在竹伐桩内施化肥,竹子更易吸收,肥料既不会被雨水大量冲走,也不会被杂草吸收。与沟施与围施相比,竹伐桩内施肥具有节省劳力、防止水土流失等优点,同时能加速伐桩腐烂又不伤鞭。利用竹桩伐施碳酸氢铵可以提高出笋率和竹材产量,其肥效与开沟施等氮量尿素基本相同。由于碳酸氢铵肥效低且容易引起竹鞭大量腐烂而不受人们欢迎,而伐桩内施碳酸氢铵可以克服上述缺点。所以,伐桩内施肥不仅为毛竹高产提供了施肥的新方法,而且为滞销的碳酸氢铵开辟了竹区这一新市场。
In the bamboo felling fertilizer, bamboo more easily absorbed, the fertilizer will not be washed away by a large number of rain, weeds will not be absorbed. Compared with the ditch Shi and Wai facilities, bamboo felling within the pile with labor-saving, to prevent soil erosion, etc., at the same time can accelerate the pile rot without injury whip. The use of bamboo bark cutting ammonium bicarbonate can increase the rate of bamboo shoots and bamboo yield, its fertilizer efficiency and ditching facilities such as nitrogen urea is basically the same. Due to the low efficiency of ammonium bicarbonate and easily lead to a large number of decay of whip whites is not welcome, while cutting the internal bicarbonate bicarbonate can overcome the above shortcomings. Therefore, in-pile fertilization not only provides a new fertilization method for bamboo yield, but also opens up a new market for bamboo area for slow-moving ammonium bicarbonate.
