First, the selection of fine varieties is one of the keys to high yields. The varieties that have been successfully tested in the local area should be selected for cultivation: Hybrid rice has Gangyou 364, Gangyou 527, Super rice Liangyou 2186, Hybrid rice Yixiang 101, and Shanyou 9. The conventional species include the Bo-selected series, 滇 449 449, 傣 406, and some japonica rice varieties.
Second, cultivating strong and prosperous sayings say "have a good half." The criteria for strong and strong are: 1 seedlings are healthy, dark green leaves. 2 The seedlings are dwarf and the base is thick and flat. 3 The root system is developed and the white root is thick and numerous. 4 grow evenly and neatly. 5 years of age and appropriate leaf age.
1. The selection of the sowing date, and the arrangement of the most sensitive period of rice growth to the most ideal period is the key to obtaining high yield. In general, early rice in our municipal district begins to be planted in late November in the first year of the year. Mid-season rice will be sown in late March in the first season, and late rice will be planted before July to obtain a safe and ideal harvest.
2. Seed treatment, seed use per acre, hybrid rice 1.5 to 2.0 kg, conventional rice 2.0 to 3.0 kg. Sowing before sowing for 2 days, then the seeds were disinfected by water, which was conducive to seed budding and seedlings. Selection can be selected by wind or mud. The selected seeds are separately soaked and germinated to prevent mutual influence. Sterilization Seeds can be treated with 1% right grey water or disinfectant with seeds.
3, soaking germination, early rice 48 hours, 24 hours in the rice, late rice can be 24 hours, requires changing the water 1 to 2 times a day, this can effectively prevent soaking sour taste and promote budding and neat. Germination should master the principle of “breaking the chest at high temperature (exposing whiteness) and adapting the root temperature to budsâ€. Early rice seeds are not easy to warm up and can be sprayed with warm water (40°C to 50°C) to promote rapid temperature rise. After the roots and buds are broken, they can be sown. It is better to plant seed buds and white seeds.
4. The ways of raising eel are dry seedlings breeding, small-arched film breeding (early rice), conventional water eel raising, floppy disk eel raising and plastic tray eel breeding. Dry cultivation and sparse planting is a successful technology. It was promoted on a large scale several years ago. However, most rural households have already alienated the way they educate themselves and have not achieved the desired results.
The operating procedure is: 10 m2 (net area) per mu of Datian field, 20 kg of farmhouse, 480 g, 255 g and 500 g of pure N, P and K. Turn into the seedbed and put the water into the bed. Face-to-face level, sowing 100 grams or 140 grams of wetted seeds per square meter, cover with fine soil until no seed can be seen. Seedling leaves are not watered when they are rolled and they can be transplanted 25 days after sowing. At present, the “Dry-Nanny†technology recommended by the National Agricultural Technology Promotion Center can be used to sow seeded seeds after soaking in wet grain or freshly emerged buds. Because it has ingredients such as fertilizers, medicines, strong stimulants and water retention agents, it is conducive to bred and strong.
The conventional water-raising program requires that the area ratio between Putian and Daejeon be 1:10.
Casting is a technology that saves the time and effort to save the seedlings and increase production. There are two kinds of techniques: plastic tray breeding and diskless breeding. There are differences in the way of childbirth, but the way of throwing seedlings is the same. A hole-in-place plastic tray must be seeded into the hole to prevent it from affecting the quality of the cast.
The floppy seedling machine insertion technology is currently an ideal choice for labor-deficit rice cultivation areas in the dam area. Machine insertion of 22 seedlings per acre (20cm40cm), plus 3 holes for seedlings for breeding seedlings, a total of 25 sets /mu. Only 4 to 5 square meters of land per Mu of Putian, with the role of saving money, saving time, labor and increase production. The way of raising seedlings is simple: use mud (preferably mud in the pond) to pour into the pan, evenly sow the treated seeds into the pan, and then put the seeds into the mud with bamboo or cover them with no-fat tillage. You can. However, in the rainy season, ventilation must be covered with a small arch shelter to prevent rain. The ditch around should be opened to prevent the flooding surface from affecting the quality of the seedlings. The seedlings can be taken out to 13cm to 15cm for machine insertion.
5, Putian management, seedlings grow up to a leaf to apply "weaning fertilizer" once, 3 kg per mu urea or 15:15:15 compound fertilizer 3 kg / mu watered. Dry seedlings or machine transplants should be applied sparingly. 5 days before transplanting, “send marrying manure†was applied once, and 3 kg of urea was used. Based on the occurrence of major diseases and insect pests in Daejeon, various localities have targeted the use of drugs in Putian to transplant them with drugs. This saves money and can also have a multiplier effect.
Third, transplanting
1. The whole field is ploughed according to conventional procedures. When the last field is completed, turn off the field water. Shi Jifei is based on the principle that “the combination of organic fertilizers and organic-inorganic fertilizers†accounts for 60% of the total fertilizer. Phosphate fertilizer must be used as the base fertilizer, and it is best to use rice as the base fertilizer. When Putian must adjust its water level, it must turn off the water and put the fertilizer in the field to prevent the outflow of fertilizer and water.
2. According to the characteristics of rice requiring fertilizer, use the results of soil testing and formula fertilization to fertilize the fertilizer according to the fertilization card recommendation scheme to increase the fertilizer utilization rate so as to reduce costs, increase fertilizer efficiency, increase production, increase income, and reduce environmental pollution.
3, rational dense planting, the general principle is that due to the long period of nutrient growth, early rice can be properly sparse, per acre planted 1.7 to 18,000 bundles / mu. Medium rice planted 20,000 bushes/mu, late rice planted 2.1 to 22,000 bushes/mu, both planted two plants. In the specific operation process, it should be based on the characteristics of the varieties (the strength of the tillers, the size of the panicles) and the good difference in paddy field fertility. The field is suitable for sparse planting, and if not, it is planted properly. Planting requires shallow, stable, straight. Small planting can achieve shallow planting, shallow planting can facilitate early birth and quick delivery, and it is easy to form multiple large spikes for high yield.
4, machine planting, with a special seedlings breeding seedlings, machine planting can be planted 2.0 to 2.5 acres per hour, the cost of 55 yuan / mu, a labor force a few minutes to take an acre seedlings, is a time-saving province and save money Successful technology, but the machine should check the size of the good spacing, to prevent the planting too thin and affect the yield.
5, Datian snails, with 1 kg per acre of Mildart, can effectively control the field of spiral pests, focusing on the nozzle and the field where the water layer.
Fourth, Daejeon Management
1, water slurry management, inch water to promote green, shallow water to promote delivery. Enough seedlings control ineffective delivery, control of cracking of the field, turn white root control seedlings only effect. In the booting stage and heading stage, irrigation is done, and the filling and maturation periods are dry, wet and wet, and mainly wet.
2, top-dressing, 5 to 7 days after planting, chase "sub-fertilizer", 7 kg of urea per mu, turn off the field water, and let it dry naturally. The jointing stage promotes “ear-fertilizer†to use 10 kg of urea per mu or 10 kg of compound fertilizer. After the full-fledged application of grain fertilizer once, 5 kg of urea per acre, and 50 g of potassium dihydrogen phosphate per acre, can effectively promote grain filling.
V. Integrated pest control The main diseases of rice include rice blast disease, bacterial leaf blight, and thin strip disease (the latter two are mainly on hybrid rice).
Rice blast, seedling shoots were sprayed with 45% sulphurazole 1200 times in Putian. Ye Xie sprayed 40% Chestnut Fuji 1,800 times, spraying once every 7 days. Panicle blast is one of the most important diseases affecting rice production in our city. The most effective measure to prevent and treat the disease is to spray with 75% tricyclazole WP at 1000 times every 7 days after 80% of panicles will break. Spraying once again can effectively control the occurrence of the disease.
Bacterial blight and thin strip disease occur mainly on hybrid rice. In the early stage of the outbreak, mu was sprayed with 10% Ye Huojing WP 2000 times or agricultural streptomycin 1000 times, spraying once every 7 days.
All pesticides should be sprayed on the same day or the next day after raining within 3-4 hours after spraying, so as to achieve the control effect.
Pest control, rice pests are mainly rice planthoppers and aphids. Rice planthoppers can be sprayed with 20% more than 1000 times solution of worm spirit or 10 grams of fipronil, and can not be killed by chrysanthemum lipids. Sanhuayu is sprayed with 25% of insecticidal double wettable powder 150ml spray or 200ml mixed sand. Cnaphalocrocis medinalis is a kind of pest with strong damage. Mu is sprayed with 1.0-1.5 kg of 2.5% trichlorfon powder or 50% of fenitrothion or 90% of trichlorfon crystals 1000 times.
6. Timely harvesting When rice is fully mature, harvesting can effectively maximize the collection of the product. Harvesting too early or late will affect the output of the product already waiting for production.
Second, cultivating strong and prosperous sayings say "have a good half." The criteria for strong and strong are: 1 seedlings are healthy, dark green leaves. 2 The seedlings are dwarf and the base is thick and flat. 3 The root system is developed and the white root is thick and numerous. 4 grow evenly and neatly. 5 years of age and appropriate leaf age.
