喷灌作为先进的灌溉技术之一,近年来在我国迅速发展,各地相继涌现出一批性能良好的喷灌机具,在农业生产中起了很大作用。但是,由于喷灌机具品种繁多,规格不一,大同小异,互不通用,给大批量制造、专业化生产造成很大障碍,尤其是不利于使用维修。这种状况将束缚喷灌技术的高速度发展。因此,在前一阶段群众运动的基础
As one of the advanced irrigation technologies, sprinkler irrigation has been developing rapidly in our country in recent years. A series of sprinkling irrigation equipment with good performance has emerged in various places and plays an important role in agricultural production. However, due to a wide range of sprinkler irrigation equipment, different specifications, similarities and incompatibilities, to large-volume manufacturing, specialized production caused great obstacles, especially not conducive to the use of maintenance. This situation will tie the rapid development of irrigation technology. Therefore, the basis of the mass movement in the previous period
