Causes and Control Methods of Hollow Stems with White Cores in Mushrooms
Symptoms: The mushroom stem tissue is not solid, with a white, loose pith appearing inside; after the fruiting body dries or is cooked, the pith shrinks or falls away, becoming hollow. Causes: This is mainly due to improper water management. If the air humidity in the mushroom house is low and the soil layer humidity is low, especially when the water content of the coarse soil layer is insufficient, the rapidly growing fruiting bodies cannot obtain sufficient water from the soil layer, and consequently the transport and supply of nutrients are also reduced. Combined with the continuous evaporation of water from the fruiting bodies themselves, this causes a lack of water in the middle of the stem and loose tissue, thereby

High-yield and high-benefit "garlic with beans" planting achieves two plantings and three harvests
Interplanting garlic with soybeans is one of the resource-saving agricultural cultivation models currently promoted by the Fujin City Agricultural Technology Extension Center. It rationally matches and combines crops according to their growth patterns and habits, forming a mutually beneficial symbiotic relationship: the nitrogen fixation by soybean rhizobia increases the soil's nitrogen content, so the garlic does not suffer nutrient deficiency, which benefits the garlic's later growth and bulb enlargement. The garlic plants, especially the garlic roots, have a strong pungent taste in the soil, which strongly inhibits and kills various soybean pests, viruses and pathogens. Because
