以进口高浓度速效复合肥单独施用为对照,在果蔗上进行缓释肥施肥方法试验。试验结果:(1)缓释肥单独施用或与进口复合肥相结合施用,其施肥次数为4次,进口复合肥单独施用9次;(2)各处理的出苗率、茎径、有效茎等性状差异不大,但株高存在差异,最高的是CK,达294.6cm,与其他3个处理差异均达极显著水平;(3)蔗茎产量最高的为CK,达159.81t/hm2,T3与其无显著差异,T1、T2与其差异分别达极显著和显著水平;(4)生产成本最高的是CK,达68 812.5元/hm2,与其他3个处理差异均达极显著水平;(5)T3处理的生产效益最高,达12.488万元/hm2,比对照增加收入4 992.0元/hm2;其次为T2处理;T1处理的最低。因此,在果蔗生产中应用缓释肥,不仅可减少施用次数,降低生产成本,还可提高单位面积纯收入,是果蔗省工增产增收的有效措施。
In order to control the application of high-concentration fast-acting compound fertilizer separately, the method of slow-release fertilizer application on sugarcane was carried out. The results were as follows: (1) The slow-release fertilizer was applied alone or in combination with imported compound fertilizer, the number of times of applying fertilizer was 4 times and that of imported compound fertilizer alone was 9 times; (2) The emergence rate, stem diameter and effective stem There was no significant difference in traits, but there were differences in plant height. The highest CK was 294.6 cm, which was significantly different from the other three treatments. (3) CK with the highest cane yield was 159.81 t / hm2 and T3 (4) The highest production cost was CK, reaching 68 812.5 yuan / hm2, which was significantly different from the other three treatments. (5) The production benefit of T3 treatment was the highest, reaching 124.888 yuan / hm2, which increased income by 4 992.0 yuan / hm2 compared with the control, followed by T2 treatment and T1 treatment lowest. Therefore, the application of slow-release fertilizer in the production of cane can not only reduce the number of applications, reduce the production cost, but also increase the net income per unit area, which is an effective measure to increase output and increase income of sugar cane.
