应用土壤养分状况系统研究法测定土壤中11种大、中、微量元素含量,结合土壤对营养元素的吸附研究和盆栽试验,认为菜地土壤中氮、钾、锰是主要的养分限制因子。田间试验补足该养分,能改善茄子的农艺性状,提高茄子产量。
The contents of 11 kinds of trace elements in the soil were determined by systematic study of soil nutrient status. Combined with the study on nutrient adsorption and pot experiment, it was concluded that the nitrogen, potassium and manganese in the vegetable soil were the main nutrient limitation factors. Field trials make up the nutrients, can improve the agronomic traits of eggplant, eggplant yield increase.
