How to protect walnut trees from the cold? A detailed guide to cold-protection techniques for walnut cultivation
Because walnut tree branches have a large pith and high water content and poor cold resistance, they are prone to freeze damage in the colder and drier areas of the north, causing branch dieback. Therefore, to ensure the normal growth of young trees and prevent freeze damage, winter cold-protection work should be strengthened to reduce the harm

Cultivation Methods for Loquat in Greenhouses in Northern China
Loquat is rich in nutrients and has a unique flavor; its flowers, fruit, leaves and roots can all be used medicinally, but it does not store or transport well, and it is a specialty fruit tree of southern China. At present, the Institute of Forestry and Pomology of the Beijing Academy of Agriculture and Forestry Sciences has introduced the early-maturing loquat variety Zaozhong No. 6 and cultivated it in a greenhouse, avoiding the low temperatures of Beijing's winter

Key Points of Bee Pollination Technology in Strawberry Cultivation
Greenhouse strawberry cultivation takes place in winter and early spring, when temperatures are low, humidity is low, daylight is short, and insects are few. This affects anther dehiscence and pollen dispersal, leading to poor pollination and the easy development of various deformed fruits, seriously affecting yield and quality. To create good pollination conditions, besides paying attention to ventilation

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

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

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
