1982年我们对东升农场第七生产队1970年冠接的PR107三合树,进行了第七年的产量测定,测产组合五个,其中93～114/PR107组合7株,平均树围(离地150厘米处,下同)63.1厘米8～673/PR107组合6株,平均树围58.5厘米;五星I_3/PR107组合6株,平均树围59.0厘米;联昌20～25/PR107组合5株.平均树围46.6厘米;白南28～32/PR107 8株,平均树围51.3厘米,对照(PR107)24株,平均树围51.5厘米.测产从5月开始到11五月止,采用常规割制(s/2、d/2、100%),逐刀量胶水,测干合,抗干胶,全年测产80刀,测产结果93～114/PR107组合平均年株产干胶4.32公斤8～673/PR107组合2.68公斤;
In 1982, we measured the yield of the seventh PR107 seedlings of the seventh production team of Dongsheng Farm in 1970 and measured the production in five combinations. Among them, there were 7 combinations of 93-114 / PR107 and the average tree circumference PR107 63.1 cm 8 ~ 673 / PR107 combination of six, the average tree circumference 58.5 cm; five-star I_3 / PR107 combination of 6, the average tree circumference of 59.0 cm; Cichang 20 ~ 25 / PR107 combination of five. Average tree circumference 46.6 cm; White South 28 ~ 32 / PR107 8 strains, the average tree circumference 51.3 cm, the control (PR107) 24 strains, the average tree circumference 51.5 cm. Measured from May until May 11, the conventional cut (S / 2, d / 2, 100%), by the amount of glue, dry measured together, anti-dry glue, the annual test 80 knife, the test results 93 ~ 114 / PR107 combination of the average annual dry weight 4.32 Kg 8 ~ 673 / PR107 combination of 2.68 kg;
