Physiological diseases of Ganoderma lucidum
Due to the action of abiotic factors, diseases often occur due to the imbalance of physiological metabolism of Ganoderma lucidum. Symptoms of physiological diseases, the growth of deformed Ganoderma lucidum, hyphae stop growing or poor growth of the phenomenon of atrophy, but also the phenomenon of overgrowth. The etiology is due to improper management in cultivation, resulting in sesame malnutrition; too high or low temperature in the cultivation room, poor ventilation; too high or low water content in the culture material or uncomfortable ph value; uncoordinated light; excessive concentration of harmful gases in the border bed; use of pesticides and growth regulators

What is the physiological fruit drop of persimmon?
What is the physiological fruit drop of persimmon? Please introduce the causes and methods of prevention and control of physiological fruit drop of persimmon as follows: first, the factors of physiological fruit drop of persimmon.

Control of physiological Diseases of Pleurotus ostreatus
Pleurotus ostreatus has the characteristics of wide adaptability, strong stress resistance, wide sources of cultivation raw materials, simple cultivation techniques and high economic benefits. The production of Pleurotus ostreatus has developed rapidly in our county in recent years, but it often produces a variety of non-infectious physiological diseases due to poor management, resulting in a reduction in production and directly affecting the economic benefits of Pleurotus ostreatus production. Based on years of practical experience in production, we summarized several main physiological disease symptoms and control techniques that often occur in the production of Pleurotus ostreatus. The mycelium grows excessively in the production of Pleurotus ostreatus, and the mycelium is often dense because of the excessive growth of hyphae.

Beware of physiological diseases of edible fungi
Wild mushroom: caused by high nitrogen, high moisture and high temperature of culture material. The prevention and cure method: reduce the nitrogen content of the culture material, and increase the pH value of the culture material to 8 Mel 9. Green mold: due to low pH value, poor ventilation of material bag, high bag temperature leads to stuffy stack. Prevention and treatment methods: increase the pH value to 8mur9, strengthen micropores to increase oxygen to promote bacteria, and prevent high humidity from stacking. Dead mushroom: shortly after budding, sometimes a large number of small mushroom buds atrophy, turn yellow and even die. This is mainly due to the high temperature of the palletizing bag and the lack of heat in the process of mycelium metabolism.

Causes of Bud and Boll shedding in planting Cotton
First, physiological shedding accounts for about 60-70% of the total shedding of buds and bolls, mainly due to improper management and diseases and insect pests, resulting in plant malnutrition and insufficient nutrition needed for bolls. There are mainly the following three aspects: 1. Root system dysplasia and water absorption.

Control of physiological Diseases of Mushroom
Mushroom is more sensitive to the environment, poor cultivation environment, will hinder its normal growth and development, resulting in a variety of abnormal phenomena, resulting in the reduction of mushroom yield and quality. The common physiological diseases of mushroom are mycelium growing, hard umbrella opening, thin skin opening early or Pleurotus ostreatus, empty root Pleurotus ostreatus and so on. The symptoms of excessive growth of hyphae are introduced as follows: after the mushroom bed is covered with soil and transferred water, the mushroom villi hyphae will continue to grow to the fine soil surface, and in serious cases, a kind of fine and impervious quilt will be formed, thus delaying the mushroom emergence time and reducing the mushroom.

Introduction: utilization rate and physiological function of phosphate fertilizer
The utilization rate of phosphate fertilizer is much lower than that of nitrogen fertilizer and potassium fertilizer. In China, the utilization rate of phosphate fertilizer is generally within the range of 10% to 25%. The utilization rate of legume is higher in vegetable crops. There are two main reasons for the low utilization rate of phosphate fertilizer: the first reason is that phosphate fertilizer is fixed in the soil, regardless of water solubility or wolfberry solubility.
