There are four ways to prevent vegetable frost. First, spray water and frost protection: When you hear a frost forecast, you can spray fresh water on vegetables or small arch plastic films 2-3 times at 2-3 o'clock every night, once every hour. Since the humidity around the leaves is large at this time, the dew point is significantly increased, and generally no frost is generated. Second, the water is frost-proof: The water is poured the day before the invasion of frost is foreseen. Because of the large heat capacity of the water, after the ground is wet, the humidity of the air layer near the ground increases, and the reverse radiation increases, and the temperature on the ground and near the ground decreases. Wet soil has a larger thermal conductivity than dry soil. It can store more heat during the day, store it in deep soil, and release it again at night, thus delaying the decrease of temperature near the surface. Third, it is covered with frost protection: Although the moisture resistance of plastic film Yes, but its surface is prone to frost, such as covering a film outside the greenhouse or taking a double shed is an effective measure. Can also cover a thin layer of ash and other objects in the shed, and also protect the seedlings; Fourth, the wind barrier to prevent frost: the wind can accelerate surface evaporation of water, reduce the temperature, take away the plant heat. The grasshoppers, which are about 1-1.5 meters high around the greenhouse, are provided with windbreaks at the windward side to increase the ground temperature and enhance the prevention of the cold air.
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.
