Abstract
The semi-arid and arid regions located in the inland northwest of China, the drought index can reach 3.75-16.67, which seriously restricts the sustainable development of various local production activities. As a regional pillar industry, gravel-mulched watermelon has the characteristics of drought tolerance, high yield and high quality, etc. While expanding the area of gravel-mulched watermelon cultivation, side effects such as low production efficiency, irregular operation, little profit, destruction of the original biotope of farmland and ecological pollution have been highlighted. This paper took the problems highlighted in the process of watermelon cultivation in gravel-mulched fields as the starting point, reviewed the effects of agronomic measures such as breeding, mulching, disease and pest control, and supplemental irrigation of collected rainwater on the yield and quality of gravel-mulched watermelon . It clarified the shortcomings and improvements of the differences in research results due to strong locational variability , low representativeness of experimental years, and inconsistent results obtained by the same technical methods. The research on the gravel-mulched watermelon industry was further analyzed, so as to accomplish the aim of matching research with the application, and to achieve high yield and efficient cultivation of watermelon in gravel-mulched fields.关键词
