Key technical points for winter management of tea plants to help tea gardens overwinter safely
1. Carry out the garden-closing work by spraying the whole tea plant with 0.4-0.5 degrees Baumé lime-sulfur mixture. 2. Apply 150 kg of decomposed cake fertilizer in holes or furrows, or 100 kg of special compound fertilizer for tea, and finish applying the base fertilizer by November. 3. In conjunction with fertilization, clear weeds inside and around the garden to reduce overwintering habitats for pests. 4. For expanding tea gardens, select good varieties, deeply plow furrows in the tea garden, apply base fertilizer deeply, adopt double-row single-plant planting, low-hole cultivation, and low-position pruning, and strive to complete planting in this winter and next spring.

How to prevent and control contaminants in oyster mushroom cultivation? Covering with burnt mud ash is effective
Bed-style cultivation of oyster mushrooms: When bed-style cultivating oyster mushrooms, if contaminants appear sporadically on the surface of the substrate, they can be eliminated by smearing or covering the affected spots with thick quicklime slurry; if contaminants appear in large amounts on the substrate surface, cover the contaminated part with 2-3 cm thick burnt mud ash, making the covered area larger than the contaminated area, and pat it slightly firm to eliminate the contaminants; if contaminant contamination on the substrate surface is severe, cover the entire substrate surface with burnt mud ash and pat it firm, and after a few days the mycelium will resume normal growth. Bag-cultivated oyster mushrooms: first pick out the bags contaminated by unwanted organisms, then in a place with relatively high

What to do when oyster mushrooms grow contaminant fungi? Covering with mud and sand can prevent and control it
Contaminant fungal infections often occur during oyster mushroom cultivation, and are especially severe in hot seasons, causing reduced yields in mild cases and total crop loss in severe cases. Most of these contaminant fungi are aerobic and tolerant of high temperatures and high humidity. Covering with mud and sand can prevent and control them. The specific techniques are introduced below: 1. Prevention and control of contaminant fungi in bed-cultivated oyster mushrooms. When contaminant fungal contamination appears in large-bed oyster mushroom cultivation, the cause of contamination should first be identified. Common causes include sudden high temperatures, water entering the substrate, unclean surrounding environment, insect pests, etc. Based on the specific situation, remove the source of contamination, then treat the contaminated oyster mushrooms as follows: if contaminant fungi appear sporadically on the substrate surface, smear or cover the affected area with thick lime slurry. When a large amount of contaminant fungi appears, dig up mud and sand from more than 30 cm below the ground surface, crush it, add 2% lime powder and mix thoroughly, remove the plastic film, and cover the contaminated part of the substrate surface with the lime-mixed mud and sand to a thickness of 2-3 cm. The covered area should be slightly larger than the contaminated area, and the mud and sand should be patted slightly firm. When the substrate surface is severely contaminated, the entire bed surface should be covered with mud and sand, then covered with a plastic film that has been washed clean with disinfectant solution, and routine management should be resumed. After a few days, the mycelium will resume growth.

Spring management of garlic after overgrowth must start early
For garlic sown in autumn 2006, temperatures from planting through early December remained higher than in previous years, which accelerated the growth of the garlic sprouts. Before winter, the garlic grew to 7-10 leaves (the optimal seedling age for overwintering is 5-7 leaves), showing overgrowth, and had already begun "mother bulb rot," with pest problems occurring. As a result of overly rapid growth, the garlic suffered from poor nutrient accumulation, reduced stress resistance, slow greening after the New Year, severe disease, and reduced high-yield potential. In spring, garlic must complete a series of growth processes including greening, vigorous seedling growth, garlic scape elongation, and bulb enlargement. On the basis of applying sufficient base fertilizer, garlic in spring

How to train a dog to roll over: methods and detailed steps
If the dog has already learned the two commands "down" and "stay," then teaching it to roll over is very easy. Have it lie down, then command it: "Roll over!" While giving the command, grasp its chest and roll it from one side to the other to express your meaning. During the initial practice, do it several more times, and stop using your hand to help it roll as soon as possible. When it is begging for something, it will pay attention to your fingers, its eyes fixed on the food in your hand. Hold the hand with the food higher than its nose, curve your hand into an arch, and move it from the left, past its body to the ground, and then

How to safely overwinter shiitake mushrooms through summer? These management points must be mastered
The quality of summer management for shiitake mushrooms directly affects yield and profitability. Doing a good job of summer management is a key step in shiitake mushroom production, and two methods can be used: indoor and outdoor. I. Indoor spawn running for summer survival (1) Minimize the number of shiitake bags indoors and the number of bag layers. Stack two bags in a cross pattern, with no more than 5 layers at most, and keep the spacing between stacks at more than 20 cm to facilitate ventilation and heat dissipation. (2) Build a shade canopy outside the window so that sunlight does not shine directly onto the window or indoors. (3) In hot weather, close doors and windows at 7 a.m. to prevent outside hot air from entering indoors, and in the evening

Control Recommendations for the Overwintering Generation of the Box Tree Pyralid Moth
The box tree pyralid moth (Glyphodes perspectalis) is one of the important leaf-eating pests of forestry plants in this district, mainly damaging Chinese box (Buxus sinica var. parvifolia) and Japanese box (Buxus bodinieri). Since early spring this year, the whole district has carried out 2-3 rounds of comprehensive control against this pest, effectively bringing the damage under control; however, since the damage period of this pest is long and can last until the end of October, continued follow-up monitoring of this pest is still needed. According to monitoring at two sites, the Anting Ginkgo Garden and the Fangtai Flowers and Plants Horticultural Farm, a moth peak appeared under the forecasting lamp in early to mid-September, with the highest moth numbers on September 7-9, averaging 22.3 moths per lamp per day

Feeding and management methods for autumn lambs to safely overwinter
Sheep estrus and mating occur mainly in spring and autumn, and the gestation period averages around 150 days, so spring and autumn are also the seasons when lambing is more concentrated. According to surveys, the overwintering survival rate of autumn lambs born in various places is significantly lower than that of spring lambs. The main reasons: 1. Environment. When autumn lambs overwinter, they are in the suckling period or weaning period. In winter, green fodder is scarce, forage quality is poor, ewes' milk is insufficient, and lambs are malnourished, weak in constitution, and poor in disease resistance. Moreover, the long dry and cold winter climate very easily causes respiratory infections in lambs, and many lambs die from pneumonia infection. Due to the cold climate

Detailed Explanation of Technical Measures for Safely Overwintering Shiitake Mushroom Logs Through Summer
Key Management Points for Safely Overwintering Mushroom Logs Through Summer. Outdoor summering. Outdoor shade shelters have good ventilation and cool down quickly, therefore, using outdoor shade shelters for mycelium running can effectively reduce the occurrence of "mushroom burning." Specific measures taken for summering and mycelium running using outdoor shade shelters: First, build trellises around the shade shelter and plant vine crops such as pumpkins and luffa to improve the shading effect; Second, install automatic rotating tap water sprinklers or spray pipes on the shelter roof, and spray water to cool down from 10 AM to 4 PM every day; Third, dig interconnected trenches 20 cm wide and 30 cm deep around the inside of the shelter and on both sides of the walkways, and run flowing water through the trenches to cool down.
