Selection Of Tomato Varieties In Greenhouse In Autumn And Winter And Effect Of Returning Corn Stalk To Field On Tomato Growth

In recent years,the cultivation area of vegetables in Solar Greenhouse in northern Shanxi Province has been expanding continuously,but there are some problems such as short time of sunlight,low temperature and insufficient accumulated temperature in the greenhouse,which make the fruits of thermophilic eggplant fruits difficult to expand and turn color,and seriously affect the quality production of overwintering tomato.In order to provide new technology for high quality production of tomato,the following results were obtained through variety comparison and deep burying under straw border1.From July 2018 to March 2019,in Yanggao solar greenhouse,8 tomato varieties(Fuchang 1466,Youshi 3,Ruifen 882,Provence,Tianxi 2,Tianxi 3,yuanfen 2,yuanfen 3)were used as materials.The results showed that yuanfen 2 had the largest yield(11137.82 kg/667 m2)by comparing the growth characteristics,yield and quality of tomato M2,followed by "Ruifen 882",10615.86 kg/667m2.The contents of soluble solids,lycopene and soluble protein of ’Ruifen 882’ were higher,which were 5.93%,49.95 μ g/g and 0.315 mg/g,respectively.The quality of ’Ruifen 882’ was good and its adaptability was strong,which could further expand the area test.2.From September 2018 to February 2019,"Fuchang 1466" and "yuanfen 2" were used as the test materials,and two treatments of burying straw under the border and without straw were used to compare the effects of different treatments on the growth,yield and quality of tomato.The results showed that deep burying straw under the border could promote the growth of tomato and increase the yield of tomato.After adding straw,Fuchang 1466 and yuanfen 2 were 12366.33 kg/667m2 and 12505.79 kg/667m2,respectively,which were 24.17% and 12.28% higher than the control.In addition,the soluble solids of the two varieties increased by 2.08% and 15.12% respectively.To sum up,through this experiment,it can be preliminarily determined that "yuanfen 2" and "Ruifen882" are suitable varieties for winter cultivation in northern Shanxi,supplemented by the technology of deep burying straw under the border,which can improve the quality and yield of tomato production in solar greenhouse.
