自1979年起,我所遵循科研为生产服务的方针,坚持科研、示范、推广三结合的工作方法,在全省各个棉区建立了棉花地膜栽培研究成果示范样板田。四年来,示范面积由小到大,示范基点由少到多。到现在,全省有9个示范基点,示范面积共29348亩,占全省地膜覆盖面积的1/5左右。 Since 1979, according to the principle of scientific research for production service, we have adhered to the scientific research, demonstration and popularization of the three combined working methods and established a demonstration model field of cotton film mulching research achievements in all the cotton districts in the province. In the past four years, the demonstration area has grown from small to large and the demonstration base has grown from as little as possible. Up to now, the province has 9 demonstration base points, demonstrating a total area of ​​29348 mu, accounting for about 1/5 of the province’s mulching area.
