Seedlings of white seedlings take 5 kg of quicklime and 0.5 kg of salt, which are respectively opened with water. After mixing and stirring, 0.5 kg of vegetable oil and 0.5 kg of lime sulfur are added to form a whitening agent. Before freezing, paint or spray on young walnut branches. on.
The plastic film wraps the young tree of walnut first to trim properly, then choose 0.03 millimeter thick plastic film, cut it into a 3 to 5 centimeters wide, 1 to 2 meters long belt, from the treetop to the base of each branch one by one, plastic The strap connector must be pressed tightly to prevent it from being blown out of action. The dressing is completed before and after the end of December, except when the membrane is inflated with flower buds.
Vaseline plus cooked lard, apply 1 part of medical petrolatum oil, 1 part of cooked lard, put it in a saucepan and heat and mix well. After cooling, use a brush or gloves and apply it to the whole tree, especially the first year or second year. It is advisable to follow the natural defoliation of fruit trees until they are frozen.
