Application of Secondary Nutrient Fertilizer Produced by Leili Group in Rice in Lichuan City

On basis of tests in regions with different elevations, rice sprayed with secondary nutrient fertilizers （×1 000） produced by Beijing Leili Group would signifi-cantly increase yield and incomes, which can be widely applied in Lichuan City or similar areas. With the fertilizer applied, rice yield can be improved by 292.5-505.5 kg/hm2, with increase of 6.63%-10.92%; farmer’s incomes can be enhanced by 877.5-1 516.5 yuan/hm2, with net income growth of 783-1 422 yuan; output-to-input rate kept in 8.29-15.05. The increased rice yield is mainly contributed by the in-creases of setting percentage and thousand-seed weight, of which the former＇s role is more significant. Hence, the fertilizer can be widely applied in Lichuan and similar regions.

雷力海洋性肥料在马铃薯化肥和农药减施模式中的应用效果研究

本文研究了雷力海藻有机颗粒肥和雷力海洋寡糖(褐藻双寡糖和壳寡糖)在马铃薯化肥农药减施种植模式中的应用效果。结果表明,化肥农药减施+雷力海洋性肥料处理马铃薯植株生长茂盛、茎较粗、叶片深绿、大薯率高、产量高。其中:青海示范区(湟中县)化肥农药减施+雷力海洋性肥料处理马铃薯产量、大薯率分别为77727.27 kg/hm2、74.9%,较化肥对照增产18.75%;青海示范区(互助县)化肥农药减施+雷力海洋性肥料处理马铃薯产量为41111.1 kg/hm2,较化肥对照增产18.40%。说明雷力海藻有机颗粒肥和雷力海洋寡糖在马铃薯化肥农药减施模式中应用效果较好,可以推广应用。

雷力海洋性肥料在青海省马铃薯零化肥和零农药种植模式中的应用

本文研究了海藻有机颗粒肥、褐藻双寡糖和壳寡糖等海洋性肥料在青海省马铃薯零化肥和零农药施用种植模式中的应用。结果表明,与空白对照相比,马铃薯产量、大薯率和增产率均为最高,分别为52045.45 kg/hm^2、85.76%和59.47%;与常规化肥对比,马铃薯产量减少6.38%,而大薯率提高8.9个百分点,VC、淀粉和蛋白质含量分别增加11.22%、14.72%和10.89%。该技术的应用符合农业部制定的“化肥零增长”“农药零增长”和青海省打造一批绿色产品基地、有机产品基地、知名品牌基地,提高农产品质量,增加绿色、有机农产品供给,提高国内外市场竞争力的战略定位,也能为三江源、“中华水塔”的青海省绿色生态建设作出重要贡献。
