【摘要】 为研究连栋日光温室番茄岩棉高产高效栽培技术,对连栋温室内的生产因素进行了跟踪调查,并分析了苗龄、温度、光照、昼夜温差、灌水量等生产影响因子对番茄产量的影响。通过分析得出:连栋玻璃温室番茄越冬生产,日历苗龄为90 d时,番茄单株坐果数多,单穗平均坐果数多;昼夜温差为5.3℃时,番茄生长最快,单月产量也为最高;每天最小灌水量为1.4 L/m~2,净灌水量为0.3~1.0 L/m~2,即最大回液量应小于78%,最小回液量应大于28.6%,每月给水量为250 L/m~2为宜;当光照总和为1 800 J/cm~2,每月给水量应大于320 L/m~2。更多还原

【Abstract】 In order to research the techniques of tomato cultivation with rock wooi in span greenhouse,the test of the production factors just as seedling age,temperature,light,day and night temperature,amount of water and other production factor on tomato yield impact were analyzed.Through the analyzing results we can see that:when we culture tomato with rock wool in Winter in span glasshouse.90 days seedling age can produced more fruit in every cluster;when the temperature difference is 5.3℃ between day and night,the tomato growing faster and much more tomato can be harvested;the minimum quantity of given water is 1.4 liter per square meter per day,the net quantity of given water is 0.3-1.0 liter per square meter,the maximum drain should be less than 78%,the minimum drain should be more than 28.6%,and the appropriate average given water is 250 liter per square meter per month.When the light sum is 1800 J/cm~2,more than 320 liter water should be given per square meter per month.更多还原
