本文是关于四种肥料用于毛竹幼林生长试验的报导。该试验进行了三年,试验结果证明施肥区的竹子产量与不施肥区相比明显增加。四种肥料对于新竹鲜重的影响次序为:菜饼(每亩454.27公斤)>二氧化硅(每亩301.13公斤)>尿素(每亩272.01公斤)>磷酸二氢钾(每亩227.28公斤),显然,菜饼和二氧化硅优于其他两种肥料。上述四种肥料每亩的最佳配方是,菜饼150公斤,二氧化硅1公斤,尿素12.5公斤,磷酸二氢钾2.5公斤。使用这个配方毛竹产量会逐年增加,其中以第三年增加最为迅速。
This article is about four kinds of fertilizers used in young bamboo forest growth test reports. The experiment was conducted for three years and the results of the experiment showed that the bamboo yield in the fertilization area was significantly increased compared with that in the non-fertilization area. The order of influence of four kinds of fertilizers on the fresh weight of Hsinchu was: vegetable cake (454.27 kilograms per mu)> silica (301.13 kilograms per acre)> urea (272.01 kilograms per acre)> potassium dihydrogen phosphate (227.28 kilograms per acre) Obviously, pie and silica are better than the other two fertilizers. The best recipe for the above four kinds of fertilizers per mu is: 150 kg of cake, 1 kg of silica, 12.5 kg of urea and 2.5 kg of potassium dihydrogen phosphate. With this formula bamboo yield will increase year by year, of which the fastest increase in the third year.
