麦饭石矿物肥施用效果试验

摘要

通过盆栽种植小白菜及后茬作物苋菜,测定其农艺性状、产量及植株中矿质营养成分含量来研究麦饭石矿物肥肥效.结果表明,麦饭石矿物肥对小白菜和苋菜的茎长、根长、鲜重和矿质元素的积累均有显著影响；当矿物肥的施用量在0～0.87g·kg-1时,随着矿物肥施用量的增加其作用明显增强,当大于0.87g·kg-1时,其增效减缓.%By pakchoi and subsequent crop Amaranthus test, determination of its agronomic traits, yield and mineral nutrient content to study on efficiency of maifanitum mineral fertilizer. The results showed that the stem length, root length, fresh weight of agronomic traits and content of mineral elements of pakchoi and amaranth were significantly affected by the maifanitum mineral fertilizer; When the mineral fertilizer usage in 0 ~0. 87 g · kg-1, the action to pakchoi or amaranth increased apparently with the mineral fertilizer increase, when greater than 0. 87 g · kg-1, its promotion efficiency was slow.
