Lotus car covered for warming water planting technology


Row of lotus 1 per hole,[link widoczny dla zalogowanych], size grading, was 5) The tightly covered. Row of lotus root is completed, smooth hand side, tightly covered. 4.3 The scientific management field 1) water management. Water Management in the whole growth period according to the When the leaves cover the whole field, the film gradually lose the warming function and membrane surface can be maintained 10 ~ 15cm water layer. In case of lotus growing season rain, water flooded Fourier, immediately drain. 2) top-dressing fertilizer generally twice, once in the five full leaves, top dressing, 75 ha of urea, or human waste 150 ~ 300kg. Each thin layer of top dressing first irrigation water, manure natural to let the water after drying,[link widoczny dla zalogowanych], to the lotus stems, leaves no drops of water when the surface to avoid fertilizer burn on a Summer Day in the leaf blade. 3) disease prevention. Lotus root rot and leaf spot disease mainly. Root rot usually originating in early May. In mid-July to early August Sheng. To early prevention, timely removal after the onset of strain, 50% WP Carbendazim 75% increase 600 times 600 times chlorothalonil WP dubbed mixture, sprayed on the ground petiole, leaf to brown spot in the early onset of disease with 50% of the carbendazim spray administration of 600 times, while paying attention to increasing phosphorus, potassium, calcium. 4) pest control. Dimethoate 40% available from 1500 to 2000 times, 2500 times or the destruction of brush spraying aphids interest, while paying attention to prevention and treatment of S. litura and other pests. 5) herbicides. On the ridge around Amoy, the car side to the top of the film's timely removal of weeds. Lotus 44 mature and no significant harvest maturity, . 5 Discussion 5.1 The prospects for the development lotus is the 'kind of high yield crops, market prospects, the enthusiasm of farmers to plant lotus root is very high. As the film to promote the use of car for the technology will be growing region in the lotus root, and theoretical aspects of cultivation techniques to generate new breakthroughs. High temperature and low mountains in western China, drought, lotus root production is very difficult, this technique can be lotus growing region to the western extension of the semi-arid areas, speed up the pace of development of the western plains region Lotus Lotus Lake is the main producing areas, this technology can improve Hutian low yield, but also can save water,[link widoczny dla zalogowanych], to overcome the problem of insufficient water. Water is a human survival and the basic conditions for national economic construction, while China's water situation is very grim, agricultural water use more difficult. Therefore, the lotus covered car temperature water planting techniques for the use of a bright future. 5.2 The lotus root should be noted that the technical aspects of aquatic plants are dicotyledonous 3, the plastic film mulching cultivation technology in specific production practices must pay attention to overcome the following problems: �� row of lotus too late. This technology is the key to highlight an To give full play to the warming effect of early; �� inappropriate species selection. Lotus varieties according to people's consumption habits and market demand to choose, the North used to eating raw lotus root, lotus root soup simmer South habits; �� number of less than normal sowing. Outian production potential, increase the seeding rate required, the general medium fertility plots, sowing rate per hectare to more than 6000kg; �� ditch the car standard is not high. To strictly regulate the ditch hand, adhere to the car for; �� Irrigation and Nitrogen poor. Lotus flood big fat production needs to re-applied manure,[link widoczny dla zalogowanych], nitrogen, phosphorus and potassium fertilizer to match; �� ineffective pest control called Lotus Root Rot disinfection, adhere rotation Huancha; �� clear plastic film does not pick up the net. Consider the pros and cons, if sufficient water can also be advanced in the latter part of removing film, which is convenient and conducive to removing film dressing; �� contiguous small. Focus area is small, not only affects water management, but also affect the market situation. 5.3 The academic significance for warming the car coated lotus water planting techniques successfully tested. Marked by the dry crop mulching technology extends to wet crops (rice), the further development of the aquatic crop, is the theory and technology of film covering a major breakthrough in the theory of the resulting technology system. Not only has a very important practical significance, and will have high academic value.
