Ganoderma lucidum physiological disease
Symptoms of physiological disease, it will grow deformed zhizhi, mycelium growth or poor growth atrophy, there are leggy phenomenon.
Etiology Due to improper management in cultivation, resulting in malnutrition of the body; excessive or low temperature in the cultivation room, poor ventilation; excessive or low pH of the culture material; unfavorable lightness; poor light coordination; Harmful gases; improper use of pesticides and growth regulators. The hyphae are not mature and prematurely covered with soil. The proportion of nitrogen contained in the culture material is too high, which can easily cause mycelium growth.
Control methods
(1) Strengthen cultivation management, timely ventilation and ventilation, maintain proper temperature and humidity, and pay attention to environmental sanitation.
(2) Choose high-quality strains; reasonably prepare the culture materials, and require proper nitrogen content. The commonly used wheat bran or rice bran should not exceed 20% in general so as to prevent the hyphae from being prolonged;
(3) The boring machine can be sprayed with lime water ranging from 1% to 3%. After the surface is slightly dry, coverings such as branches and branches can be covered, and the hyphae can also be prevented from becoming excessively long.
(4) Select suitable pesticides and growth regulators to prevent pesticide poisoning.
