The full coverage of rice mulching with warming and moisturizing techniques (abbreviated as plastic rice) is a major invention in our county. Rice mulch film covering dry and direct-seeding cultivation techniques is the innovation and development of "mulching rice" technology. In addition to inheriting the advantages of water conservation, fertilizer conservation, early maturity, and high yield of the original rice plastic film mulching cultivation technology, the technology also has the outstanding advantages of simple, labor saving, productivity increase, and efficiency improvement. The technical points are as follows: 1. Select suitable fields. In order to use rice mulch to cover dry and direct seeding cultivation, paddy fields with convenient irrigation and good water retention performance must be selected. Water sources are not guaranteed and paddy fields that cannot be flooded at any time should not use this technology. 2, using good varieties. Since the accumulated temperature after rice mulching increases and matures earlier, in order to fully exert the effect of increasing temperature and production of mulching film, a hybrid combination with a longer growth period and a greater potential for yield increase should be used. 3, Shizu base fertilizer, specifications box. This technology does not use water for the whole field and takes dry and dry seeds. Before the whole field, apply 2000 kg of high-quality farmyard manure, and then deep-dip it again. Spread 50 kg of compound fertilizer and 10 kg of urea evenly. Then spread the surface of the field as evenly as possible to mix the soil and fertilizer. After the field was well formed, the ditch was lifted by a 2.0-meter wide line. The width of the car was 1.7 meters wide, and the width of the car was 30 centimeters deep and 20 centimeters deep. The top surface of the car surface should be leveled and crushed as far as possible, and then the metal teeth should be pulled into the ditch with the iron teeth (used on the lamination film side), and the ditch around the ditch should be opened. 4, timely cover film, drilling sowing. Select 1.7 meters wide rice field special strong superfine membrane, when the soil is suitable for the plane spray chemical herbicide (have underground pests but also first sprinkle insecticide), and then cover the film. When the film is covered, the film should be tightly adhered and flattened as far as possible, and the film edges should be tightly sealed and covered with fine soil to prevent running away. At the same time clean up the compartment at the membrane edge. After the cover film is punched and sown. It is best to use a hole puncher with a wooden stake at the bottom of the board to drill a hole with a spacing of 30 cm (6 rows per hole), a 15-18 cm spacing, and an aperture and hole depth of about 2 cm. Three to four seeds of just-broken rice seeds were sown in each hole. After sowing, the seed was tightly covered with fine soil and sealed at the same time. The sowing time can be about 10 days earlier than ordinary paddy fields. 5, moist emergence, dry and wet alternate management. After sowing of rice, irrigation flooded the surface of the car, and at the same time twisted the field side (to prevent large water seepage from the field side), let the car surface water naturally dry, keep the car ditch water, wet the car surface soil, promote rice early emergence, early seedlings . After the rice is seedlings, fill it with thin water to promote it. After the rice is sufficiently seedling, it can be sun-dried, sun-baked, light-stained and diligently sun-dried as early as possible to prevent excessive ineffective delivery. In the later period of rice growth, the main management is wetness. In addition to filling the water during the key water-requiring period such as shank rod jointing, heading and flowering, the water is kept in the ditch at other times, and the car surface is wet. 6, see Miao fertilizer, foliar spray fertilizer. During the jointing stage of rice stems, the seedlings were treated with appropriate amounts of urea in combination with irrigation. Spread the fertilizer on the surface of the car and submerge the membrane surface while tightening the gap, so that the fertilizer can infiltrate into the pores of the film with water. Rice breakage combined with pest control, foliar spray fertilizer 1 - 2 times. 7, Qi harvest, no-till transplanted rape. For dry-land rice film in the dry season, we should try not to step on the surface during the management process to maintain the integrity of the plastic film. After the rice matures, the mud is harvested and the transplanting rape is directly punched on the old membrane.
