How to cultivate organic rice to grow organic rice? Summer is coming, and the rice growing season is now. Organic food is a relatively unified way for non-polluting natural foods in the world. Because organic foods are healthy and delicious, they can avoid some diseases and contain less chemicals. . Therefore, organic rice is the development direction of rice production in the future. Therefore, in cultivation technology, it is necessary to work hard and make efforts. Fertilization, seed selection, sowing time, and irrigation during the cultivation process are not good for me, and it has become a difficult problem for cultivation.
1. Rational fertilization to ensure supply. Organic rice can only be applied with organic fertilizer, preferably cake fertilizer, chicken manure (but must be decomposed, fermented), etc., can not apply fertilizer, the base fertilizer should be high quality and sufficient, can apply 2000 kg of fermented chicken manure per acre, Apply evenly, can not pile up, so as not to burn seedlings, topdressing should eat less meals, mainly to pursue high-quality farmhouse fine fertilizer, it is best to pursue cake fertilizer.
2. Choose excellent species and highlight excellent characters. For the seeds of organic rice, it is necessary to select good varieties with good stress resistance (mainly resistance to pests and diseases), strong tillering power, partial large ears, eutrophication, good commercial quality, high-quality rice, suitable for dry seedling cultivation and ultra-thin planting mode. The germination rate is above 95%, and the purity and purity are over 99%. It can not be planted in the area, ensuring that it is fully matured 5 to 7 days before the frost, so that it can be properly matched in the early, middle and late, and the seeds of the seeds can be fully utilized. Do your best. Seed treatment before sowing to ensure a seedling preservation seedling.
4, clean water irrigation, scientific water. Organic rice should be irrigated with clean water. It cannot be filled with domestic sewage or industrial water. It should be single-row irrigation. The specific method is: flowering water during transplanting, 2~3 cm water layer after greening, effective shallowing before tillering, improving ground and water temperature, promoting tillering, effective tillering at the end, on the growing lush land, immediately draining the field 7 to 10 days, the control is not effective, the degree of drying the field reaches the whitish surface, the ground has cracks, the white surface of the pool surface, the leaves are faded and straight, and the root system is promoted. After draining the fields, take dry, wet and dry intermittent irrigation to protect the roots and roots. In addition, the organic rice should be selected from plots with good water source conditions, not thirsty, and can not be irrigated with well water. There is no way to set up a sunbathing pool to raise the water temperature. (Jin Tao)
3, grab the early catch, early broadcast in due course. When the temperature is stable at 5 °C, it can be sown, 1~2 accumulated temperature belt will be seeded in early April, 3~4 accumulated temperature belt will be seeded on April 15th, seeding will be planted before the end of April, infertile May seedling, seedling adopting greenhouse cultivating or钵 Sports seedlings, do everything possible to cultivate strong. When the temperature is stable at 13 °C, the transplanting is started, and the transplanting method of ultra-thin planting is adopted. If the temperature is not inserted in June, the quality of the transplanting is improved, and the side is smashed, inserted, smashed, inserted, straightened, inserted, and inserted. Reasonable close planting, found that the lack of seedlings and empty areas, to transplant seedlings to replant.
