种植密度和氮肥水平对花生产量的影响
The Effects of Density and Nitrogen Levels on the Peanut Yield
摘要
Abstract
Under field condition, randomized block design of two factors (planting density and ni-trogen fertilizer) at three levels (high, medium and low) was executed to study the interaction of ni-trogen fertilizer and planting density on peanut yield, so as to provide guidance on the high yield pea-nut group construction and efficient cultivation.The results showed that the chart of regression equa-tion was the saddle shape, which the yield increased at first and then decreased with the increase of ni-trogen applying amount at high or low planting density condition.The yield was the highest at medi-um nitrogen fertilizer applying amount.It showed that high yield can be obtained with the levels of high-density and medium topdressing of nitrogen fertilizer.Therefore, it had obvious interaction be-tween planting density and topdressing nitrogen fertilizer amount on peanut yield.关键词
