Cassava mosaic propagation method introduction

Flower and leaf cassava is a kind of foliage plant which is suitable for indoor cultivation, but it is not difficult to cultivate it artificially. The overwintering temperature of flower and leaf cassava is higher than 15 ℃, so it is necessary to move indoors in winter. Artificial propagation of flower and leaf cassava can be done by cutting and sowing. The editor will introduce to you these two propagation methods of flower and leaf cassava.

Flowered cassava

1. Cutting propagation: it is suitable when the buds on the stem just begin to sprout from April to May in spring. Select sturdy and substantial stems and cut them into cuttings 10 cm long. The milk from the incision should be washed and dried to prevent decay. The temperature of the sand bed for cutting was kept at 20-25 ℃, and it could take root in about 20 days.

2. Sowing and propagation: it can be carried out immediately after seed harvest, otherwise the seed germination rate will be reduced. The mature seeds were sown in the breeding sand bed and kept at 25 ~ 30 ℃ and a certain humidity. Generally, they could germinate in 10 ~ 15 days and transplant in 1 ~ 2 months.

Cultivation and management of flower and leaf cassava (figure)

Scientific name of cassava: Manibotesculentacv.Variegata

Families and genera: Euphorbiaceae, cassava

Alias: variegated cassava

Native to tropical America

Morphological features: erect shrub, about 1.5 meters high, long root, fleshy root. Leaves palmately 3-7-parted, lobes lanceolate, entire, with irregular yellow patches in the center of lobes. Leaves green, petiole red, inflorescences axillary.

Common foliage cultivation species are: shield leaf cassava (M.peltata): leaves shield-shaped, entire, gray-green leaves. Leaf veins protruding, pink.

Habits: like warm and sunny environment, not cold-resistant, afraid of frost, resistant to semi-overcast, cultivation environment should not be too dry or too wet.

Cultivation management: potted flower-leaf cassava, the soil is suitable to use loose, fertile, well-drained slightly acidic soil. The growing period should be fully watered, but the humidity of the basin soil should not be too high, otherwise it will make the roots rot. When the soil is too dry or wet when it is too dry, it can also lead to defoliation. During the dormant period of deciduous leaves in winter, the watering times should be gradually reduced and the basin soil should be kept slightly dry. If in the low temperature and humid cultivation environment, the fleshy root is easy to rot. In the process of cultivation, fertilizer can be applied once a month, and phosphorus and potassium fertilizer should be applied for 2 or 3 times in the peak growth period, so as to avoid the excessive growth of branches and leaves and keep the leaves magnificent.

The suitable temperature for growth is 25: 30 ℃ from March to September, 18: 20 ℃ from September to March, and the overwintering temperature is higher than 15 ℃. If the room temperature is lower than 10 ℃, the plant can stop growing and cause defoliation. Flower and leaf cassava grows rapidly and has strong germinating ability. when the cuttings are 20-25 cm high after potted, they need to be coring to promote their multi-branching. For potted plants, the pots should be changed once a year, and the aboveground branches should be pruned, leaving 3-4 main branches in each pot. Depress the plant type, cut off the twigs and dead branches, so that the plant to maintain a beautiful plant type.

Propagation: commonly used cuttings and sowing propagation. The main results are as follows: 1. Cutting propagation is suitable when the buds on the stem begin to sprout from April to May in spring. Select sturdy and substantial stems and cut them into cuttings 10 cm long. The milk from the incision should be washed and dried to prevent decay. The temperature of the sand bed for cutting was kept at 20-25 ℃, and it could take root in about 20 days. 2. Sowing and propagation can be carried out immediately after seed harvest, otherwise the seed germination rate will be reduced. The mature seeds were sown in the breeding sand bed and kept at 25 ~ 30 ℃ and a certain humidity. Generally, they could germinate in 10 ~ 15 days and transplant in 1 ~ 2 months.

Diseases and insect pests: Brown spot and anthrax are common, which can be controlled with 65% Dysen zinc 500 times solution. If the plant is damaged by scale insects or whitefly, it can be controlled by 1000 times of omethoate. Courtyard Flower Culture Guide living in cities in the 21st century, many people have lived in spacious, bright buildings, but many people still live in courtyards. Everyone is equal to the right to plant flowers and plants.

The woody flowers are: loquat, star anise gold plate, broad leaf ten meritorious works, loose tail sunflower, wine bottle coconut, sweet-scented osmanthus, among which the seeds of the first five kinds of flowers can be picked and sown after washing, but the fruits of sweet-scented osmanthus are black, soft and white when they are ripe, and after washing off the peel and flesh, they should be stored in clean wet sand until February of the following year, and then sow when the seeds are exposed. When picking seeds with sowing, we should pay attention to the following points when sowing: first, to keep the seedbed moist, but not stagnant water; second, to cover the grass to prevent the seeds from "budding"; and third, to remove the covered grass 2 to 3 times after seed emergence, and set up a shed to shade the seedlings in time to prevent the sun from burning the seedlings. In addition, although loquat is a large seed, but its bud top soil ability is weak, easy to bend, sowing too deep will affect the emergence rate and seedling rate, so it is appropriate to shallow sowing, generally ditch depth of 2 to 3 cm to cover soil to ditch full.
