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 disease and pests and increase total benefits.
A. Artificial warming up: when the 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 in between 10 to 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 from 10 to 25 degrees, people could increase relative air humidity in about 85%, reduce direct sunlight and prevent the too high temperature and too humidity in fruiting environment. People should also spray water for 1 to 3 times in accordance with changes of temperature to keep the humidity in greenhouse, but excessive water-spraying should be avoided and it is proper to keep relative air humidity of greenhouse in 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 promoter in the market, mixing methods are manifold. People should use in accordance with specified dosage.
E. Supplement moisture of mushroom bags in time: in fruiting period, direct exposure on both sides of compost will make constant losing. It will affect fruiting when loosing half of moisture in compost. Normally, after fruiting two flushes, surface will become hydropenic. Dry environment will 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 make holes on surface of mushroom bag. Soaking should be remained for 4 to 8 hours in general 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 should insert moisturizing needle in compost and press the pressure rod of atomizer, so nutrition of atomizer will be injected to bags of Oyster mushroom by certain pressure and plays the role of supplementing moisture and nutrition. In general, each bags needs 3 holes, people could also equip water pump to increase water pressure, utilize multiport water replenisher to speed up the efficiency of moisturizing.
F. Timely picking: people can pick Oyster mushrooms ahead of time when finding white viliform, too late picking will cause the aging, lower resistibility, lower crush capacity, lower putrescibility and quality reduction in mushroom context.
