Embodiment 1

[0013] Embodiment 1: An embodiment of the technical method of strong rooting and circumcision of sweet cherry layering seedling cultivation.

[0014] The first step is in the growing season, select annual unlignified or semi-lignified new shoots on the tree body, and the rooting treatment site requires a length of 15 cm.

[0015] The second step is to remove the leaves within 13 cm from the base of the selected new slightly stem section, and use a girdling knife to make 4 lines of parallel equidistant spiral cutting around the stem section. The cutting depth can reach the cambium, and the cutting line The distance is 0.5 cm, and the helical circle is cut for 2 weeks, and the bark sandwiched in the middle is stripped along any two cutting lines, and the spiral xylem surface 1 is exposed after peeling.

[0016] The third step is to carry out rooting agent treatment and moisturizing embedding according to conventional techniques.

Embodiment 2

[0017] Embodiment 2: Embodiment of the technical method of strong rooting and circumcision of yew layering seedlings.

[0018] The first step is to select the annual semi-lignified new shoots on the tree body during the growing season, and the rooting treatment part requires a length greater than 2.5 cm.

[0019] Step 2: Remove the needles within 2 cm from the base of the selected new slightly stem section, and use a girdling knife to make 3 parallel equidistant spiral cuts around the stem section. The cutting depth can reach the cambium layer. The line distance is 0.2 cm, and the spiral is cut for 2 weeks, and one piece of bark is stripped along any two cutting lines, and the spiral xylem surface 1 is exposed after peeling.

[0020] The third step is to carry out rooting agent treatment and moisturizing embedding according to conventional techniques.

Abstract

The invention discloses a layering seedling culturing strong rooting girdling technology method for tree varieties with difficult rooting. The method includes the following steps that step1, in the growing season, an annual growth lignified or semi-lignified new treetop is selected, a processed part is determined according to the varieties and different thicknesses, and the length of the treetop is required to be 2-15cm; step2, according to the processed part, a stem at the 1.5-13cm position above a root are subject to leaf removal, multi-line parallel equal-distance spiral cutting is performed around the stem, the cutting depth reaches a cambium, according to the varieties and different thicknesses, the cutting line distance is 0.2-1cm, the number of lines is 3-6, the number of surrounding cycles is 1.5-3, and 1-2 pieces of bark are stripped off along the cutting lines; step3, rooting agent processing and moisturizing burying are performed according to a routine technology. Compared with the prior art, the bark is spiral and continuous, an auxin high-concentration accumulation area is enlarged while the number of nutrition accumulation parts are increased, nutrition exchanging between the bark and a seed tree is guaranteed, the rooting speed of layering seedling culturing is increased, the rooting number is increased, and the layering seedling culturing of the tree varieties with difficult rooting is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a technical method for layering and seedling cultivation of hard-to-root tree species with strong rooting and circumcision. Background technique [0002] The currently known method of layering seedlings mainly adopts cutting and ring-shaped peeling on the branches, and then embeds the wound in a moist substrate. Girdling or cutting blocks the transport of organic nutrients and auxins to the trunk direction, and accumulates in the ring-cut mouth. Nearby, the wound is urged to form callus as soon as possible and new roots grow. In order to enhance the effect, rooting agents are often used. But for some tree species that are difficult to take root, this treatment method forms few active sites for rooting, few or even no roots, and the survival rate is low; or the rooting time is too long, and the branches are easy to die. Contents of the invention [0003] In order to overc...
