摘要:

采用稻田围隔法,系统地研究了一次性施肥技术中不同有机和无机氮肥比例施用量在稻田养蟹条件下对河蟹(中华绒螯蟹)的生长状况、营养状况及产量的影响。结果表明:与传统施肥方式(FP)和测土推荐施肥方式(OPT)相比,A1配方施肥对河蟹的生长及产量、品质均有较好的效果,河蟹收获时蟹肉可食部分中蛋白质、脂肪、水分含量分别为20.3%、6.3%和72.0%;同时水稻产量也较高,达到10530.5kg/hm2,A1处理的成活率也较高,为 66.7%,能够满足实际生产的需要。而OPT处理只对水稻产量反应较好,对河蟹生长有一定的影响。

Abstract:

The effect of different ratio of organic and inorganic nitrogen fertilizers on the growth, nutrition, as well as yield of crabs was investigated when these fertilizers was applied for once under a symbiosis system composed of paddy and crab. Comparing to conventional famer practice (FP) and optimum fertilization (OPT), treatment A1 (balanced fertilization) had a satisfied result on the growth, as well as the yield and quality of crab. The contents of protein, fat and moisture in edible part of crabs were 20.3%, 6.3% and 72.0% respectively. At the same time, the yield of paddy was the highest with number of 11002.5kg/hm2. The survival rate of crabs was as high as 66.7%, which could satisfy the demand of agricultural production.As far as OPT treatment was concerned, it seemed more suitable for paddy instead of crabs.
