According to the author's findings in Fufeng, Laoshan, Fengxiang, Baocang City Chencang District, the problems that existed after the apple tree reforming in the north Anhui area are proposed, and the spring-based supporting management techniques are proposed. For GuangGuoNong reference: 1. Continue to handle the cut sorghum mouth. Because of the large number of wounds of the apple trees after the great transformation, if these wounds are not dealt with in time, it will not only affect the extreme weakening of the tree vigor, but also cause the black water to flow, causing more serious rot. Great happening. Therefore, the apple trees that have undergone a major transformation should be carefully examined line by line. All those who cut kerfs and wounds without timely handling should do a good job and deal with them. You can use Shukang, 20% rot Kangbao, fruit rot and other chemical protection agent to smear and protect it. Anything that is not bandaged should be repackaged to protect it from water loss, shrinkage, decay, healing, and good results. 2. Before budding sprouting, directional budding is performed on the annual buds of Wangwang, the moderately strong and strong branches, and the buds without the main stem. The back buds are carved behind the buds, the lateral buds are carved in front of the buds, the uprights are carved in front of the buds, the large branches after the transformation are all carved in front of the buds, the buds on the middle pole are above the buds, and the buds are on the back side of the buds. Germination is the first step to restrain the growth potential of the back buds, so that the growth of the back buds is slowed down, and it is not easy to take a strip. The growth of the tree can be basically stabilized. Directional sprouting 0.3-0.15 cm in front of the bud, pulling it along with a hacksaw or a hand saw and injuring the wood. The length is 1/2-1/3 of the circumference of the stick and the depth is 1/1 of the stick's thickness. 3-1/10, those who need to draw strength should follow the requirements of early, near, deep, and long, and need to draw small and weak branches should follow the requirements of late, far, shallow, and short. Sprouting the trunk should be carried out 7-10 days before germination. During the drawing, the branchlets should be carried out in the budding stage. 3, wipe the buds due to the apple tree winter and spring after the big change, remove some of the large branches (main branch, large lateral branch), so that the relative concentration of storage of nutrients, combined with most of the stimulation of the wound, can easily cause the saw cut mouth and shoots on the back site germination A large number of new shoots, shoots, except for the bald area near the germination site or left empty, leaving a lateral branches, the rest should be erased as soon as possible in order to save the nutrients of the tree, usually once every 8-10 days. 4. Pulling branches in time will have a decisive effect on the promotion of flowering of Fuji apple trees. All apple trees that have undergone major transformations in the winter and the spring should implement the pull branch technique. The saplings should begin at the time when the sap flows in late March. The resulting 2-3 year old twigs of the big tree should start from the late sap in late March to early April and begin to move according to the target tree shape after the transformation. Pull the sticks. The modified spindle shape, the lower main branch angle should reach 90 degrees, the upper small main branch, the base angle should reach 95-110 degrees, and the small main spindle branching angle should be 100-110 degrees. When pulling the sticks, a push-pull, two-pull, three-pressure, four-position pull-pull method is used to make the branches straight and do not pull into bows. In the pull branches must be corrected only pull the lower branch, do not pull the upper branch, or only pull the big branch, do not pull it on the dumping of 25-30 cm above the bad habits. For perennial branches, the main branches of the various branches are difficult to open. A multi-saw method with three saws, five saws, and eight saws can be used under the back of the base. Generally 3-5 cm deep, depth of 1/2-1/3 of the diameter of branches, using support, pull, pressed into a horizontal shape, if the above method is not in place, can be suspended in the base back clods to achieve the branches Level prevails. To ease the tree potential and make it a flower, the result of the coming year. 5, suppress the top and promote Meng in early April when germination, suppress the top to promote Meng. The purpose is to control the apical dominance growth and increase the vegetative accumulation of the shoots in order to promote flowering and to culture short and medium shoots. When germinating, the 5-10 cm buds of large buds formed without taking into account the flowering buds of the large buds were picked up by the buds, and then cut at the base of the nucleus and the middle ring to slow down the buds, which is beneficial to the rear buds. Germination, fullness; for the twigs of imaginary twigs that are more than 5-10 centimeters in diameter, they can be hand-turned in the middle of the shoots while licking off the top buds. From strong to moderate, it promotes flowers. 6, picking the heart to the leaf, promote the weak and strong is to remove the 3-5 pieces of young leaves on the top of the annual branches, if the position of such branches is free, do not engage, let the natural growth occupy space, if there is no space Take the method of picking up the leaves and going to the leaves, and the shoots are even and full. The methods adopted on the same team are different and should be determined flexibly. 7. Transplanting wounds will change the positions of Yang and Yin sides of the branches and change their growth points. The method is: Turn the branches 180 degrees out of the right hand to hear the xylem slightly. 8. Separating the branches to cut short branches and weakening the growth potential. Before the result of flowering in the next year, sprouts are cut every 5-6 times (that is, intervals of about 20 cm), and the buds are flanked by buds. After the shoots have been cut, the purpose of this is to disperse and weaken the nutrient moisture and nutrients of the growing trend, and when the end of the year the short branches of 5-10 cm (called old man beard) will facilitate the results of the coming year. 9, to promote the control of budding, in Wang Branch, strong and strong branches of the base 2-4 to wear a ring cut together, mainly to solve the problem of closed orchards, in addition to transform the tree, adjust the tree structure, to promote Draw the sticks. After triggering the restraint, if the front of the restraint grows weaker, remove the restrained branches in time. If the former minister is restrained and strong but not weak, it can be used to inflict injury, take branch softening, and take heart to go to leaf buds. This will allow diversionary forces to be diverted into squid branches, which can be fruited in the coming year.
