一、前言近年来随着科学技术的进一步发展,稀土已广泛用于各种农作物,应用于甘蔗已初步取得可喜的成绩,增产和增糖都有一定的作用。目前生产上主要是使用低浓度的稀土溶液在分蘖期前喷施叶面,在一些地区一些田块效果不够明显,可能是土壤中已含稀土所致。本文主要采取低浓度的稀土溶液浸甘蔗种茎的方法,来研究稀土对甘蔗苗期的增产效应。

I. Introduction In recent years, with the further development of science and technology, rare earths have been widely used in various crops. The application of sugarcane has made gratifying achievements initially, and the stimulation and stimulation of sugar production have a certain effect. The current production is mainly the use of low concentration of rare earth solution before spraying tillering foliage, some fields in some areas effect is not obvious enough, may be due to the soil has been caused by rare earth. In this paper, low concentrations of rare earth solution of sugar cane stems to study the effect of rare earth on sugar cane seedling yield.
