How to manage greenhouse strawberries in windy, snowy and foggy weather?
In protected cultivation of strawberries, severe weather such as strong winds, heavy snow and dense fog is often encountered in winter and spring. Although these weather conditions occur at a low frequency, once they occur, if measures are not taken in time, strawberry production will suffer serious losses. The management experience from production is now presented

Detailed Explanation of Key Points for Spring Planting and Management of Yue Jiao Chili Pepper
Yue Jiao chili pepper can be sown in spring and autumn in South China. Spring sowing can be carried out from December to January of the following year. Before sowing, disinfect the seedbed soil with carbendazim; after sowing, control the seedbed soil moisture, keeping the soil half-dry and half-moist. When the weather is clear and sunny, remove the film in time for ventilation. Transplanting can be done in March. Plant spacing

Key Management Techniques After Top Grafting and Replanting of Lychee
After top grafting of lychee, sun protection and ant prevention work must be done well, and new shoots on the original rootstock and water-drawing branches should be removed promptly and regularly so that nutrients are concentrated in the scion, facilitating the sprouting of new shoots and growth and development. After the graft has survived, cut off the water-drawing branches in stages and batches. After the first flush of shoots has completely turned green, cut off part of the water-drawing branches; after the second flush of shoots has fully matured, cut off part of the water-drawing branches; in the spring and summer of the second year after grafting, cut off all water-drawing branches.

Detailed Explanation of Key Technical Points for High-Yield Raspberry Cultivation and Management
Raspberries have very strong adaptability. In our country, except for the Qinghai-Tibet Plateau, they can be planted in most areas. In the north, raspberries can endure low temperatures of -40 to -45°C, and they can be planted anywhere in the south. In subtropical regions certain changes will occur, because raspberry roots do not have natural dormancy; when their symbiotic conditions are met, they will grow year-round without shedding leaves. They can bear fruit twice a year, but the fruit shape is slightly smaller than fruit from the north, while the yield is higher than in the north. There are many raspberry varieties, with more than 400 in the world. In terms of fruit shape, there are red, black, yellow, purple and other colors. Fruit weight is generally 5-10 grams, with the largest reaching 20 grams. Raspberry yield is 1000-1500 kg per 667 sq m.</p><p></p><p>Orchard Establishment and Planting </p><p>Raspberries can be planted in spring or autumn. Spring planting is after the soil thaws and before the seedlings sprout (March-April), while autumn planting is preferably after the seedlings have lignified and before the soil freezes (October-November). For field planting of raspberries, the row spacing is 2.5 m and the plant spacing is 0.8 m, with 2-3 plants per hole, 660-990 plants per 667 sq m. Before planting, soak the seedling roots in water for 12-24 hours to ensure the seedlings have sufficient moisture in their bodies. At planting time, the seedling roots should be 15 cm from the ground, and the area around the seedlings should be 30 cm. When covering with soil, compact the soil, and it is best that the soil does not exceed the seedling soil mark. Water thoroughly once.</p><p>Trellising and Guiding Branches </p><p>When branches grow to 1.5 m, trellising and branch guiding must be carried out. Within the row, set a post every 5-10 m, 1.5 m high, and stretch two wire lines. The upper wire is fixed at the top of the posts, and the lower wire is 1 m above the ground. Guide the branches onto the wire lines in a fan shape and tie them well.</p><p>Pruning </p><p>Pruning is divided into three times. The first pruning is at planting time. After the seedlings survive, excessively dense, thin and weak branches and damaged branches should be cut off flush with the ground. When the new shoots of the year grow to 40-60 cm, for plants with relatively low density, pinch the tips at 10 cm to promote the sprouting of new side branches and increase the number of branches. The second is pruning of basal shoots (that is, the new shoots of the year). It is advisable to leave basal shoots cut back to 1.3-1.5 m; those exceeding 1.5 m should be pruned. For each plant cluster, select and retain 6-8 vigorous basal shoots and cut off the rest. The third pruning is after fruit harvesting is finished, when the fruiting canes should be cut off flush with the ground.</p><p>Fertilizer and Water Management </p><p>Base fertilizer should preferably be applied in early autumn, mainly with decomposed farmyard manure, and an appropriate amount of chemical fertilizer may also be added. Apply the base fertilizer mixed with soil on one side 40-60 cm from the plant. When applying chemical fertilizer, the soil must have sufficient moisture. Apply about 0.5 kg of compound fertilizer on one side 50 cm from the plant. Raspberry is a shallow-rooted plant. When watering during drought, it is enough for soil moisture to reach 40 cm; the principle is that it can be watered in drought and drained in waterlogging. In weak areas, water once with winter protection water before winter. In arid areas, some leaves, chopped straw and the like can be spread around the raspberries, which can prevent water evaporation and also increase soil fertility.</p><p>Intertillage and Weeding </p><p>Raspberries can be intertilled and weeded twice each year. For chemical weeding, acetochlor, glyphosate, simazine, linuron and other chemical herbicides can be used (use according to the instructions). In order to improve land utilization, some low-growing plants, such as beans and potatoes, can be planted between the fruit trees.</p><p>Raspberry fruits can be picked and marketed when they are 90% ripe; for industrial deep processing, they must be harvested only when fully ripe.</p>

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.

Key Technical Points for Early Spring Management of Greenhouse Chives
1. Temperature management. Chives prefer cool conditions, with an optimum growing temperature of 15-24°C, and ventilation should be provided appropriately during the day. To promote sprouting, after the shed is covered the daytime room temperature should be kept at 18-25°C; after sprouting, the daytime room temperature should be controlled at 17-23°C. Before the first cutting of chives is harvested, the daytime temperature should be 15-2

Management Methods and Technical Key Points for Growing Chinese Toon in a Greenhouse
Chinese toon (Toona sinensis) is a woody vegetable, and its tender leaves are edible. Only when the average temperature over a ten-day period reaches 15°C do the young buds begin to sprout and unfold new leaves. Therefore, open-field Chinese toon in the central part of our province has a harvest period in mid-April. Greenhouse production of Chinese toon involves moving the stems of 1- to 2-year-old Chinese toon that have already dropped their leaves into
