棉花地膜栽培技术的推广和应用,使棉花获得了大幅度增产,提高了植棉的经济效益,使农业生产达到了一个新的水平。但是,任何事物都是在矛盾中发展,由于年复一年的废膜回收不彻底,残膜在土壤中的残留量越来越多,给土地造成污染,其后果是非常严重的。 为了解决揭膜干净、全部回收的问题,农一师九团从1986年起将后期揭膜改为棉花灌头水前适时揭边膜的措施,从而克服了灌水时间与抗旱保产的矛盾,并且使地膜的热效应较充分地得到发挥。 人工揭边膜难度大,工效低,且容易造成伤苗和碰落棉蕾的情况。为了做好这项工作,九团在地膜机上进行了改装,研制了切割膜的小农具,通过两年的应用,证明效果很好。现介绍如下:
The popularization and application of cotton film cultivation technology have greatly increased cotton yield, raised the economic benefits of cotton planting and brought the agricultural production to a new level. However, everything is developing in contradiction. Since the waste film is not recycled year after year, the residual amount of residual film in the soil is more and more, causing pollution to the land. The consequences are very serious. In order to solve the problem of clean and complete recycling of uncovering film, the Ninth Ancestor Group of Nongyishi division changed the late uncovering film into the timely opening of cotton paddock before 1986, thus overcoming the contradiction between irrigation time and drought prevention and yield protection, And make the thermal effect of the film more fully to play. Uncovering the artificial film is difficult, inefficient, and easily lead to wounding buds and cotton buds touch the situation. In order to do this work, nine groups in the film mulching machine modified, developed a small film cutting tools, through the application of two years to prove effective. Now introduced as follows:
