不同肥料增效剂对小麦生长发育的影响

Effects of Different Fertilizer Synergists on the Growth of Wheat

为探究不同肥料增效剂对作物生长发育的影响,以小麦为研究对象,通过水培及盆栽试验,研究施用不同肥料增效剂对小麦生长发育的影响。结果表明:抗50度硬水腐植酸钾粉剂处理最有利于小麦的生长发育,能够促进小麦苗期地上部株高、生物量积累和根系的生长发育,促进冬后返青期分蘖数增加和株高生长;增加小麦穗数、穗粒数、千粒重,提高产量;降低土壤pH,增加土壤有机质、硝态氮、速效钾含量。

In order to explore the effects of different fertilizer synergists on the growth of crop,through hydroponic and potted experiments,the effects of different fertilizer synergists on the growth of wheat were studied.The results showed that the treatment of resistant to 50° hard water potassium humate powder was most beneficial to the growth of wheat.It could promote the above-ground plant height,biomass accumulation and root growth of wheat seedling,increase the number of tillers and promote the growth of wheat plant height at returning green stage.It could increase the number of wheatears and grains per ear and 1000-grain weight,thereby increasing yield.It could reduce soil pH and increase soil organic matter,nitrate nitrogen content and available potassium content.
