Abstract
Taking 2-year-old Camellia oleifera seedlings from the state-owned Bobai Forest Farm in Guangxi as the research object,different concentrations of nitrogen,phosphorus,potassium,and trace elements were used to determine the growth indicators and nutrient content of root,stem,and leaf parts during the grafting seedling stage.The characteristics of different leaf fertilizers on the growth and nutrient absorption of Camellia oleifera seedlings were studied.The results showed that different foliar fertilizer treatments had a significant impact on the nutrition-al growth of Camellia oleifera seedlings,and foliar fertilizer had a significant fertilizer effect on Camellia oleifera seedlings.Treatment⑦ had the highest increase in net leaf growth compared to the control,reaching 47.16%.Treatment ⑧ had the highest nitrogen content,which in-creased by 170.89%compared to the control.In terms of trace elements,treatment⑧showed the highest increase in magnesium content com-pared to the control,with an increase of 101.47%.The demand pattern for nutrients during the seedling stage of Camellia oleifera was N>K>P.Research had shown that when the ratio of nitrogen,phosphorus,and potassium was 10∶15∶6 and the spraying concentration was 2.5%,it can significantly promote the growth of seedlings compared to the control.关键词
