Problems solved by technology

Green branch cuttings are generally carried out from June to September. The current cutting method is suitable for some garden plants that are easy to root, but some garden plants that are not easy to root have a low rooting rate, a low rate of first-grade finished seedlings, poor quality seedlings, and poor implementation efficiency.

Embodiment Construction

[0017] The present invention will be described in detail below in combination with specific embodiments.

[0018] 1) Prepare the seedbed: use bricks to build the seedbed wall, the width of the bed is 1.0-1.2m, and the height is 0.5-0.6m. The lower layer of the bed is laid with large pebbles of 10-15cm, the middle layer is laid with small pebbles of 10-15cm, and the upper layer is laid with cutting substrate 25cm. -30cm, such as vermiculite, fine river sand, perlite, etc. The day before the cutting, spray the seedbed with 600 times carbendazim for sterilization. Set up an automatic control spraying system on the seedbed.

[0019] 2) Collection of seedlings: In summer and autumn, generally from June to September, select the healthy, semi-lignified branches of the mother tree that year, and collect the seedlings. The time for collecting seed strips should be before 8:00 in the morning, when photosynthesis and metabolism levels are low. Before the collected seed strips are cut ...

Abstract

The invention discloses a method for promoting rooting in green branch cutting of plants in a garden. The method comprises the following steps: a seedbed is prepared, in summer and autumn seasons, current-year, robust, disease-pest-free and semi-lignified branches of a mother tree are selected, the collected seed branches are all soaked into an aqueous solution of carbendazim and dithiothreitol, the lower ends of the seed branches are cut off under water and discarded, the seed branches are cut into cuttings, each cutting retains a plurality of buds, and upper-part leaves are retained; the lower ends of the cuttings are cut into oblique openings, the upper ends are cut into flat openings, soaking is performed in an aqueous solution, and the lower parts of the cut cuttings are soaked into arooting powder liquid for a period of time; the cuttings are inserted into the seedbed, after cutting is performed, watering is immediately and thoroughly performed, an arched greenhouse is preparedabove the seedbed, a plastic film covers the arched greenhouse, and the plastic film is covered by a sunshade net; mist spraying is performed for replenishing water and moisturizing, mist spraying isstopped at night and rainy days, a urea solution and a Hoagland nutrient solution are alternately sprayed once every few days, and carbendazim is sprayed; and after seedling selection is performed, seedlings can be moved out from the greenhouse to enter a seedling raising nursery. The method disclosed by the invention has the beneficial effects that rooting is early and a first-stage finished-product seedling rate is high.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and relates to a method for promoting the rooting of green branch cuttings of garden plants. Background technique [0002] Green branch cuttings of garden plants are also called tender branch cuttings and soft branch cuttings. It uses semi-lignified green branches as cuttings for cutting seedlings. Because the auxin content in the shoots is high, the tissues are tender, the meristems are active, and the terminal buds and leaves have the effect of synthesizing auxin, which can promote the production of callus. And rooting, easy to survive. Green branch cuttings are generally carried out from June to September. The current cutting method is suitable for some garden plants that are easy to root, but some garden plants that are not easy to root have a low rooting rate, a low rate of first-grade finished seedlings, poor quality seedlings, and poor implementation efficiency. Low. Contents...
