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.
