一、甘蔗伸长期与气象条件的关系促进甘蔗伸长(或产量)的因素是复杂的,在这复杂的因子中,光温条件对甘蔗的影响是主要的。只有在较高气温和较多日照时数下,蔗茎才能长得又长又粗,有较高的产量和含糖量。一定的光照在不同的温度条件下,所形成的光合物质是不等量的,所以 First, the sugarcane elongation and weather conditions to promote sugar cane elongation (or yield) factors are complex, in this complex factor, light and temperature conditions on the impact of sugarcane is the main. Only at higher temperatures and more sunshine hours, cane can grow long and thick, with higher yield and sugar content. Certain light at different temperature conditions, the formation of photosynthetic substances are not equal, so
