Dear Grandpa,

How are you these days? I have been missing you very much after I went to college a year ago. Whenever I think of the old days, I feel very happily. I still remember when I was a child, you always held me in your arms and told me stories till I fall asleep. We often went to the fields to enjoy the pleasant view there. You told me the name of different plants and characteristics. Gradually, I became interesting in biology and chose to learn biology when I entered into the college. Now my friend Ann, together with me, are going to do field study and the findings will be use as materials for our research. Since we’ll do the study in our hometown,so I hope to see you then.

Farmers and gardeners have long used greenhouses to extend the growing season in cold weather. Now, hoop houses are gaining popularity. Some hoop houses are rounded; others are shaped more like a traditional house.

A hoop house is basically a metal frame covered with plastic or other all-weather material. A common design looks like a high tunnel. Unlike a greenhouse, which uses a heating system, a hoop house is heated by the warmth of the sun.

Now, the United States Department of Agriculture has announced a program to help farmers who want to build hoop houses. The department has been supporting a project in Michigan. That state has a short growing season. As part of the research project, nine farmers were given materials and trained how to build and use a hoop house. The results showed that well-managed hoop houses can grow high-quality crops.

However, crops are not the only things that grow well. The research found that weeds grow faster in a hoop house. Weeding (除草), seeding and watering requires at least as much work as crops grown in the open air. The researchers also advise growers to add compost（堆肥） material to the soil in hoop houses to build nutrients.

Eliot Coleman is an organic farmer and a writer in Maine who has helped popularize the idea of four-season farming. His ideas about hoop houses sounded good to John Biernbaum in the Horticulture（园艺）Department at Michigan State University.

Professor Biernbaum tried hoop houses on the Student Organic Farm at Michigan State and had success. Project director David Conner says it was a "test drive（试车）" for the research on private farms. The agricultural economist points to the demand for locally grown crops. "People are hungry for good, fresh vegetables," he says.
