【摘要】 以抗TY病毒番茄品种"迪粉尼"为试材,采用小区试验法,研究了增氧型袋控缓释肥对土壤养分、土壤酶活性及番茄生长的影响,以期为生产中增氧方法提供参考依据。结果表明:增氧型袋控缓释肥增氧效果明显,增氧型袋控缓释肥施肥处理（ABCRF）与袋控缓释肥处理（BCRF）和传统施肥处理（TF）相比,土壤铵态氮含量提高了120%和53%,硝态氮含量相同,均降低27%,速效磷含量维持在60.34 mg·kg^-1以上,速效钾维持在158.43 mg·kg^-1以上,且养分浓度稳定。过氧化氢酶、脲酶、脱氢酶取样期内表现为先升高后降低趋势,但每次取样均以ABCRF处理最高,第一穗果坐果期最高,分别达1.29 mL·g^-1、0.15 mg·g^-1·d^-1、4.90 mg·g^-1·d^-1。由此可知,增氧型袋控缓释肥具有普通袋控缓释肥养分释放平稳的特点,且显著提高了土壤中铵态氮含量,提高了土壤速效磷、速效钾含量,提高了土壤中过氧化氢酶、脲酶、脱氢酶活性。增氧型袋控缓释肥满足了温室番茄施肥省工要求,同时解决了温室内土壤缺氧的问题,推广价值高。更多还原

【Abstract】 Greenhouse tomatoes were used as materials, field experiments were carried out to clarify the effects of aeration bag-controlled release fertilizer on soil nutrition and enzyme activities and growth for tomato in plastic greenhouse to provide a reference for the application and popularization of this fertilizer in greenhouse production.The results showed that the aeration bag-controlled release fertilizer had a remarkable effect of oxygen aeration.The treatment of aeration bag-controlled release fertilizer（ABCRF） compared with the treatment of bag-controlled release fertilizer（BCRF） and the treatment of traditional fertilizer（TF） increased the ammonium concentration 120% and 53%decreased the concentration of nitrate concentration 27% the same.The ABCRF kept available phosphorous stable and higher than 60.34 mg·kg^-1,available potassium stable and higher than158.43 mg·kg^-1.Between sampling period the ABCRF had the highest catalase activity,urease activity and dehydrogenase activity sampled at the first cluster fruit setting and the value was1.29 mL·g^-1,0.15 mg·g^-1·d-1,4.90 mg·g^-1·d-1 respectively.The activity of catalase,urease and dehydrogenase present the tendency that increased firstly and then decreased.The aeration bagcontrolled release fertilizer had the characteristic of nutrition release stable that like the bag-controlled release fertilizer and it significantly increased soil ammonium,available phosphorus and available potassium concentration,increased the activity of catalase,urease and dehydrogenase.The aeration bag-controlled release fertilizer simultaneously solved fertilizer and aeration,had low cost and was worthy to be popularized.更多还原
