肥料用量与种植密度对春玉米产量及效益的影响
Effects of Fertilizer and Planting Density on Yield and Benefit of Spring Maize
摘要
Abstract
Using split plot design, studied the effects of different maize special fertilizer(STANLEY compound fertil-izer) and planting densities on the yield and economic benefit of Spring Maize Zhengdan 958, the results showed that the yield increased at first and then decreased with the increase of fertilization amount, in A2 treatments were the highest (750kg/ha2), 15.86t/ha2; the yield with the increasing of planting density increased at first and then de-creased, in B3 treatments were the highest(7.5million lines/ha2), 16.31t/h2; Refer to the benefit of pure increase yield on density and fertilizer treatment combinations, A3B3 treatment(900kg/ha2,7.5million lines/ha2)was the high-est, A2B3 treatment (750kg/ha2,7.5million lines/ha2) was the second, the benefits of pure increase yield were 12600.00yuan/ha2 and 12440.00yuan/ha2 respectively; A3B3 treatment combination had the best overall perfor-mance in the comprehensive yield and benefit analysis, which could be widely applied in the test area.关键词
