不同灌排模式对避雨环境下番茄品质的影响
Influence and Optimization of Different Irrigation and Drainage Modes on Fruit Quality of Tomato Cultivated in Rain-shelter
摘要
Abstract
In order to optimize good-quality and water-saving tomato cultivation mode in Southern China , the author studied the influence of different irrigation and drainage modes on the fruit quality of tomato under rain-shelter condition.The results showed that tomato quality in the check T1(without rain-shelter measure) was poorer than that in other treatments.Under the con-dition of the same concealed drainage conduit depth , the element content in tomato fruits in the treatment of full irrigation was sig-nificantly lower than that in the deficit irrigation treatments , and the soluble sugar content in the least irrigation treatments T 6 and T10 was 35.18%and 38.93%higher than that in the check, respectively.Under the condition of the same irrigation lower limit, the element content generally increased with the increase in concealed drainage conduit depth , but concealed drainage conduit depth had no significant impact on the soluble solid content .The tomato quality in different irrigation and drainage treatments was evaluated by using principal component analysis (PCA), and the results indicated that the treatments T4 and T8 obtained the highest score of comprehensive principal component , and they were the optimum modes for the good-quality and water-saving cultivation of tomato.关键词
