原始语种摘要: Abstract(#br)The challenge to sustainable agriculture under increasing water scarcity has led to the notion of water-saving irrigation. In this study, we designed a special closed cultural system which can avoid water loss from soil surface and soil leakage. By using this system, we determined that at least 117.5 kg water was required for the whole life of one watermelon and the proportion of water requirement in the seedling, flowering, expanding, and mature stage was 10, 15, 65, and 10%, respectively. The potentially maximum irrigation water use efficiency (iWUE) for watermelon cultivation was 42.1 kg m −3 . For watermelon cultivation under plastic film mulching, the optimal irrigation amount was 1800 m 3 hm -2 and the proportion of irrigation amount in the seedling, flowering,...
