Investigation And Analysis Of Three Greenhouse Environment Factors Tomato Cultivation Techniques

With the facilities development situation on WuYi Farm in western suburbs of Urumqi and three different greenhouse structure as the research object,makes a survey of development scale of greenhouse cultivation,constitution,planting area,quantity of production and planting crops;meanwhile,three environmental factors change in greenhouse which constructed by color plate,brick masonry and concrete wall;with the delayed tomato cultivation techniques after autumn,the growth,quality,production and efficiency are investigated,conclusions are as follows:(1)From 2010 to 2016 on WuYi Farm,the greenhouse scale and output have grown with the color plate greenhouse scale and output.Starting in 2014,the color plate greenhouse which hold dominant position in greenhouse production accounts for 56% of greenhouse.(2)The edible-fruit-vegetable greenhouse is more than two-thirds of the total planting area and output.The output value of vegetable unit area in greenhouse is much higher than that of the outdoor vegetable unit area,high 63900 yuan per mu in 2014,60000 yuan per mu in2015,and 58200 yuan per mu in 2016.It is possible to determine the relative decline in the yield per acre of greenhouse vegetable crops due to the factors such as the scale of crop cultivation and the cost of management.(3)The color plate greenhouse among three types of greenhouse is the best in terms of temperature,light intensity and wet effect.In terms of plant traits and quality of products,the relationship of color plate greenhouse > brick masonry greenhouse > cob wall greenhouse.Therefore,the performance of color plate greenhouse is superior to the cob wall greenhouse and brick masonry greenhouse.(4)After recovering the cost,the estimated net profit that the cob wall greenhouse is147600 yuan,brick masonry greenhouse is 175500 yuan,and the color plate greenhouse is285600 yuan.To the conclusion,the net profit of color plate greenhouse after recovering the cost is expected to be much higher than brick masonry and cob wall greenhouse.If government takes the lead in the long term,it is recommended to adopt the color steel greenhouse.
