Description
A method of reducing density of overcrowded orchard
The invention relates to a method of reducing density, in particular to reducing density
of overcrowded orchard.
Fruit tree is an important economic forest, which can meet people's living needs.
However, the phenomenon of orchard canopy, especially apple orchard canopy, is very
common. It has caused outstanding problems such as poor ventilation and light
transmission in orchards, inconvenient operation and management, serious occurrence of
diseases and insect pests, poor fruit quality and economic benefits, and restricted the
sustainable development of apple industry. Therefore, the transformation method of
overcrowded orchard is an important planting method. In the existing transformation
methods for overcrowded orchards, the general transformation methods such as lifting dry
and falling head have certain effects in the early stage, but with the expansion of trees, the
phenomenon of overcrowded later followed, which cannot solve the problem
fundamentally and thoroughly, and seriously affects the yield and fruit quality of orchards.
In order to overcome the above technical shortcomings, the invention aims to provide
a transplanting and density reducing planting method for the overcrowded orchard, thus
shortening the time for the orchard to reach the production capacity and prolonging the production cycle of the orchard.
In order to achieve the above purposes, the invention adopts the following technical
scheme:
The method comprises the following steps: In September and October of the year
before transplanting, an annular ditch is dug at 50-70cm around the trunk of the tree to be
moved, the lateral roots were cut off, and then organic fertilizer is filled. Transplanting
from October to November, watering one week before transplanting, cutting the tree weight,
selecting only the backbone branches and branch groups, and marking in the south of the
trunk. When transplanting, taking the soil lump embedded in the fruit tree. Putting the soil
lump of fruit tree in the planting hole to ensure the planting orientation is consistent with
the original according to the mark on the trunk, carrying out field planting of fruit tree, with
no less than 50kg of organic fertilizer in the planting hole. Irrigating when the backfill soil
is 20cm away from the ground, irrigating again when the planting hole is filled, and pile
-30 cm of soil at the base of the trunk after the water permeates to protect moisture and
prevent cold. After transplanting, painting the cut of the tree, brush the trunk and main
branches with white agent, spraying the branches with 1% urea before germination, as well
as 0.3%~0.5% urea once every two weeks after leaf spreading, spray continuously for 4-5
times, meanwhile, removing all flower buds. Then, the transplanted fruit trees are shaped
like spindles, and the retained fruit trees are shaped, as the crown of the tree being enlarged.
Further, the whitening agent comprises the following components in parts by weight:
0.5-1 part of lime, 1.8-2.2 parts of lime-sulfur mixture, 0.40.6 parts of lard, 0.40.6 parts of
salt and 100 parts of water.
Further, the steps are described in the following details:
(1) Determine whether to transplant between plants or between rows according to the
rate of canopy crossing in the original orchard; in September-October of the year before
transplanting, dig a circular trench of 60-80cm in depth around the trunk of the tree to be
transplanted at 50-70cm, cut off the lateral roots and fill in cooked soil mixed with fertilizer
to promote wound healing and sprouting of new roots.
(2) Transplanting in October-November, watering thoroughly a week before
transplanting, pruning the tree, selecting only the backbone and branches, cutting out all
other types of auxiliary branches and marking the trunk due south; transplanting with a
mound of soil 60-80cm in diameter, wrapped in plastic film.
(3) The volume of planting hole is set as 0.9 - 1.1m3 , the excavated raw soil and
mature soil are separately placed, the mature soil is mixed with high-quality soil and
miscellaneous fertilizer of no less than 50kg per hole, and backfilled. When the backfilled
soil is 20cm away from the ground, water is poured, and the hole is dug according to the
size of the root system after water penetration; according to the mark on the trunk, the
planting direction is consistent with the original. After the tree is righted, fill the hole with
mature soil and organic fertilizer to make the neck of the original root level with the ground;
irrigate immediately after planting, and pile 20 ~ 30cm soil at the base of the trunk to keep
moisture and prevent cold after water penetration.
(4) After transplanting, paint the cut of tree body. The trunk and main branches were
prepared with whitening agent according to the weight ratio of lime 0.5-1 part, lime
mixture 1.82.2 parts, lard 0.40.6 parts, salt 0.40.6 parts and water 100 parts, which were whitened with brushes to protect the trees from wintering safely. Spray branches with 1% urea before germination, spray 0.3%~0.5% urea every two weeks after leaf spreading, spray continuously for 4-5 times, at the same time, remove all flower buds, apply quick acting fertilizer in combination with watering in growing season, apply base fertilizer early, and control pests and diseases as soon as possible, spraying medicine no less than 7 times a year..
(5) Transplanting new garden pruning according to spindle shape, when cutting in
winter in the same year, it is more cut and less sparse, promoting new shoots, accelerating
the recovery of growth, and cutting off all flower buds; In summer, remove all competitive
tips, and when the main branch angle is less than 80, open the angle by means of support,
pull and fall; For the new shoots with strong growth and good orientation, take the branches
to the horizontal shape in late August and gently pick the heart. After that, the trees were
pruned according to the standard of spindle high-yield tree shape year by year.
(6) In order to slow down the overall growth trend of trees and promote the growth of
tree crown, the amount of fertilizer applied each time was increased by 10% compared with
that before transplanting, and the amount of watering was also increased appropriately, so
that the orchard coverage rate in the growing period could reach about 90% as soon as
possible.
The invention transplants the big trees in the overcrowded orchard, doubles the row
spacing or spacing to open the light path, and builds a new orchard with the moved trees,
so that the overcrowded orchard can be fundamentally and efficiently controlled, and the
orchard mass production can be achieved in 3-5 years.
The present invention is further described in combination with the embodiments. The
following embodiments are intended to illustrate the present invention rather than to further
define the present invention.
