摘要
在地形复杂、坡度较陡、大雨频繁的毛竹林区,采用免耕施肥技术,既不造成水土流失,又能达到增产的效果。经试验,每年施碳铵70～80kg/亩、尿素15kg/亩的试验区比对照区竹笋增产69.88％,竹材增产34.94％,毛料增产30.93％;每年施碳铵40kg/亩和尿素20kg/亩的示范区比示范前竹笋增产669.2％,竹材增产131.82％,毛料增产97.54％。本研究免耕施肥方法有:开水平沟、竹蒲头打洞和每竹眉形沟施三种,均有明显效果,但三种方法之间无显著差异。
In some major bamboo areas with varied topography and steeper slops. Using the method of fertilizing without plough will not only avoids soil erosion from tempest, but also rais the output. The test results show: for applying (NH_4)_2HCO_3 70～80 kg/mu, urea 10 kg/mu every year, the output of bamboo shoots, timbers and branches in test areas are respectively increased 69.88%, 34.94%, and 30.93% in comparison with the contrast areas. For applying (NH_4)_2HCO_3 40 kg/mu and urea 20 kg/mu every year, the output of bamboo shoots, timbers and branches after testing in the model areas are respectively increased 669.2%, 131.82% and 97.54% in comparison with the before testing. In this test the ways of fertilizing with digging line ditches, breaking hole beside bamboo stocks and digging curve ditches have all got significant efficiency but there are no significant difference among these ways.
