Be on strict guard against physiological diseases in edible mushroom cultivation
Wild mushroom: caused by high nitrogen, high moisture and high temperature in the substrate. Control methods: reduce the nitrogen content of the substrate and raise the pH value of the substrate to 8-9. Green mold: caused by a too low pH value, poor ventilation of the substrate bags, and excessive bag temperature leading to a stuffy stack. Control methods: raise the pH value to 8-9, strengthen microporous aeration to promote mycelial growth, and prevent stuffy stacks from high humidity. Dead mushrooms: shortly after pinning, large numbers of small mushroom pins sometimes shrink, turn yellow and even die. This is mainly because the temperature of the substrate bags in the mushroom stack is too high and the heat from mycelial metabolism cannot

Detailed Explanation of Rice-Fish-Loach Ecological Agriculture Engineering Technology
1. Environmental conditions of the production area: a good ecological environment, far from pollution sources, good air; high, thick and compact paddy field ridges, relatively clayey soil, relatively high soil fertility, and paddy fields with sustainable development capacity; good irrigation and drainage conditions, relatively sufficient water sources, and fresh water quality. 2. Paddy field engineering facilities: dig a ring-shaped ditch around the paddy field, with a ditch width of 1 m and a depth of 0.5 m; surround the field ridges with anti-escape plastic sheeting (40-50 cm above ground, buried 20-30 cm underground); install double-layer anti-escape blocking nets at the water inlet and outlet. 3. Rice, river crab,

What are the control methods for common physiological diseases of edible fungi?
1. Mycelial overgrowth After inoculation of edible fungi, vegetative growth is excessive, and the fluffy mycelium grows densely. After casing soil is applied, it often "drills" out of the ground and forms a mycelial mat. This situation is related to the characteristics of the strain and environmental conditions. Low water content in the soil layer, excessively high nitrogen content in the compost, poor ventilation, and excessively high air humidity all easily cause mycelial overgrowth, producing the phenomenon of "mycelium emergence." Common control methods: select high-quality strains; pry loose and break up the hardened mycelial mat; cover with fine soil, increase ventilation, and lower relative air humidity; use heavy watering to promote mycelial

Wuchang rice drinks fruit juice and takes calcium tablets to grow into ecological rice
Have you ever heard of a rice nutrient solution that people can drink? The fruit enzyme made by Liang Yingfen of Wuchang City, Heilongjiang Province, is drinkable by people. She used her homemade nutrient solution to replace rice foliar fertilizer, and the organic rice she produced was praised by experts for its high nutritional value. Liang Yingfen is a Korean ethnic farmer from Minle Township, Wuchang City. A rice blast disease in 2004 nearly wiped out all 6 mu of rice in her family. After many years of working with rice, Liang Yingfen realized that continuing to use chemical fertilizers and pesticides was very dangerous. The soil was getting poorer the more it was farmed, crop diseases and pests were increasing, and especially the residues of chemical

Detailed Explanation of Key Technical Points for Soft-shelled Turtle-Rice Ecological Rotation
In recent years, China's soft-shelled turtle farming industry has developed rapidly. Adopting the soft-shelled turtle-rice rotation model can achieve rice cultivation without fertilization, while planting rice can also improve the bottom substrate of turtle ponds and reduce the occurrence of turtle diseases. Zhejiang Qingxi Soft-shelled Turtle Industry Co., Ltd. began conducting soft-shelled turtle-rice rotation experiments in 1999, and in practice summarized the ecological rotation model of "raising soft-shelled turtles for 2-3 years, planting one season of rice," which has been promoted and applied in production. 1. Construction of Rice-Planting Turtle Ponds. Each pond has an area of more than 3 mu, with the largest reaching

Morphological Characteristics and Control Techniques of the Rice Skipper (Pelopidas mathias)
The straight-lined skipper belongs to the order Lepidoptera, family Hesperiidae. Adults have a body length of 17-19 mm and a wingspan of 36-42 mm. The body and wings are both dark brown with a golden sheen, and the antennae are club-shaped. The forewings have 8 white semi-transparent markings arranged in a semi-ring; the hindwings also have 4 white markings arranged in a straight line. The egg is hemispherical, slightly depressed at the top, with a hexagonal reticulated surface pattern; it is light green when first laid and purplish-red before hatching. Larvae generally have 5 instars. Newly hatched larvae have a black head and a grayish-green body; after the 2nd to 3rd instar, the head color gradually fades to light brown. Mature larvae have a body length of

A Detailed Guide to the Morphological Characteristics of Goji Berry and Its Suitable Growing Environment
[Morphological Characteristics] The goji berry (Lycium chinense) is a deciduous shrub, 1.5-2 m tall. The bark is grayish-white and smooth when young; dark brown with furrowed cracks when old. The crown is open and spreading, with slender branches that usually bend and droop at the tips and often become thorn-like. The leaves are alternate or clustered in groups of several, ovate-lanceolate or narrowly obovate, with entire margins. The flowers are solitary or clustered in the leaf axils, with pink or pale purplish-red corollas. The berry is elliptical or ovoid, turning red or orange-red when ripe. [Suitable Environment] It prefers a cool climate, likes light, and is cold-tolerant, drought-tolerant, and salt-alkali-tolerant, with strong adaptability. It does best in deep, fertile

What pharmacological effects does goji berry have? A detailed explanation in one article
Goji berry is a deciduous shrub, with a tree height of 1.5 m-2 m and a growth period of 35-50 years. It bears small eggplant-red or pale red flowers and produces bright red fruits the size of jujube pits. It is a rare and precious traditional Chinese medicinal herb and a fine tonic, with effects of tonifying, treating deficiency, anti-aging, protecting the liver, and promoting and regulating immune function. As a medicinal material, goji berry has a long history in China. In addition to the records in the Book of Songs, Su Dongpo of the Song Dynasty wrote in the poem "Xiaopu Goji": "Roots, stems, flowers, and fruits, nothing is discarded when gathered,"
