For the southern seedlings to transfer seedlings, new transplanted seedlings, not tolerant to cold flowers, appropriate measures must be taken to avoid freezing damage during the cold winter season. First, pouring frozen water and returning green water before the soil is frozen once poured. After the soil contains more water, due to the large heat capacity of the water, the surface temperature of the surface layer will not fall too low or too fast during the winter, and the temperature of the surface layer will rise slowly after the spring. Casting back to Qingshui is generally conducted in early spring. Due to the large temperature difference between day and night in early spring, timely pouring back to Qingshui can make the surface temperature difference between day and night relatively reduced, to avoid spring cold endanger the seedling plant roots. Second, pack grass buried For small shrubs, should first remove the dead branches, old leaves, and then use the straw rope to bundle the branches scattered, and then surrounded by 6 to 8 cm thick straw and tightened, and finally around the ground around About 30 cm high mound buried, making real. For the open field flowers and trees, it is best to cover hay, straw mats, horse dung, etc. on the ground before the frost. This method is economical and effective. It can also be covered with plastic film and other insulation. Third, the common method to protect the trunk is wrapped in the trunk and painted white. Before and after entering the winter, the newly planted trees or the trunk of the cold-resistant seedlings will be wrapped or wrapped with straw ropes or sacks, and the height may be about 1.5 to 2 meters. Whitening the trees can prevent branch diseases and insect pests, but special attention should be paid to the fact that lime must be turned into hydrated lime before it can easily burn the branches of the seedlings. When applying white, slowly brush with a soft brush to avoid frost damage caused by the bark being brushed. Fourth, the establishment of wind barriers on the planting of a large number of closely planted seedlings, can be located in the north of the high 1.8 meters to 2 meters wind barrier cold. For seedlings with more than 2 meters of plant height and poor cold tolerance, columns can be set on the east, west, and north sides of the column, and the outer seats of the column can be used to protect the northwest wind.
Our Goji Powder uses the technique of vacuum freeze. In this method, the most part of the water in the berries is frozen rapidly to make the free water crystallize into solid. Then the absorbed water in the berries is removed through desorption. Finally, the goji berries are pulverized and produced complete goji powder. Our goji powder has the advantages of low water content, good color, plump appearance and high commodity value. It retains more bioactive substances than traditional method and can be used for producing water-soluble solid beverage. The powder is widely used in the production of functional food, beverage, healthy products, which is used as important raw material of beauty products. It is also very useful if used in the tea or also in other foods providing you a natural rich nutritional supplement.
