The development of precision agriculture has higher and higher request for the intelligence of agricultural equipment.Especially in precisely variable rate fertilization, a key operation link of precision agriculture is able to precisely conduct variable rate fertilization,according to fertilizer requirement of crop, which makes the yield maximized in prior to reducing the total amount of fertilizer.The paper summarizes scholars research findings at home and abroad in variable rate fertilization, including control modes of variable rate fertilization, the realization way of fertilization link and the executive mechanism of variable rate fertilization.The main control modes have single chip microcomputer control, CAN bus control, PID control algorithm,the spectra of real time monitoring and control and so on.On the basis of concluding previous research achievements and experience, the paper summarizes the characteristics of the current development of domestic variable rate fertilization, proposing present problems.

烟草病毒病俗称烟草花叶病,这是目前烟草生产上分布最广、发生最为普遍的一大类病害,以烟草黄瓜花叶病毒(CMV)、烟草普通花叶病毒(TMV)引发的病毒病在生产上比较普遍.烟草普通花叶病自苗床期至大田成株期均可发生,苗期的初侵染源主要是土杂肥带毒、种子中混杂病残体、风及人为操作、带病的其他寄主,幼苗发病后,通过摩擦使叶片产生微小伤口引起再侵染,主要发生在苗床期至大田现蕾期.黄瓜花叶病毒主要在越冬蔬菜、多
使用除草剂是稻田杂草防除的主要措施,稻田除草剂使用面积已占水稻种植面积的90％以上,除草剂用量达2万t(按有效成分)左右,占除草剂作物市场份额的24％左右.但是,由于除草剂长期单一使用、滥用现象比较普遍,导致稻田杂草抗药性问题越来越突出,兑水稻生产安全、农业生态安全造成严重威胁.为了解稻田杂草抗药性发生和危害现状,促进稻田杂草科学有效治理,2015年6月23～28日,我们对安徽、江西、湖南等省8个
虉草(Phalaris arundinacea L.)为禾本科虉草属(Phalaris SP.)草本植物,在农业生产上主要危害麦类(大、小麦)、蚕豆、油菜等旱地作物.近年来,楚雄地区小春旱作田间虉草危害严重,在楚雄地区有两个种,分别是小子虉草(小虉草)(Phalaris minor Retz.)和奇异虉草(奇虉草)(Phalaris paradoxa L.).为抓好麦类作物田虉草防除工作，促进农民
芦笋在生产过程中常遭受鼠类危害,害鼠不但啃咬芦笋肉质根、地上茎、地下茎等器官,而且传播细菌、病毒及寄生虫等疾病,对芦笋产量及品质造成极大影响.漯河市亿康工贸有限公司作为一家拥有自营进出口权的农副产品深加工企业,为确保芦笋生产达到HACCP、欧盟IFS等国际质量体系认证要求,于2015年5月在漯河市郾城区龙城镇芦笋种植基地进行了0.005％溴鼠灵毒饵毒杀农田害鼠的药效试验.试验结果表明，0.005%
