| 摘 要： | 通过三个3个不同养分水平土壤上菜心氮、磷、钾"3414"田间试验,所获得的3种肥料效应方程,求取最佳施肥量。结果显示:(1)净收入最多的处理,3个试验均基本是中等水平或1水平的处理,说明试验设计水平合理。(2)3个点肥料试验的一元二次效应方程中,均是N效应的显著度最高、P效应的显著度次之、K效应的显著度最差;二元二次效应方程中只有NP效应的显著度是3个试验均较高的,NK效应则只有2个试验的显著度相对较高而PK效应则仅有1个试验的显著度相对较高;3个试验的三元二次效应方程中只有2个试验的显著;但这属于显著的2个当中又有1个的N、P、K全是负效应。(3)氮、钾肥理论最佳施肥量的高或低,基本与试验地土壤碱解氮和速效钾含量水平相吻合;磷肥的理论最佳施用量和试验中产量较高处理的施用量不与试验地土壤速效磷含量水平相吻合,而与土壤pH值有关。

| Abstract: | Flowering Chinese cabbage (Brassica parachinensis Bailey) was a main vegetable in south China.The field tests were carried out to study fertilizer effects of nitrogen,phosphorus and potassium 3414fertilizers on Flowering Chinese cabbage in three soils with different fertility levels.The results showed that:(1) The best excellent treatment was mid level or low level basically in three tests,that showed the level of test plans were right.(2) The significance of unitary quadric equations in nitrogen effect was... |
