Key Technical Points for Overwintering Management of Shiitake Mushroom Bags
After the Winter Solstice arrives, temperatures will drop noticeably. Regarding how to do a good job of overwintering management for shiitake mushrooms, the following technical suggestions are hereby put forward for mushroom growers' reference: 1. Remove the shade net originally used for cooling and heat insulation so that sunlight shines directly onto the plastic greenhouse, thereby raising the daytime temperature inside the greenhouse. 2. Reduce the number of ventilation times around the greenhouse, exchanging the air once every other day. For the small arched film inside the greenhouse, apart from when picking shiitake mushrooms, there is generally no need to lift the film for ventilation. After one flush of mushrooms is finished, let the mushroom bags dry and ventilate for 7-10 days, then inject water to stimulate pinning. During the pinning stimulation period, pay attention to heat preservation. Inside the mushroom shed

Introduction to the specific method of soil-covering cultivation of shiitake mushrooms
First, soil-covering cultivation of shiitake mushrooms adopts techniques such as natural color change, open fruiting, widening the wet-dry difference, and water management with alternating wet and dry conditions, which can make the shiitake fruiting bodies large, the flesh thick, and the number of flower shiitake abundant. Second, compared with the conventional method, the yield can be increased by 30%-40%. Third, after the substrate sticks are removed from the bags and covered with soil, they can change color naturally and are not easily infected. Fourth, after the substrate sticks are covered with soil, they can fully utilize and absorb the water and nutrients in the soil, which can save the cumbersome procedure of soaking the substrate sticks to replenish water after each flush of mushrooms. The specific method is as follows: bed width 80-100 cm, depth 20 cm

Rare Large Stand of Endangered Natural Yew Trees Discovered in Zhashui, Shaanxi
A rare large stand of natural yew trees, numbering more than 100,000, has recently been discovered in Zhashui County, Shaanxi, which is located in the Qinling Mountains. Some experts say that the yew is an endangered tree species preserved from the Quaternary glacial period, and that the extensive area and large number of this natural yew forest are rare. It is understood that Zhashui is located on the southern slope of the Qinling Mountains, in the transitional zone between the subtropical and warm temperate zones, with abundant rainfall and a forest coverage rate of 78 percent. It is rich in plant resources and has been known since ancient times as a "natural medicine storehouse." In Dongyuan Gully, Fenghuang Town, a yew was once found with a trunk circumference of 2.18 m, a canopy covering half a mu of land, and an age of more than 1,900 years.

Key Technical Points for Shiitake Mushroom Harvesting and Mycelium Recovery Management
Harvesting and Mycelium Recovery Management After the shiitake fruiting bodies form, it is essential to judge their maturity so they can be harvested in time. Mushrooms that are large, with round caps and straight stipes are harvested as fresh-market mushrooms, and they must be harvested promptly when the cap is about to open. Flower shiitake and vegetable shiitake are harvested when the partial veil has just split. Pay attention to the harvesting method: when picking, hold the mushroom bag with the left hand, and with the right thumb and index finger pinch the base of the flower shiitake stipe firmly, first twist left and right, then gently pull upward, and do not let the stipe base remain on the mushroom bag, so that the stipe base does not rot on the bag and affect later fruiting. If the base is deep, a small knife can be used from the stipe base

Key Technical Points for Over-summering Management of Spring Bag-cultivated Shiitake Mushrooms
After the color change of spring bag-cultivated shiitake mushrooms is completed in mid-June, the high-temperature season begins. Shiitake mycelium is intolerant of high temperatures and drought; when the temperature exceeds 35°C and persists for 4 hours, the mycelium begins to die, or even self-lyse. The following are the key technical points for ensuring that mushroom bags safely over-summer in production, for the reference of mushroom growers: 1. Cooling. Use shade, ventilation, sprinkling water on the ground, hanging clean wet burlap pieces and other methods to lower the temperature, so that the substrate temperature does not exceed 30°C. On sunny summer days, close doors and windows from 9 o'clock until sunset to prevent hot air from entering the room. 2. Shading. Thicken the shading

Eight preventive measures for bagged shiitake mushrooms to safely overwinter the summer, explained in detail
Based on our investigation and analysis of the summer-survival problems in large-scale bagged shiitake mushroom cultivation in Xixia over more than ten years, we have summarized a set of preventive measures for bagged shiitake mushrooms to safely get through the summer. They are presented below for reference. 1. Prevent contaminated spawn. There are many factors that can cause contamination in spawn, for example: incomplete sterilization of the substrate, lax disinfection during inoculation, introduction of pathogens during inoculation operations, air forced in through the cotton plug, respiration or damage during spawn transport, inoculation with contaminated spawn, and other such reasons. If contaminated spawn is used for production, it can harbor incalculable losses. 1.1

Overwintering edible fungi: raise the temperature and maintain humidity
December is the busiest period for edible fungus production. Most cultivated varieties are fruiting, some that fruit in spring are in the mycelial growth phase, and some spawn is being made or is in the mycelial growth phase. With the arrival of December, temperatures drop, which is a considerable challenge for edible fungus growth. Therefore, mushroom growers must plan reasonably, manage well, and ensure normal growth of the edible fungi. Oyster mushrooms are mostly at the fruiting stage, and some cultivated in autumn have entered the tail end of fruiting. The focus of management is heat preservation, resolving the contradiction between raising the temperature and maintaining humidity in the mushroom shed and ventilation.

How do potted miniature chrysanthemums overwinter? Master these overwintering methods
1. Soil burial, or burying the lower part in soil while covering the upper part with dry leaves. Before the frost season arrives, potted miniature chrysanthemums can be kept in their pots or removed from them, and for the burial covering use plain wet soil. First, it is forbidden to use fertilized soil or soil mixed with firewood, grass or leaves, because plain soil will not mold or generate heat that harms the chrysanthemum roots and plants. If the lower part is buried in plain wet soil and the upper part is then covered with dry leaves, even if the leaves become wet from snow they will dry out in the wind after sunny weather, and will not cause great harm to the chrysanthemum plants. Second, it is forbidden to keep watering after burying, because they are already buried in wet soil, and the miniature chrysanthemums lie dormant under the soil, neither growing nor consuming water,

Emergency supplementary fertilization for cotton to promote plant recovery and regrowth
Yang Xiushen, a researcher at the Industrial Crops Research Institute of the Provincial Academy of Agricultural Sciences, said that since July, our province has been repeatedly hit by torrential rains, and the flooding has caused widespread inundation of farmland, inflicting severe damage on cotton. Draining water and reducing waterlogging, and emergency supplementary fertilization to promote recovery are the critical priorities of the current disaster relief and remediation effort. At the same time, weeds must be removed promptly, the soil loosened, and earth hilled up around the roots, and replanting and supplemental planting should be carried out according to the conditions of each field. Emergency removal of standing water in the fields must seize the time and adopt all necessary and possible means to quickly drain the standing water, reduce the impact of waterlogging on cotton growth and development, and lower the mortality rate of cotton seedlings. For low-lying areas, especially secondary
