土肥管理和微生物菌剂对向日葵菌核病的防治效果及产量的影响

为了研究土肥管理和微生物菌剂对向日葵菌核病的防治效果及产量的影响,通过不同的土肥管理及在3个关键时期采用生防菌进行预防,在成熟期对向日葵菌核病的病情进行调查和收获期测产。结果表明,播种前土壤处理加苗期灌根预防向日葵菌核病的处理,不仅防治向日葵菌核病效果最好,试验田土壤理化性状明显改善,而且向日葵的产量最高。     

威县梨园土壤抽样调查分析及其施肥建议

<正>根力多生物科技股份有限公司按照威县梨产业办的部署要求,对从河北威县及其周边11个梨园采集的11份土样进行了化验分析。根据《果园土壤有机质及养分含量高低的判断标准》,对比分析可见,这11个大的梨园土壤pH值大多数在9左右,盐碱化较严重;有机质多数在1%以下,土壤比较贫瘠;氮素普遍不足、磷养分多数在中、高水平,钾养分大部分充足或过剩,氮磷钾大量元素比例失衡。根据土壤抽样调查结果和与这些梨园负责人沟通得知,大的梨园由于前期投入多基本未见效益,致使资金缺乏,所以施肥不合理     

套餐施肥对秋月梨木栓病发生及产量、品质的影响

ABSTRACT: In order to study the effect of fertilization and pest control on improving the quality of Akizuki pear and preventing and controlling cork disease, different fertilization packages and pest control at critical period were used, the results showed that: Genliduo biological protein controlled-release fertilizer 1200 kg/hm? 2 + pure fermentative organism 4800 kg/hm 2 + 72 change-soil conditioner 750 kg/hm 2, top application of liquid fertilizer, the combination fertilization scheme of spraying 0.2% ー0.3% boric acid solution on the leaves at the beginning of Florescence and after Shaga had the best effect on preventing and curing Cork Disease of Akizuki Pear, and had obvious improvement on the physical and chemical properties of the soil in the experimental field, moreover, the Autumn Moon Pear has the highest yield.
