"America 8" Apple Tree Sapling Management Technology
"America No. 8" has been set to a height of 100cm after planting, promoting the development of a spheroid tree. 1 Tree trim 1.1 Pruning of annual trees Before germination, at a predetermined dry height of 70cm, 2 to 3 eye injuries were performed to increase the germination rate and increase the branch amount. Before the lignification of shoots, the young shoots below 70 cm in diameter were removed. In the summer, the shoots are softened, so that the angle is between 70 and 90 degrees, paying special attention to controlling the competition. 1.1.1 For pruning young trees with long branches, large branches, and long branches, pruning branches below 70cm in winter, and selecting long branches above 70cm to leave 6~8 branches with good balance and good orientation. Among them, 3 to 4 were cultivated as main branches, the angle was controlled at 70 degrees, 3 to 4 were supplemental branches, the angle was controlled at 90 degrees, and all the branches were removed. The leaders of the center are short and the length of cuts is about 60? 1.1.2 To prune the young trees of moderate growth during winter pruning to eliminate competition branches, select 3 to 4 long branches with good orientation and strong growth to be cut short at full shoots, promote long branches, and then grow into main branches. Leaders are short-term training, and the remaining branches are thrown away. 1.1.3 The pruning of young trees with weaker growth should be cut short in winter, and the competition branches should be eliminated. 1.2 Biennial Tree Pruning 1.2.1 Pull branches before and after sprouting, the main branch is pulled to near level, auxiliary feeding branches can even droop, main branch and auxiliary supporting branches are engraved in multiple rings. From early May to early June, the main shoots and auxiliary branches on the main branches and auxiliary branches should be properly removed and the other shoots can be repeatedly picked up and twisted. In the autumn, the new shoots issued by the central leadership should be rationally eliminated. The remaining branches should be softened. The central leadership should train another 3 to 4 main branches, and 2 auxiliary branches and branches, and the central branch should have 50~. 60cm short cut. 1.2.2 When the winter shear cuts off the erect branch on the back of the main branch of the first layer, the competition branches of the extension branch of the main branch are removed, and the branches are stretched. Remove the competition branches of the central branch extension branch, extend the branch to stay 50 to 60cm short, and then select two main branches and two auxiliary branches on the central leadership. 1.2.3 During winter cutting, three or four long branches were selected as the main branch at the base, and one or two were supplementary branches, and the standing branches were removed and the remaining branches were thrown away. The central leaders must choose to retain two main branches, 1 to 2 auxiliary branches, and eliminate the central leadership's competing branches. The extension of the branches should be 50 to 60 cm short. 1.3 Three-year tree pruning In the middle and late June, girdling or engraved measures are adopted for the main branches and auxiliary branches to control the growth and promote the formation of flower buds; during winter cutting, attention is paid to balance the tree vigor, and prevention and treatment are strong and weak, and the central leaders continue to cultivate the third main branch. 3~4, 2 auxiliary branches, the main branch should be dislocated, the interval should not be less than 60cm. 1.4 The four-year-old tree basically enters the early fruit period, with 10 to 15 main branches and a tree height of 3m. The skeleton of the tree has been completed. At this time, the pruning is mainly to control the balance of the tree potential and then give birth prematurely. 2 Shushi regulation and promotion measures 2.1 Pull open angle This is a key technical measure to control the tree vigor. The main branch angle of the spindle shape is 70 to 90 degrees. The remaining branches are flattened or drooped. When pulling the branches, attention is paid to adjusting the tree potential balance by pulling the branch angles. Turn and hold a line to achieve: Pull out the level, pull out the balance, pull out the tree, pull out the level. 2.2 Branch transformation and branching technology Before and after germination, directional or non-directed injurious shoots and auxiliary branches are used to promote lateral branches, short branches are increased, long branches are shortened, branches are turned from longitudinal growth to lateral growth, and branches are formed mainly by short branches. Structure, the tree potential eased, and then laid the foundation for flowering and results. 2.3 do a good job within the tree The erect branches and redundant branches in the tree shrubs should be treated in time to avoid the “little messâ€, which is not conducive to forming, affecting the light and not forming flowers. The methods of removing, twisting, folding and pulling the branches are mainly adopted. To deal with. No branches are allowed within 10cm from the trunk. The result is that the branch spacing is 20~30cm. Through the treatment of branches within the oyster, the resulting parts of the sapling are properly configured and gradually shifted outward. 2.4 Growth Regulators Promote Flowers Spraying 300 times 10% paclobutrazol in early May, and spraying 150 times 10% paclobutrazol when the autumn shoots start growing in mid-July, it can be sprayed several times in succession depending on the situation, and the effect can be achieved. 2.5 Ringing The hustle and bust of the main trunk was carried out in mid-May in Mongshu. The width of the mouth was 0.5?, and the paper was protected. After 15 days, it was withdrawn. For unbalanced treetops, girdling or multiple girdling of the main branch is required. 3 Pest control During saplings, prevention and control are mainly done to protect the leaves. The main pests and diseases are: beetles, green-lipped stink bugs, aphids, subalgae, leaf roller moth, red spider, early defoliation and so on. According to the actual situation, medications are available, pyrethroids can be used to control green-lipped mycosis, leaf roller moths, etc., Imidacloprids are used to treat aphids, and Diflubenzuron is used to treat Hymenoptera 3, and Radix is ​​used to treat red spiders. Bordeaux fluid control. 4 Flower and fruit management The four-year-old trees entered the early fruit period. At this time, while doing a good job of soil fertilizer and water, pruning, pest and disease control, they focused on the management of flowers and fruits. To adjust the balance between vegetative and reproductive growth of the tree, prevent premature aging of the tree. Sparsely growing and fruiting were carried out in time to control the load and the per mu yield was 2000kg. The specific method is to maintain an inflorescence at an interval of about 15cm in flowering period, leaving one central flower and one side flower for each inflorescence, artificial pollination; fruits and vegetables after 20 days, leaving fruit with a positive fruiting shape or robust fruiting branches on both sides, fruit on the back Sparse.
Our cognitive training including child speech therapy, scene training instrument, cognitive coach, cognitive coach, his cognitive perception system components is one of the high-tech assistive devices, general cognitive awareness training is through the use of computer software integration of multimedia material library and the human voice, the application of the concept of cognitive awareness training on the multimedia platform, is advantageous for the case.
