摘要

Three crops of cucumber were grown in succession in beds by use of trickle irrigation, plastic film mulch, and soil chemical treatments over a 17-month period, including a fallow winter season. Total yield for the three crops was highest (1208 quintals/ha) in film-mulched plots treated with MBR-CP, and next-highest in film-mulched plots treated with DD-MENCS (1094 quintals/ha); total yield was only 456 quintals/ha in film-mulched control (untreated) plots. Yield in untreated film-mulched plots was 256% of that in untreated unmulched plots (178 quintals/ha). Plant growth and yields were greatest when populations of nematodes and soil-borne fungi were suppressed to very low levels. The residual control by soil treatments lasted longest on Meloidogyne incognita and Fusarium solani.
