摘要
1989~1991年对10年生国光和金冠苹果品种用多孔陶土管进行渗灌试验。结果表明:能节水和防涝,可增加土壤孔隙度和提高土壤养分含量,增加吸收根数量并促进树体的生长发育;座果率和单株(或单位面积)产量均比漫灌(对照)区高,果品质量有了明显的改善。
The results of permeated irrigation to 10-yr-old apple trees cv. 'Ralls' and 'Golden Delicious' from 1989 to 1991 were as follows:1.It can safe water and prevent waterlogging;2.It can increase' the soil porousity and availability of soil nutrients;3.It can make more absorbing roots and promote the growth of trees,with higher percentage of fertile fruit and yield per tree(or per unit area)than the flooding irrigation(C.K.);4.The fruit quality was improved obviously.
