为了鉴定稀土微肥在我市土壤,耕作管理条件下对红麻的增产效果及施用技术,我们于1985年进行了试验研究,现将结果报道于后。一、试验材料和方法供试稀土肥料为河南商丘冶炼化工厂生产的硝酸稀土,红麻品种为“7804”,试验地土壤为红壤旱地,前作为甘蓝型油菜,地势较高,排灌不便,土壤耕层较浅。试验设喷施稀土与不喷施(对照)2个处理,3次重复,小区面积为0.01亩,对比排
In order to identify rare earth fertilizer in the city soil, tillage management conditions of kenaf yield and application of technology, we conducted a pilot study in 1985, the results are reported later. First, the test materials and methods for testing Rare earth fertilizers for Henan Shangqiu smelter chemical plant production of rare earth nitrate, kenaf varieties for the “7804”, the test soil is red soil arid, formerly as a Brassica napus, high terrain, irrigation and drainage inconvenience, soil Sowing shallow. Test set of spraying rare earth and spray (control) 2 treatment, 3 times repeated, plot area of 0.01 acres, contrast row
