近年来,湖南、广东、广西等省(区)先后对甘蔗喷施稀土作了大量的试验、示范。研究表明:每亩甘蔗施40克硝酸稀土(成本费0.3元)可提高甘蔗糖分0.5％(绝对值),最高的达1.19％,每亩增加产量500斤左右。最高的达1.47斤。1984年湖南省还对“甘蔗喷施稀土的增产增糖作用”进行了省级鉴定,肯定了其增产增糖效果。它具有成本低、经济效益显著、使用方便,易被蔗农掌握等特点,1986年4月中旬在广西南宁市召开的全国甘蔗制糖学会上,把甘蔗喷施稀土作为提高原料产量和质量的重要措施之一。
In recent years, Hunan, Guangdong, Guangxi and other provinces (regions) have carried out a large number of experiments on the rare earths of sugar cane spraying and demonstrating. Studies have shown that applying 40 grams of rare earth nitrate per mu (cost 0.3 yuan) can increase the sugar content of cane by 0.5% (the absolute value), with the highest reaching 1.19% and the yield per acre about 500 pounds. The highest of 1.47 pounds. In 1984, Hunan provincial government also carried out provincial appraisal on the effect of sugar cane spraying rare earth on yield increase and sugar appreciation, affirming its effect of increasing production and increasing sugar. It has the characteristics of low cost, significant economic benefits, easy to use and easy to be mastered by sugarcane farmers. In mid-April 1986, at the National Sugar Sugarcane Society held in Nanning, Guangxi, sugar cane was sprayed with rare earth as an important ingredient to improve yield and quality of raw materials One of the measures.
