Cassava mosaic cultivation methods and precautions

Morphological characteristics of flower and leaf cassava

Erect shrub, about 1.5 m tall, 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, with several flowers.

Like warm and sunny environment, not cold-resistant, afraid of frost, resistant to semi-shade, cultivation environment should not be too dry or too wet.

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.

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

Flowered cassava prefers a warm, dry and sunny environment. More cold-resistant, drought-resistant, not resistant to moisture. The requirement of soil is not strict, and the fertile sandy loam grows better.

The winter temperature is not lower than 5 ℃. After the ear takes root, it should be planted in a pot in time, otherwise the rooted cuttings are easy to rot. Pot soil can be compost, loam half, plus 5% eggshell powder and even the best. When changing pots or newly planted plants in spring, it is not appropriate to immediately water, just spray water to make the potted soil slightly moist.

Cassava water for flowers and leaves should not be irrigated too much, dry rather than wet, sufficient sunshine should be needed during the growth period, fertilizing once a month, fertilizer should be applied thinly and frequently, but it should be careful not to pour liquid fertilizer on the palm. If it has been poured on the palm, it should be washed with clean water immediately to avoid decay and affect the viewing.

Growing cassava with flowers and leaves indoors can absorb carbon monoxide, carbon dioxide and nitrogen oxides from the air and purify the air. It can also increase the concentration of negative ions in the air, keep the air fresh and beneficial to health.

Control of diseases and pests of cassava with flowers and leaves

Common brown spot and anthrax hazards were sprayed with 65% Dysen zinc wettable powder 500 times. Insect pests are harmful to whiteflies and scale insects, which are sprayed with 1000 times of omethoate EC.

Common species of flower and leaf cassava

Cassava (M.peltata): leaf blade peltate, entire, grayish green. Leaf veins protruding, pink. Mosaic cassava, also known as variegated cassava, is native to tropical America. Like warm and sunny, not cold-resistant, the cultivation environment should not be too dry or too wet, the soil requires fertile, loose and well-drained slightly acidic loam, the winter temperature is not lower than 15 ℃.
