大樱桃壮旺幼树不同修剪方法和促花技术试验

为了研究整形修剪对大樱桃早期丰产的影响，通过稀植园和密植园大樱桃壮旺幼树的修剪试验，明确长放修剪方法可节省用工，有利于树体生育，成花早、株产高，尤其适用于密植园的大樱桃栽培。开始采用长放修剪的树龄，密植园大樱桃树宜在2～3年生，稀植园樱桃树宜在株问粗距1．5～2m时进行，截放修剪方法适用于即需扩冠又要较早结果的大樱桃壮旺幼树。短截修剪方法修剪量大，不利于大樱桃壮旺幼树的生长发育，结果晚，株产低，且费工，但对栽后缓苗期树或衰弱树还是适用的。刻芽枝条上叶丛皲数量明显增加，花束状果枝增加。摘心的长枝花枝率和后下部叶丛枝的花枝率明显增加。

Cherry Strong Saplings of Different Pruning Methods and Promoting Blossom Test Conclusion

in order to study the effect of Pruning on Cherry high-yield, Luoyang Academy of agriculture and forestry large cherry group by dilute pruning test plantation and close planting garden cherry Strong saplings, clear long pruning method can save labor, is conducive to the tree growth, flowering early, high producing strain, cherry cultivation especially suitable for close planting garden. Began to use the long pruning trees, close planting garden big cherry trees should be in 2-3 years old, sparse Park cherry trees should be in strains from 1. 5-2m thick were cut on the pruning method is suitable for the enlarged crown and earlier results of big cherry Strong saplings. Cutting back pruning method for pruning amount is large, is not conducive to large cherry Strong sapling growth, results of late, strains producing low, and Fei Gong, but still apply to slow growth after planting trees or weak trees. Carved bud branch foliage branch number were increased, bouquet spur increase. Long branch flowering rate and lower leaves after topping the flower branch rate increases obviously.
