Korla Fragrant Pear Open-Center Training Technique and Cultivation Key Points
In order to continuously raise the level of orchard industry development, the "dwarf, dense, early, high-yield" cultivation technique should be adhered to in fragrant pear orchard management, and management should follow the six-character policy of "slow, drop, control, promote, cut, even." 1. Conditions and methods for open-center reshaping. 1. Fragrant pear trees over 25 years old are basically the traditional three-main-branch delayed open-center form, and the tree form has already set. If the tree form is complete, the three or four main branches at the base are sound, and the canopy has already filled the space, the central leader can be directly dropped for open-center; if the lower main branches are incomplete, with only 1~

What causes mushrooms to have a thin cap skin and open their caps prematurely?
Symptoms: The fruiting bodies have thin stems and thin caps, and open their caps prematurely. Causes: Excessive mushrooming density, too high a temperature in the mushroom house, insufficient relative air humidity, overly dry casing soil on the bed surface, and rapid growth of the fruiting bodies can all lead to a thin cap skin and premature cap opening. Preventive measures: Appropriately control the mushrooming sites, ventilate the mushroom house in the early morning and evening, lower the temperature in the mushroom house, and appropriately increase the moisture of the casing soil on the bed surface and the relative air humidity.

What are the key techniques for open-field cultivation of spring potatoes?
Potatoes are nutritious, high-yielding, easy to store, and have a long market period. They can be used as both a vegetable and a staple food, and are deeply loved by consumers. Open-field cultivation of potatoes in spring is the most common cultivation method, and almost every farming household plants them. To achieve high quality and high yield in open-field spring potatoes, the first step is to select good varieties. Potato seed potatoes must be original seed of varieties such as "Dongnong 303" and "Kexin No. 4" introduced from the north. Do not use self-saved seed, and even more so, do not use local seed that has been planted for many years, has an aging variety, and seriously degraded seed characteristics. "Dongnong 303" and "Kexin No. 4" have shown high quality, high yield, and early maturity after years of

Detailed Explanation of Key Techniques for High-Yield Open-Field Mushroom Cultivation
Many factors affect the yield and quality of open-field mushroom cultivation. From years of production practice, we have found that in the path to achieving high-yield and high-quality open-field mushroom cultivation, spawn selection, compost heap building, bed preparation and spawning, field management, and integrated pest and disease control are five key links. We hereby summarize our research on the key techniques of these five links as follows, in the hope of being of some benefit to cultivators. I. Spawn Selection Strains obtained through tissue isolation or other means must undergo fruiting tests before they can be used on a large scale.

Prevention methods for thin-skinned mushrooms that open their caps early
Because the temperature alternates between cold and hot, the temperature varies greatly, and the day-night temperature difference reaches 10-15°C. When the mushroom house is ventilated excessively, or the temperature remains above 18°C for a long time, causing the mycelium to grow quickly and the mushrooms to fruit too densely, the fruiting bodies are prone to developing thin-skinned, cap-opening mushrooms with slender stipes, thin caps and early cap opening. Preventive measures: scientific management. Ventilate and spray water in appropriate amounts; when the weather changes suddenly, strengthen management and maintain suitable temperature and humidity in the mushroom house; during fruiting, the humidity should be kept at 12-16°C, and excessively dense mushroom buds should be removed appropriately.

For open-field cultivation of potatoes in the autumn crop, whole-tuber sowing should be adopted.
Since the sowing period for open-field potatoes in the autumn crop falls in August, which is hot and rainy, sowing after cutting the potatoes into pieces leads to serious problems such as tuber rot and dead vines. Therefore, whole-tuber sowing should be adopted for open-field potatoes in the autumn crop. When using whole-tuber sowing, select potatoes that are unbruised, disease-free, crack-free, with bright skin color and a moderate size. Because whole-tuber sowing of potatoes emerges more slowly than cut-piece sowing, and because potatoes harvested in spring are used as seed, the seed tubers are still in a dormant state at autumn sowing (except for some varieties with an extremely short dormancy period, such as Fengshoubai and Zheng

Detailed Explanation of Key Points of New Open-Air Cultivation Techniques for Straw Mushrooms
For cultivating straw mushrooms, mainly rice straw is used. Materials with higher plant cellulose content such as bagasse and corn stalks can also be used. Because straw mushrooms have many sources of cultivation material, the cost is relatively low, and the cultivation technique is relatively simple, with very high economic returns. For every 100 kg of rice straw, from inoculation to fruiting takes only 12 days, and the entire production cycle is no more than one month, yielding 20-30 kg of fresh mushrooms. In this way, every 100 kg of cultivation material can create an output value of 60-120 yuan. The straw mushroom is a fungus that likes high temperature and high humidity. The temperature required for mycelial growth is 20
