竹子砍伐后的伐桩俗称竹蒲头。毛竹砍伐后留在林地的竹蒲头,一般要10年左右方会烂掉。据我们调查,一亩毛竹林有10%的林地被竹蒲头所占据,严重影响出笋、成竹。为了加速竹蒲头腐烂及改进竹林施肥方法,我们在竹蒲头内进行了施尿素试验。试验表明,在竹蒲头内施尿素不易流失,也不会被杂草夺走,但竹子能吸收,因此出笋多、产量高;同时,能加速竹蒲头的腐烂,有利于竹林的再生产。在开花竹林中对竹蒲头内灌尿素,还可抑制竹林开花或使开花竹林在2—5年内复壮。所以,在竹蒲头内施化肥是一种值得推 After the deforestation of bamboo cuttings commonly known as bamboo Po head. Bamboo leaves after leaving the bamboo forest in the felling of logging bamboo, usually about 10 years will rot. According to our investigation, 10% of the acre of bamboo forest is occupied by bamboo-pu head, seriously affecting bamboo shoots and bamboo shoots. In order to accelerate the decay of bamboo and to improve the bamboo fertilization method, we conducted a urea application test in bamboo shoots. Experiments show that urea is not easy to be lost in the bamboo shoots, and it will not be taken away by weeds, but bamboo can absorb so many bamboo shoots and high yield; at the same time, can accelerate the decay of bamboo-putrid, is conducive to the reproduction of bamboo . In the flowering bamboo forest on the bamboo shoots head of urea, but also can inhibit the flowering of bamboo or flowering bamboo forest in 2 to 5 years rejuvenation. Therefore, in the Zhupu internal fertilization is a kind of push
