腐殖酸载体微肥组合研究

STUDY ON THE EFFECTIVENESS OF COMBINATED-FACTOR OF MICRONUTRIENTS AND HUMIC ACID ON THREE CROPS

采用2次通用旋转组合设计,通过单因素、组合因素、边际等效应解析,筛选出小麦、水稻、玉米对腐殖酸和硼(B)、钼(Mo)、锌(Zn)微肥的组合效应分别为:B·Mo>2B>2B·Mo/Zn,Zn·2B/腐殖酸>2B>Zn·B,2Zn>Zn·B>2Zn·B/腐殖酸.

The models of micronutrients combinated with humic acid(HA)with wheat,rice andmaize were selected respectively as B·Mo>2B>2B,Mo/Zn,Zn·2B/HA>2BZn·B,2Zn>Zn·B>2Zn·B / HA.The above models were obtained by analyzing thesingle factor,combinated factor and marginal effect of micronutrients and humic acidbased on the results of field experiments.A normal square rotary design was employed inthis study.
