1、幼小菇蕾不噴，以免其“腫死(si)”。

2、剛采過菇或有菇殘體(ti)處不噴，以免引起細菌性病害。

3、空(kong)氣濕度過大時不(bu)噴。

4、菇棚（房）內病(bing)蟲害嚴重時(shi)不(bu)噴。浸(jin)泡(pao)法(fa)(fa)(fa)主要用(yong)(yong)(yong)(yong)于(yu)袋(dai)栽的(de)(de)(de)食(shi)用(yong)(yong)(yong)(yong)菌(jun)(jun)(jun)。在采收(shou)完(wan)1~2茬菇后(hou)，若(ruo)(ruo)栽培(pei)袋(dai)呈嚴重缺水狀態，可(ke)(ke)將其(qi)放在配好(hao)的(de)(de)(de)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)中(zhong)浸(jin)泡(pao)，直(zhi)到其(qi)恢復(fu)或接近原重量(liang)(liang)(liang)時(shi)為止(zhi)。采用(yong)(yong)(yong)(yong)浸(jin)泡(pao)法(fa)(fa)(fa)添加(jia)(jia)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)，只需在菌(jun)(jun)(jun)袋(dai)浸(jin)入營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)中(zhong)后(hou)壓上(shang)重物(wu)即可(ke)(ke)，但浸(jin)泡(pao)的(de)(de)(de)時(shi)間不(bu)應過(guo)長，若(ruo)(ruo)菌(jun)(jun)(jun)袋(dai)失水過(guo)多(duo)可(ke)(ke)以分(fen)(fen)幾次浸(jin)泡(pao)。灌穴法(fa)(fa)(fa)主要在菌(jun)(jun)(jun)床(chuang)上(shang)使(shi)(shi)用(yong)(yong)(yong)(yong)，當菌(jun)(jun)(jun)床(chuang)出菇較多(duo)、水分(fen)(fen)及養(yang)(yang)(yang)(yang)(yang)(yang)(yang)分(fen)(fen)消耗過(guo)大(da)時(shi)可(ke)(ke)采用(yong)(yong)(yong)(yong)此法(fa)(fa)(fa)。具體方(fang)法(fa)(fa)(fa)是(shi)：將菌(jun)(jun)(jun)床(chuang)按10厘米的(de)(de)(de)穴距打眼，向(xiang)菌(jun)(jun)(jun)床(chuang)上(shang)漫灌配制(zhi)好(hao)的(de)(de)(de)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)，添加(jia)(jia)完(wan)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)后(hou)覆土。濃(nong)(nong)度(du)(du)要適(shi)當營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)濃(nong)(nong)度(du)(du)過(guo)高時(shi)，不(bu)僅(jin)菌(jun)(jun)(jun)絲(si)吸收(shou)困難，而且還會妨礙甚至損害菌(jun)(jun)(jun)絲(si)。濃(nong)(nong)度(du)(du)過(guo)低時(shi)，效果不(bu)明(ming)顯，達(da)不(bu)到高產的(de)(de)(de)目的(de)(de)(de)。營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)的(de)(de)(de)濃(nong)(nong)度(du)(du)還要根據培(pei)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)料(liao)的(de)(de)(de)含水量(liang)(liang)(liang)而定。若(ruo)(ruo)培(pei)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)料(liao)的(de)(de)(de)含水量(liang)(liang)(liang)較高，應加(jia)(jia)大(da)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)的(de)(de)(de)濃(nong)(nong)度(du)(du)，減少用(yong)(yong)(yong)(yong)水量(liang)(liang)(liang)，且添加(jia)(jia)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)后(hou)要加(jia)(jia)大(da)通(tong)風量(liang)(liang)(liang)。反之，則應降低營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)的(de)(de)(de)濃(nong)(nong)度(du)(du)，增(zeng)加(jia)(jia)用(yong)(yong)(yong)(yong)水量(liang)(liang)(liang)。營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)分(fen)(fen)要全(quan)面應經(jing)常(chang)交替(ti)使(shi)(shi)用(yong)(yong)(yong)(yong)幾種(zhong)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)，這樣子實體所獲得的(de)(de)(de)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)既全(quan)面又(you)合理(li)。如果用(yong)(yong)(yong)(yong)激素刺激食(shi)用(yong)(yong)(yong)(yong)菌(jun)(jun)(jun)生(sheng)(sheng)長，則應在補充過(guo)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)之后(hou)再使(shi)(shi)用(yong)(yong)(yong)(yong)。要注意環境的(de)(de)(de)變(bian)化當氣溫達(da) 20℃以上(shang)時(shi)，菌(jun)(jun)(jun)絲(si)難以形成優質的(de)(de)(de)子實體（除(chu)高溫型食(shi)用(yong)(yong)(yong)(yong)菌(jun)(jun)(jun)品種(zhong)外），可(ke)(ke)以不(bu)添加(jia)(jia)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)。若(ruo)(ruo)培(pei)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)料(liao)已被雜菌(jun)(jun)(jun)污染，一定要先去除(chu)雜菌(jun)(jun)(jun)后(hou)再添加(jia)(jia)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)。為了防(fang)止(zhi)雜菌(jun)(jun)(jun)污染，也可(ke)(ke)在添加(jia)(jia)營(ying)(ying)養(yang)(yang)(yang)(yang)(yang)(yang)(yang)液(ye)(ye)的(de)(de)(de)同時(shi)加(jia)(jia)入一定量(liang)(liang)(liang)的(de)(de)(de)抑菌(jun)(jun)(jun)劑，以防(fang)止(zhi)雜菌(jun)(jun)(jun)滋生(sheng)(sheng)蔓延。
