Problems solved by technology

[0002] Horse chestnut, also known as bodhi tree, is deeply loved by the world because of its tall and magnificent appearance, high appreciation value, and its ecological value of absorbing dust and harmful gases. It has gradually developed into one of the four famous street trees. With the development of the development, the demand for horse chestnut is also increasing. However, at present, horse chestnut is mainly propagated by seed sowing, but it takes a long time (15-20 years) from sowing to flowering and fruiting, and mature horse chestnut The fruit setting rate of Aesculus is low, and the seeds are very easy to lose their reproductive ability. Therefore, the use of seeds for propagation has been greatly restricted, especially causing great difficulties for the promotion of excellent trees. The rooting rate can only reach about 40%, which obviously increases the planting cost

Embodiment 1

[0018] A method for cutting seedlings of horse chestnut trees includes the following steps:

[0019] (1) Selection of cuttings: Choose horse chestnut plants that are 1 to 15 years old and have excellent traits. Three months before cuttings are cut, circumscribe the branches where the cuttings are located. The circumscribed cut is 1.2~1.5m from the top of the shoots. , Flat cut at the upper end and oblique cut at the lower end, each cutting has 2~3 bud eyes, which retain nutrients, after germination, promote photosynthesis, accelerate callus formation, and increase survival rate. In spring February, cut sprouted twigs , 100 cuttings each year, with a length of 20-25cm, get cuttings;

[0020] (2) Cutting treatment: After cutting the cuttings, they are soaked in a soaking solution at a temperature of -9°C for 3 hours, which can not only sterilize, but also enhance the stress resistance of the cuttings, and promote the formation and differentiation of callus. After drying to a moistur...

Embodiment 2

[0045] A method for cutting seedlings of horse chestnut trees includes the following steps:

[0046] (1) Selection of cuttings: Choose horse chestnut plants that are 1 to 15 years old and have excellent traits. Three months before cuttings are cut, circumscribe the branches where the cuttings are located. The circumscribed cut is 1.2~1.5m from the top of the shoots. , Flat cut at the upper end and oblique cut at the lower end. Each cutting has 2 to 3 bud eyes, which retain nutrients. After germination, it promotes photosynthesis, accelerates callus formation, and improves survival rate. In March in spring, cut sprouted twigs , 100 cuttings each year, with a length of 20-25cm, get cuttings;

[0047] (2) Cutting treatment: After cutting the cuttings, they are soaked in a soaking solution at a temperature of -8°C for 3 hours, which can not only sterilize, but also enhance the stress resistance of the cuttings and promote the formation and differentiation of callus. After drying to a ...

Embodiment 3

[0072] A method for cutting seedlings of horse chestnut trees includes the following steps:

[0073] (1) Selection of cuttings: Choose horse chestnut plants that are 1 to 15 years old and have excellent traits. 4 months before cuttings are cut, circumscribe the branches where the cuttings are located. The circumscribed cut is 1.2~1.5m from the top of the shoots. , Flat cut at the upper end, oblique cut at the lower end, each cutting has 2~3 bud eyes, which retain nutrients, after germination, promote photosynthesis, accelerate the formation of callus, and increase the survival rate. In spring April, cut sprouted twigs , 100 cuttings each year, with a length of 20-25cm, get cuttings;

[0074] (2) Cutting treatment: After cutting the cuttings, they are soaked in a soaking solution at a temperature of -7°C for 4 hours, which can not only sterilize, but also enhance the stress resistance of the cuttings and promote the formation and differentiation of callus. After drying to a moistur...

Abstract

The invention mainly relates to the technical field of planting and discloses a seedling-culture cuttage method of aesculus chinensis. The method includes the steps of cutting selection, cutting treating, substrate preparation, cuttage, after-cuttage management, and hardening-seedling transplanting. The method is simple and convenient to operate, the survival time of 6-year-old aesculus chinensis is shortened to 20-25 days, the cutting survival rate is as high as 98%, the efficiency of planting is significantly improved, and the economic income is increased by 24.7%; girdling is conducted on branches before cutting scissoring, nutrients are retained, formation of calluses is accelerated, and the survival rate is improved; cuttings are placed in low-temperature soaking liquid instantly after being cut, the antibacterial effect and the sterilization effect are achieved, the stress resistance of the cuttings can also be enhanced, and formation and differentiation of the calluses are promoted; drying is conducted after soaking, the water absorption and respiration abilities of the cuttings are improved, the photosynthesis is promoted, seedling-culture conditions are gradually regulated after cuttage, the growth of roots and blossom buds is accelerated, energy needed by the aesculus chinensis is provided, the survival of the cuttings is promoted, seedling gradual hardening of seedlings is conducted after rooting, and the survival rate of transplanting reaches 99%.

Description

Technical field [0001] The invention mainly relates to the field of planting technology, in particular to a method for cutting seedlings of horse chestnut trees. Background technique [0002] Horse chestnut, also known as linden tree, is loved by the world because of its tall and magnificent appearance, high appreciation value, and the ecological value of absorbing dust and harmful gases. It has gradually developed into one of the four famous street trees. With the greening business The demand for horse chestnuts is also increasing due to the development of buckeyes. However, horse chestnuts are currently mainly seeded and reproduced, but it takes a long time (15-20 years) from sowing to flowering and fruiting, and adult horse chestnuts The fruit-setting rate is low, and the seeds easily lose the ability to reproduce. Therefore, the use of seed propagation is greatly restricted, especially for the promotion of excellent trees. However, the survival rate of horse chestnut cutting ...
