广东地处热带、亚热带,适宜甘蔗生长。但是冬、春(12月～翌年3月)季节雨量偏少,月降雨量仅19.6～91.5毫米,气温常低于15℃(月平均温度13.4～17.7℃),而宿根、冬植及早春植蔗萌芽期正值此时期,因而发株少。成苗率低,蔗苗素质差,断垄缺株多,生长缓慢,严重影响单产,是历年来这三个植期甘蔗面积少的主要原因。众所周知,提早种植,延长生长期是甘蔗获
Guangdong is located in the tropical and subtropical, suitable for the growth of sugarcane. However, in winter and spring (December to March next year), the rainfall in the season is less than normal, and the monthly rainfall is only 19.6-91.5 mm. The temperature is usually below 15 ℃ (monthly average temperature 13.4-17.7 ℃) Cane germination period is at this period, which made less hair. Seedling rate is low, poor quality of sugarcane seedlings, broken ridge lack of more strains, slow growth, seriously affecting the yield, over the years is the main reason for these three planting sugarcane area. As we all know, planting early, to extend the growth period is sugarcane harvest
