtze River valley is suitable for spring radish variety cultivation. Its quality is good. The sowing date and cultivation method are flexible. The product growth period is only about 60 days. The market for supplementing the market from March to June the following year is spring, and the yield can reach 5000-6000kg/mu. The benefits are generally good. Above 800 yuan/mu. In recent years, it has become a popular choice for professional farmers, and it is also one of the excellent autumn and winter agricultural development projects in the plains. First, varieties and sowing date selection Spring radish must choose winter strong, low-temperature growth, good quality, disease-resistant varieties, try to reduce the risk of early moss. According to the author's recent demonstrations, Shinong 2000, Shinong YR1010, Chunbai Wang, Bai Yuchun and other varieties have excellent comprehensive traits and are relatively safe choices. The sowing date can be set according to the production level and actual demand of vegetable farmers. Generally, professional farmers should choose sowing in 12-2 months, implement greenhouses plus small sheds and mulch "three membranes cultivation" or greenhouses and mulch "two membranes" cultivation; plain farms should choose From February to April, small arch shelters added mulch cultivation or plastic film cultivation; in early April, they can also be cultivated in open field, but they are late for market and low in yield. The second highest mountain can be sown in April-June. Second, fine soil preparation work, application of base fertilizer spring radish growth period is short, high yield, need more fertilizer and concentrated, so fine soil preparation and base fertilizer is very important. Choose sandy soil or sandy land for planting, soak 2-3 times deep before sowing, and plowing at a depth of no less than 20cm, and turn up the soil and pick up field rocks and rubble. At the last time when the ground was turned, 3000kg of manure and 3000kg of compound fertilizer were used as base fertilizer. Generally, 1 m for ditch is used for the ditch, which is 0.65m in width, and the turtle is in the shape of a turtle; the ditch is 0.35m in width and digs a 50cm deep ditch every 30m, and the ditch is 60-70cm deep. Sangou high standard facilities to prevent waterlogging in the field. Third, the precise amount of sowing, reasonable and dense planting in order to reduce costs and avoid rooting, spring radish generally use precision amount sowing. Two rows of each sowing, spacing 0.35m, hole spacing 0.20m, wide row spacing 0.65m, sowing 1-2 tablets per hole. Before the sowing, the footing water was poured and the pre-herbicide herbicide was sprayed. More than 6,500 holes per mu, about 8000 basic seedlings, 75-90g per acre, to avoid too little seeding and direct sunlight to produce a blue head. Fourth, timely film rupture seedlings, seedlings, seedlings after sowing 10 days after sowing, radish cotyledons to be timely when the membrane ruptured seedlings, with a knife or bamboo stick on the film draw a "10" shaped opening, immediately after release radish seedlings Sealed with fine soil to prevent the heat in the membrane from dying. 3-4 true leaves with time-shifted seedlings to fill the gap, the excess seedlings will be transplanted to the hole, to ensure a strong seed per hole, no heavy seedlings lack seedlings. In open field sowing or plastic film cultivation, small sheds should be used to partially use seedlings for supplementary planting in the event of seedling deficiency. V. Fertilizer Management and Pest Control Spring radish should be watered as little as possible after sowing, and small water skewers should be used when blanched whitish, avoid frequent water supply and flooding, and rainy season and high groundwater level. The area should do a clean ditch drainage work; when thinning with human fecal urine plus 2% urea topdressing; sowing about 30 days, when the radish bare shoulder mu with ternary compound fertilizer 15kg water concentration of 1% pouring, after sowing, Forty-five days of fleshy root enlargement mu with 20kg compound fertilizer applied to the water, with the surface see dry see wet as well, when the soil moisture is high, the fertilizer can be applied at 10cm from the root; fertilizer and water supply will be stopped one week before harvest. The occurrence of diseases is related to the resistance and continuous cropping of varieties. When selecting disease-resistant varieties, it is necessary to avoid continuous cropping with cruciferous crops; to keep the field dry and to focus on agricultural control; to use the control of pesticides at the initial stage of disease, such as anti-virus aphids, Can kill and so on. Insect pests mainly control aphids, cabbage caterpillars, diamondback moth, and beetles. Imidacloprids, pyrethroids, and biopesticides were used to alter spray and kill. In addition, the spring radish should pay attention to the combination of Qinggou high soil, combined with soil to prevent weeds. 6. Harvested spring radish can be harvested according to market conditions in advance or after 10 days, harvesting radish cherry 3-5cm to extend storage time. Do not wash long distance sales.
