Abstract

Maize refers to one of the major food crops worldwide. Its yield has a direct effect on the global food security. Moreover, cultivated lands in the world have been undergoing serious degradation. In the present study, the field experiments were performed in the middle of Jilin, China. Besides, a novel maize cultivating method, combining drip irrigation under film mulch cultivation and high photosynthetic efficient cultivation, was presented. NUE, WUE, accumulation temperature, plants growth and yield were determined in high photosynthetic efficient cultivation with the drip irrigation under mulch and that under the mulch with transparent and black film, respectively. As revealed from the results, the high photosynthetic efficient cultivation based on drip irrigation cultivation could increase the yield of rain-fed treatment by 53%; high photosynthetic efficient cultivation with drip irrigation under film mulch cultivation could also improve NUE and WUE compared with conventional drip irrigation under film mulch cultivation; transparent mulch could more significantly rise the soil temperature than black mulching, as well as improving the maize yield. The present study presented a novel planting mode in accordance with reliable theory to sustainably develop maize.
