Orchard winter tube "four notes"
First, pay attention to pouring frozen water
The conditional orchard must be poured with frozen water. When the frozen water is frozen in the night, the water transpires too early. The water transpiration of the tree is too much to satisfy the safe wintering of the fruit trees. The watering is too late. Frostbite. Can use flood irrigation, furrow irrigation, drip irrigation and other methods, to pour, drench, to ensure that the tree absorbs enough water.
Second, pay attention to timely trunk white
The whitening work of fruit trees must be completed before the invasion of cold air, and the whitening of paintings is delayed. The pests have been safely transferred and will not be able to prevent the pests from overwintering. The southern area is generally completed by the end of December. Most whitening agents consist of water, quicklime, sulfur and salt. Generally, it is prepared according to the ratio of water 100: quicklime 25: sulfur 2 : table salt 1 , or 1 part vegetable oil may be added, and the effect is better. During the preparation, the calcined water shall be opened first, then sulphur yellow powder and salt shall be added, and the tree trunk shall be painted after stirring.
Third, pay attention to thoroughly clean the garden
Clear Garden is mainly to eliminate pathogens such as eggs, cockroaches, larvae, and other pathogens that remain on branches, fallen leaves, diseased fruits, weeds, and overwintering pests to reduce the number of pests in orchards and reduce pests and diseases in the coming year.
Fourth, pay attention to correct winter trim
Winter shears are generally appropriate one month before the tree is sprouting. Grapevine pruning is suitable for avoiding pruning from January to March when the grape leaves turn yellow to deciduous, because from January to March is the period of injury of the grape. During this period, pruning will cause a large loss of grape nutrients. Walnut tree pruning is suitable for before and after the walnut leaves turn yellow until the fallen leaves. The southern area is generally from early October to early November. Walnut saplings are suitable for pruning before and after spring sprouting. Winter shears should be pruned according to age, vigor, flower buds, and varieties. In general, young trees should be lightly cut and long-distanced. The result tree is used to determine the amount of pruning according to the yield, and the aging tree is appropriately recut and rejuvenated. A strong tree should be lightly cut, and a weak tree should be cut hard. The flower buds are moderately heavy-sheared, and the flower buds are light-cut with a small amount of flowers. The varieties with strong sprouting and branching ability have more branches and less branches.
Winter scissors mostly use methods such as thinning, short cutting, retraction, slow release, and sprouting. Be careful not to continue thinning, do not cause mouth-to-mouth injury, do not leave too much cocoon, and promptly apply healing agent after thinning. When the short cuts are noticed, the young trees should not be short-circuited. Retraction is mainly used to update rejuvenation and nurture result groups. Note that if you do not result in retraction, large branches must be moderated and you must retreat year by year. Pay attention to the competition branches, back branches, upright branches can not be put slowly, after the branches put slowly put branches, carved buds in the spring to promote the formation of the middle and short branches. Carving takes place before germination. Sprouting 0.3 to 0.5 centimeters above the bud can promote the rapid growth of the bud to form medium and long shoots.
