“发枝素”是用于果树上的化学整形生物药剂。它能促使果树芽体发枝,减少光秃部位,增加短枝量,提早结果。“发枝素”是一种粘稠膏体药物,被涂抹的芽一般5—7天即萌出新芽抽枝。从萌芽抽枝到新枝健壮生长的全过程仅涂抹一次即可,且涂药后不怕风吹日晒和喷药、淋雨。根据几年来试验,应用“发枝素”整形,对果树的芽体、枝条、树体没有发现任何不良作用。据北农大解剖观察,涂抹本品两天后芽体膨大,6天时鳞片裂开,皱梢间伸长,并可见侧芽原茎。14天侧芽次生木质部明显增厚,20天侧芽的解剖结构已和主茎一样。据在万亩果树中试验推广应用证实,它对果树定位发枝,减少光秃部位,增加短枝量,均有明显效果,对不同的苹果树新梢侧芽萌发率可提高2—5倍,涂抹1—3年生枝侧芽、叶丛枝芽和隐芽, “Hair Dye” is a chemical plastic biologic agent used on fruit trees. It can promote fruit bud body branches, reduce the bare area, increase the amount of short branches, early results. “Hair branch element” is a thick paste medicine, the bud is smeared 5-7 days that sprouting sprouting shoots. Sprout shoots to the new branch robust growth of the whole process can be applied only once, and after the application of wind and sun are not afraid of spraying, rain. According to several years of experiments, the application of “hair root element” plastic, fruit buds, branches, trees did not find any adverse effects. According to Peking University anatomical observation, smear the product after two days bud bulge, 6 days when scales flake, folds between the elongation, and visible bud side of the original stem. On the 14th day, the secondary xylem was obviously thickened, and the anatomy of the lateral bud on the 20th day had the same level as the main stem. According to the experiment and popularization and application in 10,000 mu of fruit trees, it confirms that it has obvious effect on locating and setting branches of fruit trees, reducing bare areas and increasing the amount of short shoots. The germination rate of shoots of different shoots of apple trees can be increased by 2-5 times, Apply 1-3 years old branches lateral buds, leaf buds and buds buds,
