Dry film mulching cultivation of direct seeding cultivation techniques, is the non-woven coating technology innovation and development. In addition to inheriting the advantages of water-saving, fertilizer-saving, precocious, high-yielding and other advantages of the original rice mulching cultivation technology, this technology also has such prominent advantages as simpleness, labor saving, production increase and efficiency increase.

Use of rice film mulching direct seeding cultivation, we must choose a convenient irrigation, good water retention of rice fields, with the best early cropland yield. Water is not guaranteed, can not be irrigated paddy fields should not be the use of the technology.

As the accumulated temperature increases after rice membrane cover, the maturation is earlier. In order to give full play to the effect of increasing the temperature and increasing yield of the cover film, the hybrid combination with longer growth period and large yield potential should be adopted.

The whole field of water without technology, dry and dry to take. Before the whole field, 2,000 kg of high-quality farm fertilizer is applied to the area and then deep-deep-plowing it. Then 50 kg of compound fertilizer and 10 kg of urea are evenly spread, and then the surface of the field will be raked horizontally to mix the soil with the fertilizer. After the field is completed, a ditch with a width of 2.0 meters starts to be ditched. The net carriage is 1.7 meters in width and 30 cm in width, 20 centimeters deep. Vanishing topsoil as flattening, Kela with iron teeth grilled into the ditch (side with the film), at the same time around a good ditch around.

Select 1.7 meters wide paddy special super-micro-film, while soil moisture suitable car spray spray chemical herbicide (underground pests but also the first drug pest control), and then cover the plastic film. Cover the film, pay attention to the film as far as possible with the car side close, paved, with the film side of the Kela and fine soil sealed and solid, to prevent running temperature entropy. At the same time in the film to clean the car ditch.

The use of non-woven fabric (size 80-100 g / m2) + plastic film coverage, the crop growth in the general temperature can be maintained above 8 ℃, the middle and lower reaches of the Yangtze River harvest of tomatoes, eggplant, peppers, cucumber, etc. Anti-season vegetables. Specific methods: surface with plastic film, the trench covered with straw, and then according to melon, eggplant and other vegetable plants in the shed to take the shed or shed, the evening to cover a layer of non-woven fabric, and then covered with a thin film, or First cover the film, then covered with non-woven.

Winter outdoor minimum temperature 0 to -2 ℃, small, in the shed at least to maintain more than 8 ℃. If you encounter a special cold, you can add a layer of non-woven fabric and a layer of film above, even if the outdoor temperature dropped to below -5 ℃, the small shed can still be maintained at 5 ℃ above, so the use of this Method of insulation, can make the winter winter in the greenhouse tomato, eggplant and other warm vegetables can grow and the normal results, and obtain good economic benefits.
