Problems solved by technology

[0004] The conventional method of raising guava seedlings is grafting, but the grafting method has a long cycle and low efficiency, and the results do have certain variability
The prior art also has the method of adopting cuttings to grow seedlings, but the cutting conditions and environment of guava are not easy to control, resulting in unstable survival rate

Embodiment 1

[0022] The invention relates to a guava hydroponic cutting propagation method, which selects semi-lignified guava shoots that grow vigorously, have good buds, and are disease-free, and trim them into 8-10 cm double-leaf and double-bud branches as cuttings, and cut the lower part of the cuttings into an inclined plane , Submerged 2 cm of the base of the cuttings into 60 mg / kg ABT2 rooting powder solution and soaked for 60 min, then took it out and dried it for later use.

[0023] The preparation of the nutrient solution: the raw material content of the nutrient solution is: 1 / 2MS+IBAO0.4mg / L+GGR1.0mg / L+PG30mg / L+sucrose 10g / L+agar 2.0g / L+activated carbon 1.0g / L, add citric acid solution to adjust the pH of the nutrient solution to 5.8.

[0024] Before cutting, choose a box made of glass as the cutting container in the cutting room. The cutting box is 20cm wide, 50cm long, 20cm deep, and the glass is 0.5cm thick; pour nutrient solution into the cutting container, and the depth of...

Embodiment 2

[0026] A guava hydroponic cutting propagation method, selects semi-lignified guava shoots that grow vigorously, have good buds, and are disease-free, and trim them into 8-10cm double-leaf and double-bud branches as cuttings, and cut the lower part of the cuttings into an inclined plane , Submerge the base 3cm of the cuttings into 60mg / kg ABT2 rooting powder solution and soak for 80min, then take it out and dry it for later use.

[0027] The preparation of the nutrient solution: the raw material content of the nutrient solution is: 1 / 2MS+IBAO0.8mg / L+GGR1.5mg / L+PG40mg / L+sucrose 10g / L+agar 3.0g / L+activated carbon 2.0g / L, add citric acid solution to adjust the pH of the nutrient solution to 6.0.

[0028] Before cutting, choose a box made of glass as the cutting container in the cutting room. The cutting box is 25cm wide, 55cm long, 20cm deep, and the glass is 0.5cm thick; pour the nutrient solution into the cutting container, and the depth of the nutrient solution is 3-5cm and cu...

Embodiment 3

[0030] A kind of guava hydroponic cutting propagation method, selects the fresh shoot of guava that grows vigorously, has good buds, and is disease-free, and prunes the branches with double leaves and double buds of 8-10cm as cuttings, and cuts the lower part of the cuttings into an inclined plane, Soak 4 cm of the base of the cuttings in 60 mg / kg ABT2 rooting powder solution for 80 minutes, then take it out and dry it for later use.

[0031] The preparation of the nutrient solution: the raw material content of the nutrient solution is: 1 / 2MS+IBAO1.2mg / L+GGR2.0mg / L+PG40mg / L+sucrose 10g / L+agar 4.0g / L+activated carbon 1.5g / L, add citric acid solution to adjust the pH of the nutrient solution to 5.9.

[0032] Before cutting, choose a box made of glass as the cutting container in the cutting room. The cutting box is 30cm wide, 60cm long, 25cm deep, and the glass is 0.5cm thick; pour the nutrient solution into the cutting container, and the depth of the nutrient solution is 3-5cm ...

Abstract

The invention discloses a guava water culture cutting propagation method. The method is characterized in that the method comprises the steps of cutting shoot acquisition and treatment, nutrient solution preparation, cuttage container preparation, water culture, after-cuttage management, and acclimatization and transplantation; current-year semi-lignified or lignified robust young guava sprouts which are in good condition and free of disease are selected, trimmed and inserted in a cuttage container containing a nutrient solution for water culture, culture conditions are controlled, acclimatization and transplantation are conducted after cutting shoots with radicles are obtained, and then guava nursery stock is obtained. By the adoption of the method, the problem that cuttage is limited by season is solved, cutting propagation can be conducted throughout the year, culture period is short, rooting speed is high, environment controllability is high, culture conditions are stable, and the survival rate of cutting shoots is over 93%. The method is suitable for large-scale production, can be widely popularized, and can generate great economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention belongs to the field of plant cutting propagation and relates to the cutting propagation of guava, in particular to a guava hydroponic cutting propagation method. Background technique [0002] Guava, (PsidiumguajavaLinn.) belongs to the evergreen small tree of Myrtaceae, 2-5m high. Guava is a very adaptable tropical fruit tree. It is native to tropical America and spread to tropical and subtropical regions of the world in the 16th to 17th centuries, such as North America, Oceania, New Zealand, Pacific Islands, Indonesia, India, Malaysia, North Africa, Vietnam, etc. It was introduced into my country at the end of the 17th century. Existing Taiwan, Guangdong, Guangxi, Fujian, Jiangxi and other provinces are all cultivated, and some places have become wild fruit trees. [0003] Guava likes light, likes warmth, is not cold-resistant, and likes fertile, well-drained soil; guava can be grown by seedlings, aerial layering and grafting, or by ...
