摘 要：
[目的]本文旨在研究贵州木霉生物有机肥对番茄种植的促生作用及其对土壤养分、土壤酶活性及微生物数量的影响。[方法]试验于江苏盐城大丰设施盐土大棚内进行,以‘合作903’番茄和贵州木霉NJAU4742为试验材料,共设5个处理:不施肥处理(CK)、农户习惯施肥处理(CF)、75%的农户习惯施肥量配施木霉NJAU4742生物有机肥处理(BF)、75%的农户习惯施肥量配施普通有机肥处理(OF)、75%的农户习惯施肥量配施木霉孢子悬液处理(SS)。[结果]相对于CF处理,BF处理番茄增产15%以上,且番茄果实中蛋白质、维生素C和可溶性糖含量显著提高,硝酸盐含量降低。接种木霉的BF和SS处理,根际土壤中木霉的数量显著提高,土壤中的微生物群落发生改变。BF和OF处理显著提高土壤脲酶、磷酸酶和过氧化氢酶活性。此外,土壤中速效养分含量也显著增加。[结论]减施25%的化肥同时配施功能木霉菌NJAU4742制成的生物有机肥可以通过调控土壤养分有效性、土壤酶活性和土壤微生物区系来改善盐土的可耕种性,从而提高番茄的产量和品质。

摘 要：
[Objectives]This research was to study the capacity of a Trichoderma-enriched bio-organic fertilizer to stimulate tomato growth,soil nutrients availability,soil enzyme activities and soil microflora under field conditions. [Methods]The experiment was carried out in Dafeng protected saline soil cultivation base,Jiangsu Province,using‘Hezuo 903'tomato and Trichoderma guizhouense NJAU4742 train. There were 5 treatments: non-fertilizer application( CK),100% chemical fertilizer( CF),75% chemical fertilizer plus Trichoderma-enriched bio-organic fertilizer( BF),75% chemical fertilizer plus organic fertilizer( OF),75% chemical fertilizer plus Trichoderma spore suspension( SS). [Results]The BF significantly stimulated tomato biomass accumulation at an early stage and enhanced the tomato yield( by 15%) and quality( including protein,Vitamin C and soluble sugar contents) when compared with the CF-treated ones. Inoculation with the Trichoderma either alone( SS) or as the form of biofertilizer( BF) would cause the decrease of total bacteria and fungi in soil over the control( CF or CK). The BF and OF significantly increased the activity of urease,phosphatase and catalase in soil. In addition,available nutrient in soil had also increased observably. [Conclusions]The efficacy of BF for enhacing tomato growth,yield and quality grown may be due to the enhanced soil nutrients availability and the increased activity of soil enzymes,and the change of microflora,which improves the arability of coastal mud significantly.
