Embodiment 1

[0014] On the morning of April 21, 2009, two-year-old healthy leaves of Toad leaf begonia were taken, the petioles were cut off, and the leaves were cut into small leaf pieces of 1cm×1cm, and inserted into the sterilized thin-slice vermiculite substrate, which was placed in a disposable plastic cup for cuttings In the container, small holes are pierced with needles on the bottom and side of the plastic cup (for ventilation), and the plastic cup is hung on the wrapping box, which contains 1.0mg / L6-BA, 1.0mg / LNAA, and 1.0mg / L KT's B5 adventitious bud induction nutrient solution, the height of the liquid should be dipped into the nutrient solution at the bottom of the plastic cup. The liquid maintains a certain volume.

[0015] The weekly box is placed under the intermittent spraying of full light, and the time and frequency of spraying are adjusted according to air temperature and light. On May 10, 2009, clustered buds were directly produced on the leaf block, and the different...

Embodiment 2

[0018] Sterilize the flake vermiculite for standby; prepare 1 / 2MS nutrient solution containing 1.0mg / L6-BA, 1.0mg / LNAA, and 1.0mg / L KT for inducing adventitious buds; prepare 1 / 2MS nutrient solution for rooting nutrient solution spare;

[0019] On October 6, 2009, healthy biennial leaves were selected, the petioles were cut off, and the leaves were cut into small leaf pieces of 1 cm×1 cm, which were inserted into the prepared sterilized flake vermiculite substrate. The matrix is ​​packed in a cutting container made of a disposable plastic cup. Small holes (for ventilation) are pricked on the bottom and sides of the plastic cup (for ventilation). The plastic cup is hung on the weekly packing box. -BA, 1.0mg / LNAA, and 1.0mg / L KT 1 / 2MS adventitious bud induction nutrient solution, the height of the liquid should be dipped into the nutrient solution at the bottom of the plastic cup. Check the height of the nutrient solution, and supplement the nutrient solution appropriately ...

Abstract

The invention relates to a new leaf cuttage method for Begonia rex, which comprises the following steps: using sterilized laminar vermiculite as the substrate, and adopting a B5 or 1 / 2MS adventitious bud inducement nutrient solution containing 6-BA of 1 mg / L, KT of 1 mg / L and NAA of 1 mg / L and a 1 / 2MS or 1 / 2MS rooting nutrient solution containing NAA of 0.2 mg / L; in a morning or a cloudy day at the end of spring or in mid autumn, selecting healthy biennial leaves, shearing off leaf stalks, cutting the leaves into leaf pieces, and inserting the leaf pieces in the substrate which is filled in a disposable plastic cup provided with small holes at the bottom and the edge; suspending the plastic cup on a turnover box, wherein the turnover box is filled with the adventitious bud inducement nutrient solution of which the liquid level can reach the bottom of the cup, the adventitious bud inducement nutrient solution should be changed weekly and continually aerated; placing the turnover box under a full exposure intermittent spray to enable the leaf pieces to produce cluster buds; transferring the seedlings into a new cuttage substrate, and replacing the nutrient solution in the turnover box with the rooting nutrient solution to enable the seedlings to root; and transplanting the seedlings when the root length reaches 1 cm, wherein the survival rate can reach 94-97%.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a new method for cutting leaves of toad leaf begonia. Background technique [0002] The propagation methods of Toad Leaf Begonia include seed propagation, division propagation and cutting propagation. Cuttings generally use leaves as propagation materials. The leaf cuttings of Toad Leaf Begonia are divided into whole leaf cuttings and single leaf cuttings. It is better to choose mature biennial leaves. Among them, the whole leaf cuttings use the complete leaves as cuttings, and generally use the horizontal placement method: cut off the main veins on the leaves with a sharp knife, and make 3-5 incisions on each leaf, and then spread the leaves on the cutting bed (pot) surface , and suppress it to make the leaves fully combine with the cutting substrate, spray water until the substrate is moist, about a month, roots will take root at the base of the petiole and the inc...
