Six Vegetables, namely tomato, cucumber, French bean, radish, Spinach and Chinese cabbage, were irrigated with Petrochemical wastewater containing Phenols and aromatic hydrocarbons and treated with biochemical process. it was found that there were no disadvantageous effects on the growth, Yield and quality of the experimental vegetables. the residues of phenols and aromatic hydrocarbons in edible portions of the vegetable crops as well as in the soil. were indistinct.

利用生化处理石油化工含酚和芳烃混合废水,灌溉了番茄、黄瓜、菜豆、萝卜、菠菜和白菜等6种蔬菜,经过观察,对以上蔬菜的生长、产量和品质均没有不良影响。在蔬菜可食部分和土壤中,酚和芳烃的残留量不明显。而未经生化处理的废水,不仅抑制蔬菜生长、降低产量(菜豆除外),而且使品质变劣,不能食用;在蔬莱可食部分和土壤中,酚和芳烃均有明显的积累。未作处理的废水经4倍稀释后,对黄瓜主根伸长有明显阻碍。所以,引用石油化工废水灌溉蔬菜,必须实行无害化处理(如生化活性污泥法)。

The respiration rate, ethylene production and firmness of the apple fruit (Var.

对国产元帅、红星、新苹、青蕉、小国光等品种苹果采后及贮藏期间果实的呼吸、乙烯产生及硬度等进行了分析测定。结果表明大多数品种采后迅速后熟,呼吸跃变,很快发酥,品质变劣,其间乙烯大量产生,变化最为剧烈。贮藏保鲜效果好的各种处理都抑制或推迟了果实乙烯产生。果实中乙烯的浓度可以作为成熟状态的标示。通过不同时期采收,采后不同时间入库等处理果实生理变化及贮藏效果的比较看出,采后迅速控制后熟进程是提高贮藏质量,延长贮藏时间的关键。来后应用高CO_2,充氮、抽气等预处理对控制后熟有很好的效果。这些结果将为生产上改进贮藏工作,确定适宜采收期,提高贮藏质量等方面提供参考依据。

哈密瓜对新疆农业经济有较大影响。由于病毒病的流行导致大面积减产和品质变劣。WMV-2,CMV和SqMV3种主要病毒的流行和混合感染是病害加重的主要原因。作者在研究各种病毒的理化性质和流行规律的基础上,进行了大面积防治试验,防治措施是:(1)把种子置于70℃恒温箱中持续7—12天左右。(2)在防虫温室中营养钵育苗,增加苗龄后移到田间,以增强植株抗病能力。(3)采用地膜栽培技术,能促进瓜苗生长,增强抗病能力,缩短生长期,使瓜苗在对病毒的敏感阶段避开蚜虫的迁飞高峰,减轻病害。(4)防治蚜虫。采用在田间悬挂银色膜,布置黄色粘性板,喷雾油乳剂及种植屏障作物等,配合使用杀虫农药,能拒蚜虫在瓜田以外消灭,在断绝媒介传播方面效果显著。(5)从革新栽培技术,改进施肥办法,选育抗药品种,提高田间管理水平等多方面入手,大面积示范综合治理病毒的效果。采用上述防治措施后,在5年中近3万亩试验田的结果表明,防病效果在15—90%,增产幅度在18—50%之间。
