摘    要:采用田间试验方法在温室大棚土壤上进行了钾肥品种与用量对茄子养分吸收的影响试验。研究结果表明:钾肥可提高茄子养分元素的含量,但不同钾肥品种和用量的影响有一定差异,氯化钾处理茄子氮、钾、钙含量比硫酸钾高。钾肥也可提高茄子微量元素含量,硫酸钾处理铁、锌含量比氯化钾高。钾肥明显提高了茄子大、中量养分元素的吸收量,氯化钾对养分有明显的富集作用,富集部位与养分在植株体中分布特性密切相关。钾肥可提高养分元素茄子营养体中的分配比例。钾肥品种在提高茄子养分吸收利用上差异与产量和品质有明显的相关性。

关 键 词:温室大棚  土壤  钾肥  品种  使用量  茄子  养分吸收  影响因素

Abstract:The field trial of effect of K types and dose on the nutrient uptake of eggplant grown on the soil under greenhouse was conducted out. The results indicated that the potassium could increase the concentration of nutrients, but the effect of K types and dose on the element content in vegetative tissues and fruits of eggplant varied. The N, K and Ca contents in eggplant with KCl (MOP) were higher than that with K 2SO 4(SOP). K also increased the microelement content of eggplant. The Fe, Zn contents in eggplant with SOP were higher than that with MOP. Application of potassium enhanced the uptake of macro- and secondary nutrients by eggplant The nutrient uptaked by eggplant with MOP were larger than that with SOP which implied that the MOP could enrich the nutrients in eggplant. The part where the nutrient enriched was correlated with the partition pattern of different elements in plant. K could raise the nutrient partition in vegetative tissues.The differences between K type in nutrient uptake had obvious influences on the yield and quality of eggplant fruit.
Keywords:K type and K dose  greenhouse  eggplant  nutrient uptake
