近年来国内许多单位的试验结果证明,地膜覆盖栽培是瓜菜作物增产的有效措施。但对地膜覆盖栽培技术规范的研究较少。本文通过地膜、肥料及密度三因素对西瓜作物产量和品质影响的研究为确定较优栽培技术方案、取得更高的经济效益提供了依据。 一、材料与方法 本试验1983年在天山 In recent years, many domestic units of the test results show that plastic film mulching cultivation is an effective measure to increase yield of melons and vegetables. However, there are few researches on the technical specifications of mulching cultivation. In this paper, through the three factors of plastic film, fertilizer and density on the yield and quality of watermelon research to determine the optimal cultivation techniques and programs, to provide a higher economic benefits. First, materials and methods The test in Tianshan in 1983
