加气滴灌对棉花苗期土壤酶活性及棉花生理生长的影响
Effects of gas drip irrigation on soil enzyme activity and physiological growth in the seedling stage of cotton
摘要
Abstract
To study the effects of different aerated irrigation conditions and soil depths on soil enzyme activity and the physiological growth of cotton seedlings,the experiments were set up with 4 irrigation rates(0,25%,50%,75%)and 3 soil depths(0,5 and 30 cm),totaling 10 treatments with 3 repetitions.As a result,we observed the following:1.At the same irrigation rate,a soil depth of 5cm led to the best performance,with aerated irrigation significantly improving the growth indicators of cotton seedlings(plant height,stem diameter,root length,underground dry matter,and above-ground dry matter).When aeration was at 50%level compared to no aeration,the growth indicators increased by 32.67%,36.81%,39.88%,47.80%,and 111.38%,respectively.Furthermore,aerated irrigation significantly increased the SPAD value of cotton seedlings.2.With the increase of aeration rate,a significant short-term enhancement of the antioxidant enzyme activities in cotton was observed,along with the reduction in malondialdehyde content.At a soil depth of 5 cm with an aeration rate of 75%,compared to no depth and no aeration,the activities of the superoxide dismutase(SOD)and peroxidase(POD)in cotton seedlings'leaves increased by 50%and 157.58%,respectively.3.Aerated irrigation and different soil depths significantly affected the activities of soil enzymes(catalase,urease,alkaline phosphatase,and soil sucrose enzyme)in cotton seedlings.At a soil depth of 5 cm,the 50%aeration treatment increased their activities by 45.25%,32.14%,65.82%,and 53.01%respectively,compared to no aeration.In addition,the combination of 5cm underground drip irrigation belt burial depth and 50%air filling rate turned out to be the most suitable for the growth of cotton seedlings.Overall,the aeration treatment could lead to much stronger physiological growth performance of cotton.In other words,the combination of aerated drip irrigation with different soil depths demonstrated good application potential,which would be likely promoted in future agricultural management and irrigation optimization.关键词
