Study On Installation Farming System

Based on the related researches of predecessors, combining installation farming with farming system, exploring the interaction effect between land and universe factors and resource potential productivity under installation condition, lucubrating on the mechanism and patterns of using resource efficiently in different cropping system under installation condition, and putting forward the theory of establishing installation farming system and its technology system are for the purpose of improving the sustainable development of installation farming, relaxing the contravention between population increase and resourcesshdrtages and realizing the sustainable improvement of resources productivity.The paper includes 9 chapters. Chapter one is the foreword, in which, based onanalyzing entirely the problems in faced of farming system in present developing stage and the effects and position of installation farming in the sustainable development of agriculture of China, it was considered that installation farming started a new field for the development of farming system and installation farming system will be a new direction of the development of farming system, and the basic thinking of the research is put forward.Chapter two summarizes internal and external situation of installation farming and the history of Chinese farming system and its researching headway, and analyses the shortcoming existed in innovation and research of Chinese farming system, and brings forward definitely that the trends of the development of Chinese farming system for the future are installation farming system and ecological farming system.Chapter three gives definition of installation farming system and some concepts related, and defines the characteristics of installation farming system distinguishing from that of traditional farming system.Chapter four, based on expatiating on the characteristics of installation farming and its production essential and the composition, types and characteristics of installation farming ecological system, brings forward the basic principles of establishing installation farming system include living factors of plant and its regulation theory, poly-dimensional land use theory, biology theory, solar energy utilization theory and agricultural technological-economic theory.Chapter five, based on detail analyzing the characteristics and types of weather throughout the country, expounds the distributing and application of main types of installation farming production, such as plastic ground covering, plastic tunnel, commonplastic greenhouse, energy -saving solar greenhouse and modernization greenhouse.Chapter six, by studying on the changing laws of environmental factors, such as light, temperature, humidity, air and soil, under installation condition such as plastic ground covering, plastic tunnel, plastic greenhouse, and analyzing the effects of those ecologic factors on cropping system, proposes the measures and technologies of regulating installation condition synthetically.Chapter seven expatiates the arrangement of plants, crop rotation and continuous cropping, crop harvesting system, the arrangement of crop stubbles and crop planting modes under installation condition. Crop planting modes are classified into four types, according to crop group, space occupied and the times of crop plant-harvesting in a year, such as one crop one year, single crops in different season of a year, more than two crops inthe same season of a year, more than two crops in different season of a year, underinstallation condition. The main crop planting modes used in film covering, plastic tunnel and plastic solar greenhouse are introduced briefly.Chapter eight brings forward comprehensive regulating techniques of light, temperature, humidity, air and soil under installation condition.Chapter nine makes general summery of the main conclusions, and makes discussions on related questions.The main achievements of the research are as follows:(l)The paper proposes installation farming system and...
