As part of the research project, nine farmers were given materials and trained how to build and use a hoop house. 作为这一研究项目的一部分，九位农民获得了材料，并得到了如何建造和使用温室大棚的培训。

The results showed that well-managed hoop houses can grow high-quality crops. 结果显示，得到良好管理的温室大棚能生产出高质量的农作物。

However, crops are not the only things that grow well. 然而，不仅仅是农作物生长得好。

The researcher found that weeds grow faster in a hoop house. 研究人员发现在温室大棚杂草出长得更快些。

Weeding, seeding and watering requires at least as much work as crops grow in open air. 除草、播种、浇水至少需要与作物在露天生长一样的工作量。
