施N量与插植密度对玉丰占产量的影响

采用2因素3水平随机区组设计，在广西北流市民安镇才旺村百亩连片中试示范区进行玉丰点不同施N量、插植密度试验，以探讨施N量、插植密度对玉丰点产量的影响。结果表明，施N量、插植密度、施N量×插植密度之间有显著的产量差异，30万穴／ha插植密度需要纯N180kg／ha和纯N210kg／ha的施N水平，24万穴／ha插植密度需要纯N210kg／ha的施N水平，36万穴／ha插植密度需要纯N150kg／ha的施N水平才能获得较高产量。

Effects of different nitrogen applications and planting densities on yield of rice variety Yufengzhan

To study the effects of nitrogen application and planting density on the yield of rice variety Yufengzhan, different nitrogen applications and planting densities have been evaluated in randomized block design using two factors and three levels in 100-mu demonstration region at Caiwang village, Beiliu City, Guangxi. The results showed that nitrogen application, planting density and nitrogen applicationxplanting density had significant effects on the yield of rice variety Yufengzhan. Nitrogen appilication of 180 and 210 kg/ha with 300 thousand hills per hectare of planting density, 210 kg/ha nitrogen with 240 thousand hills per hectare and 150 kg/ha nitrogen with 360 thousand hills per hectare, were found to be increase the yield significantly.
