- 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。
- 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 than 158.43 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 was 1.29 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 bag-controlled 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.
