不同氟添加量对油菜生长及土壤化学性状的影响
Effects of Fluorine Quantity on Rapeseed Growth and Soil Chemical Properties
摘要
Abstract
Objective] To discuss the effects of fluorine quantity in fertilizers on rapeseed growth and soil chemical properties.[Method] Rapeseed pot test was adopted.Rapeseed yield, quality, growth characters and soil chemical properties under different fluorine quantities were compared.Thus, the fertilizer fluoride threshold for restricting the rapeseed growth was obtained.[Result] Adding fluoride to fertilizer could inhibit rapeseed growth and the amount of 200 mg/kg was the critical value.When exceeding this threshold, the rapeseed yield decreased by 27.38%-37.82%.With the increase of fluoride dosage, rapeseed protein content, oil content, soluble sugar content decreased.Compared with adding no fluoride, and the critical values of fluorine quantity was 300, 200 and 100 mg/kg, respectively.The root activity of rapeseed decreased by 12.04% -41.83%, and the difference was significant on fluorine application, and the chlorophyll content decreased by 19.09%-32.11% of 300-500 mg/kg fluorine application.The soil total fluorine content increased significantly when fluorine application was greater than 300 mg/kg, and this quantity exceeded the rapeseed growth fluoride threshold, but the soil pH enhanced by 3.56% -7.73%.[Conclusion] Fluoride content in fertilizer should not be more than 300 mg/kg.关键词
