Tillage, straw covering the whole potato cultivation technology
83; out with farming in the new Art Director Jiang Renhai saliva Chongming net, clean air, clean soil, and crab culture in the development of high quality rice production,[link widoczny dla zalogowanych], with unique advantages, the county area of 3 million mu of paddy field crab over. To further enhance the utilization of paddy land crab and comprehensive benefits, we have the sea in 2001, Xiang Hoy Hung Village, Chongming County 11 acres of rice paddy fields were crab technology demonstrations. Crab is the traditional paddy rice cultivation and aquaculture, a new combination of three-dimensional ecological agriculture, the use of rice in the shallow water, supported by artificial measures, not only rice, and crab farming, combine the two in the same ecological environment, the paddy fields of the water environment, insects and other materials and energy more fully into the crabs are used by breeding and life activities through the crab to the paddy fields weeding, cultivation, fertility purposes, so that from the paddy ecosystem structure and function can be reasonably used to make rice and crab symbiotic and mutually beneficial. A choice of plots and construction of 1.1 crab rice terraces choice should be selected close to the water source, water fresh, clean, good water retention areas, the area of each field is about 5 acres. 1.2 The trench-type groove design shaped by mouth design, wide 5m, bottom width 1.6m, slightly shallow inlet, the 1.0m, slightly deeper near the outlet for the 1.2m, 3m type design than the traditional channel �� 1m �� 1m widened significantly, this design not only easy to change the water, but also conducive to raising a large crab. Construction of facilities 1.3 Fangtao crab strong climbing ability, it must be built Fangtao facilities. Shop around farming ditch anti-crab to escape the hard plastic film and pest invasion, which buried 10em, height from ground 50em; paddy water inlet and outlet pre-embedded with cement culvert, culvert mouth fastened with a plastic mesh to prevent crab escape. 2.1 2 seeding rice cultivation management,[link widoczny dla zalogowanych], transplanting selected Naifei lodging resistance, stress resistance of high-quality hybrid Japonica Hanyou, on 10 May sowing, seedling age of about 30em. Straw is too thick, not only slow emergence, and the crown slender weak; straw too thin, leaving the green potato easily leaky rate. If the straw uneven thickness, uneven emergence occurs in the situation. The observed emergence neatly placed the straw is easy; the contrary, if the straw staggered winding, there will be Straw in the overlay tile when the Qimian not be left blank. If the horizontal direction along the line bedding straw, although straw can save, but close to the stretch of both sides of the tuber will see the light of the varying degrees by the pan-green, green potato production. After the straw covered with clean soil will ditch a number of straw pressure points to prevent the straw was a large wind chaos. After the plastic film mulching does not cover. Cold case cold when the plastic film to be sealed, but the cold after the film to be promptly thrown off. Pay particular attention to the straw covered evenly. If Qimian uneven thickness on the straw cover, resulting in uneven tuber. The shot,[link widoczny dla zalogowanych], the individual plant tuber Gallant little thinner, or even tuber, potato is green, and of quality. Should be strictly uniform coverage on the Qimian straw to improve the yield and quality. 3 water and fertilizer management every l0 days after bud 1 TA powder spray, and even spray 3 times, the foliage top dressing. Annual natural precipitation generally meet the requirements of this technology. However, the new straw absorbs less water, slow, easy to dry the potato seedlings affected by the drought. At the same time,[link widoczny dla zalogowanych], due to less rainfall in winter, after sowing by the amount of irrigation drainage ditch, keep the soil moist to ensure Miao Qi Miao, Zhuang, and timely water drying. To the growth of potato late decaying straw retention increased slightly, especially in the straw near the soil surface humidity, easy to dry, the growth of potato seedlings negative, so the encounter rain, especially when rain fell across the drainage ditch clearance in time, reduce field moisture, reducing the occurrence of late blight and other diseases. 4, the growth of insect pest control of potato late often encountered in the continuous rain the weather, the use of the technology, the straw cover, humidity field, in the above normal rainfall, weather conditions, special attention should be prevention and treatment of late blight. Planting of this period, above normal rainfall, humidity is too large, lack of attention to prevention and control of late blight, late blight serious, resulting in reduced production, production did not meet expectations. Should be in the budding period, the regular in-depth field investigation found the disease in a timely manner once the spray control. Covered with straw can suppress weed growth, no weeding. 5 harvest tillage, straw, the result of full coverage, so that the crown at the soil surface of the potato, from the most basal stolons grow along the soil surface extension of the soil encountered only a few cracks or pores and burrow into the ground. Therefore, in the harvest, you can pick poke straw collection. The growth in cracks or small pores in the tubers buried very shallow and easy to dig. Compared with conventional cultivation, potato round, fresh color, damage is low, greatly improve the value of the goods. Received Date :2003 -11-26-39 one country back
