In spring, fully utilizing natural climate condition and enhancing the management in fruiting period can not only increase output by a large margin, but also can reduce the occurrence rate of all diseases and pest and increase total benefit.
A. Artificial temperature-increasing: when greenhouse temperature is under 8 degrees, Oyster mushrooms will have slow growth trend, when the temperature is under 4 degrees, the growth will be inhibited. In order to guarantee the normal growth of Oyster mushroom, it is best to keep greenhouse temperature between 10 and 20 degrees, people could adopt hand firing or other measures to increase temperature. During this period, Carbon dioxide and other harmful substances should be discharged in time.
B. Reasonable humidity-increasing: in fruiting period of spring, the suitable growth temperature is between 10 and 25 degrees, people could increase relative air humidity to about 85%, reduce direct sunlight and prevent too high temperature and too humidity in fruiting environment. People should also spray water for 1 to 3 times in accordance with the change of temperature to guarantee the humidity in greenhouse, but excessive water-spraying should be avoided and it is proper to keep relative air humidity of greenhouse under 95%.
C. Increase ventilation: ventilation is contradictory with heat preservation. In low temperature, Oyster mushrooms can’t grow, but poor ventilation will cause sick and abnormal mushrooms. So, people should coordinate heat preservation with ventilation to guarantee normal growth of Oyster mushroom. In general situation, people should increase ventilation in high temperature and reduce ventilation in low temperature.
D. Moderately use production promoter: there are various production promoters in the market, their mixing methods are manifold. People should use them in accordance with specified dosage.
E. Supplement moisture of mushroom bags in time: in fruiting period, direct exposure on both sides of compost will cause constant losing. It will affect normal fruiting when loosing half of moisture in compost. Normally, after fruiting two flushes, surface will become hydropenic and dry, which can cause cracks and become hard to get fruited. On that occasion, farmers should supplement moisture in time. At present, common methods on moisturizing are Soaking Supplement Method and Pressure Supplement Method. Soaking Supplement Method is to pour prepared nutrient solution to pool or special vessel to retain water, use iron bar to punch on surface of mushroom bag. Soaking should be remained for 4 to 8 hours generally and make water-soaked weight reach 90% of original weight. Pressure Supplement Method is to use specialized moisturizing needle of Oyster mushroom that is linked to agroatomizer, one side of this kind of needle presents needle-shape of infection, other side is linked with water let, people insert moisturizing needle in compost and press the pressure rod of atomizer, so nutrition of atomizer will be injected to mushroom sacks of Oyster mushroom by certain pressure, which plays the role of supplementing moisture and nutrition. In general, each bag needs 3 holes, people can also equip water pump to increase water pressure, utilize multiport water replenisher to speed up the efficiency of moisturizing.
F. Timely picking: when finding white nap, people could pick Oyster mushrooms ahead of time , too late picking will cause aging, lower resistibility, lower crush capacity, lower putrescibility and quality reduction in mushroom context.
