In the autumn and winter season, after bamboo is harvested, chemical fertilizers are poured into fresh cuttings to allow nutrients to enter bamboo whip conveying tissues and then directly used by bamboo to quickly exert their fertilizer efficiency. It must be carried out immediately after the bamboo is cut down. The effect of lateness is not obvious. The newly harvested bamboo plum head is relatively fresh, its physiological function has not been reduced, and its absorption function is strong.
The specific approach is: When cutting bamboo, leave a bamboo section near the ground, use a 2-3 cm thick, very sharp steel needle, the bamboo pile inside the compartment to open up, into the fertilizer, and then sealed with mud Cover, the amount of fertilizer depends on the type of bamboo, the density of bamboo posts and the type of fertilizer. If urea is applied, apply 5-8 kilograms per acre and apply 0.05-0.1 kilograms per bamboo pile; if applying ammonium bicarbonate, apply 8-10 kilograms per acre and apply 0.1-0.2 kilograms per bamboo pile. This type of fertilization is not limited by terrain. Flat land, slopes, deserted bamboo forests, bamboo forests, and small pieces of bamboo forests can be applied.
