在>16 m高程的草洲进行不围垦种,采用单纯种植和施用“荣宝”后种植芝麻2种模式,设立不垦种作为对照,1年后观察螺情变化和经济效益。结果显示,垦种1年后单纯垦种组活螺密度下降97.86%,垦种加荣宝组下降100%,对照组下降47.62%。每667 m2产量单纯垦种组15.5 kg,垦种加荣宝组19.5 kg,后者增产25.81%;每667 m2纯收入单纯垦种组56.5元,垦种加荣宝组-36.0元。提示有螺草洲实施不围垦种芝麻具有较好的控螺效果和经济效益。
Two species of seagrass were planted in Caozhou> 16 m elevation. Two models of planting sesame after planting and using “Rongbao” were set up, and no cultivars were set as control. One year later, the changes of spirals and economic benefits were observed. The results showed that after one year of reclamation, the live density decreased 97.86% in the reclamation group, 100% in cultivars plus Rongrongbao group and 47.62% in the control group. Each 667 m2 yield reclamation group 15.5 kg, reclamation and Rongrong group 19.5 kg, the latter yield 25.81%; every 667 m2 net income reclamation group 56.5 yuan, reclamation plus Rongbao group -36.0 yuan. Prompt snails to implement the implementation of non-reclamation sesame species have better snail control effect and economic benefits.
