在使用滴灌系统的农场,通常是在每一茬之后将毛管收走或在收获时毁掉。这样花费高,而且塑米废物的堆积也不利于作物生长。本文作者在美国建立了两个实验农场,探讨连作制下怎样连续使用土表下滴灌系统。研究结果表明:只要采取适当措 In farms that use drip systems, it is common to remove the capillary tube after each crop or destroy it at harvest. This is expensive, and the accumulation of plastic waste is not conducive to crop growth. The authors set up two experimental farms in the United States to explore how to continuously use subsurface drip irrigation systems under continuous cropping. The results show that: Just take appropriate measures
