Embodiment 1

[0027] Embodiments of the present invention provide a kind of method for high-efficiency cutting propagation of plants, comprising the following steps:

[0028] S1. Cutting strip preparation, spray foliar fertilizer, 100 insecticide insecticide and thiophanate-methyl on the plants for surface disinfection treatment 2 days before cutting to improve the activity of cutting branches. The next morning, cut vigorously growing, disease-free and robust semi-hardened or softened branches as cutting mother branches, cut them into branches containing one stem node, leave one third of the leaves, and then use carbendazim to soak and disinfect for 30 minutes. Second.

[0029] S2. Adhesive preparation, select viscous red loam that has been sterilized as the adhesive, grind it finely and dry it according to the ratio of adhesive: nutrient solution weight ratio of about 1:0.2, so that the adhesive can easily adhere to the cutting branches At the stem node, prepare an adhesive. The nutrient...

Embodiment 2

[0034] S1. Preparation of cuttings

[0035] One day before cutting, spray foliar fertilizer, beta-cypermethrin insecticide and carbendazim fungicide on the tomato branches to be branched for surface disinfection to improve the activity of cutting branches. The next morning, cut vigorously growing, disease-free and robust semi-hardened or softened branches as cutting mother branches, cut them into branches containing one stem node, cut off the petiole, and then use carbendazim to soak and disinfect for 30 seconds.

[0036] S2. Adhesive preparation

[0037] Choose viscous sticky soil that has been sterilized as a sticky substance, dry and finely mix it according to the weight ratio of sticky substance: nutrient solution of about 1:0.2, so that the sticky substance can easily adhere to the stem nodes of tomato cutting branches , prepared as an adhesive. The nutrient solution contains MS medium nutrient solution (MgSO 4 ·7H 2 O 185mg / L, CaCl 2 2H 2 O 220mg / L, KNO 3 950mg / L,...

Abstract

The invention discloses an efficient cutting propagation method for plants, and belongs to the technical field of agricultural production. The efficient cutting propagation method is suitable for theplants including branch type plants with stalks and plants with stem buds, such as tomatoes, oranges, trichosanthes kirilowii maxim and other agricultural crops, and comprises the following steps of S1, preparing cutting strips; S2, preparing an adhesive; S3, conducting cutting wood treatment; S4, controlling an aeroponic cultivation environment; and S5, transplanting the cutting strips. Accordingto the method, the advantages of the aeroponic cultivation technology are comprehensively utilized, hormone support is uninterruptedly provided, humidity, air, nutrients, rooting support and requiredhormone conditions required by plant rooting induction and root growth are provided, the rooting rate of the plants is increased, the operation method is simple, and large-scale plant culture is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a method for efficient cutting propagation of plants. Background technique [0002] Cutting is the main way of plant reproduction, it can quickly reproduce plants with the same traits as the female parent in a short period of time, it is widely used in fruit trees, vegetables, Chinese medicinal materials and other crops, and has a broad application market, but the survival rate has always been a problem for cuttings Constraints to large-scale application of technology in plants. The cutting technology is generally to insert the branches into the soil to let the branches grow root buds, which are easily affected by soil factors, such as soil-borne diseases, poor water permeability and air permeability, which cause microbial growth and cause rotten seedlings and roots, which seriously affect the survival rate of plant cuttings. Especially for some vine-...
