一、增强插梢“根原体”和“薄壁细胞”的活力。我在实践中发现:插后,难生根、少生根、不发芽的插梢是多年的老化枝梢、株冠内部过分密聚的纤细枝梢,或受菌虫害污染过的枝梢。那些生根快、根多而粗,发芽早而壮实,开花快的插梢是当年萌发而成的接近成熟的壮实圆滑、无污染的春梢。这是因为当年发育接近成熟的春梢,生命力特别旺盛,所积累的有机物质,尚未因发新芽而被消耗。叶节间的枝皮充满着“根原体”,皮层里的薄壁细胞活力强盛,分生组 First, to enhance the shoot tip “root” and “parenchyma” vitality. I found in practice: after insertion, difficult to root, less rooting, not budding pinch is the aging of many years of branches, crowns too crowded branches inside the crown, or by the pests and diseases polluted branches. Those rooting fast, more and more roots, germination early and sturdy, quick-flowering plug is the germination of the year approaching mature strong smooth, pollution-free spring shoots. This is because the development of spring shoots close to maturity, vitality is particularly strong, the accumulation of organic matter has not yet been consumed due to hair sprouting. Leafy branches between the branches filled with “root”, the cortex cells in the potent, meristematic group
