Abstract

Abstract: Using Danyu202 as experimental materials,we studied the effect of the interaction of four kinds of different chemical regulators and four kinds of different dose of potassium fertilizer on morphological index and yield of maize in southern Liaoning Province.The result indicated that the Corn Zhuangfengling interacted with four kinds of different dose of potassium fertilizer could effectively decrease plant height,increase layer number of aerial root;the interaction between Yuhuang V8 and four kinds of different dose of potassium fertilizer effectively shortened internode distance,increased stem diameter,decreased lodging rate and breaking rate;K2SO4 112.5 kg/ha and Corn Fengzhuangling combined yield maximum 11 120.40 kg/ha.

Key words: Chemical regulation, Potassium fertilize, Interaction Yield
