对出菇不整齐的水分管理,笔者实践表明,以用水量大次数少的喷水方法较好。若以少量多次喷水,就象持续的毛毛细雨,不但会造成小菇水肿黄,留大留不住小,而且违背了干干湿湿的自然水分管理原则,容易导致病虫的发生。小菇水肿黄的原因,就是小菇盖被水珠膜完全覆盖阻止呼吸而死。采用大量少次喷水法,菇蕾和小菇盖有一定的无积水期,从而能充分完成排出水分和二氧化碳,吸收氧气等生理需要。 在栽培中我们可观察到,大量少次喷水在幼菇上不会比少量多次喷水多留一点水,而在大菇上则会多留一些水,特别是菌盖中间有凹陷的品种,但大菇吸水量大而快。还有些品种,菌柄基部有绒毛,具有储水供水的自我调节功能。当然,大量喷水要注意轻喷,不宜冲、泼浇等,以免造成机械伤害而引起水肿黄。少次的标准是以小菇盖无积水至略干再喷下一次水为准。有 Irregular fruiting fruiting management, the author shows that in order to use less water spray method is better. If a small amount of water spray, like continuous drizzle, will not only cause small mushroom edema yellow, stay big can not retain small, but also contrary to the wet and dry natural moisture management principles, easily lead to the occurrence of pests . Small mushroom edema yellow reason is that mushroom cover is completely covered with water film to prevent breathing and death. Adopt a large number of less water spray method, mushroom buds and mushroom cover a certain period of no water, which can fully discharge the water and carbon dioxide to absorb oxygen and other physiological needs. We can observe in the cultivation, a large number of times less water spray on the young mushroom will not be more than a small amount of water more than a few more water, but will stay on the mushrooms to stay some water, especially in the middle of the cap with concave varieties, However, large mushrooms absorb water quickly. There are some varieties, base stigma fluffy, with water storage water self-regulating function. Of course, a lot of water to pay attention to light spray, should not be washed, poured pouring, etc., so as to avoid mechanical damage caused by edema yellow. Less frequently, the standard is to cover with little mushroom water to slightly dry and then spray a water subject. Have
