摘  要：
分别在2013,2014年,设置5个施脱硫石膏量水平(T1,T2,T3,T4,T5)和3个种植密度水平(M1,M2,M3),研究了在苏打盐化潮土上施脱硫石膏量和种植密度对玉米产量及相关性状的影响。结果表明,脱硫石膏不同施用量对玉米出苗率、成苗率、产量及产量构成的千粒质量、穗粒数等的影响均达到显著差异水平,而且随着脱硫石膏施用量增加,除空秆数外其他都是先增加后降低,产量大小排序为T4>T3>T5>T2>T1;提高种植密度,显著影响玉米产量、空秆数、穗粒数、千粒质量,产量大小排序为M2>M3>M1;种植密度与施脱硫石膏量相互作用对玉米产量、空秆数、穗粒数的影响均达到显著差异水平,2 a玉米产量及相关性状变化趋势一致;综合考虑脱硫石膏量和种植密度二因素,利用2 a数据拟合最优二元二次方程,推导出2013,2014年玉米产量最高时对应的种植密度、脱硫石膏用量分别为69 268株/hm2,16 094 kg/hm2和68 277株/hm2,15 762 kg/hm2。

摘  要：
In 2013, 2014, respectively, this paper set up five of the desulfurization gypsum application levels(T1, T2, T3, T4, T5), and three planting density levels(M1, M2, M3), and studied the effect of in desulfurization gypsum quantity and planting density on corn yield and related traits soda fluvo-agvic salinization soil. The results showed that the desulfurization gypsum applying different content of maize emergence rate, seedling rate, grain yield and yield components of 1 000 grain quality, grain number per ear, and so on significant differences were the influence of the level, and with the increase of applying the desulfurization gypsum content, apart from the empty pole number first increased then decreased. The orde of the size of the yield was T4>T3>T5>T2>T1. Improve planting density, significantly affect the output of corn, empty pole number, grain number per ear. The orde of the size of the yield was M2>M3>M1. Planting density and interaction of desulfurization gypsum application on corn yield, the influence of the empty pole number, grain number reached significant difference levels. Two annual corn yield and related traits change trend was consistent. Under this experimental condition,considering the desulfurization gypsum quantity and planting density of two factors, using two annual data fitting of the optimal binary quadratic equation and maize yield was the highest when the corresponding planting density deduced, the dosage of desulfurization gypsum 2013, 2014 respectively 69 268 plants/hm2, 16 094 kg/hm2 and 68 277 plants/hm2, 15 762 kg/hm2.
