摘要
应用壕沟法研究了利用矮化中间砧栽培不同定植方式 (中间砧全部露出地面与中间砧 1 /2露出地面 2种 )对苹果树根群分布、根系的鲜重、干重及枝、干、叶、果的鲜重、干重等的影响。结果表明 ,2种不同定植方式根群 90 %以上分布在 0～ 40 cm土层中 ,其中 2 0～ 40 cm土层中分布最为集中 ,分别占总根量的 5 9%和 5 5 %。水平分布以主干为中心 ,主要集中在中间砧露出区株间 60 cm以内 ,中间砧 1 /2露出区株间 80 cm以内 ,行间无明显差异。根系的鲜重和干重中间砧 1 /2露出区是中间砧露出区的 1 .34倍和 1 .78倍 ,枝、干、叶、果实的干重中间砧1 /2露出区是中间砧露出区的 2 .4倍、2 .3倍和 2倍 ,果实产量二者相比 ,中间砧 1 /2露出区较中间砧露出区提高了 2 8.5 %。
With the method of ditching,affection of dwarfing apple trees in different planting patterns on root system distribution, fresh weight and dry weight of shoots,stems,leaves and fruits was studied. It is proved that both interstock exposed and half buried could cause over 90% of root system distributing into 0～40 cm soil layer, and mainly concentrating in 20～40 cm deep, taking 59% and 55% of the total root weight respectively. The moisture distributed around the trunk. and mainly concentrated less 60cm area between interstock exposed,while less 80 cm interstock half buried. There was no obvious difference in the row spacing.The fresh weight and dry weight of interstock half buried area were 1.34 times and 1.78 times the weight of the interstock exposed respectively,compared the dry weight of shoots,stems,leaves and fruits with interstock half buried and interstock exposed, the former is 2.4 tmies, 2.3 times and 2 times the weight of latter, the comparistion of fruit yield was that the interstock half buried increased 28.5% than those exposed.
