龙源光合生态液在水稻上的应用效果

光合细菌是一种古老的有益微生物 ,施入土壤中进一步生长、繁殖 ,能固氮、同化二氧化碳、分解有机物、提高土壤肥力、减少病害发生和促进作物生长。龙源光合生态液是盘锦龙源生物技术应用研究所用光合细菌制成的一种液体生物肥 ,１ｍｌ含光合细菌２０亿。本文用田间对比试验方法 ,初步探索了该产品在水稻上的应用效果 ,供读者参考。一、试验内容与方法１.试验内容试验地选择在盘山县坝墙子镇李英辉稻田 ,土壤类型为盐渍型水稻土 ,肥力均匀 ,排灌条件较好。试区面积０．３ｈｍ２ ,分作两块 ,每块０．１５ｈｍ２,一块作水稻施光合生态液试验田…     

球痢清等药物对人工感染兔肠球虫病的治疗比较试验

４８只３０日龄大耳白杂种兔，试验接种感染兔肠球虫的５种混合孢子化卵囊，将球痢清Ｉ、球痢清Ⅱ、莫能霉素和氯苯胍分别拌在饲料中饲喂，以比较其抗兔肠球虫的效果。通过临床观察，分析克粪便卵囊数的变化，记录增重、计算饲料转化率和对每组扑杀兔作病理组织学检查，结果表明：球痢清抑制卵囊产生、减轻肠道病变、增重及饲料转化率的效果明显，与莫能霉素相近，并显著优于氯苯胍。氯苯胍效果较差，几乎与接种不给药组相同。无显著性差异。因此说明氯苯胍不宜单一继续使用。应引入新的高效抗球虫药，并指导正确使用抗球虫药物。     

新炎瘟清片对人工感染鸡巴氏杆菌病的临床疗效试验

用新炎瘟清片以高(2片／kg.b．w)、中(1片／kg．b．w)、低(0．5片／kg.b．w)三个剂量对人工感染鸡巴氏杆菌病的鸡群口服治疗，同时设立盐酸环丙沙星对照组。试验结果表明：用药2d后，新炎瘟清片高、中剂量组的有效率分别为93．3％、93．3％，效果优于对照药物盐酸环丙沙星对照组(70．0％)。     

有机栽培水肥一体化系统设计与试验

A water and fertilizer integrated system for organic cultivation was designed. The system integrated functions of preparing and compounding organic liquid as well as automatical irrigation. Through different subroutines of the system, the aerobic fermentation of organic materials, liquid filtration, compounding and dilution of stock solution, and decision and execution of irrigation strategy can be conducted. Thus, the integration of preparation and management of nutrient solution in organic cultivation, as well as high efficiency and fine management in water and fertilizer could be achieved. In order to verify the reliability and applicability of the system, coconut chaff was selected as organic matrix and non soil and organic cultivation experiment of cucumber was carried out in the solar greenhouse. The results showed that the system was operated stably in preparation of organic liquid and management of water and fertilizer was good in cucumber cultivation. The mechanization and automation of organic fertilizer and water management was implemented. The yield of cucumber was up to 48165kg/hm2, the content of total soluble sugar, vitamin C and titratable acidity were 2.7%, 99.2mg/kg and 008%, respectively. The development and application of this system would break through the bottleneck that existed in water and fertilizer management in organic cultivation, and it had important realistic significances.     

自动清粪机器人路径规划方法的研究与实现

自动清粪机器人的工作环境复杂,不仅有静态障碍物(如牛栏),且动态障碍物众多(如人和牲畜等)。为此,提出了一种基于行为方法的路径规划法。该方法非常适合于动态环境下机器人的运动规划,其原理简单、计算快捷、容易实现。根据该算法,确立了一套完整的软件系统和设计方案,并在此基础上制造出了样机。经过样机在奶牛养殖场的工作和测试,验证了该方法的实时性、准确性和可操作性。     

规模化猪场的粪便处理与利用

猪场的环境污染已成为影响养猪业可持续发展的主要影响因素,猪场采取适当方式清理粪污,并对其实行一定处理,加以循环利用,将有效减少猪场对环境的污染,并且产生可观经济效益。     

池塘中蓝藻快速清除法

养殖池塘中蓝藻的大量繁殖，对水体和水产品种造成了较大的危害：一是蓝藻的大量繁殖，抑制了鱼虾类及其他浮游生物的正常生长繁育；二是蓝藻覆盖水面，使池塘中的溶解氧降低，
