Tree disorder, the master never knows
Characteristics: This type of tree is often caused by pruning and trimming for many years. It is characterized by round crown-shaped crown, large branches, many internal litchi and erect; messy delivery period, unclear master-slave relationship between branches and branches; ventilation Poor light transmission, lean limbs, and more branches and diseases.
The correct pruning method: You can not consider the tree shape, from the perspective of air and light transmission, to determine the retention of several large branches, the excess branches saw the year in addition, but should not be too hasty, should be gradual; the canopy dry branches, pests and branches Cut off; the branchlets of the internal litchi branch retract and rejuvenate and promote the emergence of new branches; the periphery overlaps, crosses, and dense branches are retracted or eliminated according to specific conditions. Can be trimmed by referring to weak trees in the outer strong.
External strong weak tree
Characteristics: Peripheral branches of tree crowns are luxuriant, while inner branches are sparsely sparse. This is mainly due to the lack of apical dominance at the base of the crown of the crown, weak growth, and flower formation, resulting in excessive results.
Correct pruning method: retract the peripheral branches of the branches and reduce the number of branches. At the same time, select the lateral branches with moderate growth and flat development instead of the original ones; do not cut the annual branches near the branches. Part of the branches should be sparsely removed, and the remaining litters in the rear should be left or not removed. They should be cut short and slow, so as to promote new branches and increase the amount of rear branches. At the same time, pay attention to the surrounding branches can retain more fruit, the rear litchi few fruit, year after year to balance the growth of the front and rear.
Crowned Tree
Characteristics: The tree is more powerful and more vigorous on the one side and less on the one side. The formation of biased crown trees is mostly caused by mechanical damage, blown by wind, or improperly trimmed pods. It depends on the specific circumstances during pruning.
Correct pruning method: 1 The main branch of the base is mechanically damaged, and another new branch is selected to speed up the cultivation of a new main branch, or a short branch is used to fill the air to solve the problem. 2 The wind can be used to adjust the canopy year by year. The upper canopy can be adjusted by pressing the air with large branches, replacing the saplings with heads, and adjusting with a buckwheat tree. 3 Improper pruning caused by misalignment is mainly due to the improper selection of the main branch of the base or the improper direction of leaving the clippings and buds. It can be adjusted year by year by methods such as pulling branches, supporting branches or stretching and binding. 4 No unilateral sprouting trees, mostly due to cold winds caused by one side of the trunk to germinate up and down to form a partial crown, can be used to sprout buds to promote new branches or high access to new branches to solve.
Big branch growth potential imbalance tree
Characteristics: A common phenomenon in the growth of pear trees. Strong as weak, weak as strong, weak as left, strong as left, weak as well as left, etc. This phenomenon may not be excessively noticeable as long as it is not obvious. If the growth potential between branches and branches is too great, which affects the growth of the whole tree, it must be adjusted.
The correct pruning method: on the strong and weak, the strong outside and weak inside the pruning has been mentioned before, here is no longer repeated, only describes the imbalance between the large branches pruning method: First, the strong branches to open the angle, ease the branches Possibility; Weak branches need to raise the angle and strengthen their position. Second, the branches on the strong branches should be controlled, more sparse core and reduce the amount of branches; on the weak branches, they should support the lateral branches, increase the number of branches as much as possible, not sparsely branches, more short cuts, and promote new branches.
The result is not a result tree
Characteristics: This type of tree is often characterized by strong tree vigor, strong growth potential, multiple branches, many upright branches, dense branches, and collisions. It is mainly due to improper pruning or left to grow.
Correct pruning method: First, it is necessary to open the backbone branch angle and ease the growth potential of the backbone branch. If there are too many backbone branches, some large branches can be removed in a year, which not only solves the problem of ventilation and light transmission, but also moderates the growth potential of the tree. Second, light shearing and slow release promoted short spurs and less short cuts. Third, remove sparsely developed branches and put upright branches on the back. Fourth, suppressing the apical dominance and stimulating multiple short twigs in the lower part.
Trunk too high or too low
Characteristics: The reason that the trunk is too high is that it is convenient to plant crops under the tree, and the reason why the trunk is too low is because of many results and the inability to remove large branches. Both of these conditions are detrimental to the growth and development of the tree: the trunk is too high, the transportation distance between the crown and the root system is longer, the nutrient consumed is more, and the tree vigor is weaker; the trunk is too low, the branches are dragging the ground, affecting the ventilation and light transmission, and easily causing the base The internal branches of the main branch are thin and weak and affect the fruit quality.
Correct pruning method: If the trunk is too low, cut off the large branches of the base mop, or use the stick to drag the base to the ground, or retract some large branches to open the light path. If the trunk is too high, the saplings can use the method of sprouting trunks to trigger new shoots. Large trees can be used to make joints or branches can be used to solve the problem. Feng Yuexiu reminded that the general trunk height of pears is 50-60 cm. In areas with flat ground or in areas with heavy rainfall in the south, or in areas with mechanized operations, tree trunks may be higher; in mountainous pear orchards, under dry, windy, cold or dense planting conditions, trunks may be appropriately shorter.
The main processing process of dehydrated pumpkin slices includes raw material cleaning, finishing and cutting, blanching, dehydration and packaging.
Pumpkins for dehydration should be selected from ripe pumpkins with good flavor, smooth skin and orange-red flesh.
Washing Dry the pumpkin in clean water to remove dirt such as mud.
Sorting and cutting Remove the stem of the washed pumpkin, then cut it into two halves with a knife, and peel off the outer skin and the inner pulp and seeds. Cut it into 3-4mm or 6-7mm thin slices (you can also use a grater to smash into filaments).
The blanched and cut melon slices are treated with steam or boiling water for 1-3 minutes, then quickly cooled with cold water, and the water droplets are drained.
Dehydration Put the blanched pumpkin slices into a baking sieve for dehydration. The drying temperature is first controlled at 45-60 °C, and then gradually increased, but cannot exceed 70 °C. Dry until the moisture content of the dry product is below 6%.
The product requires that the dehydrated pumpkin slices should be light yellow or orange, flaky or filamentous.
