新平县中海拔地区玉米品种筛选试验

为了筛选出适合当地的玉米品种,2016年5—10月,在云南省新平县漠沙镇胜利村开展了8个玉米品种的比较试验。结果初步表明,胜玉10号667 m^2产量达663.4 kg,比对照宣黄单5号增产达极显著水平,且抗逆性表现较好,可以在该地区大面积推广应用;靖单12、北玉0913、安特8000、云瑞89、雅玉78在该地区使用,应当使穗期错过雨量较多的月份;雅玉891茎腐病和穗腐病发病率高,不适合在该地区种植。

新平县晚稻优化配方施肥试验初报

为摸清土壤养分校正系数、土壤供肥能力、养分吸收量和肥料利用率等基本参数,给指导晚稻生产施肥提供科学依据,2017年在云南省新平县漠沙镇安排实施了"3414"部分试验。结果表明:该试验田肥力中等,富含P肥、K肥,N肥对产量的影响力最大,肥料三要素对产量的影响力依次为N>K>P;N_2P_2K_2处理(即667 m^2施用N 14.0 kg、P_2O_5 7.0 kg、K_2O 5.6 kg)可作为当地晚稻最适合的配方应用。

探究猪水肿病的诊疗与防控措施

作为生猪养殖中的常见细菌性疾病,猪水肿病一直以发病急切、过程迅速、致死率高著称,常出现在断奶1~2周的仔猪群体中。其中又以体格健壮、长势较快、膘情较好的仔猪最为多发,病猪一旦发病,病情在短期内便会加速恶化,如果没有尽快采取相应的诊疗与防控措施大概率会死亡。因而,对于该病,必须做到尽早诊断、尽快治疗,并施以一系列针对性的防控措施,致力于诊疗与防控的同步进行,方能将危害降至最小,笔者主要就各相关要点加以探究。

猪坏死杆菌病的类型与防控措施

坏死杆菌病是生猪较为高发的一类细菌性疾病,主要由坏死杆菌所引发,不仅具有较高的致死率,而且会对生猪生长发育造成严重抑制。该文分析了猪坏死杆菌病的常见类型,探讨了猪坏死杆菌病的防控措施,以期为广大生猪养殖人员提供参考。

Selection Experiment of Varieties of Maize in Ailao Mountainous Areas

[Objective] This study aimed to select suitable varieties of maize for Ailao mountainous areas, [Method] A comparison test of eight varieties of maize was conducted in Shengli Village, Mosha Town, Xinping County, Yunnan Province from May to October in 2016. [Result] The yield of Shenyu 10 was up to 66.3.4 kg/ 667 m^2 and there were extremely significant differences between Shenyu 10 and Xuanhuangdan 5 （CK）. Moreover, it had strong stress resistance. As Jingdan 12, Beiju 0913, Ante 8000, Yunrui 89 and Yayu 78 were planted in the region, their earing should not appear in rainy months. The inciderce of stem rot and ear rot of Yayu 891 was high, so Yayu 891 should not be planted in the region. [Conclusion] Shenyu 10 had a high yield, suffered few diseases and had strong stress resistance, so it can be popularized widely in the region.
