大棚养殖蚂蚱 闯出发财新路

近日,笔者来到河北省徐水县留村乡南庄村,走进师大力家的蚂蚱养殖大棚.大棚支架由竹竿做成,四周用纱网罩起来,每个大棚面积都达100平方米.钻过投料口走进棚内,只见地上密密麻麻地落满了蚂蚱,让人不敢落脚.见到有人靠近,蚂蚱立即"惊慌失措"地蹦到大棚的另一头.正在给蚂蚱喂草的师大力介绍说,他家养的蚂蚱是"东亚飞蝗",其营养成分含量高,个头大,无污染,是餐桌上备受消费者青睐的"绿色食品".蚂蚱养殖投资小、见效快、方法简单,非常适合家庭经营.     

Study on Cultural Technologies and Salt-resistance of Nitraria sibirica in Coastal Areas with Serious Salt-affected Soil

In this research, five Nitraria sibirica provenances such as Dayilu were selected to do experiment of salt-resistance, combining fixed plots test with typical plot investigation, measuring survival rate and growth as main indicators. The experiments of main cultural technology were done on Nitraria sibirica in 4 types of site preparation, 3 types of planting, 3 designs for planting density. The Nitraria sibirica experiments for the effects of curbing salt and improving soil were done by testing soil nutrients, salt content, soil physical properties as focal points in typical site of 3-4 years woods. The experiment results showed that the Nitraria sibirica could survive well with soil salt content of 0.6%, and that survival rate declined distinctively as soil salt content exceeded 0.8%. However, high soil salt content did not influence growth in the year of planting. There were obvious differences in salt-tolerance among Nitraria sibirica provenances; Dayilu was the best on salt-tolerance, the other 4 pro     

内陆大水域的“高效、环保”施肥养鱼技术——科洋水产专用大水面专用肥

由于水库、湖泊等内陆水域水面广、容量大,不仅发挥着重要的蓄水、灌溉功能,而且具有广阔的渔业利用前景。近年来,为了改变粗放粗养模式下大水域养殖产量偏低、效益不高的现状,许多养殖单位和渔农在水库、湖泊等大水域中进行了施肥养鱼的有益尝试。生产实践证明,化肥养鱼成本低
