Vegetables prevent cold

Cold spring has various degrees of chilling injury to spring vegetable seedlings, fruit and vegetable production in protected areas, and early-ripening vegetable production in open fields, resulting in various losses such as rot, dead seedlings, falling and fruiting, and early convulsions. Therefore, we must be vigilant for the cold and early prevention work. 1. Strengthen cold-time exercise at seedling stage and improve the cold resistance of seedlings. After the seedlings emerge, the seedbed should be ventilated, and gradually increase ventilation with warmer weather. The seedlings should be subjected to low-temperature exercise to improve the cold resistance of the seedlings and to adapt to outdoor low-temperature environment. 2. Increase protection facilities. There are two ways to do this: The first is to set up a wind barrier. Wind barriers should maintain a relatively close distance, usually about 2 times the wind barrier height is appropriate. The second is planting trenches and covering the mulch. When planting vegetables in early spring, ditch planting can be adopted. The ditch depth requires more than the height of the vegetable seedlings, and then cover the mulch on the ditch. 3. Warming temporarily. When the cold current comes, temporary heating can be performed in the nursery shed or production shed with the help of a simple coal stove to increase the temperature inside the shed and prevent freezing damage. However, open fires should not be used to prevent fires. 4. Irrigation. When the temperature drops rapidly, especially when the local surface temperature drops below 0°C, a large amount of well water can be poured on the ground to substantially increase the ground temperature. This method can increase the ground temperature from 0 °C to 8 °C, to avoid frost. 5. Smoke smoke. On a frosty night, smoking in the fields can effectively reduce or avoid frost disasters. However, it should be noted that the smoke point should be properly dense so that the smoke screen can basically cover the whole park; the lighting time should be appropriate and should be ignited in the upper wind direction, from midnight to 2-3 o'clock in the morning, until the smoke still covers the ground before sunrise. the best. 6. Water spray. Before the occurrence of frost, spraying the water on the surface of the plant with a sprayer can slow down the body temperature and increase the content of water vapor in the atmosphere. The water vapor condenses and releases heat to mitigate frost damage. 7. Cultivator. Cultivating before frost can reduce the degree of frost damage. Because the temperature in the spring rises gradually, after the clay is loosened, it can absorb and store the solar heat energy. Once the frost comes, the frost can be relieved because some heat has accumulated in the soil.

Goji Berry ( [Goji" means [happy") , also called wolfberry, has been used for thousands of years by herbalists in China to protect the liver, help eyesight, boost immune function, improve circulation, and promote longevity and overall well being. It has only recently gained popularity in the west, it has become so polar, in fact, the Time Magazine recently named the Goji berry as [super-fruit" of the year. A big reason why Goji berries have quickly become a favorite nutritional supplement is that its impressive list of ingredients. The Goji berry, also called the wolfberry, is a bright purplish red or purple red berry that comes from a shrub that is native to China. In Asia, goji berries have been eaten for generation in the hope of living longer.
