Studies on the High Yield and Low Cost Technology of Precocious Watermelon in Small Arch Shed under Double Film Mulch
Abstract： Based on field trials， heat preservation and moisture retention of precocious watermelon in small arch shed under double film mulch was studied under three kinds of typical weather. Results showed that the cultivation technology of watermelon in small arch shed under double film mulch had a better effect on heat preservation and moisture retentio
n， good for healthy growth of precocious watermelon. The yielding ability comparision of small arch shed with double film mulch， shed with triple film mulch and single film mulch cultivation technology was transversely done. Results showed the cultivation technology of precocious watermelon in small arch shed under double film mulch has less net profit than that of shed cultivation， but costs are less in management and investment. It is easy to be learned and accepted. Thus it should be popularized on large scale.红领巾心向党的内容
