Breeding methods and matters needing attention of Parthenocissus officinalis

Parthenocissus is a very adaptable plant that is not afraid of strong light, cold, drought and barren, but it is afraid of stagnant water. The difficulty of raising this plant is very low, and Parthenocissus is highly resistant to harmful gases such as sulfur dioxide. But do you know anything about the breeding of Parthenocissus? The editor will give you a detailed introduction to the two breeding methods of Parthenocissus and points for attention.

When you face a clod of plants? The easiest way to get your cuttings root is to start this spring, when most plants want to grow the fastest. The stems of ivy in spring are soft and more flexible than in autumn, making it more difficult to be Woody and root.

I. points for attention in breeding Parthenocissus

Looking for root causes in spring is flexible and growing. Clip the long stem, look for the place, 5 or 6 nodes (pimple) end. Shaving piece continuous rod in use you have used alcohol mat to kill any bacteria that may be carried. Parthenocissus spreads more patience. First of all, the planting machine or other container drainage hole. Fill the container with clean sand and blast it with water until it is wet.

Break the leaf at the bottom half of the cut, leaving the remaining 2 or 3 pairs of tips. Cut the end into a pile of rooting hormone powder. Put the creeper cuttings into the hole in the wet sand and poke a hole. Gently putt the sand around it until it is firm. Add more cuttings to the pan until it is filled, leaving them 2 inches apart. Put the pot into a plastic bag to open the face up. The top of the sealed bag is loose with a twisted tie or rubber band. Put the bag on a set of heating pads low, in a bright spot away from direct sunlight. Open the bag, keep the fog sand moist every day, and then seal the bag to keep moisture. Check the roots for about 6 weeks after gently pulling the plant. Refueling takes 3 months, so don't think you failed if it didn't happen. Rooted cuttings were transplanted to potted soil 4 months later, and grew indoors a year before they were transplanted outside.

2. Cutting propagation

1. Selection of cuttings: semi-lignified twigs were collected by softwood cuttings from June to July every year, cut into cuttings with 10~15cm length, the upper cut was cut flat to the bud 1cm, and the lower cut to the bud was 0. 5cm oblique shears and hardwood cuttings were selected with a diameter of 0 before soil freezing after defoliation every year. 5cm left and right, long 10~15cm dormant branches, panicle cutting method is the same as tender wood cuttings.

2. Cutting treatment: before cutting, the cuttings were pretreated with ABT1 rooting powder solution. The treatment concentration of tender cuttings was 50 × 10 ~ (- 6) and the soaking time was 0. The concentration of hardwood cuttings was 100 × 10 ~ 6, and the soaking time was 1 ~ 2 hours. The soaking depth is 3~4cm from the cutting mouth under the cuttings.

3. Cutting: using river sand or the mixture of river sand and soil (soil / sand = 1 ∶ 1) as cutting medium, fully leveling. The treated cuttings were directly inserted into the substrate 3~4cm, compacted, sprayed and irrigated in time to keep the matrix and cuttings moist. The cuttings can take root 20-25 days after cutting, and can be transplanted after rooting.

3. Striping propagation

The strip propagation method is a propagation method in which the stems and vines of Parthenocissus are pressed into the soil under the condition that the stems and vines are not separated from the mother, so that the stem nodes in the soil are rooted, and then cut to form several new plants independent of the mother. Before the striping takes root, all the water and nutrients needed for the stem and vine are provided by the mother plant. The advantages of this method are high survival rate, simple management and exuberant seedling growth. The disadvantage is that the reproduction rate is relatively low.

The main results are as follows: 1. Striping period: all stages of growth can be carried out, generally, the sap of Parthenocissus parthenocissus begins to flow from March to April and the striping effect is better when the branches are mature from July to August. Although the pressing strip can survive in other periods, it takes root slowly.

2. Striping method: the stems and vines creeping on the ground can be embedded into the matrix except the exposed growth section where 40~60cm is retained at the base. Matrix composition: high quality barnyard manure ∶ sawdust ∶ topsoil is 1 ∶ 1 ∶ 1 or 2 ∶ 1 ∶ 1. The thickness of matrix covering is generally 15~20cm. After covering, it should be often watered and kept moist to facilitate root and budding.

3. Cut and cut into seedlings: after pressing for 15 days, the new buds can grow from the buried nodes. By the time the new buds reached 40~50cm, the new roots had grown well. At this time, a small section of soil ridge can be dug up at the 10~15cm under the new bud, cut at the internodes, and a new seedling can be obtained. Cover the cut immediately after cutting, so that the cut can heal as soon as possible. After 3 days and 4 days, the new seedlings can be moved out of the nursery, planted or retained in situ to continue to grow.

The place where we can most often see ivy is some schools, of course, there are also a small part of the outer walls of the community will also have ivy, if you have your own garden, you might as well consider planting some ivy, there is also another scenery.

Detailed introduction of matters needing attention and methods of breeding Parthenocissus

Parthenocissus Parthenocissus is a common plant often used in family courtyard and garden decoration. It has strong reproductive ability and is loved by many flower friends. So, do you know what methods and matters needing attention are there in the planting and daily maintenance of wall-climbing tiger? Today, the editor will introduce the relevant knowledge to you in detail.

Parthenocissus can be planted on the shady and sunny side, while in cold areas it is mostly planted in the sunny zone. Parthenocissus has a strong resistance to harmful gases, so it is very suitable for cultivation in industrial and mining areas with serious air pollution. Extensive management can be carried out after growing up for a year, and it can endure a low temperature of minus 20 degrees in winter in the north, and there is no need for cold protection.

Transplanting or planting can be carried out in the deciduous stage, and before planting, it is necessary to apply appropriate organic fertilizer as its base fertilizer, and to cut off the overlong stem and water it, so that it can easily survive. The height of one-year-old seedlings can reach one meter. When planting at the side of the house, building wall or courtyard wall, you should dig a hole 50 centimeters away from the wall base, and the plant distance should generally be 1.5 meters. The balcony of the building can be potted, the seedling pot is close to the wall, and the branches quickly absorb the wall.

The adaptability of Parthenocissus is very strong, the sex also likes the shady and humid environment, but is not afraid of strong light, can be very cold and drought tolerant and barren, the climate adaptability is very extensive, can also maintain the semi-evergreen or evergreen state in the winter south of the warm temperate zone. It is resistant to pruning but afraid of stagnant water, does not have strict requirements on the soil, and can thrive in wet or sunny places, but it will be better to grow in wet and fertile soil. Parthenocissus has strong resistance to harmful gases such as sulfur dioxide and hydrogen chloride, and also has the ability to adsorb dust in the air.

That's all I know about Parthenocissus today. I hope it will be helpful for you to read this article. If you want to know more about Parthenocissus, please continue to pay attention to the succulent flower bed, we will provide you with more related knowledge!
