江陵县弥市区是植棉历史较长的老棉区,也是重要的出口棉基地之一。常年植棉面积8万亩,1984年开始试验示范和推广地膜覆盖植棉新技术。当年示范推广3410亩,占总面积4.3%;1985年扩大到1万亩,占总面积12.5%;1986年呈下降趋势约为6000亩左右。为什么地膜棉发展缓慢,甚至出现下降趋势呢?我们认为其原因主要是地膜棉虽然可早发争早桃,但如果栽培管理跟不上却很易早衰,秋桃少,后劲不足,而我区秋桃在棉花产量中占举足轻重的地位,常年露地直播
Jiangling County, Miyagi district is a long history of cotton growing cotton area, is also one of the important export cotton base. Annual cotton area of 80000 acres, in 1984 began to experiment demonstration and promotion of plastic film covered cotton new technology. In the same year, 3410 mu of demonstration and extension was promoted, accounting for 4.3% of the total area. In 1985, the area was expanded to 10,000 mu, accounting for 12.5% of the total area. In 1986, the downward trend was about 6,000 mu. Why is the slow development of cotton membrane, or even a downward trend?
