荔枝是我国南方传统的特产水果。元江县栽培荔枝不但历史悠久,还试验出一套荔枝高空压条育苗新技术,现简介如下: 一,高空压条成苗的原理高空压条法又叫环状剥皮法,其成苗的科学道理是:当枝条某段经过环状剥皮后,由于输导组织的切断,环上方叶片光合作用所制造的营养物质就不能继续往下输送。其结果是,这些营养物质便积累在伤口部位,从而加速了这个部位愈合组织的形成,同时也就刺激了这
Lychee is the traditional specialty of South China fruit. Yuanjiang cultivation of litchi not only has a long history, but also to test a set of litchi high-altitude seedling nursery new technology, are as follows: First, the principle of high-pressure bar into seedlings High-pressure bar method is also called annular stripping law, the scientific truth of its seedlings are: When a section of the branches after ring-shaped peeling, due to the cutting of the conduction tissue, the photosynthesis of the leaves above the ring can not continue to carry nutrients down. As a result, these nutrients accumulate at the wound site, which accelerates the formation of healing tissue at this site and stimulates this
