| 摘 要： | 以日光温室黄瓜为试验材料,采用膜下滴灌,研究不同灌水下限处理对黄瓜的形态、根系、光合、保护性酶、产量、品质等造成的影响,并比较、筛选适宜灌水下限。研究结果表明在试验处理的灌水下限范围之内,随着灌水下限的增加,植株的株高差异不明显;根长密度、果实水溶性总糖含量随之减小;植株的叶面积、节点数、气孔导度、光合速率、产量、果实内的氨基酸、还原型Vc、水分含量随之均有不同程度的增加。灌水下限为85%FC的处理,其产量最高、品质最优,可以将其作为黄瓜温室膜下滴灌栽培的适宜灌水下限。

| Abstract: | Cucumber with different irrigation lower limits under the drip irrigation covered with the plastic film was studied.By analyzing indexes of cucumber morphology,root,photosynthesis,protective enzyme,output and quality,one ideal irrigation lower limit could be found out by contrast.The results as followed: in the conditions of the experimentation,the differences of altitude between different treatments are not remarkable.Leaf area,node number,stomatal conductance,photosynthesis,output,content of amino acid an... |
