一、高接更换品种 在春秋两季及5～6月高接优良的柑桔良种进行换代。 二、尽量疏剪长放 逐年疏删部分直立枝组和强旺侧枝,促使留树枝梢多次分枝。 三、断根控水 秋季将旺长强树挖开树冠滴水处土层,切断1～2厘米的大根和侧根,削平伤口后施肥覆土;或在秋冬干旱期将冠下表层根系挖出“晾根”,待叶片微卷后施肥覆土,造成植株暂时生理干旱以促花。春季枝梢萌发期将主根下部20厘米土壤掏空,沿主根周围刻伤韧皮部,削弱根系生长,以减弱树冠旺长促花。 四、拉枝压势 采用绳索
First, the high access to change the varieties in the spring and autumn in two seasons and 5 to 6 months followed by good citrus seed replacement. Second, try to sparse long-term sparsely year by year by deleting part of the upright branches and strong side branches, prompting to stay branches repeatedly branching. Third, cut off the root water control Wang Changqiang tree dug canopy drip soil at the fall, cut off 1 to 2 cm of large roots and lateral roots, flatten the wound after fertilization soil cover; or in the autumn and winter drought under the crown of the surface root dug “root ”, Until the leaves after the micro-volume fertilization soil cover, resulting in temporary physiological drought in plants to promote flowers. During the germination of spring shoots, 20 cm of soil beneath the main roots are hollowed out and the phloem is carved around the main roots to weaken the root growth and weaken the canopy growth. Fourth, pulling pressure with rope
