金银花优良品种‘舜帝1号’施肥技术研究

Fertilization technique of a fine variety-Lonicera japonica‘Shundi 1'

本试验系统研究了施肥对金银花优良品种"舜帝1号"产量的影响,筛选出适宜的有机肥、复合肥及氮磷钾配比肥施肥量。结果表明:3年生金银花树有机肥施用量以2.0 kg/株为宜,第一茬花单株干花产量达0.213 kg。复合肥以氮磷钾总养分≥52%、N—P2O5—K2O=25-9-18的复合肥增产效果最好,用量以0.5 kg/株为宜,第一茬花单株干花产量达0.249 kg。氮、磷、钾肥对金银花增产作用大小顺序为:氮肥>磷肥>钾肥,氮、磷、钾肥施用量分别以0.10、0.20、0.10 kg/株为宜,比不施肥的金银花干花产量提高88.8%。

The effects of fertilizer on yields of Lonicera japonica‘Shundi 1＇were studied,in order to acquire the optimal use of organic fertilizer,compound fertilizer N and P and K proportion fertilizer. The results showed that,the optimal amount of organic fertilizer was 2. 0 kg per plant,the yield of the first- cut dry flower of 3-year-old plant was 0. 213 kg per plant. The suitable compound fertilizer was N,P and K contents greater than or equal to 52%（ N — P2O5- K2 O = 25- 9- 18）,the yield of the first-cut dry flower reached 0. 249 kg per plant when the fertilizer rate was 0. 5 kg per plant.The yield-increase effect on Lonicera japonica ‘Shundi 1＇of nitrogenous and phosphate and potassium fertilizer followed the order nitrogenous phosphate potassium,and the optimal amount of proportion fertilizer were 0. 10,0. 20,0. 10 kg per plant respectively,which could increase the yield by 88. 8% than the control.
