No-till paddy field covering rice straw
No-tillage rice fields covered with rice straw are more simple and convenient than traditional methods of cultivation, saving labor and reducing costs. First, the technical advantages 1, to reduce labor intensity: no-tillage rice fields, put the potatoes placed on the surface of the soil, covered with straw, potatoes grow on the surface of the soil, open the straw can be harvested, change the "seeds" to "put the potato "Changed from digging potatoes" to "picking potatoes," saving labor and energy, making it simple, reducing costs, and improving efficiency. Changed the traditional method of potato cultivation. 2. Increase the value of the commodity: The growth of the potato block is not affected by the hard clay block. The potato block is well rounded, even in growth, bright in color, avoids damage to the cut potatoes, and has good commercial properties. Straw covering inhibits the growth of weeds, improves the surface microclimate, and reduces pests and diseases. Basically, no straw chemicals are used, which is conducive to the production of pollution-free foods. 3, improve the soil, improve soil fertility: paddy, potato dry and dry rotation, to promote soil under aerobic conditions mature, improve soil structure. Straw and potato straw returning to farmland can realize comprehensive utilization of resources, improve soil fertility, protect the ecological environment, and facilitate the sustainable development of agricultural production. Second, the technical points 1, the selection of fertilization: choose loose fertile irrigation and drainage conditions of the cultivation of sandy loam. According to the ditching of 1.4 meters, the width of the surface is 1 meter, the width of the groove is 40 centimeters, and the depth is 30 centimeters. The soil dug during the ditching should be thrown evenly in the middle of the concrete. According to the paddy field fertility and yield requirements to apply base fertilizer once, do not top-fat. If the composting of the home-cooked fertilizer can be directly applied next to the seed potatoes, if the compound fertilizer is applied, the fertilizer will be placed in the middle of the two seed potatoes to prevent the bad seeds from being rotted. 2. Seed preparation: Use detoxified seed potatoes such as "Netherlands 15", generally 30-gram small potatoes for better sowing of whole potatoes, large potatoes should be cut into pieces, 1 to 2 shoots per cut, and the incision distance Bud eye at least 1 cm or more, spray 1000 ~ 1500 times liquid Ruizhi mildew, germination length of 1 cm or so. 3, sowing cover grass: North of Guangdong sowing in mid-December, to avoid the early heavy frost and late high temperature and humidity and other adverse climate. For each species of two lines, the buds are upward, the spacing between the rows and the spacing between the plants is 30 cm, and about 3,000 plants are planted per acre. Then spread evenly 8 to 9 centimeters thick soaked straw. The amount of dried straw used for mu is 750 kg. 4. Water Management: Natural precipitation has generally met the requirements of this technology. However, the new straw absorbs less water, is slower, and tends to dry, affecting seedlings and causing drought to the potato seedlings. It can be properly watered at an appropriate time, and the water layer should be shallow, with two-thirds of the ditch depth as the degree, and drained in time. The stability of straw rot in the later period is enhanced, especially the straw that is close to the soil surface has a high humidity and is not easy to dry. It is unfavorable to the growth of the potato seedlings, so it is necessary to pay attention to the drainage in case of rainy weather. 5, timely harvest: generally in mid-April potatoes have matured, you can pick out the straw. Under the premise of weighing production and market prices, it is also possible to harvest in stages, that is, to harvest the first growing potato chips, and then cover the straw so that the small potatoes continue to grow, so as to increase the yield and overall economic benefits. Third, pay attention to matters 1, to ensure that Miao celery seedlings: In conventional cultivation, potato seedlings are uneven and lack of seedlings phenomenon. The key to this technology is to strive for Miao Qi Miao Zhuang. First, choose the irrigation facilities of the field, irrigation is a necessary condition; Second, increase the germination level, according to the length of the seed sowing; Third, according to the provisions of grass cover, straw too thick, not only late emergence, and stem base slender and weak. If uneven thickness, it is more likely to cause uneven seedlings. 2. Prevent the production of sweet potatoes: The key to preventing the production of sweet potatoes is to prevent the straw layer from leaking light. First, when covering rice straw, it should be tiled across the entire surface of the crop. It must not be left empty. Second, the grass must not be too thin. The straw is too thin and easy to leak and the rate of sweet potato rises. The thickness of rice straw should be 8 to 9 cm.
