Culture tender leaves in culture medium of MS+2,4-D1.5mg/L+30g/L suger+0.7% agar pH5.8 for 20 days in darkness at 25℃, and then subculture to induced Ⅱ-type calli. Use forceps cutting the tissue to nubble with 2mm2, and put the tissue into Agrodacterium tumefaciens LBA4404 liquid supplemented with AS 100mg/L,then, co-culture 3 days, resume 7 days in MS+2,4-D1.5mg/L+30g/L suger+500mg/L cef, take to MS+2,4-D1.5mg/L+30g/L suger+100mg/L cef+10.0mg/L kanamycin culture 20 days in darkness. After that to make it polarize in MS+30g/L suger+100mg/L cef+10.0mg/L km. The percentage of km resistant callus was reached max after infection for 45 min, the average is 29.66%. Simultaneity, tender leave callus are infected 5 min by A. tumefaciens liquid in different negative pressure, and kept on 15 min in Agrodacterium tumefaciens liquid without negative pressure. Then screen out resistant callus and obtain transgenic plants. When the negative pressure is -0.05MP the percentage of km resistant callus was reached max, the average rate is 37.5%.

However, the transformation rate from dominant stem to overtopped stem and from overtopped stem to dominant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gmelinii was going up. The altitude that classified stem mainly concentrated was less than 1000m, slope was less than 25°, aspect was south slope, position was at middle and lower, soil depth less than 17cm. The rate of no interconversion was 66.7% among overtopped stem. It should cut the overtopped stem as intermediate cutting.

优势木转被压木和被压木转优势木的转换率最低；随着林分密度和林分中落叶松比例增加，分级木相互转换数也增多；分级木转换现象主要集中在海拔＜1000m、坡度＜25°、坡向为阳坡、坡位为中下、土壤厚度＞17cm的林分中；被压木中，无转换的占66.7%，抚育采伐时应考虑伐除这些被压木。

Stopped running in the system, the entire network piezometer head has reached the same trend, while reducing the differential pressure control valve through the opening best to maintain the original pressure has remained basically unchanged until the differential pressure control valve closed.

在系统停止运行时，整个网路的测压管水头有达到一致的趋势，而压差控制阀则通过减小开度竭力维持原有的压差基本不变，直至压差控制阀关闭。
