In the winter in northern China, it is cold. For the south seedlings to transfer seedlings, new transplanted seedlings, and two-year-old plants for open cultivation, cold-tolerant perennial flowers must be protected against cold to avoid cold damage. According to the author's many years of work experience, we now introduce some common cold measures for seedlings in northern China. First, according to local conditions and suitable trees: According to local climate conditions, planting cold-resistant trees, flowers. Second, to strengthen the cultivation and management, and enhance the ability of seedlings to resist cold: through rational irrigation of seedlings, scientific fertilization (such as less nitrogen in autumn, controlling seedlings and appetite) and other measures to promote the growth of seedlings robust and enhance their own ability to resist cold. Third, seal water and turn back to the Qingshui: in the soil before the freezing of water once the frozen, the soil contains more water, the surface temperature of the winter will not fall too low, too fast, the spring surface temperature rise is also slow. Casting back to Qingshui is generally carried out in early spring. Due to the large temperature difference between early and late nights, timely pouring back to Qingshui can reduce the temperature difference between day and night at the surface and prevent the spring cold from harming plant roots. Fourth, wind barriers: for newly planted or introduced tree species, there is a wind barrier on the main wind side or the periphery of the plant to prevent cold, some species need to be covered with straw curtain (such as the southern species of North Euonymus japonicus), Generally 1-2 years to adapt. 5. Trunk Protection: The trunk is often wrapped and painted white. 1. Trunk wrap: Mostly before winter, the trunk of newly planted trees or cold-tolerant species is wrapped or wrapped with straw ropes or sacks, and the height may be about 1.5 to 2 meters. 2 trunk white: generally in the autumn, with lime and salt or lime sulfur on the trunk of the white, the use of white reflection of sunlight, reduce the absorption of solar radiation heat of the trunk, so as to reduce the day and night temperature difference between the trunk, to prevent bark freeze. In addition, this method also has a certain effect on the prevention of pests. 6. Coverage: It is mostly used for flowers in open fields. Before frost, it covers hay, straw mats, and horse dung on the ground. This method is both economical and effective, and its application is extremely common. It can also cover plastic films and other materials, but it needs certain economic conditions. Seven, smoke method: often used in open garden flowers, usually in the sunny night, light grass, the use of smoke to reduce soil heat loss, the use of this method is not obvious when the temperature is too low, but also cause some pollution to the environment, Therefore, such cold protection measures should be avoided as far as possible near the urban areas. VIII. Soil protection against the cold: For some perennial flowers or flower shrubs, after pouring frozen water, a 30-40 cm high earth mound is piled around its rhizome (mound to be photographed).
Porcelain Bottle Yellow Rice Wine
Porcelain Yellow Rice Wine is a type of Chinese rice wine made from glutinous rice and yellow yeast. It is a traditional drink in southern China, particularly in Zhejiang and Guangdong provinces. The wine is named after its distinct yellow color, which comes from the use of yellow yeast in the fermentation process. Porcelain Yellow Rice Wine has a sweet and fruity taste with a mild alcohol content, typically around 14-15%. It is often served as an aperitif or used in cooking to add flavor to dishes.
