摘　　要：以瑞康盾微生物菌剂为试验材料,研究了微生物菌剂对秋季连作西瓜生长发育和产量品质的影响。以京嘉301西瓜为试验对象,设置常规施肥+清水为对照CK,常规施肥+瑞康盾微生物菌剂为处理T。在微生物菌剂每次施用10 d后,测定其茎粗、主蔓长、叶片数、节间长、第一雌花节位;在果实采收期,称取单果重,计算小区产量,折合成667 m~2产量,测量其皮厚、纵径、横径,计算果形指数,测定其中心和边缘部位可溶性固形物含量。结果表明,瑞康盾微生物菌剂对秋季连作西瓜植株的生长能够起到一定的促进作用,T的植株平均茎粗、节间数、叶片数、主蔓长和节间长比CK均有提高;增产效果较好,增产率达15.16%;果实的平均皮厚较CK增加了6.90%,中心和边缘部位可溶性固形物含量较CK分别提高了1.2和0.1百分点。综上,瑞康盾微生物菌剂能够促进秋季连作西瓜植株的生长,增加产量,提高果实品质。Using Ruikangdun microbial inoculants as experimental materials,the effects of microbial inoculants on the growth,development,yield,and quality of autumn continuous cropping watermelon were studied.Using Jingjia 301 as the experimental object,conventional fertilization and clean water as the control CK,conventional fertilization and Ruikangdun microbial agent as the treatment T.After 10 days of each application of microbial agents,stem diameter,main vine length,number of leaves,internode length,and first female flower node position were determined;During the fruit harvesting period,the individual fruit weight was detected and the yield of the plot was calculated,then the yield of 667 m~2 was converted.The peel thickness,longitudinal diameter,and transverse diameter were measured,the fruit shape index was calculated,and the soluble solid content in the center and edge parts were measured.The results showed that Ruikangdun microbial inoculum could promote the growth of autumn continuous cropping watermelon plants to a certain extent.The average stem diameter,number of internodes,number of leaves,main vine length,and internode length of T plants were higher than those of CK plants.The yield increase effect is good,with a yield increase rate of 15.16%.The average peel thickness of the fruit increased by 6.90% compared with CK,and the soluble solid content in the center and edge parts increased by 1.2 percentage points and 0.1 percentage points respectively compared with CK.In summary,Ruikangdun microbial inoculum can promote the growth of autumn continuous cropping watermelon plants,increase yield,and improve fruit quality.
