Problems solved by technology

Cuttings can be divided into soft branch cuttings and hard branch cuttings. Young branches have active meristems and are relatively easier to survive, but have poor weather resistance and require strict management. Hard branches are just the opposite. The two methods of cutting research are not systematic, resulting in low rooting rate, easy to get sick, low seedling rate, long seedling breeding cycle, complicated management and high cost of breeding

Embodiment 1

[0034] A kind of fast seedling raising method of eucalyptus hard branch cutting, comprises the steps:

[0035] (1) Preparation of cuttings:

[0036] After the leaves of the trees fall in late autumn, select the 3-year-old Luan tree, cut off the branches with a diameter of 1~1.2cm in the current year as cuttings, and then cut them into sections with a length of 12cm. The upper cut is flat and the lower cut is oblique , to ensure that the cut is smooth and made into cuttings for later use;

[0037] (2) Winter storage in wet sand:

[0038] Take the cuttings prepared in step (1) as a bundle of 35, bury them in the wet sand, and control the relative water content of the wet sand to be 65-70%;

[0039] (3) Preparation of cuttings treatment solution:

[0040] Take the material of corresponding weight portion and make cuttings treatment liquid, each component of described cuttings treatment liquid and corresponding weight percent are as follows:

[0041] Potassium permanganate 0.8...

Embodiment 2

[0062] A kind of fast seedling raising method of eucalyptus hard branch cutting, comprises the steps:

[0063] (1) Preparation of cuttings:

[0064] After the leaves of the trees fall in late autumn, select 2-year-old eucalyptus trees, cut off branches with a diameter of 1.2 to 1.5 cm in diameter as cuttings, and then cut them into sections with a length of 15 cm. The upper cut is cut flat, and the lower cut is cut obliquely , to ensure that the cut is smooth and made into cuttings for later use;

[0065] (2) Winter storage in wet sand:

[0066] Take 40 cuttings prepared in step (1) as a bundle, bury them in the wet sand, and control the relative water content of the wet sand to 65-70%;

[0067] (3) Preparation of cuttings treatment solution:

[0068] Take the material of corresponding weight portion and make cuttings treatment liquid, each component of described cuttings treatment liquid and corresponding weight percent are as follows:

[0069] Potassium permanganate 1%, ...

Abstract

The invention discloses a koelreuteria paniculata hardwood cutting quick-seedling method and belongs to the field of planting. The method includes the specific steps of (1), preparing cuttings, (2), burying the cuttings in wet sand in winter, (3), preparing treating fluid of the cuttings, (4), treating the cuttings, (5), preparing cutting medium, (6), carrying out cuttage, and (7) managing after cuttage. The operating steps of the method are in reasonable arrangement, and by the method, the survival rate of the cultured cuttings is equal to or even higher than 98%, constitution and property of the cuttings are improved effectively, management cost is lowered, and as compared with the conventional method, the cost for culturing the cuttings is decreased by 25-35% and the seedling cycle is shortened by 40-60%; besides, the cultured cutting seedlings grow well and have strong root systems and high economic benefit.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for rapidly growing seedlings of eucalyptus hard branch cuttings. Background technique [0002] Eucalyptus is a Sapindaceae plant belonging to the genus Euania. It is resistant to drought and barrenness, and has strong adaptability to the environment. The seeds can be used to extract industrial oil. The eucalyptus tree is dignified and neat, and its leaves, flowers, and fruits are all available for viewing. It is also highly resistant to wind, dust pollution, sulfur dioxide, and ozone. It is especially suitable for greening urban avenues and sidewalks. [0003] Eucalyptus can be raised by sowing and cutting. Cutting propagation has the characteristics of high survival rate, short seedling time, strong root system and strong stress resistance, so it is widely used. Cuttings can be divided into soft branch cuttings and hard branch cuttings. Young branches have active m...
