The design aims to timely remove sprouts and branches below 50-60 cm of trunk height in the first year after the green pepper is fixedly planted, the other branches below the top tip adopt a branch twisting or pressing measure to enable the branches to grow downwards to serve as nourishing branches, the top tip is kept growing upwards in a single-head mode, competition on the top tip can be reduced, trunk lengthening and thickening growth are promoted, and stable framework support is quickly established.
Meanwhile, in the second, third and fourth years after planting, the southeast side of the first main branch, the southwest side of the second main branch, the northeast side of the third main branch, the northwest side of the fourth main branch and the north and back side of the fifth main branch are mainly considered that China is in the northern hemisphere, the reserved branches of fruit trees follow the principle that 'no south is left at the upper part and no north is left at the lower part', the base angle of the main branches is 90 degrees, namely, the base angle is opened, the top end advantage is controlled, the branch development is promoted, and the phenomenon of bare legs does not occur at the base parts of the branches; the main branch tip angle of 70 degrees and tip head single-head growth are to maintain certain top end advantages and growth vigor and promote main branch lengthening and thickening growth.
The method is characterized in that the top advantages of branches are controlled, and lignification and flower bud differentiation are promoted by twisting or pressing branches of fruiting mother branches in the next year; the branches of the green prickleyash are in autumn after 9-10 months, and are in a relatively soft stage, and the branches are twisted or pressed too late, so that the branches are brittle and hard and are easy to break, and early, the branches are easy to promote and can not be lignified.
Meanwhile, the top end of the fruit mother branch is changed into the base of the branch which is usually the highest point after the fruit mother branch drops, and the residual nutrient substances and moisture after flowering and fruiting can promote the base of the fruit mother branch and the main branch which grows transversely to germinate and extract new branches upwards or laterally, so that the purpose of synchronizing the fruit and the long branch in different spaces is achieved.
Meanwhile, after the fifth-year shaping and trimming of the green peppers after the field planting is finished, the tree shape is kept unchanged, the peppers are picked and fruiting mother branches are cultivated according to the fifth-year shaping and trimming method of the green peppers after the field planting, and the fruiting mother branches are updated every year.
Improvement by evacuation and stratificationThe tree shape can fully utilize the three-dimensional space, improve the illumination condition of the inner bore of the crown, and the effective fruit bearing space of the tree containing tree body is 3m from the prior tree shape 3 Increase to 7m 3 The seedling density is reduced from 110 plants/mu to 74 plants/mu, and the actual effective result space is 330m 3 The number of the per mu is increased to 500m 3 The yield of the green Chinese prickly ash fruit trees is greatly improved per mu. Meanwhile, flowering and fruiting in the same year and cultivation of bearing mother branches in the next year are carried out synchronously in different spaces, so that the flower bud differentiation quality in the next year is improved, the fruit picking time is prolonged, the defects of occurrence of multiple branches on the upper parts of bearing mother branches, poor growth of new branches, bore shading and the like in the existing 'parallel bearing and long branch' pruning method are overcome, production links of applying a large amount of tip promoting chemical fertilizer in summer and applying 'aging promoting' medicaments for multiple times in autumn and winter in the prior art can be eliminated, the production cost is greatly reduced, and the product quality is improved. After the tree-shaped structure is fixedly formed on the crown framework, pruning is mainly carried out by twisting or pulling branches, pruning is assisted, short-cut and pinching are avoided, the pruning workload is small, management is convenient, the tree-shaped structure is clear in arrangement, the technology is simple and easy to understand, and the tree-shaped structure is easy to master and popularize.
In some specific use scenes, when no proper branch culture main branches exist at corresponding positions on the central trunk, bud carving measures can be adopted to promote new branches before germination in spring of the year; when the method is implemented, the technical personnel in the field can select to culture the main branches in advance or in a delayed manner according to the branch condition on the central trunk; when the selected main branch is thin and soft and droops, the main branch can be bound and fixed by a bamboo pole at an angle of 90 degrees with the main branch, after the main branch is thickened, the binding is removed, and the branch head naturally rises to reach a standard angle; in the branch selecting height, the technicians in the field can adjust the position of the main branch on the trunk within 10cm from top to bottom; in the branch selecting direction, the position of the first main branch and the position of the second main branch can be interchanged, and the position of the third main branch and the position of the fourth main branch can be interchanged according to the actual position of the growth of the branch on the trunk.
When the top tip of the central trunk is thick and strong and is not easy to pull as a main branch, a branch in the direction of the due north can be found near the central trunk with the height of 2.4m as a fifth main branch, and the upper part of the central trunk is cut off and the head falls; when the length of the main branch is intersected with that of the adjacent plant main branch, a branch head growing obliquely can be selected as a new tip head, and the original tip head is truncated or pulled down to be used as a result mother branch; when the result of the mother branches is too long after the mother branches drop, the management operation is influenced or the mother branches contact the ground, and the technicians in the field can cut the mother branches appropriately; finally, in order to avoid the mutual influence among green peppers, the distance between plants is preferably 3m when the nursery stocks are planted.
