Study On Utilization And Technological Extension Of Methane Residues O N Tomato In Greenhouse

The vegetable planted in big canopy of greenhouse is one of the important characteristics which rural industries improve. For solving the "Countryside, agriculture, peasant" problem, and changing "wicked under the light" in the course of current situation, Yang Ling pursue greenhouse vegetable and marsh gas project o in a more cost-effective manner.The project having already been possessed considerable scale so far, and have 3600 large canopies, 2000 marsh gas pools, and 137natural pond canopy complete sets, among which 96 sets have adopted c technology that author's popularize . And this kind of technology of the author's is still in continuing popularizing.How can make these two major organics to combine, and how to give play to heavy benefit and demonstration result on the whole high-order, it is the main question that the engineering department considers.This research is developed according to the theory of agricultural extension in recent years, According to prevent and cure the popularization of the tomato plant diseases and insect pests technology through the fat comprehensive utilization of natural pond, The author have used and developed the agricultural extension theory in practice, and explored the way to enlarge in agricultural extensionThrough this research, this thesis has drawn the following result:1. The natural pond apply is one of the ethnologies which is remarkable simply, benefit fertilizer, incompletely to operate that is worth popularizing withIn the large canopy tomato planting, it is one with little investment, high benefit, simply operating that the natural pond applies fertilizer incompletely. The natural pond can reduce chemical fertilizer and agriculture chemical consumption in the production process of tomatoes by a large margin, as to improve the output and quality and can control the tomato plant diseases and pests and take place effectively. The natural pond applies make the net income of every canopy can be add up 280-1000 Yuan.2. The natural pond can be utilized in various ways to be, and have remarkable results in improving the output of tomato and qualityNatural pond can be used in various ways in large canopy, as it can be used by base manure , can be used by top-dress , can be used by root and leave construct ,also can be soaked seed, Natural pond is very favorable in tomato seed sprouting, the seedling transplanting, corpora ting ,growing ,blossoming and bearing fruit. The natural pond as the organic fertilizer that detesting oxygen, to increasing the soil organic matter, has obvious results ,which can improve soil physics and chemistry properties , strengthen plant to be stalwart to grow, improve fruit rate, and can increase fruits heavily etc..3. The apply as fertilize of natural pond can incompletely control the plant diseases and insect pestsNatural pond be used incompletely among the tomato in large canopy, can great degree substitute agriculture chemical , can raise the ability to resist plant diseases and pests, to large canopy being that, and have better resistance to epidemic disease , gray mold , later viruses disease. Natural pond have a better prevention to sneak leaf fly andwhite powder louse that have resistance easily to insecticide .And the dialogue powder louse defends efficiency and is 45%, can realize that control diseases and insect pests ecology. This kind of function accords with the safety in production of the tomato.4. Natural pond applies as fertilizer is very much on offsetting the harmful environment extremely to function of shouldering the tomato growing.Natural pond can improve adaptability of environmental extremely; it can improve the tolerance to the extreme low temperature, extreme high temperature, the arid, and high wet environment of high temperature. Natural pond apply as fertilize makes low-temperature tolerance drop 1~2℃ in canopy, the high-temperature time of tolerance increases 2h,and have reduced the adverse effect on the tomato of the harmful environmental condition greatly.5. The different kinds of peasants' behavior can obviously influence the result of popularizingWhether through analyzing, find three different kinds of peasant behavior: hardworking type with knowledge, hardworking type, and lazy type. As the acceptation speed of technology and subjective response to be different in production in different kinds of peasant, the result of agricultural extension can be divided into good, comment lack by three kinds.6. It influences the factor of popularizing result which has five major respectsThrough studying about the incomplete popularization skill about utilizing of natural pond, from making analysis of technological demand, choice orientation, communication means, popularize tactics and popularizing management of technology in Yang Ling of peasant, this thesis think that peasant's demand and technological orientation have decided the peasant's attitude to popularizing , agricultural extension communication means, popularization tactics and popularizing managing, and influenced accepting the degree and the popularizing the result.7. It is main way that agricultural extension enlarges, to innovate popularize idea, reform popularize way, strengthen agricultural extensionBeen engaged in the experiences and lessons of agricultural extension at the basic level for many years according to the author, the way to enlarge the agricultural extension proposes three suggestions: First, establishing the new idea of popularization that "people first"; second, reform the way of agricultural extension; third, strengthen the mechanism of management of agricultural extension.
