A standard. For long-bud rice varieties, it is required that the length of rice seed buds should reach more than half of the grain length of rice seeds. Two advantages. Long bud rice live broadcast is beneficial to: 1 reduce rotten species. Especially for seeds that fall into the unfilled potholes, the chance of rotten seeds is greater; 2 is conducive to rapid emergence. The germinated rice seeds reduce the time of water swelling and germination in rice fields, which is beneficial to early emergence; 3 reduce the lack of seedlings in the graves or flooded areas, and fall into the graves or floods according to the principle of long roots and long roots The rice buds in the area can also grow in the largest part, laying a foundation for Miao Qi Miao. Three technical points. 1 drying seeds. If the seeds are not coated before the seeds are soaked, they should be sun-dried, and they should be sun-dried for 1-2 days; According to the type of rice varieties, choose to soak for 1-2 days, wait until the rice seeds are inflated and drain; 3 germination. Use the basin to pack the seeds, cover with a warm towel, place warm water in the pot, place in warm water, and cover the lid. Take it out before cooking, and then put it in after cooking. When the rice buds are more than 50% longer than the rice granules, they are taken out for use. 3 The whole field is opened. At the time of drying, start to plow the winter leisure field, and after two years of ploughing, open the car, and ask for the flat surface of the car, let the water surface dry, so that the car surface is waterless, and there is water in the ditch. Because Linshui County is located in the hilly area, the slope of the Tianxiao block is large, and it is difficult to do it absolutely; 4 mixed herbs and cooked valleys; rice seeds of direct seeding rice fields must be mixed with bird-killing drugs, 10 grams per kilogram of dried rice seeds. The proportion of 35% butyl thiocarbamate is used for seed dressing, and the mixture of butyl thiocarbazone and long bud rice seeds is vigorously shaken by a container, and it is not easy to create by hand, which is easy to cause damage to rice buds. After mixing well, mix the cooked rice and cook it 1-2 times again and shake it evenly to prepare for seeding; 5 sowing. The prepared rice seeds will be uniformly sown according to 1-1.25 kg per mu of paddy fields, first planted 70%, and the remaining part will be re-suppleed twice to ensure uniform seeding; 6 reasonable fertilization. Before the whole field, according to the planned production requirements, more than 30 kg of rice special compound fertilizer should be applied per mu, and evenly spread into the paddy field for the paddy field, and then the whole field should be carried out. When the rice seedlings are more than 3 leaves, the seedlings are applied with more than 5 kg of urea per acre as the tillering fertilizer, and the seedlings at the heading stage are applied to the grain fertilizer; 7 comprehensive prevention and control. The first is the prevention and control of pests in Daejeon. In the first half of May, the rice seedlings were sprayed with 30% of the chlorpyrifos 70 ml or 30% trichlorfon, chlorpyrifos 30 ml and 50 kg of water to control the rice mites. Others should pay attention to the control of rice mites and leaf mites. Main rice pests and diseases such as sheath blight, rice blast, and rice planthopper; The second is weed control. For the weeds, the field was treated with a herbicide such as paraquat in the first half of the field. The acetochlor series was used for control 2-3 days after sowing. In the case of rice seedlings 2-3 leaves, according to the situation of rice field weeds can be controlled by the time of the farm; etc.; 8 field management. The direct seeding field of rice has strict requirements on water, and it is made to be wet in the field before the seedling is planted. 3-4 leaf field irrigation to prevent weed growth, shallow water retention during the jointing stage, drainage control in the late tillering stage, and water management requirements of deep water in the later stage.
