为发展柑桔生产,加速良种繁殖,我场以枳壳为砧木,进行改良橙周年嫁接试验,取得良好结果.实践证明,柑桔一年四季都可以嫁接.情况整理于下:春季嫁接于二至四月进行,用单芽切接与单芽腹接的方法.切接的一般在四月下旬陆续愈合抽芽,抽芽集中,生长势强,到年底株高79公分;干粗1.1公分,分枝3～4条.腹接的抽芽参差不齐,四月下旬检查只发芽22～34%,长势弱,年底株高仅63公分,干粗0.8公分.夏秋季嫁接于五至九月进行,用长片小芽腹接和短片芽接两种方法.这两种方法都适用于夏秋高温季节.愈合快,一般接后9～17天可愈合抽芽,成活率高,抽芽较整齐.五月份接的到年底一般高68公分,干粗0.9公分,分枝3～4条.据观测,五至六月份接的,当年均可出圃.八至九月接的因病虫害严重,气温下降,生长慢,当年来不及出圃.七月接的株高可达48公分,干粗0.6公分,分枝2～3条.八月接的株高只有22.6公分,干粗0.5公分,
In order to develop citrus production and accelerate the breeding of elite seeds, we used Citrus aurantium as rootstock to carry out the grafting experiment of improved orange anniversary and achieved good results. It has been proved that citrus can be grafted all year round. Until April, with a single-bud cut with a single bud Abdominal method.Cut generally follow the end of April heal buds, buds concentrated, growing strong, to the end of the plant height of 79 cm; dry coarse 1.1 cm, Branches 3 to 4. Abdominal buds uneven, check in late April only germination 22 ~ 34%, weak growth, the end of the plant height of only 63 cm, dry coarse 0.8 cm summer and autumn grafting in May to September, With long pieces of small bud sprouting and short film sprouting two methods are suitable for both summer and autumn high-temperature season the two methods of healing fast, generally pick up 9 to 17 days after the bud sprouting, high survival rate, sprouting more neat. To the end of the general high of 68 cm, dry coarse 0.9 cm, branches 3 to 4. According to observation, from May to June to pick up, then the year can be nursery. 八月 to September due to pests and diseases, the temperature dropped, slow growth , Was too late to nursery .In July, the plant height up to 48 cm, dry coarse 0.6 cm, branches 2 to 3. August plant height 22.6 cm, 0.5 cm thick dry,
