The trunk is painted white. Applying the white trunk in time can enhance the cold resistance of the peach tree. Fertilization with a full nutrient formula. Nitrogen control, phosphorus stabilization, potassium increase, micro (trace elements), improve tree nutrition and resistance, improve life activity, conducive to frost and cold protection.
Before the frost arrives, the soil of the peach orchard is flooded with a large amount of water。In foreign countries, the tree is sprayed with water before the frost comes, and the buds and flower bones are sprayed into ice bumps, which are frozen and let them slowly melt naturally. At present, many small farms and farmers have the ability to spray water with modern agricultural equipment, and can try to spray water on the budding and flowering trees before the frost comes.
Spray antifreeze。Spray antifreeze before frost or when the garden is cleared. The ingredients of antifreeze: sugar, urea, gibberellin, trace elements containing boron plus a small amount of hormones, can also be self-formulated.
Create an orchard microclimate。Quicklime can be used to prevent frost, first crush the quicklime with a machine, and divide it into 5-7 with plastic bags5 kg pouches, scattered in advance in the orchard, before the frost comes, fill the peach orchard with water in the afternoon, wear high boots at two o'clock in the morning to sprinkle quicklime in the peach orchard, lime heat in the water, protect the tree from frost.
Ventilation or blowing. There is never frost in the well-ventilated and windy peach orchard. The low-lying peach orchard suffered serious frost damage. If conditions permit, a large hair dryer can be used to disperse the cold air gathered in the peach orchard when frost comes, so as to avoid freezing the tree.
Ignition and smoke. The smoke agent can be mixed with sawdust or firewood (90%), sulfur (2%), waste diesel oil (3%), potassium nitrate (5%), and covered with leaves and residual grass. At present, there are also commercial smart cigarette barrels on the market, which can be tried.
