一、北方旱区双覆膜栽培甘蔗 甘蔗起源于热带、亚热带雨林地区,其生态环境决定了甘蔗喜光好气、高温高湿的自然气候。建国40多年来,我国的种蔗区域一直限于长江以南地区,故有“蔗不过江”之说。随着近几年南凉北热的气候逆差,南蕉北移、南桔北种相继成功,但如在北方旱区栽种甘蔗,在温度、湿度、光照、空气土壤含水量和降雨量方面存在着诸多制约因素的条件下。
First, the cultivation of double-film cultivation in the northern arid region Sugarcane sugarcane originated in the tropical and sub-tropical rain forest regions, and its ecological environment determines the natural climate of sugarcane hi light and airy, high temperature and high humidity. For more than 40 years since the founding of the People’s Republic of China, the species of sugarcane in our country has been limited to areas south of the Yangtze River. In recent years, with the cold climate of the south and cool north, the south banana has been moved northward and the northern ones have been succeeded one after another. However, if sugarcane is planted in the northern arid region, there exist in temperature, humidity, light, air and soil moisture content and rainfall With many constraints under the conditions.
