以九头狮子草为研究对象,采用N、P、K 3因子3水平(L9(33))正交实验,研究了不同施肥水平对九头狮子草营养生长和开花的影响。结果表明:与对照相比,不同N、P、K水平处理明显加快植株的生长和正常开花,并且开花时间提前约1周,其中最利于植株营养生长和开花的施肥组合为N1P2K2。N是影响植株生长的主要因素,其次为P、K;K是影响植株矿质元素吸收的关键因素,它们与植物叶片全氮、磷、钾、镁含量呈正相关;其次为P,它与植物P和K含量呈正相关。
Nine lions were used as research object to study the effects of different fertilization levels on the nutrition growth and flowering of Hydrangea gossypii by N, P, K 3 factor 3 (L9 (33)) orthogonal experiment. The results showed that compared with the control, the treatments of different N, P and K levels significantly accelerated the plant growth and normal flowering, and the flowering time was about 1 week ahead of schedule. The most suitable combination of plant growth and flowering was N1P2K2. N is the main factor affecting the plant growth, followed by P, K; K is the key factor affecting the mineral element absorption of plants, and they are positively correlated with the total nitrogen, phosphorus, potassium, magnesium content of plant leaves; followed by P, And K content was positively correlated.
