“Liu Webmaster, I have planted a crop of my life. I have never heard of any kind of rice planted in the paddy field. How would such a kind of rice look like?†On March 20, when I came to Letai Village, Changchi Town At the same time, villager Cheng Zhengxing looked at two women who were covering the film in the paddy fields and asked me questioningly. “This is called rice film mulching cultivation. It has water storage and heat preservation, warming and heat preservation, defense against low temperature and cold damage, reduce weeds and pests and diseases, promote low-level tillers, prolong vegetative growth, prevent soil erosion, reduce soil nutrient loss, maintain soil looseness, and improve The comprehensive effects of fertilizing and supplying fertilizers, alleviating seasons, saving labor intensity, and increasing production and income increase.†I patiently explained that through the demonstration of Jianhua Village in Changchi Town last year, it was shown that the whole rice film cultivation of rice is not only different from that of ordinary rice. Irrigation water covered by rice mulch can save more than 40% of water compared to conventional planting methods, and it can also produce more than 180 kilograms of rice per acre. During the operation, pay attention to the following 7 key technology suitable varieties. Choose a variety that is slightly longer than the average growth period of rice to achieve the potential for increased yield of coated rice. Such as "Dexiang 4103" and "Gangyou 364" hybrid rice varieties. Dry seedlings. The use of floppy-covered dry membranes or dryland mulching for dryland education was implemented, while the seedbed temperature and humidity, pest and weed management, and mulch care were strengthened. Fertilizer base. Based on the application of organic fertilizer, Mu uses 10 kg of rice field biological treasure, with 5 to 10 kg of compound fertilizer and 1-1.5 kg of zinc fertilizer as the base fertilizer. Dissolve the phoxim granules in the car. The heavier plots of the weeds, 2 to 3 days before filming, were treated with a selective herbicide such as butylbenzene for soil closure. Trenching cover film. The winter rice field cuts the grain piles and carries out no-tillage cultivation. After the two crops are farmed with shallow water, the fertilizer and the herbicide and insecticide are applied, the back cover film is opened by 5 feet wide and the plastic film is selected to degrade the ultra-micro film, and the covering film is: Membrane solid, membrane strict, membrane straight. Punching and dislocation planting. After the film is covered, press the "3" seedling spacing, 10" spacing, and 13.5" spacing to make measurements. Each row of 5 nests, each hole three holes, 4400 nests per acre. The two-leaf rice was planted with two leaves per hole. Implement water-saving irrigation. The key irrigation periods are transplanting period, booting heading and milk ripening period. In the transplanting period, the soil moisture content should meet the criterion of the maximum water holding capacity in the field, wet irrigation should be carried out, and the semi-guttering water at the booting stage and the heading stage should be sufficient, and the milk ripening stage should be kept dry, wet and dry. Implement comprehensive prevention and control. Covered with plastic film, rice film can suppress weeds. At the same time, the fields are light and airy, the humidity is low, and the damage of pests and weeds is significantly reduced.
