从栽培技术上解决甘蔗高产防倒伏的问题,是目前和今后实现甘蔗高产稳产的一个重要关键,值得研究探讨。现就这个问题,谈一些浅见,供讨论。一、甘蔗高产倒伏原因分析近几年我区甘蔗种植面积近40万亩,单产不高,都在2.5吨左右,但也有部分面积亩产5吨、8吨、10吨,小面积(亩以上)超20吨的。比较高产的甘蔗,每年都有出现倒伏、折断蔗茎损失严重。造成甘蔗倒伏的原因主要有三个方面:(1)风害:甘蔗生长到中、后期,早的
It is an important key to solve the problem of high yield and lodging resistance of sugarcane from the cultivation technology, which is worth studying and researching now and in the future. Now on this issue, talk about some humble opinion for discussion. First, the analysis of causes of sugarcane high yield lodging In recent years, my area of sugarcane acreage of nearly 40 million mu, yield is not high, are about 2.5 tons, but there are also some area of 5 tons, 8 tons, 10 tons, small area (mu Super 20 tons. Relatively high yield of sugarcane, lodging every year, breaking the cane stems serious loss. The main reasons for the sugarcane lodging are three aspects: (1) wind damage: sugar cane growth to the late, early
