马铃薯膜下滴灌耗水规律的研究
Water Consumption Regulation of Potato under Drip Irrigation Mulched
摘要
Abstract
The changes of water consumption amount during the growth period and each growing period, water use efficiency were studied with KeXin No. 1 used as material. Results suggested that the top of water consumption amount and water consumption intensity in different growing periods of potato under drip irrigation mulched appeared in tuber bulking stage, and others were in tuber initiation stage, in seedling stage, and in starch accumulation stage with sequence. The water consumption amount and the average water consumption intensity during the growth period and each growing period of potato under drip irrigation mulched were all significantly higher than those without drip irrigation, except that in starch accumulation stage. The main soil water consumption layer of potato under drip irrigation mulched was at 0~ 40 cm in depth, and that without drip irrigation was at 0—60 cm in depth. The yield of potato under drip irrigation mulched was 55 596 kg/hm2 and was significantly higher than that without drip irrigation. The water use efficiency of potato under drip irrigation mulched was 11. 36 kg/mm, which was higher than that without drip irrigation, but the differences were not significant.关键词
