绥李3号密植高产栽培试验

Close Planting-High Yield Cultivation Test of Prunus salicina cv. Suili No.3

通过密植高产栽培试验,对不同栽植密度下绥李3号的果实产量进行了对比分析。结果绥李3号栽植后三年生至四年生平均每年公顷产量以每株占地面积0.60 m2(株行距0.15 m×4.00 m)的为最高,是每株占地面积3.60～4.50 m2的2倍多,是每株占地8.00、10.00 m2的4～7倍多,其次是每株占地面积3.75m2(株行距1.50 m×2.50 m)的。绥李3号早期高产,田间种植密度以行距4.00 m、株距0.30、0.50、0.75 m的株行距为宜,但在建园时一定要栽大苗、合理配置授粉树、采用隔年或隔枝短截与缓放的修剪方法、加强肥水管理、有效防治病虫害才能获得早果丰产。

Through close planting-high yield cultivation test,the fruit production yield of Prunus salicina Lindl.cv.Suili No.3 with different planting density was analyzed.The results showed that the average annual yield of 3-year-old to 4-year-old P.salicina cv.Suili No.3 after planting was the highest when the area per plant was 0.60 m2(planting space 0.15 m ×4.00 m),which was more than twice of those with area per plant at 3.60 m2 to 4.50 m2;4～7 times of those with area per plant at 8.0 m2 and 10.0 m2;the yield of plant with area per plant at 3.75 m2(planting space 1.50 m × 2.50 m) ranked the second.P.salicina cv.Suili No.3 was with early and high yield.The proper planting density in field was line space,4.00 m while individual space,0.30,0.50 or 0.75 m.However,early fruit and high yield could only be obtained by planting big seedling when constructing the orchard,reasonably allocating pollination tree,pruning in the way of cutting and slow releasing every two years or at interval branches,enhancing water management,controlling and preventing plant diseases and insect pests effectively.
