Several Technical Measures to Focus on in July After Cotton Topping
I. Scientific Chemical Regulation 1. Regulation According to Growth Vigour After cotton topping, generally 1 to 2 chemical regulation applications are made. The first is 3 to 5 days after topping; for fields with about 12,000 plants per 667 sq m, apply 4 to 5 grams of mepiquat chloride in 30 kg of water; for fields with more than 16,000 plants, apply 6 to 7 grams of mepiquat chloride in 40 kg of water. The second chemical regulation depends on the individual development and population size of the cotton plants, and moderate heavy regulation is carried out according to the weather, soil moisture, and the growth vigour and appearance of the cotton plants, generally per 667 sq m

How to propagate tea plants by asexual cuttings? A detailed explanation of the practical technical points
1. Propagation preparation (1) Seedbed selection. Choose a plot with fertile soil, sufficient water, good drainage, convenient transportation, easy access to materials for building a shade shed, on gentle sloping land, and sheltered from the wind. (2) Seedbed preparation. The seedbed is 1.2 m wide and 5 cm high, with the length determined by the terrain, and the bed ditch about 40 cm wide. The top layer of the seedbed is covered with 5 cm of fine red soil (sterile soil), moistened with water, and then flattened with a wooden board. (3) Building the shade shed. Use 70% or 50% shade netting, with the shed 1.6-2 m high, plant 1

Key Technical Points for Imitation-Wild Ganoderma lucidum Mushroom Bag Cultivation
The mushroom bag preparation and mycelial incubation for imitation-wild cultivation of Ganoderma lucidum are basically the same as conventional methods. The key point is to carry out the fruiting body management under suitable outdoor conditions, so as to simulate as closely as possible the environmental conditions for the growth and development of wild Ganoderma lucidum and produce higher-quality Ganoderma lucidum. The fruiting method for imitation-wild cultivation can adopt either the mushroom wall style or the raised bed style. Mushroom wall imitation-wild cultivation can be carried out in plastic greenhouses. The plastic greenhouse can be built in woodland that is sheltered from the wind, faces the sun, has good ventilation and suitable shade density, or climbing plants such as chayote and loofah can be planted around the greenhouse, with

Detailed Explanation of Log Cultivation Methods and Technical Key Points for Lingzhi (Reishi Mushroom)
① Selection and processing of logs: broadleaf trees such as oak, chestnut, Mongolian oak, peach, willow, poplar, and black locust should be used as logs. Diameters of 5-15 cm may all be used. After selecting the tree species, cut immediately, but there is no need to peel the bark; saw into logs 1 m long. If the tree species has a high moisture content, stack and dry until a wooden wedge driven into the log shows no sap exuding, then inoculation can begin. ② Inoculation period: choose a time when the temperature is 20-26°C and the relative air humidity is below 60%, which is favorable for dry cultivation and avoids

What are the key technical points for soil casing in the log cultivation of reishi mushrooms (Ganoderma lucidum)?
In reishi log cultivation, applying a soil casing layer afterward can retain moisture, increase yield, and boost profits. In addition to the same operations as ordinary cultivation, the following technical points must also be mastered: 1. Site selection and preparation. Choose a place near a water source, with convenient transportation, sandy soil, flat terrain, shelter from wind, and no pollution. Determine the corresponding width according to the cultivation scale, preferably rectangular. Remove the weeds around it, clear away branches, leaves, and weeds, plow and break up the soil finely, level it, and then make beds 1 m to 3.4 m wide. The length of the beds depends on the site, and the depth of the beds depends on the length of the logs. 2. Casing soil

Detailed Technical Points for Cultivating Reishi Mushroom with Mulberry Branches
Mulberry is a woody plant, and mulberry branches are the largest by-product of sericulture production. The degree of lignification of mulberry branches is moderate, and besides being usable as a high-quality paper raw material, they are suitable for use as a culture medium for edible and medicinal mushrooms. Mulberry branches themselves are a commonly used traditional Chinese medicinal material. The medicinal mushroom reishi (Ganoderma lucidum) cultivated with mulberry branches - mulberry branch reishi - is better than reishi cultivated with mixed wood sawdust and log wood. After mulberry branch reishi came on the market, its price is more than 50% higher than ordinary reishi. The technical points for cultivating reishi with mulberry branches are introduced as follows: 1. Cultivation techniques The artificial cultivation technical process for mulberry branch reishi is: mulberry

How to inoculate edible mushrooms? A full analysis of the technical key points
Inoculation is one of the key steps in edible mushroom production. If the inoculation technique is not up to standard, it will cause contamination by foreign microorganisms, a low survival rate, and all previous efforts wasted, let alone cultivation. Whether it is strain isolation, subculturing, or propagation, all must be carried out under sterile conditions and in strict accordance with sterile operating procedures. The specific key points are as follows: 1 Personnel quality 1.1 Inoculation personnel must possess a spirit of conscientiousness, meticulousness, self-discipline, and responsibility toward the work. 1.2 Inoculation personnel must firmly establish a sterile mindset, must not harbor any wishful thinking

Key Technical Points for Disaster Resistance and Mitigation and Spring Management of Edible Fungi
1. Clear away ice and snow, dig ditches for drainage. Promptly remove accumulated ice and snow from the top and surroundings of mushroom sheds (houses) to prevent them from collapsing. Dig drainage ditches around the mushroom sheds (houses) to keep drainage smooth and avoid rain and snowmelt attacking the mushroom substrate. 2. Stop spraying water and keep the substrate surface as dry as possible. Because at low temperatures the mycelium of edible fungi enters a dormant state, and spraying water can easily cause death. 3. Strengthen heat preservation management of mushroom sheds (houses). Small arched tunnels can be set up inside the greenhouse, and coverings such as plastic film and straw curtains can be added outside the shed for insulation and dehumidification. Use plastic

Control Methods and Technical Key Points for Edible Mushroom Mite Pests
1. Damage symptoms. Mites often gather around the mushroom blocks and bite and feed on the mycelium, so that the damaged mycelium cannot germinate. Mites severely damage the ear base and mycelium of black fungus and silver ear fungus, affecting fruiting body formation and causing rotten ears and deformed ears. 2. Control measures. Mushroom spawn culture rooms and mushroom houses should be kept away from warehouses, feed rooms, chicken coops and similar places. Inspect the spawn regularly; if mites are found, fumigate with a cotton plug dipped in 50% dichlorvos, which can kill the mites without affecting the mushroom mycelium. One week after spawning in the mushroom house, place a piece of plastic film on the surface of the substrate, and after 1~

Detailed Explanation of Key Technical Points for "Explosive Fruiting" of Edible Mushrooms
The so-called "explosive fruiting" refers to a technique in edible mushroom cultivation whereby, through artificial regulation, the mycelium colonization period is extended as much as possible to accumulate higher biological energy, so that once fruiting begins, an "explosive" momentum is formed. This transforms the original fruiting process, which lasted as long as 5 months, went through 3 to 4 flushes, and had a biological efficiency of 100%, into one where, once "explosive fruiting" occurs, the total yield is produced all at once, with biological efficiency exceeding 160%, greatly improving the input-output ratio. Key technical points of "explosive fruiting": 1. Perform virus elimination treatment on the mushroom spawn or introduce virus-free spawn that has been
