High-yielding cultivation techniques

High-yielding cultivation techniques

First, avoid re-planting in three years, not to plant pods and celery on the block to prevent the occurrence of plant rot (also known as dead seedlings or dead worms) and other soil-borne diseases. Second, the seed treatment to split the seeds, use 15 °C -20 °C water soaking 12-24 hours (in the middle of a replacement of water), remove and control the excess water, a little air, into a wet cloth bag, each bag About 0.5 kg is put into the pit and germinated. In the cold season, germination occurs. Dig pits in sheds or in areas where there is no frost. The pit is 30-40 cm deep and 25-35 cm long and wide. The bottom of the pit is covered with a 6-7 cm thick layer of wheatgrass. The wet cloth bag with the seeds is placed in the pit and covered with a layer of soft grass. The plastic cover is used to cover the pit and the grass is covered with shade. . During the germination process, the seeds are removed daily and rinsed once with warm water of 10°C-20°C. Can also be used 5ppm gibberellin (85% gibberellin 1g water to 170 kg) or 1.8% high yield factor (love more, altogether nitrophenols) to 6000 times the water, soaking seeds for 12-14 hours, instead of low temperature soaking And germination within the pit. Third, organic fertilizer, phosphorus fertilizer as the base fertilizer application of organic fertilizer to be fully fermented and decomposed and finely crushed, the application of phosphorus fertilizer is quick, generally 8000 kg of organic fertilizer applied in Mushi, 75 kg of DAP. Fourth, sowing and sowing, sowing the amount of appropriate fertilization after turning 2-3 times, so that the soil is mixed evenly, smashing smashing litter, smashing smashing the surface, then smashing smashing surface, pouring sole water, water seepage immediately after Sow seeds. In order to make water every day after sowing without silt shoots, cover 0.5 to 0.8 cm thick fine sand after sowing. To adopt the screen cover sand method, that is, with a 4-16 mesh iron screen on the surface of the swing, the fine sand sieve falling, evenly covering the surface. The amount of mu for use is about 1.5 kg. The fast-growing seedlings must be planted densely when they are put on the market. Three to four days after the emergence of seedlings, a small amount of water is poured and poured. To raise seedlings in protective facilities during the cold season, it is necessary to prevent the high temperature on sunny days and sprinkle water once a day. 5. 48% trifluralin (solanum koning) EC 50g/mu, water 50kg or 25% Liguron EC 100g/mu or 50% Ligulon WP before sowing herbicide 60 g/mu, 50 kg of water, evenly sprayed on the surface, and keep the surface wet. After the seedlings can be used, mu can be sprayed with 50% paracetamol WP and 50 g water 50 kg. 6. Strengthen field management Temperature adjustment. The temperature limit for seedling growth is 3°C-20°C and 12°C-15°C. 2. Water management.芫荽 芫荽 芫荽 芫荽 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝 涝. 3. Timely seedlings between the seedlings. After the seedlings emerged between the seedlings; two true leaf stage Dingmiao; seedlings from 3-4 cm. 4. Fertilize early and apply nitrogen fertilizers quickly. When the seedling height is 2 centimeters, topdressing is started and it is advisable to flush with the available nitrogen fertilizer. Usually 8-10 days, once the water is poured, every time the water is applied for one chemical fertilization, each application of potassium nitrate 15 kg (or urea 10 kg) and borax 0.25 kg. The late fertilization fertilizer should be formulated with nitrogen and potassium. Each time, urea and potassium sulphate can be applied in an amount of 8-10 kg. 5. Chemical control. In the first half of harvest, 20-25 ppm of gibberellin should be sprayed and the yield should be increased. VII. Prevention and control of pests and diseases Prevention and control of early plague, late blight killer, green copper, benomyl, etc., prevention and control of sclerotinia, gray mold with lingoliling, sclerotin, etc., prevention of soft rot with DT, CT, etc. , Virus disease bacteria poisoning, disease control and other diseases, prevention and control of plant rot with copper master, vegetable g bacteria prevention and control, aphids, whitefly, spotted with the imidacloprid, imidacloprid, A Wei insect clear and other prevention.
