摘要
以"中农20号"黄瓜为试验品种,研究加气地下滴灌对温室秋黄瓜生长状况、产量和干物质构成的影响.滴灌带埋深共设3个水平,分别为10 cm、20 cm、30 cm,加气处理分为2个水平(每天加气1次、不加气),共6个处理,各处理灌水定额均为187.5 m3/hm2.结果表明:在不同的滴灌带埋深条件下,加气处理均可以促进黄瓜的茎粗、株高、叶面积以及根部的生长.加气灌溉在滴灌带埋深20 cm(T2)时,最适合黄瓜茎粗、株高、叶面积的生长和提高茎叶的干物质累积量.在相同的周期内,T2处理的茎粗较不加气处理(CK1、CK2、CK3)的茎粗增加了8.68%~18.84%,株高增加了7.05%~18.37%,叶面积指数增加了5.69%~21.01%.与对照组的黄瓜产量比较,加气灌溉在滴灌带埋深为20 cm(T2)时对黄瓜的增产作用最大,较CK1、CK2、CK3分别提高了41.57%、13.03%、8.87%,同时对根系生长的促进作用最大,提高了根干物质的累积量.
＂Zhong Nong 20＂ was taken as the test variety in this experiment.The effect of aerated on the growth,yield and dry matter composition of autumn cucumber was studied.Three levels of drip irrigation belt buried deep were 10 cm,20 cm and 30 cm respectively and aeration treatment was divided into 2 levels（1 time/d,no aerate） with6 treatments,and the irrigation quota was 187.5 m3/hm2.The test results showed that the growth of stem diameter, plant height,leaf area and root of cucumber can be improved by aerated drip irrigation under the conditions of deep buried depth of different drip irrigation tapes.Aerated irrigation was suitable for the growth of cucumber stem diameter,plant height,leaf area and the dry matter accumulation of stem and leaf when the depth of drip irrigation was 20 cm（T2）.In the same period,the stem crude of T2 increased by 8.68% ~18.84%, and the plant height increased by 7.05% ~18.37%,and the leaf area index increased by 5.69% ~21.01% compared with that of no aeration treatments（CK1,CK2,CK3）.Compared with the cucumber yield in the control groups（CK1,CK2,CK3）,the aerated irrigation had the greatest effect on the yield of cucumber when the depth of drip irrigation was 20 cm（T2）,which increased 41.57%,13.03% and 8.87% respectively.At the same time,it had the greatest effect on the growth of root system and increased the accumulation of root dry matter.
