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

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.

How to control the grape clearwing moth? Timely prevention and control is needed when growing grapes
In recent years, the grape clearwing moth has occurred in many vineyards and courtyard grapes in Xuzhou, mainly damaging grape vines, causing reduced yields and even the death of entire plants. The grape clearwing moth damages young grape shoots and 1-2 year old vines with its larvae. The young larvae bore into the tender shoots and feed on the pith, causing

Grasp the Three Key Points in Gastrodia elata Cultivation to Achieve High Yield
I. Armillaria must have "three new" aspects. 1. New technology: new methods to obtain new strains. The new method uses the latest biotechnology to detoxify the strains, which is by far the most advanced method of obtaining strains. Among traditional Armillaria strains, the best results come from tissue

Detailed Explanation of the Key Points of Shaping and Pruning Techniques for Goji Berry Cultivation
For goji berries to yield abundantly, they must first be trained into a good tree form. Goji berries have strong branching ability and vigorous growth, and have the characteristic of flowering and fruiting twice each year. If management is poor and shaping and pruning are improper, not only will the yield of the current year be affected, but the tree vigor will also decline prematurely. Therefore, proper

Strictly guard against diseases when introducing sweet potato
At present, sweet potato cultivation in our province is expanding into non-traditional growing areas. In these areas, sweet potato storage and seed preservation techniques are not up to standard, and when the storage pits are opened in spring, the tubers are severely rotten, so the supply of seed potatoes cannot be guaranteed. Some sweet potato farmers have to introduce seed from other places, which increases costs. Because farmers lack knowledge about

Three key stages to grasp in rice film seedling raising
Based on many years of practical experience, I believe that three key stages should be noted in the technique of raising rice seedlings under film: the closed stage, the hardening stage and the film-removal stage. The first stage: the closed stage, that is, from sowing to the one-leaf-one-heart stage. During this period the film must be tightly closed to create

To grow peanuts well, management at the middle and late stages is key
In peanut planting and production, if middle and late stage management cannot keep up, it will lead to lower peanut yields, which is a factor that seriously restricts the expansion of peanut planting area. 1. Timely topdressing and hilling. From the beginning of flowering to full flowering, a lack of fertilizer in peanuts easily reduces the number of flowers and affects peg penetration into the soil for pod setting
