Present Situation,problems And Countermeasures Of Vegetable Production In Solar Greenhouse In Jingyang,Shaanxi

Jingyang County is located in the central part of Shaanxi province,with an average elevation of about 400 m.The annual average temperature is 13°C,the average annual precipitation is 548.7 mm,the annual sunshine hours are 2195.2 h,and the sunshine percentage is 48%~54%.It is a suitable area for the development of solar greenhouses.More than 30 years of development,it has formed a stable scale,achieved remarkable results,and faced certain problems.This paper investigates the production of greenhouse vegetables in Yunyang Town,Anwu Town,Zhongzhang Town,Sanqu Town and Qiaodi Town of Jingyang County,and reviews the advanced technologies of the development of greenhouse vegetables industry at home and abroad,and based on the problems found and propose countermeasures,promote the solar greenhouse vegetable industry in Jingyang County is expected to be efficient,healthy and sustainable.The main results are as follows:The development of vegetable industry in Jingyang County began in the late 1980 s and began to develop rapidly in 2009.In 2017,the county's vegetable planting area was 25,600 hm2,with an annual output of 1.8 million tons and an output value of 1.8 billion yuan,of which the facility vegetable area was 13,500 hm2,the greenhouse vegetable was over 6,000 hm2,and the facility vegetable industry was gradually scaled up.The county's per capita net income of farmers exceeds 45%.The technical limitation of the development of the solar greenhouse vegetable industry in Jingyang County: Individual greenhouse structure problems have affected insulation,the cultivation technology mastered by the vegetable growers is not high,low utilization rate of small work machines,low product rate,continuous cropping obstacle,high soil salinity and increased pests and diseases.Industrialization limitation of the development of the solar greenhouse vegetable industry in Jingyang County: diversified industries are still not perfect,product efficiency is not high,professional cooperatives are not strong,brand advantage is not obvious,hard to start financing,Land transfer.Several countermeasures for vegetable growers and local governments in solar Greenhouse in Jingyang County: optimize the greenhouse structure,implement standardized vegetable production,promote small machinery to carry operations,increase support for vegetable professional cooperatives and leading enterprises,strengthen brand building,strengthen cooperation with universities,increase technical training for growers,and vigorously promote new technologies for greenhouse vegetable production,policy support in areas such as agricultural insurance and land transfer.
