In the dry nursery bed,water nursery bed,dry planting field and water planting fieldtrials,pre-sowing applications of sodium PCP at 5 to 20 kg.per ha.did not give good controlof barnyardgrass(Echinochola crusgalli(L.)Beaur.).In the transplanting field trials,pre-transplanting treated with sodium PCP at the rates of15 to 30 kg.per ha.gave a control from good to excellent of barnyardgrass and Cyperusglobosus All..A rate of 30 kg.per ha.applied at one day before the seedlings were trans-planted was most effective,it gave 92.7% control of barnyardgrass and 79.6% control ofCyperus globosus All.Post-transplanting treated with sodium PCP at 15 kg.per ha.5 daysafter puddling also gave good control of both weeds.With different formulations of sodiumPCP tested(granular,soil-mixed and solution)post-transplant-applications of granular or soilmixed gave better control of barnyardgrass,but a solution was proved to be more effective forthe control of Cyperus globosus All.than the other two farmulations.No treatment caused rice injury.Yields of rice on all plots treated with sodium PCPwere higher than the unweeded plots,but were less than twice hand weeded plots.Unsatisfation for the control of barnyardgrass in the nursery beds and planting fieldswith sodium PCP was discussed.

在旱秧田、水秧田、旱直播田和水直播田的试验中,播前施用五氯酚钠,每公顷5—20公斤,除草效果不够良好。但在插秧本田的试验中,插前每公顷施用五氯酚钠15—30公厅对防除稗草(Echinochloa crusgalli (L.) Beauv.)和球穗莎草(Cyperus globosus All.)的效果极为良好。以在插秧前一天,每公顷施用30公斤效果最好,对稗草和球穗莎草的防除效果分别达到92.7%和79.6%。插后处理,每公顷施用五氯酚钠15公斤,效果也较好。另外的试验,观察了五氯酚钠不同剂型:颗粒剂、混土、溶液等的防除效果。防除稗草用颗粒剂和混土处理要优于溶液处理;防除球穗莎草则以溶液处理为最好。各处理对水稻均无药害,所有用五氧酚钠处理区的产量均高于不除草区,但较两次人工除草的为低。本文讨论了在秧田和直播田用五氯酚钠防除稗草效果较差的原因。

试验所用柞蚕品种为青六号,以蒙古栎为饲料,二眠前在室内饲养,其后则在山上放养。所用微量元素为锰、锌、铜、钴及硼,浓度均为千分之一克分子溶液,室内饲养时,溶液涂抹于叶的两面,放养时则喷洒在树叶上。 试验结果表明:在初期生长上,孵化后270小时,添饲微量元素的各组,百蚕体重均超过对照,其中硫酸锌组、氯化钴组及硫酸铜组分别超过对照9.96%、9.39%及7.91%。在发育上,孵化后101小时起青蚕数,除硫酸铜及氯化钴两组外,其他各组均多于对照组。另外,茧的大小,茧重及茧层率等,除硼酸组外,各组均超过对照,亦证明添饲微量元素对柞蚕后期生长发育有良好作用。在抗病力上,对脓病没有什么效果,其中硼酸反而有不良作用,但对软化病的抗病力有显著增加,其中硫酸锰组,硫酸铜组,氯化钴组及硫酸锌组的发病率分别低于对照组22.32%、21.81%、19.65%及18.86%。

本文介绍1960年在广西新发现的两种蔗龟及其生活习性的研究结果。其中一种我国除台湾外,南方蔗区未见报导。我们在百色专区调查,确定它们是寡食性,即兼食玉米,高梁及其他禾本科作物,但嗜好甘蔗。通常在4—5月雨后,是成虫由蛹室出来的最盛期。主要以成虫为害,取食蔗苗茎基部,随着附近玉米和高粱幼苗的生长,部分成虫迁移到这些作物田内。迁移原因颇多,但具有意义的是与田间微气候和食料质量有关。蔗龟的数量及其为害面积,在不同年份是不一致的,大量繁殖的年份和消沉的年份,常表现出不规则的交替现象。此种数量变动,视许多生态因子而定,特别是受4—5月份降雨量的支配。
