池塘颗粒饲料驯化养鱼试验报告

1987年以来,我省从北京引进颗粒饲料驯化养鱼技术后,相继在哈尔滨、密山、绥化、肇东等市、县逐步推广。实践证明,采用颗粒饲料驯化养鱼,比传统养鱼方法在产量和效益上都有很大的提高,是一项受养鱼群众欢迎的先进适用断技术。为了大面积推广和应用这项新技术,1992年,我们对绥化市太平川镇西太平村的390亩池塘进行了颗粒饲料驯化养鱼试验。经过一年的实践,390亩池塘共产鱼13.3万kg,其中商品鱼8.85万kg,鱼种4.45万kg,

土壤处理对西洋参根际线虫数量动态的影响及对防治茎线虫根腐病的效果

 Root rot of American ginseng (Panax quinquefolium) caused by Ditylenchus destructor is a novel disease found recently in Beijing area. The effects of three soil treatments (fumigating with chloropicrin, chloropicrin + lvfeng organic manure and nematicide fosthiazate) on the number of rhizospheric nematodes, survived plants, root yield and root rot of 3-year ginseng plant were compared. The effects were also investigated at the second year after treatment. The results indicated that the number of parasitic nematodes in rhizosphere of treated soil reached the peak value in late June to early July as the soil temperature raised in the growing season. Compared with the regular treatment, the number of plant parasitic nematodes was reduced while non-plant parasitic nematodes increased. The number of non-plant parasitic nematodes in the soil treated with chloropicrin + lvfeng organic manure was 2 times than that treated with chloropicrin only. The ratio of non-parasitic to parasitic nematodes of three treatments was higher than the control. Percent of survived plants was 94.8%-96.4% and diseased root was decreased obviously. The control efficacy was more than 89% at the first year after treatment. The survived plants and plot yield of ginseng increased significantly and the control efficacy was around 40% at the second year. The best of the three treatments was by chloropicrin + organic manure.     

保护性耕作条件下河北粮食作物植物保护新问题和治理对策

保护性耕作是相对于传统翻耕的一种新型耕作技术,已在我国北方大面积推广应用。近年来随着新的耕作方式的实施我国河北省小麦全蚀病等土传性病害发生程度加重,发生范围扩大;小麦赤霉病等南方性病害向河北蔓延;农田草害加重;次要病虫害上升为主要病虫害等。本文对保护性耕作条件下,粮食作物上出现的新的植物保护问题进行了综述,并对治理对策进行了探讨。     

2010年黑龙江省渔业防灾减灾对策

一、2009年自然灾害对渔业生产的影响 2009年气温总体接近常年，生长季热量前期较高，秋季气温正常略低。全年降水总量正常，局部地区特别是秋季降水略多于往年。全年气候仍呈春季低温少雨的特点，对春放春养管理有一定的影响。气温总体接近历年平均水平，生长前期和后期热量不足。水总量虽较正常略多，但分布不够均衡。
