| 摘 要： | 为研究新疆不同土壤含水率下限对工业番茄生长、耗水量产量及水分生产率的影响,以工业番茄为研究对象,进行测坑试验,开展了膜下滴灌模式下的工业番茄试验.试验表明:工业番茄的灌水次数和总灌水量随着土壤含水率下限的增大而变大.在计划湿润层设置为固定的40 cm深时,灌水定额随土壤含水率下限的降低而增加.工业番茄的株高、叶面积指数...

| Abstract: | In order to study the effects of different lower limits of soil water content on the growth,water consumption,yield and water productivity of industrial tomatoes in Xinjiang province,a pit test is carried out with industrial tomatoes as the research object.The results show that the irrigation times and total irrigation number of industrial tomatoes increase with the increase in the lower limit of soil water content.When the planned wet layer is set to a fixed depth of 40 cm,the irrigation quota increases with the decrease in the lower limit of soil moisture content.Plant height,leaf area index and chlorophyll content of industrial tomatoes increase first and then decrease during the growth period.The lower limit of soil moisture content suitable for industrial tomatoes physiological indexes is 65%,corresponding water consumption was 405.0 mm,irrigation times are 7,and irrigation quota is 57.8 mm. |
