Abstract

The invention relates to a cutting and seedling growing method for sweet osmanthus comprising following steps: in the late March, healthy sweet osmanthus seedlings are selected for cutting, the length of each cutting branch is 12 to 15 cm; 3 to 5 days before cutting branches, root irrigation is performed once on mother trees with potassium dihydrogen phosphate with mass fraction of 0.8%; 2 days before cutting branches, lime sulfur 800 times solution is sprayed on branches once; (2) the cut branches are embedded with plant ash having water content of 60 to 65%, and stored under 18 to 22 DEG C for 22 to 36 hours; (3) the cutting branches processed in step (2) are soaked in treating fluid for 25 to 30 min, and then cutting planting is performed. By means of the cutting and seedling growing method for sweet osmanthus, the seedling growing survival rate is about 96% and the economic value of cutting and seedling growing for sweet osmanthus is substantially increased.

Description

A kind of cuttage and seedling culture method of sweet osmanthus

Technical field

The invention belongs to afforestation field is and in particular to a kind of cuttage and seedling culture method of sweet osmanthus.

Background technology

Sweet osmanthus chain timbers Rhinocerotidae evergreen shrubs or dungarunga, matter heavily fortified point thin skin, leaf oblong face end point, opposite, do not wither through the winter. Between peanut leaf internal organs, corolla sympetalous four splits, and shape is little, and its garden-variety is various, and most representational have gold osmanthus, silver osmanthus, orange osmanthus, bay Deng.

Sweet osmanthus is one of big famous flower of Chinese tradition ten, integrate greening, beautification, sweetening treatment view and admire with practicality have both excellent Good Landscape Tree Species, sweet osmanthus clearly can dust-tight, dense can be far excessive, rate as an unsurpassed one.In especially time midautumn, Cong Gui is in full bloom, night quiet wheel circle Border, reward osmanthus of filling a wine cup for, Chen Xiang assails the nostrils, Bracing.Chanting in colored poem in ancient Chinese, chants the quantity of Gui Zhizuo also rather Considerable.Just deeply liked by Chinese from ancient times, be considered traditional famous flower.

With sweet osmanthus do raw material making osmanthus flower tea be special product of China tea, its soft aroma and, delicious taste, by masses liked Love.Sweet osmanthus is commonly employed in gardens construction.

When sweet osmanthus is planted and breeds now, generally use cuttage and bred, but now using cuttage nursery When, in order that the survival rate of cuttage is higher, needs to be processed using auxin, root element etc., time length, easily cause ring Border is polluted, and also easily causes sweet osmanthus to make a variation, the quality of impact sweet osmanthus.

Content of the invention

It is an object of the invention to provide a kind of cuttage and seedling culture method of sweet osmanthus it is not necessary to carry out process using auxin can To reach very high survival rate, environment is not also polluted.

The present invention is achieved through the following technical solutions：

A kind of cuttage and seedling culture method of sweet osmanthus, comprises the following steps：

（1）, late March, select health sweet osmanthus branch carry out cuttage, every segment cuttage branch length be 12-15cm, intercept skewer Transplant 3-5 days before bar, first by elite stand use quality fraction be 0.8% potassium dihydrogen phosphate pouring root once, intercepting cuttage branch First 2 days of bar, sprays 800 times of liquid of a lime sulfur in branch；

（2）, by the cuttage having intercepted branch use water content be 60-65% plant ash embedding, at 18-22 DEG C preserve 22- 36h；

（3）, by step（2）The cuttage branch handled well uses treatment fluid immersion treatment 25-30min, then carries out cuttage plantation, Described soak is made up of following component by weight：Section section grass juice factor 3-5 part, cat grass juice factor 15-18 part, bashfully fruit juice 1-2 part, Ammonium dihydrogen phosphate 0.3-0.5 part.

In step（2）In plant ash in the also alum containing plant ash weight 0.02%, plant ash weight 0.05% Ferrous sulfate, the trbasic zinc phosphate of plant ash weight 0.08%.

Described soak is made up of following component by weight：Section 4.2 parts of grass juice factor of section, 16 parts of cat grass juice factor, bashfully fruit juice 1.6 parts, 0.42 part of ammonium dihydrogen phosphate.

Quick lime in described lime sulfur, sulphur, the weight of water are than for 1：2.5：15.

Described section section grass juice factor is the juice that fresh Drilgrass squeezes, and cat grass juice factor is the juice that fresh cat grass squeezes, bashfully Fruit juice is the fresh juice bashfully really squeezing.

Beneficial effects of the present invention：The present invention provide sweet osmanthus cuttage and seedling culture method intercept cutting before, first using phosphorus Acid dihydride potassium solution processes elite stand, and is sprayed using the lime sulfur through preparing, and it is right after intercepting cutting to be prevented effectively from The negative effect that sweet osmanthus elite stand is caused, increases the nutrient content storage in branch, the survival rate of lifting cuttage branch cutting.

After intercepting cuttage branch, using the plant ash embedding treatment processing, change the mode in the past using sandy soil to process, The survival rate of cuttage branch can be lifted further, the present invention is processed using the treatment fluid that plant component is made, and changes tradition Method uses the method that the steroids inorganic agent such as gibberellin is processed, low cost, pollution-free it is also possible to be obviously improved sweet osmanthus cuttage Survival rate.

Empirical tests, the present invention provide sweet osmanthus cuttage and seedling culture method nursery survival rate 96% about hence it is evident that improving osmanthus The economic worth of flower cuttage and seedling culture.

Specific embodiment

Embodiment 1

（1）, late March, select health sweet osmanthus branch carry out cuttage, every segment cuttage branch length be 12cm, intercept cuttage 3-5 days before branch, first by elite stand use quality fraction be 0.8% potassium dihydrogen phosphate pouring root once, intercept cuttage branch First 2 days, spray 800 times of liquid of a lime sulfur in branch；

（2）, by the cuttage having intercepted branch use water content be 62-65% plant ash embedding, also contain plant ash in plant ash The alum of weight 0.02%, the ferrous sulfate of plant ash weight 0.05%, the trbasic zinc phosphate of plant ash weight 0.08%, at 20 DEG C Lower preservation 28h；
