【目的】对广西甘蔗研究所研制的30%N-B多元素甘蔗专用杀虫复合肥进行对比试验,研究其对甘蔗生长的影响,筛选出既能促进甘蔗生长又能有效防治甘蔗螟虫的多功能复合肥。【方法】按氮、磷、钾三要素相等设4个处理,分别是A“:丰岭牌”30%N-B多元素甘蔗专用杀虫复合肥单施;B“:丰岭牌”25%N-B多元素甘蔗专用复合肥加施呋喃丹;C“:丰岭牌”25%N-B多元素甘蔗专用复合肥单施;D:尿素、钙镁磷肥、硫酸钾配施。在甘蔗生长过程调查出苗率、分蘖率、生长速度、虫害情况;收获期调查株高、茎径、有效茎数,分析甘蔗品质,并验收产量。【结果】处理A出苗率较高,其次为处理B,处理C、D出苗率较低。分蘖率方面,处理A前期较多,后期较少;而处理C、D则是前期较少,后期较多。与其他处理相比,处理A在9月前及10、11月株高长速均较快。处理A实收产量71565kg/ha,比处理B、C、D分别增产8595、11700和11835kg/ha。处理A、B对螟虫具有良好的防治效果,其中处理A的效果优于处理B。4个处理对甘蔗品质的影响差异不大。处理A农业效益达6756.45元/ha,比处理B、C、D分别增加2661.30、2949.00和2885.55元/ha,工业效益达13883.55元/ha,比处理B、C、D分别增加1478.7、1839.00和2805.45元/ha。【结论】30%N-B多元素甘蔗专用杀虫复合肥能有效控制甘蔗螟虫的危害,且可促进甘蔗早分蘖,提高成茎率,增加有效茎,促进蔗株伸长,增加单茎重,从而显著增加甘蔗产量,提高其经济效益。 【Objective】 The objective of this experiment was to compare the effects of 30% NB multi-element sugarcane special insecticidal compound fertilizer developed by Guangxi Sugarcane Research Institute on the growth of sugarcane and to screen out the multi-functional compound which can promote the growth of sugarcane and effectively control sugarcane borer fat. 【Method】 According to the three elements of nitrogen, phosphorus and potassium, the four treatments were equal, which were A “: Fengling brand ” 30% NB multi-element sugar cane special insecticide compound fertilizer, “25% NB multi-element sugarcane special compound fertilizer Shi Fu carbofuran; C ”: Fengling brand "25% NB multi-element sugarcane special compound fertilizer single application; D: urea, calcium magnesium phosphate, potassium sulfate with. During the growth of sugarcane, the emergence rate, tillering rate, growth rate and insect pests were investigated. The plant height, stem diameter and number of effective stalks were investigated during the harvesting period to analyze the quality of sugarcane and to check the yield. 【Result】 The emergence rate of treatment A was higher, followed by treatment B, and the treatment C and D had lower emergence rate. In terms of tillering rate, there were more pre-treatment A and less post-treatment A, while C and D were less pre-treatment and more post-treatment. Compared with other treatments, treatment A had faster plant height in September and October and November. The actual yield of treatment A was 71565kg / ha, which increased 8595, 11700 and 11835kg / ha respectively than that of treatments B, C and D. Treatment A, B had a good control effect on stem borers, of which treatment A was better than treatment B. The effects of 4 treatments on the quality of sugarcane were not significant. The agricultural benefit of treatment A reached 6756.45 yuan / ha, which was 2661.30,2949.00 and 2885.55 yuan / ha higher than that of treatment B, C and D, respectively. The industrial benefit reached 13883.55 yuan / ha, which was 1478.7,1839.00 and 2805.45 more than that of treatments B, C and D Yuan / ha. 【Conclusion】 The 30% NB multi-element sugar cane special insecticide compound fertilizer can effectively control the damage of sugar cane stem borer, and can promote the early tillering of sugarcane, increase the yield of stem, increase the effective stem, promote the elongation of cane and increase the weight of single stem Significantly increase the output of sugarcane and improve its economic benefits.
