【摘要】 采用通用旋转回归组合设计方法,研究了山西省石灰性褐土上施用钾、锌、锰肥对青椒根系活力、叶绿素含量及产量的影响。结果表明:在氮、磷肥底的基础上,施用钾、锌、锰肥有利提高青椒根系活力和叶片的叶绿素含量并最终提高青椒的产量,三种肥料的增产效果为钾>锰>锌。在本试验条件下青椒产量高于75000kghm-2的钾、锌、锰肥施肥方案为每hm2施用氯化钾570~712kg、硫酸锌81.6~119.4kg、硫酸锰105.9~133.7kg。

【Abstract】 The experiment was conducted on calcareous cinnamon soil of Shanxi Province with design of ordinary second order rotational regression of three factors. Under the condition of field experiment, combined application of Potassium chloride, Zinc sulfate and Manganese sulfate to green pepper was studied for it effects on the yield and quality. The results were concluded as follows:(1) Root activity and Chlorophyll content of green pepper were improved to certain extent by combined K, Zn and Mn fertilizer. (2) In case of single application and on the basis of P and N, the effect of K, Zn, Mn on green pepper yield was K> Mn > Zn. (3)Under the condition of this experiment the optimum application rates were: Potassium chloride 570-712 kg hm-2, Zinc sulfate 81.6-119.4 kg hm-2, Manganese sulfate 105.9-133.7 kg hm-2.
