继M系和MM系矮化砧之后,我国于80年代初又引进了CG系苹果矮化砧,为了探明其生产效应,我所于1986-1991年,以CG系的不同砧号与M26、MM106矮化中间砧的青富13苹果树进行了栽培比较试验,现将初步结果简结如下。1 试材和方法试材均以平邑甜茶为基砧;参试的中间砧有CG23、CG24、CG55、CG57、CG80,对照中间砧为M26和MM106,中间砧砧段长度均为25cm;嫁接品种均为青富13。参试的中间砧苹果苗均于1986年春定植,行株距为3m×2m,折合每公顷栽植1666.7株。试验园为平地,粘壤土,0-40cm土层含有机质
Following the M system and the Department of MM dwarfing anvil, our country in the early 1980s and the introduction of the CG apple dwarfing anvil, in order to prove its production effect, I in 1986-1991, the CG anaerobic and M26 , MM106 dwarfing intermediate anqing 13 apple trees were compared with the cultivation test, the preliminary results are summarized as follows. 1 The test materials and methods The test materials are based on the sweet potato as an anvil rootstock; the test intermediate anvil with CG23, CG24, CG55, CG57, CG80, the control intermediate anvil M26 and MM106, the anvil anvil section length of 25cm; Variety are green 13. The apple seedlings were all planted in the spring of 1986 with an interval of 3m × 2m, equivalent to 1,666.7 plants per hectare. Test garden is flat, clay loam, 0-40cm soil contains organic matter
