摘要
甘蔗农艺和经济性状的统计分析表明:喷施稀土对甘蔗的增产作用,主要是提高成茎率从而增加甘蔗的有效茎数;喷施稀士对甘蔗的增糖作用,主要是促熟而提高了成熟早期的蔗糖分;喷施稀土对甘蔗的促熟作用,主要在于加速成熟早期蔗糖分的积累速度。
Statistical analyses for agronomic and economic perfermances in sugarcane showed that the role played by spraying RE in increasing cane yield was mainly due to an increase in the number of millable cane resulted from raising the formative rate of stalk.The effect of spraying RE on increasing sucrose content in sugarcane was just because of raising sucrose content in the early ripening stage associated with the advacement in mutaring.The response of advancing maturing of sugarcane by spraying RE was chiefly owing to acce- lerate the rate of sucrose accumulation in the early ripening stage.
