采用田间小区试验,研究了种植密度和施肥水平对湘杂油763氮磷钾养分吸收和子粒产量的影响。结果表明,在相同种植密度条件下,高施肥处理的产量明显高于低施肥处理,且4个施肥水平间产量的差异达到显著或极显著水平;高施肥而种植密度小和低施肥而种植密度大的处理产量相对较高。所设的24个处理中,产量最高为2696.15千克/公顷(施氮肥180千克/公顷、施
Field experiment was conducted to study the effect of planting density and fertilization level on N, P, K uptake and grain yield of Xiangzaoyou 763. The results showed that under the same planting density, the yield of high fertilization treatment was significantly higher than that of low fertilization treatment, and the difference of yield between the four fertilization levels reached significant or extremely significant level. High fertilization with low planting density and low fertilization and planting density Large processing output is relatively high. Of the 24 treatments provided, the highest yield was 2696.15 kg / ha (nitrogenous fertilizer 180 kg / ha
