Path Analysis of Climate Factors and Bolls Per Plant in Suqare-boll Stage of Cotton in Liaocheng

Abstract

Abstract: According to the path analysis, sunshine duration of August, precipitation of July and August, and mean temperature of July were the main climatic factors that influenced the bolls per plant of cotton directly in Liaocheng, while sunshine duration of August, average temperature of July and June were the indirect factors. It was favorable for increasing the bolls per plant of cotton to improve the microclimate such as sunshine, temperature and water appropriately by pruning and controlling chemically.

Key words: Climate factor, Climate factor, Bolls per plant, Path analysis
