Abstract

A method for propagating Jinpingteng, which consists of selecting strong, mature or half-matured side vines of Jinpingteng with full bud eyes, taking 2-3 nodes in the middle of the side twigs of Jinpingteng as cuttings, and keeping half of the top of the cuttings. Open the leaves, and remove all the other leaves; then rinse the base of the cuttings with clear water, soak them in a 0.5% carbendazim solution for disinfection for 5 minutes; then dilute them 4000 times with Guoguang rooting agent, and soak them for 3 minutes for rooting pretreatment; The cuttings are cut in the bed matrix, drenched with water to keep it moist, and cultivated in the shade. The temperature of the cultivation environment is controlled at 15-20°C and the humidity is 60%-70%. The method of the present invention is used for cuttings, and the survival rate can be as high as 100%. After the cuttings, the plants take root quickly, and can take root in about 7 days in spring (temperature); the plants grow relatively robustly, and the color is dark green. Compared with hydroponics and layering, this method is practical and economical. For example, hydroponics needs to purchase nutrient solution, and the cost of management and maintenance is relatively high.

Description

A kind of method for rapid breeding of Jinping vine

technical field

The invention relates to a plant breeding method, in particular to a Jinping vine breeding method.

Background technique

Jinping vine (Cissus sicyoides 'Ovata'), native to tropical America, is a perennial evergreen vine belonging to the family Vitis. Branches are slender, with tendrils; leaves alternate, long heart-shaped, with serrated leaf margins; summer and autumn flowers, pale green and white, black when ripe. Its characteristic is that the adult plant can grow reddish-brown slender aerial roots from the stem nodes. If it is placed on a scaffold, the entire aerial root has different colors from top to bottom. Hundreds or thousands of them hang under the scaffold like a scene. Natural curtains. The plant has strong spreading ability and the ornamental value of the root system is very high. It is a good material for green corridors, green walls or garden landscaping. For example, in the Neiwan Scenic Area of Hsinchu, Taiwan, many hotels use Jinping rattan as natural curtains. It is a vine-like ornamental plant resource that has characteristics, needs research, and can be developed. At present, there are few research reports on Jinpingteng at home and abroad, and it is limited to morphological characteristics, cultivation and management techniques, etc., and there is basically no research on reproduction techniques.

Contents of the invention

The object of the present invention is to provide a method for propagating Jinpingteng, the seedlings obtained by the propagating method have a high survival rate and strong plants.

The object of the invention is achieved through the following technical solutions:

A kind of propagation method of Jinpingvine, is characterized in that: select strong and mature or semi-ripe Jinpingvine side vines with full bud eyes, take 2-3 nodes in the middle of the Jinpingvine side vines as cuttings, said Keep half of the leaves on the top of the cuttings, and remove all the remaining leaves; then rinse the base of the cuttings with clean water, soak in a 0.5% carbendazim solution for disinfection for 5 minutes; then dilute it 4000 times with Guoguang root-growing powder to reach 50mg/L Soak for 3 minutes for rooting pretreatment; finally put the cuttings in the bed matrix, drenched with water to keep it moist, and carry out shading cultivation, control the cultivation environment temperature at 15-20°C, and humidity at 60%-70%.

In order to further promote the cutting seedlings to be more robust and improve their survival rate, the above-mentioned bed matrix is to add humus and quicklime in the garden soil as the cutting matrix, and the amount of humus added is 5kg of humus per square meter of soil. The amount of soil and quicklime added is 0.15 kg per square meter of soil; the cutting bed width of the cutting substrate is controlled at 1 meter, the height is controlled at 25 cm, and the length can be determined with the cutting scale.

The present invention has following beneficial effect:

The method of the present invention is used for cutting, and the survival rate can be as high as 100%. After the cutting, the plant takes root quickly, and can take root in about 7 days in spring (temperature); the plant grows relatively robustly, and the color is dark green. Compared with hydroponics and layering, this method is practical and economical. For example, hydroponics needs to purchase nutrient solution, and the cost of management and maintenance is relatively high.

Detailed ways

In order to express the present invention more clearly, the present invention will be further described below, and the following description is a preferred embodiment of the present invention, and cannot limit the protection scope of the present invention in any way.

Example 1

A kind of propagation method of Jinping rattan, carries out according to the following steps:

1. Preparation of slotting bed: Plow the garden soil in the greenhouse or plastic greenhouse, add 5kg of humus soil per square meter of garden soil, and 0.15kg of quicklime per square meter of garden soil to keep the matrix clean and the particles uniform , Medium size; the cutting substrate bed is 1 meter wide and 25 cm high, and the length depends on the cutting size.

2. Selection of cuttings: In the vigorous growth season, choose the middle part of the side vines that are strong, mature or semi-mature, with full bud eyes, leave 2-3 nodes, cut them into about 10cm as cuttings, keep half of the leaves on the top of the cuttings, and leave the rest All leaves are removed. Rinse the base of the cuttings with clean water, soak them in a 0.5% carbendazim solution for disinfection for 5 minutes, and then dilute them 4000 times with Guoguang Rooting Powder (the active ingredient content is 20%, in terms of mass percentages) to reach 50mg/L (1L solution contains 50mg Guoguang rooting powder), after soaking for 3 minutes for rooting pretreatment, cuttages are placed in the above-mentioned prepared bed, drenched with water to keep it moist, and cultivated in the shade. At 60% to 70%.

3. Comparison of three breeding methods

Select robust, mature or semi-mature side vines with full buds, and select the parts of 0-1m, 1-2m, 2-3m, 3-4m (the junction of the side vines and the main branch is defined as 0m, 0～1m, 1～2m, 2～3m, 3～4m these 4 knots represent the distance of the side branch from the main branch), count as 4 knots, take 6 branches with 2～3 buds in each knot, and carry out hydroponics , Research on the above three propagation methods of cutting and layering. 0-1m and 1-2m Jinpingteng branches have off-white skins, which belong to old branches; 2-3m Jinpingteng branches have yellow-green skins, which are medium-mature; 3-4m branches have tender green skins, which belong to young branches. 4 sections are used as 4 materials, 3 propagation methods are used as 3 treatments, each treatment has 3 repetitions, and 2 branches are guaranteed in each repetition.

Table 1 Comparison of three propagation modes in different parts of Jinpingteng

Remarks: When looking at the roots of cuttings and layering, randomly take 1-2 live branches, carefully peel off the soil, clean up, measure again, and then put them into the soil.

It can be seen from the above table that the three propagation methods are hydroponics > cuttings > layering; but from an economic and management point of view, cuttings > hydroponics > layering. The method of the invention is used for cutting, and the survival rate can be as high as 100%. At the same time, the rooting of the plant after cutting is fast, and it takes about 7 days to take root at 15-20 DEG C. From the appearance, the plant grows vigorously and has a dark green color.
