我国旱地甘蔗约占甘蔗总面积的75％,但亩产一般仅3吨左右。从1983年起,全国农业技术推广总站把“旱地甘蔗亩产5吨”作为重点农业技术推广项目,至1984年本项目已扩大推广到广东、广西、福建、四川和云南的11个县、市,亩产5吨蔗面积达到36.7万亩,占这些地区种蔗面积的20％以上,比推广前单产平均提高30％。因地制宜地应用这项技术,对于促进我国甘蔗生产水平的提高,将起着重要的作用。其技术要点如下: 一、深松整地,深沟浅种。丘陵旱地耕作层薄,保水、
China’s dry land sugar cane accounted for about 75% of the total area of sugarcane, but generally only about 3 tons per mu. Since 1983, the National Agricultural Technology Extension Station has put “5 tons of dry land sugarcane per mu” as a key agricultural technology promotion project. By 1984, the project has been extended to 11 counties and cities in Guangdong, Guangxi, Fujian, Sichuan and Yunnan , And the area of 5 tons of sugarcane per mu reached 367,000 mu, accounting for more than 20% of the total area of sugarcane in these areas, an average increase of 30% over the pre-sale yield. The application of this technology according to the local conditions will play an important role in promoting the improvement of the level of sugar cane production in our country. The technical points are as follows: First, deep loose soil preparation, deep shallow shallow species. Hilly dry land farming thin, water,
