施肥对扶芳藤产量及养分吸收特性的影响

Effect of fertilization on the yield and nutrient uptake of Euonymus fortunei(Turcz.) Hand.Mazz.YANG Rui-qing1

田间试验表明,不同施肥处理均可提高扶芳藤产量,增幅为58%～87%;增施氮肥能显著提高扶芳藤对氮素的吸收,而增施磷、钾肥,扶芳藤吸收磷、钾素的增幅不高;每生产1000kg鲜扶芳藤需吸收N 4.088～5.672kg、P2O51.573～1.802kg、K2O 2.544～4.517kg;扶芳藤对养分的吸收基本保持平缓均衡的趋势,在养分供给上可根据实际情况均衡施肥,就能保持扶芳藤正常生长。

Through field trials, it showed that different application of fertilizer could increase 58%-87%of the yield of Euonymus fortunei. Applying nitrogen fertilizer could significantly increase the absorption of nitrogen, but the absorption of phosphorus and potassium could not significantly increased by increasing phosphorus and potassium fertilizer. It needs to absorb nitrogen 4.088-5. 672 kg, P2O5l. 573-1. 802 kg, K20 2. 544-4. 517 kg to produce 1000kg fresh Euonymus fortunei. The absorption of nutrients for Euonymus fortunei was maintaining a balanced trend, so the supply of nutrients can be balanced according to the actual situation that will be able to maintain normal growth.
