تأثير أغطية اللدائن في تعقيم التربة بالطاقة الشمسية و الزراعة على الأغطية في نمو و إنتاجية الخيار Cucumis sativus L. و الشمام Cucumis melo L. تحت ظروف الزراعة المحمية

الملخص EN

Soil solarization with one or two layers of transparent and one layer of black plastic sheets were compared with methyl bromide fumigation treatment, under greenhouse conditions on cucumber (Cucumis sativus PS116095 hybrid) in site 1.

Black mulches were used for soil solarization for two months in rows; the same sheets were used as a soil mulch during planting of muskmelon plants (Cucumis melo var Dikti RZ F1) for commercial production in multispan plastic greenhouse in site 2.

Results showed that soil solarization with plastic sheets were effective against soil inhabiting pests and pathogens, especially root knot nematode Meloidogyne spp.

and annual and perennial weeds e.g.

Bermudagrass Cynodon dactylon.

Increase in plant growth, flowering and yield was significantly different between treatments.

Furthermore, results indicated that there were significant differences in plant parameters (growth, height, earliness, yield production of muskmelon) between mulched and non-mulched plants.
