上海郊区的巨峰葡萄由于落花较重,产量低而不稳。本研究采取综合性技术措施,控制和稳定树势,在篱架密植的条件下取得连年丰收。4—6年生巨峰平均年产40470公斤/公顷:3—4年生巨峰年产每公顷26250—39078.75公斤;绿苗定植的2年生巨峰达21270公斤/公顷。本文总结和提出了丰产园的树相诊断、产量与质量。叶面积系数、修剪结构等技术指标。发现副梢结果母枝的结实力优于主梢母枝,培养副梢作为结果母枝是提高巨峰葡萄产量的重要途径。
Shanghai Kyoho grapes because of falling heavier, low yield and instability. In this study, comprehensive technical measures were adopted to control and stabilize the tree vigor and achieve annual harvest under the close planting conditions. 4-6 year old Kyoho average annual output of 40,470 kilograms / hectare: 3- to 4-year-old Kyoho 26250-39078.75 kilograms per hectare per year; green seedlings planted 2-year-old Jufeng reached 21270 kilograms / hectare. This paper summarizes and proposes the tree-crop diagnosis, yield and quality of high-yielding garden. Leaf area coefficient, trim structure and other technical indicators. The results showed that the fruiting branch of fruiting branches was better than that of main shoots, and the secondary shoots were the main ways to increase the yield of giant grapes.
