密云区林地种植黑木耳品种比较试验

为筛选适合密云区林地种植的黑木耳品种,对大山黑、黑29、黑威15、黑威单片、黑山、青皮1号等6个栽培品种进行比较试验,综合分析耳片长势、耳片厚度、耳片抗性、产量和农艺学性状等指标.结果表明:黑29产量高,但子实体呈大片状偶见团状,商品性稍差;大山黑产量略低于黑29,但子实体簇生、碗状,背部有黑色筋,菌丝抗逆性较强,受温...

Comparative Experiment on Cultivars of Auricularia auricula for Cultivation under Forest in Miyun District

Abstract: In order to select the Auricularia auricula cultivars suitable for cultivation under forest in Miyun district, six cultivars of Auricularia auricula including ''Dashanhei'' ''Hei 29'' ''Heiwei 15'' ''Heiwei Danpian'' ''Heishan'' and ''Qingpi No.1'' were tested. The growth, thickness, resistance, yield and agronomic traits of Auricularia auricula were comprehensively analyzed. The results showed that ''Hei 29'' had high yield, but its fruiting bodies were large and flaky and occasionally clumpy, and commodity were slightly worse. The yield of ''Dashanhei'' was slightly lower than that of ''Hei 29'', but the fruiting bodies were clustered and bowl-shaped, with black ribs on the back. The mycelia had strong stress resistance and were less affected by temperature changes. The ears were moderate in size and thickness, and output of ear was high and uniform, the yield of fresh ear and dry ear were higher than that of other cultivars at the same cultivation condition. It was concluded that ''Hei 29'' and ''Dashanhei'' had outstanding comprehensive performance, which were suitable for cultivation under forest in Miyun district and had good promotion values.
