不同耕作模式对大棚甜椒生长效应研究

Effects of different tillage patterns on the growth of sweet pepper under greenhouse conditions

在闽南大棚甜椒种植的夏季休耕期,采用土壤泡水、种植水稻实行水旱轮作和种植绿肥作物田菁还田3种耕作模式对土壤进行处理,结果表明:3种耕作模式均可有效促进大棚甜椒的生长,减少甜椒病虫害的发生,提高甜椒的产量和品质,其中种植水稻实行水旱轮作和种植绿肥作物显著和极显著提高了甜椒产量,同时降低土壤盐化程度,提高了土壤肥力。

Three tillage patterns,including water soaking soil,paddy-upland rotation with rice,and planting green manure crop Sesbania cannabina for returning,were conducted to treat the soil in the summer fallow period of sweet pepper in southern Fujian.The results showed that all of three tillage patterns could effectively promote the growth of sweet pepper,decrease occurrence of pests and diseases,and improve the yield and quality of sweet pepper.Among them,the tillage methods of paddy-upland rotation with rice and planting green manure crop significantly and very significantly increased the yield of sweet pepper respectively,at same time,decreased the soil salinization,and improved the soil fertility.
