甘蔗烂种烂芽是新植蔗中比较突出的问题。现将甘蔗烂种烂芽的主要原因及防止措施介绍如下:一、主要原因:①蔗种。有些地方的蔗农仍习惯用全茎作种,由于基部几节的芽老化,蔗糖多于还原糖,而可溶性氮化物较少。播种后,种苗因得不到足够的还原糖而不发芽或死芽。另外,藏种的时间过久,种苗失水过多,也是造成死芽的一个原因。如未经过严格选种和浸种,烂种烂芽就会更加严重;②水分。水分对甘蔗的影响最大。在萌芽期甘蔗对水分的需求量不大,然而一般地区春季的雨水都较多。如果在春季多雨期不注意清沟排水, Rotten bud rotten varieties of sugar cane new sugarcane in the more prominent issue. The main reasons for rotting buds and precautions are described below: First, the main reason: ① cane varieties. In some places, sugarcane farmers are still accustomed to using the whole stem for seed germination, sucrose is more than reducing sugars due to the buds in the basal section, but soluble nitrogen compounds are less. After sowing, seedlings can not get enough reducing sugars without germination or dead buds. In addition, Tibet’s time is too long, too much water loss seedlings is also a cause of dead buds. Without strict selection and seed soaking, rotten buds will be more serious; ② moisture. Water has the greatest impact on sugar cane. In the budding period, the demand for moisture in sugarcane is not large, however, in general, there is more rain in spring. If you do not pay attention to rainy season drainage ditch drainage,
