Description
Technical Field
The invention relates to the technical field of fruit tree planting, in particular to a nutrition dispersing and slow-releasing pruning method for mature peach trees.
Background
In recent years, the pruning mode of fruit branches in peach production is mainly long-tip pruning. The long-shoot pruning is a bearing branch processing method which does not cut off annual bearing branches, selects and retains long bearing branches for bearing, and completely thins and removes the rest bearing branches. When long tips are pruned, the branch retention density is generally 1 long bearing branch per 15-20 cm of the skeleton branch and the large bearing branch group, the distance between the bearing branches on the same side is generally more than 40 cm, and the branch retention amount of the whole tree is 50-60% of that of the traditional short-cut pruning method. The length of the bearing branches reserved by long-tip pruning is 40-60 cm. Medium and long branches shorter than 40 cm and overgrowth fruit branches larger than 60 cm are uniformly thinned in principle under the condition that the number of the branches of the tree body is enough, but some short fruit branches (smaller than 5 cm) and bouquet-shaped fruit branches can be properly reserved. The branch retaining amount per unit area after pruning is 0.8-1.2 ten thousand per mu.
However, the pruning method has less branch remaining amount and large pruning amount in winter, but no suitable machine for replacing manual pruning at present causes large labor intensity and high cost for fruit growers; and the yield is low, which causes the growth in summer and increases the summer shear.
Therefore, the problem to be solved by the technical personnel in the field is how to provide a peach tree winter pruning method with high yield and low cost.
Disclosure of Invention
In view of the above, the invention provides a nutrition dispersion and slow release pruning method for mature peach trees.
In order to achieve the purpose, the invention adopts the following technical scheme:
a nutrition dispersing and slow releasing pruning method for mature peach trees is characterized in that the annual bearing branches are not cut short when the bearing branches of the mature peach trees are selected and left in winter, except for bone trunk branches and long bearing branches at the branch heads of bearing branch groups larger than 30 cm, the middle-short bearing branches are mainly left at other parts, and the branch remaining amount after pruning is 2-2.5 ten thousand/mu.
Preferably, the proportion of the various branches to the total branch remaining amount after pruning is as follows: 3-5% of over-long branches with the length of more than 60 cm, 15-25% of long branches with the length of 30-60 cm, 30-40% of middle branches with the length of 15-30 cm, 25-30% of short branches with the length of 5-15 cm and 15-20% of bunch-shaped branches with the length of less than 5 cm.
Preferably, for the variety with upright tree posture, oblique branches or horizontal branches are mainly reserved; for the variety with open tree vigor, oblique branches are mainly reserved, horizontal branches are reserved in the 1/5 area at the upper part of the trunk branches of the tree body, and middle long branches are reserved at the back upper part of the 1/3 area at the lower part of the trunk branches of the tree body.
Preferably, for peach trees with vigorous growth and high proportion of long branches, the tree vigor is promoted to be alleviated, branch class conversion is promoted by releasing medium-grade bearing branches, and more medium-short bearing branches are formed as soon as possible; meanwhile, the branch remaining amount is corresponding to a pollenless variety, and a variety which is easy to drop fruits before deep picking in a stem depression is increased in short branch proportion and total branch amount, and the total branch amount is increased by 15% -20% compared with that of a common variety.
Compared with long-tip pruning, the branch remaining amount is increased by 2-3 times, and the method has the advantages of dispersing nutrition, controlling vigorous growth, reducing winter pruning amount and summer pruning amount, and reducing the pruning labor by more than 40%.
The investigation finds that the medium and short fruit branches are adopted for fruiting, and the fruit branches have large branch remaining amount, multiple growing points and relatively dispersed nutrition, so that the long branch amount in the growing season is reduced, the pruning amount in summer can be reduced, the medium and short branch updating capability is improved, the tree body illumination condition is improved, and the fruit quality is improved.
