How should pepper seedlings be managed in a warm winter climate?
In recent years, with global climate warming, winter temperatures have been getting higher and higher. In Yongzhou City, during the past winter and this spring, there were several periods with temperatures higher than the same period in previous years. Such continuously high temperatures caused excessive vegetative growth of pepper seedlings, bringing great difficulties to cultivating strong seedlings.

Summary of Winter Field Cultivation and Management Experience for Peppers
Management before and after seedling recovery: 1. Before seedling recovery, focus on heat preservation and moisture retention. To raise soil temperature, cover with plastic film promptly after planting. If no plastic film is used, carry out intertillage. After seedling recovery and before flowering, generally do not water; water lightly only during drought. Before the rows close,

In loquat cultivation, autumn and winter management is key
Loquat is a fruit that comes to market in spring in our province, with a high market price and good returns. Loquat generally blooms in autumn and winter, with a flowering period of about 90 days. Because flowering and fruiting consume a large amount of nutrients, and because it is prone to freezing damage in winter, strengthening autumn and winter management of loquat is the guarantee of obtaining high quality and high yield

Detailed Explanation of Key Techniques for Overwintering Onion Seedling Cultivation
I. Key Technical Points 1. The seedbed site must be land that has never been planted with onions; otherwise, the death rate of overwintering seedlings increases, which is unfavorable for preserving seedlings and increasing yield; 2. For greenhouse plots, the sowing period is August 1-5, sowing rate: 17 jin/mu of seed with a germination rate above 85%. For open-field seedling cultivation, the sowing period is August 5-10

How to do a good job of field management when growing peppers in winter
The winter planting season is about to kick off, and peppers are one of the main varieties grown. To achieve a high yield, field cultivation management must be strengthened. 1. Variety selection: It is advisable to choose varieties with strong plant growth, disease resistance and high yield. 2. Seed treatment and sowing: Generally, seeds are soaked in a chemical solution and raised in a seedbed. For soaking, use 3.5 ml of 0.01% Tianfengsu plus 15 g of 70% Hongri fungicide mixed with 7 kg of water, stir thoroughly, soak the seeds for 12 hours, then remove them for moisture-retaining germination. This can, on the one hand, increase the germination rate, strengthen seedlings and promote rooting, and can also disinfect the seeds and prevent seedling-stage diseases. An appropriate amount of chlorpyrifos can be applied to the seedbed to kill underground pests. The day before sowing, water thoroughly to saturate the soil and apply an appropriate amount of base fertilizer, then evenly broadcast the seeds on the seedbed. 3. Timely transplanting: 1. Land preparation, base fertilizer application, bed making: Peppers have a long growth period and weak roots. To promote the growth of branches and leaves and continuous flowering and fruiting, before transplanting, apply 5000 kg of high-quality farmyard manure and 15 kg of diammonium phosphate per mu in combination with land preparation. Make flat beds 1-1.5 m wide. 2. Transplanting: When the seedlings grow to about 10 cm, under suitable environmental conditions, they can be transplanted to the field. They can be planted at a row spacing of 1 chi x 1 chi, then water thoroughly to settle the roots. 4. Field management: 1. Management before and after seedling establishment: (1) Before seedling establishment, focus on heat and moisture retention. If there is no plastic film mulch, intertillage can be carried out. After seedling establishment and before flowering, generally do not water, and only water lightly during drought. Before the rows close, carry out hilling to protect the roots. Water after hilling, with the amount just enough to moisten the ridge surface. (2) Fertilization: When the first pepper fruit grows to 3 cm, apply fertilizer in combination with intertillage, with 200 g of decomposed dry manure powder and 10 kg of urea per mu. (3) Foliar topdressing: Use 3.5-7 ml of 0.01% Tianfengsu plus 1 liang of monopotassium phosphate mixed with 15 kg of water for foliar spraying, which helps enhance photosynthesis, promote deep root growth, promote robust plant growth, and at the same time enhance the plant's disease resistance. 2. Management during the flowering and fruiting period: (1) Use 3.5-7 ml of 0.01% Tianfeng plus 30 g of urea mixed with 15 kg of water, starting at the flowering stage, spray on the leaves once every 10 days to accelerate plant growth, promote continuous flowering and fruiting, increase the fruit-setting rate, prevent flower and fruit drop, and extend the harvest period. At the same time, improve pepper quality and reduce the occurrence of deformed fruits. (2) Water and topdress fertilizer in a timely manner. Topdressing should be done after each fruit harvest, and nitrogen, phosphorus and potassium should be used in combination to supplement the plant's nutrients. (3) Do a good job of pruning, removing side shoots, removing leaves and hilling: Cut off inner branches and old, diseased and disabled branches. Leave 2 leaves above the third-order branches and pinch off the tips. Remove old and diseased leaves from the lower part to reduce nutrient consumption. At the same time, hill up the soil once more to promote new root growth and prevent lodging. 3. Timely harvesting. When the fruit skin turns green, the fruit is relatively firm and the skin color is glossy, it can be harvested.

Intercropping Cultivation Technology for Watermelon and Chinese Yam in Large Arch Sheds
In early spring, using a large arch shed for intercropping watermelon with Chinese yam can bring the harvest and market time of both watermelon and Chinese yam more than 45 days earlier than open-field cultivation, thereby achieving relatively high economic benefits. 1. Arch shed structure. The shed is 7 m wide, the arch height at the center of the shed is 2.5 m, and the shed length depends on the plot.

Detailed Explanation of Key Technical Points for Overwintering Onion Seedlings by Heeling In
Before heeling in, first dig the seedlings out of the field (try not to damage the root system), shake them gently to shake off loose soil, and remove seedlings with no roots, no growing point, overly short, or thin and spindly ones, as well as leggy seedlings with overly long leaves, tillering seedlings, and pest- or disease-damaged seedlings, along with scallion seedlings (the leaf sheath part of scallion seedlings

What are the precautions for winter mulching of strawberries?
After late autumn, strawberries gradually enter dormancy. Strawberry roots are shallow and can tolerate low temperatures of -8°C and short periods of -10°C; if the temperature drops further, cold injury occurs, and in severe cases the plants die, causing a decline in economic returns. In northern cultivation, the main measure for overwintering cold protection of strawberries is
