Low-lying saline-alkali soil of spring wheat cultivation techniques


Path. (4) timely early sowing, crop growth period of adjustment to achieve the purpose of salt [. (5) to clear the channel, change the result of poor drainage caused by increased soil salinity [. (Continued on page 56) 562 009 No. 2 Agriculture and Forestry Science and Technology 4 discussion from the above analysis, it can initially determine the Ningxia Irrigation District livestock manure and other pollutants to water, land and other environmental caused some impact, but with a high degree of aquaculture industry development of eastern coastal areas and Beijing, Shanghai and other big cities compared to the threats to the environment is relatively small. Over the years,[link widoczny dla zalogowanych], Ningxia Irrigation District livestock farming industry has been taking the combination of the road. Time to build market earlier in the farm business, while livestock and poultry breeding fruit trees, forest, pasture, crop cultivation and other pond fish. Also some large farms and planting the formation of a stable relationship, livestock manure produced by filling a simple treatment such as washers, or compost made from manure,[link widoczny dla zalogowanych], as fertilizer returned to farmland. Multi-farm manure removal by manual or mechanical process conservancy-based, water conservancy, supplemented by discharge of sewage. Some have established a large farm manure digesters and the safe disposal and comprehensive utilization of waste water, as well as farm manure produced by microbial fermentation of organic fertilizer. In addition, Ningxia irrigation area and livestock manure emissions of pollutants and so on is estimated by the content, may have a certain gap between the actual situation of the Yinchuan City suburb, Litong District, Zhongwei City suburb cows, pigs, poultry scale farming industry is relatively developed, its environmental impact than the estimated value by the high. Ningxia Irrigation Area is located in the upper reaches of the Yellow River,[link widoczny dla zalogowanych], Yellow River water have benefits, planting forage yield,[link widoczny dla zalogowanych], good quality, suitable for building large-scale, intensive farms and processing base. Ningxia Irrigation Area is the main area of dairy farming to dairy-based farming has developed rapidly. Some studies showed that: a serious water pollution in China, the watershed, livestock breeding and living sewage water basin is caused by nitrogen and phosphorus eutrophication the main reason, its contribution to industrial pollution, much more than ridicule. Development process in the aquaculture industry, due to neglect of environmental impact, of some of the major river basin has been a certain degree of pollution, 2_4 ~. Therefore, the development of the aquaculture industry in Ningxia irrigation area at the same time,[link widoczny dla zalogowanych], environmental pollution control should be prepared for manure produced by aquaculture, waste water, odor using sound processing, resource utilization and control measures to prevent pollution of the Yellow River water.
