稀土微肥在农业生产中已被广泛应用,关于它对各种作物增产效果的研究,国内外报道的资料很多。我校于1987～1988年进行了稀土微肥对玉米肥效的研究工作。经过两年的田间试验初步认为,用稀土微肥拌种和喷洒玉米,可以促进植株个体生长,调节各器官的发育,缓和植株营养生长和生殖生长的矛盾,增加穗粒数、千粒重和产量。施用稀土微肥还具有用量少,成本低,施用技术简单的特点。一、试验材料与方法
Rare earth fertilizer in agricultural production has been widely used, on its effect on the yield of various crops, a lot of information reported at home and abroad. Our school in 1987 ~ 1988 carried out rare earth fertilizer on corn fertilizer efficiency research. After two years of field trials, it was initially believed that the dressing and spraying of maize with rare earth and micro-fertilizer could promote plant growth, regulate the development of various organs, alleviate the contradiction between plant vegetative growth and reproductive growth, and increase the number of grains per spike, grain weight and yield. Application of rare earth fertilizer also has less dosage, low cost, the application of simple technology features. First, the test materials and methods
