摘　　要：以果桑(Morsu alba L.)品种大十(M.alba cv.Big ten)为材料,分别覆盖聚乙烯白色地膜、黑色地膜和银黑反光膜,在果桑萌芽开花前于行内覆盖,比较了开花前不同地表覆膜对果桑果实桑白果病发病率以及果实品质的影响。结果表明,不同地膜覆盖均能显著降低果桑果实桑白果病的发病率,对成熟果实的可滴定酸含量有降低的趋势,同时也显著降低了果实可溶性固形物、花青素和抗坏血酸的含量。说明地表覆膜可以有效预防桑白果病的发生,但是对果实品质的影响尚待进一步试验确认。To study the influence of different surface mulching before flowering on the white mulberry（Morsu alba L.） disease and fruit quality of mulberry, with M. alba cv. Big ten as tested material, polyethylene mulch film, black and silver black reflective film, respectively, were tightly coated before bud sprouting and flowering of mulberry. The study found that, under different film covering, infection rates of the white mulberry disease and titratable acid（TA） in ripe mulberry fruit reduced significantly. Meanwhile, several beneficial metabolites, such as total soluble solids（TAA）, anthocyanin and ascorbic acid dropped significantly. The surface coating could effectively prevent the happening of the white mulberry disease; but the effects on fruit quality is yet to be further confirmed.
