摘要
以6个苹果品种为试材,进行苹果的有效负载面积与产量相关性试验。结果表明:在一定条件下,有效负载面积(EBS)越大,产量相应越高。不同纬度对不同品种的EBS和产量的影响不同。土壤中砾石含量对EBS和产量都有影响,但品种和砧木不同,EBS的减少率不同。不同品种对砾石的耐受能力不同。
Took 6 apple varietis as material to study the connection of effective bearing surface (EBS) and production. The results showed.the bigger EBS, the higher productions Different latitude had different affection on EBS and production of different vareties. Gravel condition of Soil could affect EBS and production, the reducing rate of EBS was influnced by, varirties and rootstocks. Different varieties had different tollerane to gravel.
