1 trimming of the young tree. Saplings often use the characteristics of abdominal buds and apical buds to control the shoots to promote the shoots of young trees and cultivate a large number of resulting shoots. The method of wiping shoots is:
When the shoots reach 2 to 3 centimeters in summer and autumn, they are wiped off by hand and “go to stay early to stay less,†every 3 to 4 days. In a certain period of time, the more young shoots will be germinated, the more the last shoots will have 3 to 4 new shoots after 15 to 20 days. At this point, the shoots can be stopped and the shoots can grow. It's called tipping. In order to make the shoots neat, the buds must be thoroughly wiped out the day before the shoot is thrown, and the short shoots that germinate soon must be erased. In addition, for the high part of the people should be wiped 1 or 2 times or 4 to 7 days late, let the new shoots of the site grow longer, after several shoot period adjustment, and gradually balance the crown. Under normal circumstances, each spring, summer and autumn shoots 3 times, in summer and early mid-June put shoots, put on autumn shoots in mid-August, after planting the 3rd and 4th year results.
For trees that prepare results for the next year, pay attention to the amount of autumn shoots and summer shoots. The number and quality of autumn shoot growth are related to summer shoots. The summer shoots were put down too late, the number of germinations was numerous and short and weak, and the number of autumn shoots also decreased. The amount of summer shoots is moderate and robust, and the number of autumn shoots increases. Generally, 40% to 50% of spring shoots can shoot at summer shoots, and 70% to 80% of autumn shoots can shoot at autumn shoots. The tipping must be closely coordinated with the fertilization. The organic fertilizer should be applied 20-30 days before the tipping period, so that part of the buds can be wiped in the first half of the month before the tipping, and then the nitrogen fertilizer can be applied immediately before the tipping. The new shoots are germinating and dense; the shoots should be fertilized according to the strength of the new shoots, especially the shoot shoots of autumn shoots should not be excessive, otherwise they will trigger late autumn shoots or winter shoots. It is best to have cool, rainy showers during the period of dewatering. The soil moisture should be sufficient. Such as arid hot should avoid tipping, focus on the prevention of leaf miner. When the summer and autumn shoots grow to 5 to 6 cm, such as branches too dense, it is necessary to timely sparse, leaving 2 to 3 per base tip (fall shoots can stay more). There are too many shoots, and the shoots are weak; the shoots are too few and the shoots tend to be long. The length of autumn shoots of red meat pomelo is preferably 20-30 cm. Winter shoots should be erased.
2 result tree pruning. The result of the tree pruning varies depending on the age, the outcome, and the pruning period. Winter cuts are carried out after fruit picking and before budding. Generally, pruning can be started after fruit picking, and mid-high altitude areas should be performed before spring sprouting. The winter shear is mainly used to cut dry branches, branches and branches of diseases, weak branches, cross branches, declining branches and resulting mother branches, etc., to adjust the nutrition of the tree, and to control the proportion of shoots. Some branches are also properly retracted and pruned to promote As a result, the mother branches are numerous and strong, ensuring high yields for consecutive years.
In the initial result period, it is necessary to ensure that the crown develops well, resulting in a rapid increase in the number of mother trees and prevention of fruit drop. To ensure that the crown of the initial result tree continues to develop well, continue to select the extension branch of the main branch and the sub-main branch, ensure that the growth is straight and upward, and properly remove the fruit on it to speed up the formation of the crown. The extension branches of the transverse branches growing obliquely also minimize the result and extend the crown around. Cut off the inner hail and the top of the dense summer and autumn shoots, the base to take 1 to 2 leaves for the spring shoots of the results of the mother shoots, the remainder cut off. The branches around the crown are selected to leave the summer and autumn shoots. Each shoot has 1 to 2 summer and autumn shoots that grow diagonally to accelerate the canopy formation. The inside and the lower branches of the canopy are kept as far as possible to allow the flower to bloom, and the mother branches with a depth of 30 to 40 cm below the ground are cut off to reduce the infection of anthrax on fruits near the ground.
Short spring shoots (15 cm in length) and eradication of summer shoots are effective measures to prevent fruit drop, increase effective fruiting and reduce pests and diseases.
The adult result tree is a three-dimensional result of the tree crown. The main branch happy round head-shaped canopy needs to keep the canopy wavy. There is a “skylight†and the trees are kept at an appropriate distance. The branches that protrude from the middle of the crown should be cut off to prevent shading from causing the lower branches to die. The upper and lower branches must not overlap each other, and the interior of the canopy has good light transmission. Naturally happy-to-shape canopies should pay attention to the toppings, short cuts or deletions of the formidable branches inside the crown; when the top of the canopy is too strong and dense, the strong branches or the appropriate deletions are cut off to maintain the tree shape.
The branches of the lower canopy should be cut properly when they intersect with adjacent trees. The leggy branches that need to be used should be timely picked up or bent, and they need not be removed in time. If the result of fruit picking after the branch is slender, weak, yellow leaves or no leaves, can be removed from the base of the resulting branches; if the result is weak, the mother can be removed from the base of the result. Within the canopy, dead branches, slender weak branches, diseased branches and leggy branches should be cut off. The result of the pruning of the tree was mainly debrided, combined with short cuts, retraction, removal of cross-branches, over-closed branches, and retraction of long branches.
Both stems and fruits consume assimilation substances, and it is estimated that the assimilation of citrus branches, stems, and roots consumed from 5 to 30 years is 3 to 10 times the fruit consumption. The area of ​​young and young leaves grows rapidly and the yield is high; when it enters a certain age, the leaf area will stop increasing, while the branches will gradually increase, the number of branches will increase, and the transport distance of nutrients will increase. The number of assimilation materials in stems has increased year by year, while that in fruits has decreased year by year, and shoot growth has turned to decline. If the plants are crowded with each other and the canopy is closed, there will be fewer new shoots, and the internal and lower canopies of the canopy will die, accelerating the decline, and the fruit yield will decrease rapidly. Therefore, the proportion of red pomelo and grapefruit branches should not be too large, and the branches should be updated in time. Each year, a part of the weaker branches should be trimmed to reduce the transport distance of nutrients, reduce unnecessary consumption, and improve light, so that light penetrates into the inside and the lower part of the crown, adding new foliage, and rejuvenating the tree.
Winter cuts are carried out after picking fruit until the spring shoots sprout, depending on the local climate. Weed out the redundant main branch, sub main branch and side branch from the base, and weed out 1 to 2 each year. Retreat the top of the crown at the top of the canopy and the axillary branch or branch of the cross between the rows. Keep the height of the tree below 3.5 meters and there is more than 20 cm between the rows. Cut out the strong standing branch and the long branches, and the dense branches that affect the light and the weak branches below the branches. Branches with branch diameters of 1 to 2.5 cm are retracted in different ages, and stubs of 5 to 15 cm are collected for stubble branches or weakened branch groups for short cuts. Pendulous branches are retracted before horse-branch sticks or branches and bald. Leave a short cut of 5 to 10 centimeters, and the number of prunings per year is 25% to 30% of the total number of branches.
Summer cuts are generally performed in late May. Delete overly dense, redundant main branch, sub main branch and branch group, retract inconsistent, cover each other long branch, cross branch. Eliminate summer shoots and control the growth of autumn shoots.
3 aging tree rejuvenation pruning. Aging trees are weak, with little or part of the shoots dry, and they should be rejuvenated in time to increase production and extend economic life. Take main branch updates, explicit updates, or rotation updates as appropriate. The management of the canopy after renovation is the key to success or failure. Sun protection, sparse buds, fertilizer and water management and pest control should be done.
When the shoots reach 2 to 3 centimeters in summer and autumn, they are wiped off by hand and “go to stay early to stay less,†every 3 to 4 days. In a certain period of time, the more young shoots will be germinated, the more the last shoots will have 3 to 4 new shoots after 15 to 20 days.
