Investigate the '43' solar greenhouse in Longfeng district. Describe the type , history, characteristics, and apply technologies of '43'soalr greenhouse.'43' solar greenhouse plays a important role in the development of protected horticulture in Longfeng district. The invest began in 2001.9,ended in 2003.9.by use of exploration,talking,and looking into on papers.research protected horticultural technology systemic.There are three types of '43' solar greenhouse in Longfeng District. The first is made of soil, The second is made of brick, produce technologies of the 2nd generation type of '43' solar greenhouse.The 3rd is made of brick and iron.this part tells us changes of '43'greenhouse products, technologies and the 3rd generation of '43' solar greenhouse, equipment of the greenhouse, and no pollution vegetable produce.Longfeng District began other researches in protect agriculture. The stress is cherry's greenhouse produce in winter. This part tells us the structure, technologies, and market operate plan.In the end, introduce three modern greenhouse and a kind of rummery in greenhouse.Develop no pollution vegetable products is the only way that we develop protect agricultre. We must solve following problem: one is soil hypo-salting .second is plant diseases and insect pests harmless control. Third is building vegetable industrial chain.Forth is product quality checLPut forward that improve other kinds of protect agriculture produce by '43' solar greenhouse's development, that occupy market by advantage of harmless vegetable, that improve the level of management and control of '43' solar greenhouse. Taking the cherry base as an education base will be good for its development.Postgraduate: Zhang YunxiuMajor: Olericulture Supervisor: Prof. Yu Xihong...
