【摘要】 为了确定香稻品种桂香占施肥方案,探讨不同施肥水平与各个影响产量、品质的因素之间的关系,采用了施用氮、磷、钾和硅对桂香占产量及品质影响。在α=0.5显著水平剔除不显著项后,分析结果显示尿素、过磷酸钙、氯化钾、Na2SiO3.9H2O分别施用26,0,48,56 g/m2时,产量达最大值5 352.6 kg/hm2。单因素中对产量影响:P>N,且K,Si无影响。互作因素影响中:K与Si互作(产量与之正相关)>P与K互作(产量与之负相关)>P与Si(产量与之负相关)。更多还原

【Abstract】 In order to account for project of fertilization Guixiangzhan,and probe into relationship of different levels of fertilizer application and effect of various factors of production and quality.This thesis studied on the effects of the usage of massive elements which included nitrogen,phosphorus,Potassium and silicon on yield and quality of Guixiangzhan.After delete the unapparent factors under α =0.5 level,the analytic results showed that when the usages of Urea,Super phosphate,Potassium chloride and Sodium silicate were 26,0,48,56 g/m2,the maximum yield was 5 352.6 kg/ha.The influences to the yield in single factors are P>N,and K,Si have little influence under α =0.5 level;The influences to the yield in compound factors are:the product of K and Si has a positive effect on yield > the product of P and K has a negative effect on yield> the product of P and Si has a negative effect on yield.Besides,the relativities of each factor are calculated.更多还原
