微生物菌肥菌剂对番茄生长发育和产量品质的影响

为了探究微生物菌肥和微生物菌剂对番茄生长发育和产量品质的影响，以“桃星”番茄为试验对象，设置普通商品有机肥+灭菌后的微生物菌剂(CK)、普通商品有机肥+微生物菌剂(T1)、微生物菌肥+灭菌后的微生物菌剂(T2)、微生物菌肥+微生物菌剂(T3)4个处理。在膨果初期测定番茄植株株高、茎粗和叶片SPAD值，膨果期计算番茄每层膨果挂果数、产量和品质(可溶性固形物、可滴定酸、糖酸比和Vc含量)。结果表明，微生物菌肥能显著地促进番茄植株生长发育，施用微生物菌肥的处理(T2和T3)的植株茎粗均达到13 mm以上，株高比对照(CK)稍有增加；微生物菌肥+微生物菌剂(T3)增产效果最好，总产量较对照(CK)提高13.6%;第3-5膨果期果实的可溶性固形物较对照分别提高了3.21%,3.87%和4.55%,糖酸比分别较对照提高了7.63%,10.1%和12.9%,Vc含量分别较对照提高了6.27%、7.67%和8.10%。综上，施用微生物菌肥和菌剂能促进番茄植株生长，增加番茄产量，提高果实品质，对产量和品质的促进作用在番茄挂果期的中后期表现出来。

Effects of bio-organic fertilizer and microbial agent on the growth,yield and quality of tomato

In order to study the effects of bio-organic fertilizer and microbial agent on the growth development,yield and quality of tomato,"Taoxing"tomato was selected in an experiment with four treatments:common organic fertilizer+sterilized microbial agents(CK),common organic fertilizer+microbial agent(T1),bio-organic fertilizer+sterilized microbial agent(T2),and bio-organic fertilizer+microbial agent(T3).The plant height,stem diameter and blade SPAD value of tomato were investigated at the initial stage of fruit expansion.The fruit number,yield and fruit quality of tomato in each layer were analyzed at the fruit expansion stage.The results showed that bio-organic fertilizer significantly stimulated tomato growth.Compared with CK,when no microbial agent was applied at the early stage of fruit expansion,the stem diameter of treatment T3 and T4 were more than 13 mm,and the plant heights were relatively increased.The total yield of bio-organic fertilizer+microbial agent increased by 13.6%.The soluble solids of T1,T2 and T3 treatments increased by 3.21%,3.87%and 4.55%,the sugar acid ratio increased by 7.63%,10.1%and 12.9%,and Vc increased by 6.27%,7.67%and 8.10%,respectively.The combination of bio-organic fertilizer and microbial agent would significantly increase the growth,yield and quality of tomato,especially in the middle and late period of tomato fruit bearing period.
