Effects of Different Planting Densities on Stalk Lodging Resistance of Maize
Taking Mengcheng area of Anhui Province as the test site,the effects of different planting densities on stalk toppling resis-tance of maize were studied.The results showed,moderate planting density could increase maize plant height and thousand grain weight,but had little effect on ear diameter and ear length.Improper planting density may reduce yield and quality.The adjustment of planting density also affected the vacancy rate and lodging rate,and the appropriate density decreased the vacancy rate and in-creased the actual yield.Moderate decrease of density can reduce lodging rate and improve lodging resistance.However,high densi-ty planting may increase lodging rate and threaten yield and quality.
