Technical Field

[0001] The invention relates to the technical field of kiwifruit cultivation, and more particularly to a method for promoting early cultivation of kiwifruit by raising seedlings in containers. Background Art

[0002] As a fruit with high nutritional value and rich in vitamin C, kiwifruit has become one of the mainstream consumer fruits in the world with a rapid growth in cultivation area and output worldwide. In China, the scale of the kiwifruit industry has been growing year by year, with an average annual growth rate of 22.14%. Among them, the scale of the kiwifruit industry in Shaanxi, Sichuan, Guizhou, Hunan, Jiangxi and Henan ranks among the top in the country. With the growth of kiwifruit consumption demand, especially the rising demand for high-quality kiwifruit, online consumption and online sales have gradually become the main channels of the kiwifruit market.

[0003] In the cultivation technology of kiwifruit, seedling cultivation is a key link, which directly affects the yield and quality of kiwifruit. The traditional kiwifruit seedling cultivation method mainly adopts open field cultivation, including sowing, grafting, cutting, layering and tissue culture. However, these methods have some limitations, such as low survival rate and poor growth, and do not include early cultivation and drug induction of the scion buds, resulting in a long growth cycle of kiwifruit seedlings and a low rate of high-quality seedlings.

[0004] Therefore, the present invention aims to provide a method for promoting early cultivation of kiwifruit in container seedlings. By using container seedlings in red soil cultivation areas, a unique red soil-based formula matrix, combined with greenhouse insulation and 1.2% monocyanamide treatment, the early germination of kiwifruit scions can be effectively promoted, and the high-quality seedling rate of kiwifruit one-year seedlings can be significantly improved. Summary of the invention

[0005] The purpose of the present invention is to provide a method for early cultivation of kiwifruit seedlings in containers. The present invention can effectively promote early germination of kiwifruit scions by using a formula matrix based on Jiangxi's unique red soil, combined with greenhouse insulation and 1.2% monocyanamide treatment, and significantly improve the high-quality seedling rate of kiwifruit one-year seedlings.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A method for early cultivation of kiwifruit seedlings in containers, comprising the following steps:

[0007] S1. Mix Jiangxi red soil, organic fertilizer, peat, rice husk, perlite and vermiculite in specific proportions to form a matrix suitable for kiwifruit growth;

[0008] S2, soaking the scion of the grafted kiwifruit seedling in 1.2% cyanamide solution, and taking it out after treating for a certain period of time;

[0009] S3, placing the treated scion in a heat preservation shed, controlling the temperature in the shed, and promoting early germination of the scion;

[0010] S4. After the scion sprouts, carry out routine seedling management until the kiwifruit seedlings reach the standards of high-quality seedlings.

[0011] The present invention is further configured as follows: the volume ratio of the components in the matrix is ​​Jiangxi red soil: organic fertilizer: peat: rice husk: perlite: vermiculite = 7:5:1:1:1:1.

[0012] The present invention is further configured as follows: the treatment time of the cyanamide is 5 minutes, and the treatment concentration is 1.2%.

[0013] The present invention is further configured as follows: the temperature inside the heat preservation shed is 20° C. and the humidity is above 65%.

[0014] The present invention is further configured as follows: the screening criteria for the high-quality seedlings are a diameter greater than 0.7 cm and a plant height greater than 1.8 m.

[0015] The present invention is further configured as follows: the seedling management includes watering, fertilizing and pest and disease prevention and control seedling management after the scion sprouts.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The present invention mixes Jiangxi red soil, organic fertilizer, peat, perlite and vermiculite in a specific ratio to prepare a kiwifruit container seedling medium suitable for red soil cultivation areas, thereby improving the limitations of traditional seedling raising methods;

[0018] 2. The present invention uses chemical treatment and greenhouse insulation technology to advance the germination time of kiwifruit scions by 7-10 days compared with the common method. The high-quality seedling rate of kiwifruit before July is increased by more than 30% compared with the ordinary container seedling cultivation, which significantly improves the germination time and high-quality seedling rate of kiwifruit scions and shortens the growth cycle.

[0019] 3. The one-year high-quality seedling rate of the present invention is increased by more than 30% compared with ordinary open-field seedling cultivation, which effectively improves the high-quality seedling rate of one-year kiwifruit seedlings and provides technical support for high-yield and high-quality cultivation of kiwifruit.
