The main purpose is to improve site conditions and sanitation, create a favorable environment for young tree growth, and promote the young stand to close its canopy as soon as possible. 2. Forest land enclosure. To shorten the forest cultivation cycle, comprehensive enclosure measures are adopted for black locust clearcut sites. Cattle and sheep specifically browse the tender shoots of young trees and cause extremely severe damage to black locust sprouts, so dedicated personnel must be assigned for supervision and protection, grazing must be strictly prohibited; mowing and firewood gathering are strictly prohibited,

How to Prevent and Treat Deformed Mushrooms? A Detailed Guide to Practical Methods
Deformed mushrooms manifest in many different forms. The most common ones in production mainly include: "landmine mushrooms", "hollow mushrooms", "big-bottom mushrooms", "hard opening and early opening", "red root", and "water rust spots". The main cause of "landmine mushroom" formation is that the casing soil material is too coarse, the soil is rather hard, the casing layer is thick, the surface layer of the casing contains less water, while the temperature and humidity conditions of its lower part and the substrate are suitable for fruiting body initiation and growth, so fruiting bodies tend to differentiate and form on the material surface or in the middle and lower layers of the casing soil, and then push through the soil surface.

How to Safely Transport Live Fish? A Full Breakdown of Practical Methods
1. Sealed transport: Sealed transport places the fish and water in a sealed, oxygen-filled container for transport. Its characteristics are small volume and easy portability; for general adult fish transport, within 8 hours there is no need to change the water midway, the seal is tight, and the survival rate is high. A single oxygen fill can keep fry alive in the container for more than 20 hours, and it is even more convenient for long-distance transport of large quantities of fry and fingerlings. Methods such as oxygen-filled sealed transport in plastic bags and oxygen-filled sealed transport in plastic buckets can be used. 1. Oxygen-filled sealed transport in plastic bags: Fill the plastic bag with clean clear water, with the water volume accounting for 1/3 of the bag's total capacity

How to Store and Preserve Fresh Peaches? A Detailed Guide to Practical Techniques
I. Cold storage. Peaches are prone to cold injury during low-temperature storage, and there is a risk of freezing at -1°C. Therefore, the suitable storage temperature for peaches is 0°C, and the suitable relative humidity is 90%-95%. Under these storage conditions, peaches can be stored for 3-4 weeks or longer. However, when peaches are stored at low temperature for a long time, the flavor gradually becomes bland. Long-term low-temperature cold storage will cause cold injury to the peaches, with browning of the flesh. In particular, when the peaches are moved to a high-temperature environment for ripening, the flesh becomes dry, mealy, and soft, and the flesh around the pit clearly
