The Investigate Of Drip-fertigation And Popularization To Corn In Guangdong

Integration technique is the body of water and fertilizer to overcome water shortage, drought conditions in farming agriculture to achieve sustainable development and effective way. In this thesis, Huizhou, Guangdong Province Ruhu Housing Village dryland corn production increase to achieve comparative field trials, based on the integration of water and fertilizer from corn technology test results and the success of many years of experimental studies have shown that one application of fertilizer technology enables corn in drought conditions fertilizer cost savings of13%, saving up to70%, labor cost savings of30%to water, fertilizer, labor, yield good results, the promotion of agricultural water use from extensive to intensive change, promote agricultural production and incomes, and promote modern agriculture and building a new socialist countryside has important practical significance.In this paper, in the " fertilizer integration" technology to promote the process of the problems found in the current province of existing agricultural extension system is still a product of the planned economy, the administrative extension system has obvious characteristics of this national promotion agencies based, neglect farmers also benefit system has become increasingly unsuited to promote rural economic development in our province and the market process requirements. Mainly reflected in the integration of water and fertilizer on farm level understanding is not deep, low level of technology, learning narrow channels, as well as insufficient funding mechanisms such as the level of the government in terms of policy, funding, and lack of talent into the system, insufficient promotion team training other issues, the perfect integration of water and fertilizer technology promotion measures and suggestions, intention to explore further improve the existing agricultural extension system, promote corn " fertilizer integration" technology promotion, the formation of dry crops for planting corn in Guangdong economic and efficient Festival water, fertilizer fertigation technology systems and management procedures, as approved by the Guangdong farmers and bring greater efficiency. The integrated water and fertilizer technology in the promotion of the development of agriculture in our province, will have broad application prospects and social significance.
