Study on formula fertilization for container seedlings of rare species Ormosia henryi
摘要
Abstract
According to the "3414" experiment design,the fertilization experiment with the different combination of N,P and K for Ormosia henryi Prain container seedlings was conducted,the growth and physiological indexes were measured.The results indicated that the growth indexes (height,diameter,root and biomass etc.) and the physiological indexes (including photosynthetic rate,light use efficiency,water use efficiency,chlorophyll content,nitrate content,nitrate reductase activity and root activity) of O.henryicontainer seedling were greater than CK after fertilization treatment,and the difference between different treatment was significant.Among 14 treatments,the height,diameter,average root diameter,total root volume,≥5 cm lateral root number,total biomass,photosynthetic rate,chlorophyll a of 6#(N2P2K2) seedlings showed the best performance which is the 1.66,1.33,6.10,3.90,6.00,2.26,2.10,2.52 times compared to the control.The fertilization model showed that the best fertilization formula was recommended by N 1.41 g,P 0.44 g and K 0.29 g for each O.henryiseedling.关键词
