The shaping and trimming technology is particularly simple, and is beneficial to culturing various tree structures and shapes.

15050 the tree can be cultivated in the form of tree,

the method comprises the following steps of: a tree structure

The tree is single-trunk double-layer, the tree is 1.5m high, the central trunk is vertically long, 3 branches are selected and reserved on the first layer at the position 90cm away from the ground, and 3 branches are selected and reserved on the second layer at the position 1.5m from the top as a first group of branches. When the upper layer of branches and the lower layer of branches grow to be more than 60cm, selecting and reserving one branch at the base part of each branch or at the position of the central trunk adjacent to each branch, reserving one branch between the two layers of the central trunk at intervals of about 20cm, adding 5-6 branches between the two layers, and using the branches as a second batch of branches to stabilize the whole tree branches at about 20. The length of the branch is controlled to be 70-80cm, and the angle of the branch is uniformly inclined downwards by 45 degrees.

Cultivation of B-tree form

and a, culturing central trunks and branches, selecting and reserving upright strong branches as central extension branches after field planting of nursery stocks, timely inserting rods to tie and guide the central trunks, and removing redundant tender branches on the central trunks at any time so as to facilitate the accelerated growth of the central branches. When the central branch grows to 1m high, remaining 90cm, and obliquely cutting off 10cm to reserve the central branch and cultivate the first layer of 3 branches. The oblique shearing is beneficial to enhancing the growth potential of the central branch of the first bud at the top end, and the lower branch of the first bud can not compete with the upper central branch, so that the effects of selecting and reserving strong central branches and culturing ideal first layer branches are achieved. And then, when the central branch grows to 1.6m, the central branch is cut at the position of 1.5m, 10cm is cut off, the second layer of 3 branches at the top end are selected and remained, and the central extension branch is not cultured. The growth potential of three branches at the top can be basically similar by horizontal shearing, and the 10cm of central branches can lead to more branch buds (4-6) sprouting under the shearing mouth, thereby being beneficial to increasing the branch quantity and selecting and reserving a room for 3 adjacent branches. Generally, the heavier the pruning, the more the number of the germinating branches under the pruning port is, the lighter the pruning amount is, and the less the number of the germinating branches under the pruning port is. After the top two layers of branches are cultured, 1 branch is cultured and selected on the central trunk at intervals of about 20cm, 5-6 branches are added on the central trunk, 1 branch is cultured on each branch at the base parts of the upper layer of branches and the lower layer of branches, the branch amount is increased, the space of a tree body is fully utilized, and meanwhile, redundant branches are thinned and removed to control the branch amount. After the first batch of branches are fruited, about 10 third batches of branches are cultured, and the number of the branches is gradually updated and stabilized.

b, twisting branches to form an opening angle, wherein when the branches on the central trunk grow to be more than 20cm, the twisting opening angle can be performed, at the moment, the central vascular bundle of a new twisted branch is in a semi-lignification state, the central vascular bundle is rotated to the base of the branch by 90 degrees, the twisting is performed, the vascular bundle is downwards pulled and pressed by an angle of 45 degrees, and the. The time for twisting the new branches is generally selected to be carried out before and after noon in a sunny day when the branches are softened, the new branches are crisp in the morning and at night, and the twisting branches are easy to crack or twist off. When the new branches generally exceed more than 30cm, central vascular bundles enter lignification or after aging, the branches are difficult to twist and are easy to kink.

c, controlling the cutting of the branches, cutting off the tips of the branches with strong growth vigor by about 5cm in advance when the upper and lower layers of branches grow to be more than 70-80cm, controlling the growth vigor of the branches, enriching the quality of the branches, facilitating the promotion of flower bud differentiation and keeping the length of the branches between 70-80 cm. In the process of pruning the dragon fruits, the time for cutting off new branches is preferably selected from sunny days, the wounds are quickly dried in the air, and the air humidity is high in rainy days, so that the dragon fruits are susceptible to rot. After the new branch is cut, the second branch grows from the tip, and is generally thinned and removed. Under normal conditions, branches grow robustly and are easy to flower and bear fruits, but the fruits are also large, but the flowers can also bear fruits on the central trunk, a plurality of buds (6-7) can be formed on some branches, and 2-3 fruits can be set on one branch at a time.

And d, culturing, adjusting and updating the branches, culturing new branches in stages and in batches along with the increase of the tree body after the branches are formed, reserving strong branches, thinning and removing weak and redundant branch buds, gradually thinning and removing old branches losing fruiting capacity, straightening the positions of the branches, reasonably occupying space and relatively stabilizing the number of the branches. And the bearing branches, the flowering branches and the subsequent flowering bearing branches are always kept on the tree body. Also, the aerial roots on the branches and trunks are thinned and removed at any time, so that the nutrient consumption is reduced. Meanwhile, the overgrown branches of the root parts are removed, space is available for the overgrown branches on the central trunk, 3-5cm is cut when the overgrown branches grow to 70cm, 10cm of heavy cuttings are left at the large part of the space, and the overgrown branches are divided into two branches and cultured into 2 bearing branches. When the trees are weak and aged, the spindly branches grown from the root parts are fully utilized to replace the central trunk, and old and weak branches are removed to cultivate the trees again. (other trees in the back, only tree structures are drawn, and the plastic pruning can be referred to the plastic pruning technology).

② single main stem shape: the tree is 1.5m high, branches are reserved at a distance of 15-20cm from the pot surface, one branch is reserved on the central trunk at a distance of about 10cm, two branches can be reserved at the top end of the central trunk, and 10-12 branches can be reserved on the first batch of branches.
