Embodiment 1

[0022] The method for raising seedlings by cuttings of golden leaf crossing yellow twigs comprises the following steps:

[0023] 1. Cutting time: late April to the end of June

[0024] 2. Preparation of rooting agent: dissolve 400mg of indolebutyric acid (IBA) and 400mg of naphthaleneacetic acid (NAA) in 100ml of ethanol with a volume concentration of 95%, add water to 1kg and mix evenly, then add vitamin B 1 2g, spare;

[0025] 3. Equipped with cutting substrate: mix perlite, vermiculite and peat at a volume ratio of 1:1:1 to make a cutting substrate, dilute 1000 times with 50% carbendazim wettable powder by mass, spray and disinfect the cutting substrate, and mix the base evenly;

[0026] 4. Prepare cuttings: select the upper branches of the current year from the female parent plant that grows robustly and is free from diseases and insect pests. It is required that there are 2 buds on it. The buds should be full, free from defects and pests, and keep 1 to 2 leaves at the t...

[0034] 3. Prepare the cutting substrate: mix perlite, vermiculite and peat at a volume ratio of 2:1:1 to make the cutting substrate, dilute 1500 times with 60% carbendazim wettable powder by mass and spray to disinfect the cuttings base, and mix the base evenly;

[0035] 4. Preparation of cuttings: Select the upper branches of the current year from the female parent plant that grows robustly and has no pests and diseases. It is required that there are 4 buds on it. The buds should be full, free of defects, and free of pests and diseases, and keep 1 to ...

Embodiment 3

[0040] The method for raising seedlings by cuttings of golden leaf crossing yellow twigs comprises the following steps:

[0041] 1. Cutting time: late April to the end of June

[0042] 2. Prepare rooting agent: dissolve 450mg indolebutyric acid (IBA) and 450mg naphthaleneacetic acid (NAA) in 100ml volume concentration 95% ethanol first, add water to 1kg and mix evenly, then add vitamin B 1 2.1g, spare;

[0043]3. Prepare the cutting substrate: mix perlite, vermiculite and peat at a volume ratio of 1.5:1:1 to make the cutting substrate, dilute 1200 times with 55% carbendazim wettable powder by mass and spray to disinfect the cuttings base, and mix the base evenly;

[0044] 4. Preparation of cuttings: Select the upper branches of the current year from the female parent plant that grows robustly and has no pests and diseases. It is required that there are 3 buds on it. The buds should be full, not incomplete, and free from pests and diseases, and keep 1 to 2 leaves at the top; ...

Abstract

The invention discloses a Lysimachia nummularia softwood cuttage seedling-raising method. According to the Lysimachia nummularia softwood cuttage seedling-raising method, the cuttage rooting rate can reach above 95%, the survival rate can reach above 98% after transplanting, and the time from scion selection to transplanting surviving is 150-180 days. The method is simple in technical operation, is high in reproduction efficiency, can achieve reproduction and seedling acquisition in the same year, and has import application value in seedling vegetative propagation production of Lysimachia nummularia fine ornamental colorful leaf ground cover plant.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings of twigs of golden leaf guoluhuang, and belongs to the technical field of cultivation and planting of goldenye guoluhuang. Background technique [0002] Golden Leaf Guoluhuang is a perennial herbaceous plant of the genus Guoluhuang in Primulaceae. It has abundant stolons on the surface, short stem nodes, and can take root on the ground between nodes; the leaves are oval and golden yellow, and have high ornamental value. , is a rare colorful leaf ground cover resistant to extensive management. It has a long growth period and a long green duration. It can grow flat and prostrate, and has a strong ability to spread and expand. The plants are extremely dense and lie neatly. Because of its strong resistance to extensive management, drought resistance, cold resistance, and heat resistance, the demand for Golden Leaf Guolu Huang in the greening industry at home and abroad has become increasi...
