Abstract:

The changes of snail situation in the marshlands and the economic benefit of planting were investigated after plan? ning sesame on marshlands above 16 meters’elevation in Poyang Lake at drought period in autumn and by comparing three groups,i.e. planting sesame alone,planting sesame plus fertilizing“Rong Bao” (a brand of one fertilizer),and no planting. Re? sults showed that the yields in the groups of planting sesame alone and planting plus fertilizing were 15.5 kg and 19.5 kg per 667 m2 ,respectively,with the output increasing by 25.81% in the fertilizer group. The net incomes of the two groups of planting sesa? me were 56.5 Yuan and -36.0 Yuan per 667 m2 ,respectively. One year after the planting,the living snail densities of the three groups were decreased by 97.86%,100% and 47.62%,respectively. It is suggested that planting sesame on marshlands with snails in Poyang Lake region has a preferable economic benefit and snail control effect.

摘要:

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。
