Description
Technical Field
The invention relates to a fixed-point germination method, in particular to a method for promoting fixed-point germination of a main trunk of acerola leaves by girdling with high survival rate, quick growth and high ornamental value, belonging to the technical field of tree planting.
Background
Terminalia microphylla (Terminalia mandaly), which are also called Terminalia microphylla and African Terminalia, originally produced African tropical, is introduced to be cultivated in Taiwan, Guangdong, Guangxi, Hainan, Fujian, southeast Yunnan and other places in China in recent years. The Terminalia microphylla has the advantages of beautiful tree shape, disease and insect damage resistance, strong wind attack resistance, barren resistance and the like, branches grow on the trunk layer by layer, the layering sense is clear, and the ornamental value is high. Is a garden tree species and a coastal tree species with great ornamental value in the southern area at present, and the demand in modern landscaping engineering is increasing.
However, as the management is not in place in the growing period when part of the nurseries are planted, the density among the plants is too high, the branches of the middle and lower layers of the plants are completely dried, if the branches are cut off when the nurseries are directly transplanted, the tree is changed into a bald trunk, and a circle of branches with caps grow on the top layer of the trunk, so that the ornamental value of the garden trees is greatly reduced.
The application of girdling and bud promoting of landscaping trees which mainly take gardening appreciation is less, and the application of the girdling and bud promoting to improve the appreciation utilization value is improved, and particularly, the girdling and bud promoting technology of the olive leaves is not reported at home.

(2) girdling: designing a first girdling opening at a position 1.5m away from the head of the trunk, designing a girdling opening every 80cm upwards from the first girdling opening, girdling for a circle but not closing, and keeping 2-3cm long primary bark to be beneficial to up-and-down conveying of partial nutrient substances, so as to prevent the trunk from withering and dying due to complete cutting of the bark;
(3) temporary planting: transferring the olive leaves subjected to girdling treatment into a beauty planting bag by a crane, righting to keep the tree body upright, keeping the soil ball in the middle of the beauty planting bag, removing the sunshade net, filling soil in layers, and filling by a wood stick pestle for assisting in filling; and supporting according to the specification of the tree and the height of the center of gravity;
(4) watering: after the trees are fixedly supported, enough water is poured and root fixing water is thoroughly poured, so that the root system around the soil ball is fully contacted with the backfilled soil; then root irrigation is carried out by using a special rooting agent for temporary planting of trees; watering at the later stage, wherein the soil is kept moist; meanwhile, water is sprayed to the tree body in time according to the weather condition for moisturizing;
(5) fertilizing: after temporary planting for 25-35 days, the tree begins to sprout below the girdling opening; after leaf extraction and aging, top dressing can be carried out, each plant is fertilized for about 100 g each time, the fertilizer application principle is a small amount of times, and the fertilizer application is carried out for 1 time each month.
(6) Killing insects: the olive leaves have strong disease and insect pest resistance, no other plant diseases and insect pests except coffee crow beetles and Aerugo beetles are found to be harmful to the nursery stock tree body, and the pesticides adopted by the coffee crow beetles and the Aerugo beetles are thiacloprid and fenitrothion missible oil respectively.
The girdling openings in the step (2) are 1cm wide and penetrate into the xylem, so that meristems between the phloem and the xylem are completely exposed to lose moisture, nutrition conveying channels of the meristems are cut off, and the primary peels reserved by each girdling opening are kept in the same direction.
In the support in the step (3), a triangular support is selected to be beneficial to the stability of the tree body, the support point is 2/3 parts of the tree height, one support rod is arranged in the windward direction, the other 2 support rods are uniformly distributed, and the support material is a bamboo rod or a fir strip; or a customized steel pipe bracket is adopted for supporting, but the cost is increased.
And (4) irrigating the roots of the special rooting agent for temporary planting of trees on the 2 nd day after the rooting agent is thoroughly watered, and then irrigating for 1 time every 10 days and continuously irrigating for 2-3 times.
The water spraying requirement in the step (4) is fine and uniform, water is sprayed for 1 time in the morning and afternoon of each day immediately after temporary planting, and water is sprayed for 1 time each day after 1 month, so that a moist environment is provided for the tree body.
The fertilizer in the step (5) is a compound fertilizer with high phosphorus and potassium contents.
The killing method of coffee longhorn beetles in the step (6) comprises the following steps: in the adult period, 3% thiacloprid is used for killing, and if the thiacloprid is larva, the trunk is perforated and directly perfused with chlorthal cleaner.
The killing method of the Aerugo scarab in the step (6) comprises the following steps: in the adult emergence period, 50% fenitrothion missible oil is adopted, and the crown is in a spraying mode; the imagoes hidden in the soil are applied with pesticide in the tree discs of the surface soil layer, and then are hoed into the soil.
The invention has the beneficial effects that:
(1) the method can be used for fixed-point germination, and has the advantages of short recovery growth period, strong plant disease resistance, high survival rate, fast growth and high ornamental value.
(2) The method is simple and feasible, has low cost and is suitable for industrial popularization.
