甘蔗属热带植物,经过科研攻关、北移训化,在我国北方部分省份种植成功,取得了较大的经济效益。1998年我省甘蔗种植面积已超过5000亩。了解甘蔗的生物特性,掌握其北移的技术关键是种植户的必备知识。一、甘蔗的生长过程及特性甘蔗生长要经过五个时期,即:萌芽期、幼芽期、分蘖期、拔节期、成熟期。环境条件具备,气温在15℃以上,甘蔗才能萌芽。蔗芽出土6至8片叶叫幼芽期。8至12片叶叫分蘖期。7至9月份处于拔节期。10至11月上旬达到成熟期。二、甘蔗对环境条件的要求1、温度:当气温在15℃以上时,蔗茎内的酶开始活跃,将复杂的营养物质水解为葡萄糖和可溶性
Sugarcane tropical plants, after scientific research, the North shift training, planting in some provinces in northern China was successful, and achieved greater economic benefits. In 1998, the planting area of sugar cane in our province has exceeded 5000 mu. Understand the biological characteristics of sugar cane, to grasp the key technology of its north is the necessary knowledge of growers. First, the growth process and characteristics of sugarcane Sugar cane growth to go through five periods, namely: germination, young shoot stage, tillering stage, jointing stage, maturity. Environmental conditions are available, the temperature above 15 ℃, sugarcane germination. Sugarcane excavated from 6 to 8 leaves called shoots. 8 to 12 leaves are called tillering stage. From July to September at the jointing stage. 10 to early November to reach maturity. Second, the sugarcane environmental requirements 1, the temperature: when the temperature is above 15 ℃, the cane stem enzyme began to active, the complex nutrients are hydrolyzed to glucose and soluble
