摘要
在甘肃省张掖市甘州区三闸镇高寨村三社甜菜种植基地上,采用田间试验方法,进行了糠醛渣生态肥配方筛选及对甜菜经济效益影响的研究。结果表明,糠醛渣生态肥配方比例为:改性糠醛渣0.5114:尿素0.3409:磷酸二铵0.1136:锌钼微肥0.0341。糠醛渣生态肥施用量与甜菜产量间的肥料效应回归方程式为:y=69.43+19.3812x-2.8295 x^2,经济效益最佳施肥量为2.61t/hm^2,甜菜理论产量为100.74 t/hm^2。施用糠醛渣生态肥与传统化肥比较,甜菜单株块根重和块根产量分别增加5.21%和5.26%;施肥利润和肥料投资效率分别增加0.20万元/hm^2和0.51元/元。
The formulation screening of furfural slag ecological fertilizer and effect of the fertilizer on economic benefits of sugarbeet were studied. The results showed that the formula ratio of furfural slag ecological fertilizer was： modified furfural residue 0.5114： urea 0.3409： diammonium phosphate 0.1136： zinc and molybdenum micro element fertilizer 0,0341. The regression equation of application rate of furfural residue ecological fertilizer （x） and root yield of sugar beet （y） was： y=69.43＋19,3812x-2.8295x2. The theoretical root yield of sugar beet was 100.74 t/ha when fertilizer application rate of optimum economic benefits was 2.61 t/ha. In comparison with traditional fertilizer, the root weight and yield of sugarbeet increased by 5.21% and 5.26%; the profit and investment efficiency increased by 2 thousand yuan/ha and 0.51 yuan/yuan, respectively.
