Description
Technical Field
The invention relates to the field of tree planting, in particular to a method for pruning forsythia suspense to increase yield.
Background
Forsythia suspensa (Thunb.) Vahl, a woody material, shrub or small tree. The fruit of the Chinese herbal medicine is used as a medicine, and has the effects of clearing away heat and toxic materials, and relieving swelling and dissipating stagnation. Can be used for treating wind-heat type common cold, fever, polydipsia, coma, pyretic stranguria, and anuresis. Wild forsythia in Taihang mountain areas in China has large-area distribution, and the wild forsythia in pieces is reported to be mostly distributed in mountainous areas with elevation of 500-. Fructus forsythiae likes light, wild fructus forsythiae grows fast, has many branches growing on foot, is disordered in the naturally growing tree form, has staggered branches, has empty and deficient inner chambers, does not see light at the lower part, has few fruits and poor medicinal material quality, has the average yield of about 4 kilograms per mu of wild fructus forsythiae, and has few fructus forsythiae plants due to staggered branches with disordered trees and invisible light in the inner chambers under the branches, so that the larger the plant, the more serious the staggered branches with disordered tree form are.

A method for pruning forsythia suspense to increase yield comprises the following steps:
the method comprises the following steps: fixing the trunk, namely selecting a strong and upright main branch 80 centimeters after the fructus forsythiae is planted, cutting off, fixing the trunk and promoting the development of a first-level bone branch;
step two: in the second year, the first-level bone trunk branches promoted after stem fixing are cut off at the 1/2 position of the branches, and second-level branches are promoted to form second-level bone trunk branches;
step three: for strong second-level backbone branches, the third-level branches are promoted by subtracting 1/2 of the branches through summer pruning; for the weak bone branches, winter pruning can be carried out before sprouting in the second year to promote the growth of the third-level bone branches;
step four: all the drooping branches, the thin weak branches and the cross branches except the determined bone trunk branches are pruned in the shaping pruning process;
step five: the plant characteristics of the forsythia suspense are easy to form a plurality of trunks, the number of the trunks can be kept at most by 3 in the shaping and trimming process, the redundant trunks are all removed, and the forsythia suspense can be cultivated into a natural open-heart type or a multi-trunk natural open-heart type tree after 3-4 years;
step six: forsythia pruning management, for fixed forms of Forsythia, is done annually to promote fruiting branch group formation and renewal. Pruning principle: for the germinated spindly branches and vigorous branches, the branches are cut off at 1/2 positions of the branches in winter each year and are cut off moderately, and the cut-off branches promote 2-4 fruiting branches in the same year;
step seven: and (3) performing re-shearing on the branch group which is already degenerated for more than 4 years, shearing off the branch group from 1/4 positions of the main branches (branch groups), namely shearing off 3/4 of the branch or branch group, promoting the germination of new fruiting branches, and culturing the new fruiting branch group.
Comparative example 1:
the tree shape was the same as that of example 1 except that the trimmed tree shape was different, and the tree shape was naturally grown in this comparative example.
Comparative example 2:
compared with the embodiment 1, the tree shape is trimmed to be a natural round head shape, namely the tree shape is provided with a main trunk, the trunk height is 60-80 cm, the tree height is 1.2-1.8 m, 3-4 main branches are provided, and each main branch is provided with 2-3 side branches.
Comparative example 3:
compared with the embodiment 1, the tree shape is trimmed into a spindle shape, namely the tree shape has a trunk, the trunk height is 40-60 cm, the tree height is 1.2-1.7 m, 6-10 main branches are provided, and 3-8 side groups are directly planted on each main branch.
Comparative example 4:
compared with the embodiment 1, the method has the same structure except for different short-cut degrees, and the comparative example adopts a long-length mode without cutting branches.
Comparative example 5:
the same procedure as in example 1 was followed except that the degree of shortening was varied, and the soft cut was made each time 1/3 was made for the total length of the shoot.
Comparative example 6:
compared with example 1, the cutting process is the same except that the cutting degree is different, namely, the re-shearing is carried out, and 2/3 of the total length of the branch is cut each time.
The experimental data for example 1 and comparative examples 1-3 are as follows:
the results and analysis show that the pruning has very obvious influence on the branch number, the single fruit quality and the plant yield of the forsythia suspense tree, and has no influence on the content of phillyrin. The 3 tree forms have the best effect of a natural open heart shape, and then have a natural round head shape, so the spindle shape is poorer, but the effect is better than that of the natural growth condition. The number of fruit branches formed by the natural open heart shape is the largest, and the difference between the fruit branches and the natural round head shape, the spindle shape and the natural growth is obvious. The quality of the single forsythia fruit after the shaping and pruning treatment is improved, and the difference of the quality with the natural growth is obvious. The natural open heart-shaped treated plant has the highest yield, and the yield is improved by more than 40 percent without contrast. The comprehensive analysis result shows that the yield can be obviously improved by shaping and pruning the forsythia suspense trees.
The experimental data for example 1 and comparative examples 4-6 are as follows:
the results and analysis show that the pruning of the short section has very obvious influence on the branch number, the single fruit quality and the plant yield of the forsythia suspense tree, and has no influence on the content of phillyrin. The number of fruit branches formed by medium shearing is the largest, and the difference between the fruit branches is obvious compared with that between light shearing, heavy shearing and long shearing. The quality of the single forsythia fruit after the short cutting treatment is improved, the difference is obvious compared with the long cutting, and the difference is obvious between the medium cutting, the heavy cutting and the light cutting. The yield of the medium-shear treated plants is highest, and the difference performance is very obvious compared with that of long-cut, light-shear and heavy-shear. The comprehensive analysis result shows that the yield can be obviously improved by carrying out middle-cutting and short-cutting on the forsythia suspense trees, and the yield is improved by more than 30% compared with a control.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
