地膜复盖技术自1980年引进新疆以来,已经在瓜菜作物及棉花等经济作物栽培上,显示出极大的良越性。实践证明,它在新疆这样的干旱地区保苗、增产作用特别显著。因此,受到农业生产单位的普遍欢迎,短期内推广面积达数十万亩之多。当前,生产上迫切需要制定出一整套地膜复盖栽培的技术规范,以利最大限度地发挥地膜复盖栽培的潜力。本文就是我们采用正交试验设计法对地膜复盖下,瓜、菜作物的品种、施肥、密度三个因素进行的试验 Since the film mulching technology was introduced into Xinjiang in 1980, it has shown great superiority in cultivation of cash crops and cotton and other economic crops. Practice has proved that it is in Xinjiang in such arid areas seedlings, increase production is particularly significant. Therefore, it is generally welcomed by agricultural production units and the area for promotion in the short term is as much as several hundred thousand mu. At present, there is an urgent need to formulate a set of technical specifications for the cultivation of plastic film mulching in order to give full play to the potential of plastic film mulch cultivation. In this paper, we use the orthogonal design of the law on the film mulching, melon, vegetable crop varieties, fertilization, density of three tests
