After spring tea harvesting, attention should be paid to summer management of the tea garden.
After spring tea harvesting is finished, summer tea garden management work should be done promptly. 1. Fertilize in time. Apply 15-20 kg of urea per mu, or 25 kg of Zhongcha No. 1 fertilizer. Do not apply compound fertilizer with a high proportion of phosphorus and potassium, otherwise it will accelerate the reproductive growth of tea plants. During midsummer, carry out foliar topdressing. 2. Cultivate and weed. After June, apply chemical weed control once every 25 days. Commonly used herbicides include 10% glyphosate and 25% paraquat aqueous solution, etc. In July, deep-plow the tea garden once, which can both

How to carry out early-stage spring tea management? A detailed explanation of nine steps
Spring tea is the tea crop with the highest yield and the best quality of the year, fetching high prices and delivering good economic returns. Practice has proven that doing a good job of early-stage spring tea management plays a major role in increasing spring tea yield and improving spring tea quality and profitability. Therefore, it is essential to promptly complete tea garden management before the Spring Festival. 1. Apply additional and early topdressing. The time for applying the bud-forcing fertilizer is generally 15-30 days before the tea plant buds break, that is, before the end of February, applying 25-30 kg of urea per mu or 50-60 kg of ammonium bicarbonate or 50 kg of special compound fertilizer for tea plants.

Ten early technical measures for spring tea management
Good spring tea management is the key to ensuring a bumper tea harvest throughout the year. Practice has proven that applying the "ten early" techniques in spring tea management gives very good results. 1. Apply base fertilizer early. Apply base fertilizer early after the tea season ends to replenish the nutrients consumed by that year's tea growth, so that the tea plants have sufficient nutrient reserves, while also strengthening the tea plants' activity in autumn and winter, enhancing their photosynthetic capacity and improving their cold resistance through the winter, which helps the next year's spring tea sprout early and grow vigorously. Base fertilizer should be applied before the autumn equinox, when the root rapid-growth period arrives, and no later than the end of September. Organic fertilizer should be the main type; for mature

Key Management Techniques for Log-Cultivated Ganoderma in Summer
1. Thinning: About 10-20 days after the mature colonized logs are covered with soil, primordia begin to form. Because the light in artificial shade sheds is generally quite strong, the cut cross-sections of the logs are stimulated by light and tend to form numerous primordia. To improve the quality of the Ganoderma, excess primordia should be removed, leaving only 1-2 thick, sturdy primordia per log segment. If two primordia are kept, they should be more than 15 cm apart. Otherwise, after the caps differentiate, they will crowd and stick together, causing deformities and reducing commercial value. Thinning can be done by simply picking them off by hand, then covering the spot with fine soil.

Detailed Explanation of Key Management Techniques for Mushroom Fruiting
For mushroom production in October, the focus should be on mycelium colonization management. For those currently fruiting or about to fruit, management should be carried out promptly to ensure ideal fruiting. Early-autumn oyster mushrooms begin fruiting in early September, and by October most have completed 2 flushes, with some in the midst of managing a 3rd flush. Even those fruiting in mid-to-late September have at least 1 flush brought to market, and by October should enter 2nd-flush management. The management focus at this stage should emphasize one word: “water”. For conventional cultivation,

Detailed Explanation of Key Management Techniques for Picea koraiensis Seedlings
(1) Shading: Picea koraiensis seedlings prefer shade and humidity. After the seedlings emerge, appropriate shading yields a survival rate 30%-40% higher than full-light seedling cultivation, with a 32% increase in seedling height and tender leaves that are bright green. Generally, when 50% of the seedlings have emerged, begin erecting daily shade curtains for shading, until they are removed in early to mid-July. If covering materials are difficult to obtain, tall-stem crops (such as corn) can be planted along the bed edges to replace reed curtains. In some areas with sufficient water sources and convenient irrigation, watering 2 to 4 times daily in small amounts but frequently, with timely and appropriate watering, can also make full-light seedling cultivation successful. (2) Topdressing

Detailed Guide to the Management and Propagation Techniques of Dawn Redwood
The dawn redwood favours a warm and humid climate, with cool summers, and winters with snow but not severe cold. The average annual temperature is 13°C, the extreme minimum temperature is -8°C, the extreme maximum temperature is 35.4°C, and the frost-free period is 230 days; the annual precipitation is 1500 mm, and the average annual relative humidity is 82%. The soil is acidic mountain yellow earth, purple soil or alluvial soil, with a pH value of 4.5--5.5. It mostly grows in valleys or near the foot of mountains, in places with gentle terrain, deep soil layers, and moist or slightly waterlogged conditions. It has strong cold resistance and strong resistance to waterlogging, and can grow in lightly saline-alkaline land.

Detailed Explanation of Rhododendron Tissue Culture and Cultivation Management Techniques
As a high-grade ornamental flower, rhododendron is not easy to propagate and grow in North China. This is mainly because most of the soil in North China is alkaline, while rhododendrons prefer typical acidic soil, thus making propagation and planting somewhat difficult, and they can only be grown as greenhouse flowers. Rhododendron propagation methods include seed sowing, cuttings, layering and grafting, and tissue culture. Tissue culture does not require seeds; it only needs the stem tips of the current year's branches of the rhododendron. In a very short time, a large number of small rhododendron seedlings can be cultured in test tubes, and it is not restricted by season.

Management methods and technical key points after rhododendrons bloom
Pruning and shaping: after rhododendrons finish blooming, the spent flowers generally need to be removed by hand, followed by appropriate thinning of branches, cutting away overly dense branches, and letting them send out new growth. Fertilizer and water management: in northern regions, water is on the alkaline side and relatively hard, and watering plants with it over the long term can easily cause soil alkalization, affecting flower growth. Therefore, before watering, the water should be stored in a container for more than 24 hours and used after the chlorine has evaporated. Alternatively, water mixed with an appropriate amount of ferrous sulfate or edible white vinegar can be applied about once every 10 days. Rhododendrons do not need much fertilizer, and it is generally applied along with watering. You can

How to grow azaleas? A full breakdown of cultivation and management key points
(1) Potting and repotting: Use yellow mud + leaf mold as the main components, mix in a little river sand as the growing medium, ensure the soil is on the acidic side, and avoid heavy clay soil. When first potting, choose as small a pot as possible, then gradually move to larger pots; azaleas do not need repotting every year, and repotting and soil replacement should only be considered when the roots have filled the pot and water no longer drains out easily. (2) Cutting propagation: The plum rain season is the best time for cuttings, when the new azalea shoots are already semi-lignified and the temperature and humidity are suitable, which is very favorable for the rooting and survival of the cuttings. Take healthy new shoots about 5-7 cm long, remove the lower leaves, keep 3-4 top leaves, and use mountain soil mixed with yellow sand as the base
