Precision agriculture technology is being rapidly developed and adopted worldwide because it allows agricultural production inputs to be based on plant needs at different sites within a field.Precision agriculture technology is traditional agriculture to the path of agricultural modernization in our country.The many advantages of water saving and fertilizer saving,increase yield,improve quality,improve the agricultural environment,etc.In recent years,with the rapid development of economy and technology,people more and more attention to the development of precision agriculture technology.The government began to the attention and support for precision agriculture technology.The precision agriculture technology,which should be convenient,efficient,practical,and widely applicable,could provide a new theoretical basis and technical support.Therefore,modern greenhouse agriculture integration of water and fertilizer in intelligent management technology will become the inevitable trend in the development of precision agriculture technology.In this study,tomato substrate cultivation technology and integration of water and fertilizer in the intelligent management system are studied.The following results were obtained in this study:1.Effect on yield and quality of tomato under different irrigation lower limit and nutrient solution concentrations.The effect of different irrigation lower limit and nutrient solution concentrations on the yield?quality and water use efficiency of tomatoes.The appropriate irrigation lower limit and nutrient solution concentration of soil less cultivation of local tomato was determined.Results of the study can be used to provide the basis for the yield and efficient cultivation of local tomatoes.The “Zhong-yan 100” tomatoes were used as the experiment material.Three nutrient solution concentrations and three irrigation limit were selected as nine treatments in two-factor test.The results showed that contents such as soluble sugar,vitamin C,lycopene and nitrates,et al reduced with the increasing of the irrigation limit and increased with the increasing of the nutrient solution concentration and then reduced.The yield of tomatoes showed a rapid-slowly increasing trend with the increasing of the nutrient solution concentration and irrigation limit.The water use efficiency increased with nutrient solution concentration and reduced with the increased irrigation limit.There for,the nutrient solution was not the more concentration,the better and so as the irrigation limit.Only one reasonable nutrient solution concentration and irrigation limit was conducive to the yield and quality of tomatoes.When the nutrient solution concentration was 1.18 times and irrigation limit of 75.06% of field capacity,the tomato yield per plant had the highest value of 2.32 kg.2.Intelligent management system for greenhouse tomato based on integration of water and fertilizer.We have introduced the research status quo of integrated water and fertilizer management system through analyzing the application situation and development of fertigation utilization at home and abroad.On the basis of this analysis,the research of integration at integrative water and fertilizer and intelligentized management system are described.The important of agricultural modernization are analyzed in water and fertilizer integrated intelligent management system based on integrative water and fertilizer and put forward the overall architecture of the system.We Introduced the composition of intelligent management system based on integrative water and fertilizer,designed the automatic control and manual control of combining the dual control mod in view of the actual production requirement.Finally we researched and completed integrative water and fertilizer and intelligentized management system which achieving the automatic irrigation control nutrient solution.We finished the Tomato cultivation matrix field test and test combining integrative water and fertilizer and intelligentized management system.Test results showed that collector performs stable,Man-machine interface set is concise and clear,operation is simple and convenient,to meet satisfy different users,software and hardware design is reasonable,meet the requirements of precise and intelligent on integrative water and fertilizer.
