菇体在发育过程中,尚未达到商品菇所需要标准,其菌盖部分就过早展平,此现象称早开伞。早开伞的菌盖特别容易脱落形成光柄菇,影响质量和产量。本文主要介绍早开伞的发生原因及其防治措施。 (一)栽培新品种某些早生型品种,生理成熟度早,菌盖较易开伞。因此,对于易开伞的品种一般不宜使用;在使用产量高、优点多的易开伞品种时,管 Mushroom body in the development process, has not yet reached the required standard of mushrooms, the cover part of the premature flattening, this phenomenon that early open parachute. Early opening of the mushroom cap is particularly easy to fall off the light-shaped mushrooms, affecting the quality and yield. This article describes the reasons for the early open umbrella and its prevention and treatment measures. (A) Cultivation of new varieties Some early-type varieties, early maturity of physiology, cap easier to open umbrella. Therefore, for the easy-to-open varieties are generally not suitable for use; in the use of high yield, the advantages of more easy to open umbrella varieties, the tube
