摘要
通过设施栽培试验 ,结果表明石刁柏 (AsparagusofficinalisL .)的产量比露地常规栽培提高15 .8% ,一级品比率提高 89.0 % ,产值增加 144 .2 % ,采收期延长 90d。由于设施栽培避开了自然雨水对石刁柏的直接影响 ,降低了田间湿度 ,在减少病害防治次数及用药量的同时 ,茎枯病平均发病率从 74.8%下降到 10 .0 %。
The experiments in the protected culture of asparagus (Asparagus officinalis L.) showed that the yield increased by 15.8% over that of conventional field culture,the rate of grade A products increased by 89.0%,the output value increased by 144.2% and the time of picking asparagus increased by 90 days.Since the protected culture mode avoided direct effect of rainwater on asparagus and decreased field moisture,the times of disease control and the dose of drug reduced and the mean incidence of the stem blight also decreased from 74.8% to 10.0%.
