Dream of Flowers
According to Xishu Miscellanies, during the Sino-Japanese War of Chenghua in the Ming Dynasty, Japanese messengers came to China, and when they saw the sunflower in front of the column, they understood it, so they wrote a poem: "Flowers are similar to hibiscus flowers, with leaves more than hibiscus leaves. The five-foot railing can't be covered, and half of it is still left for people to see. " The hollyhock sticks out of the five-foot railing, and half of it is outside, which is one foot high. The nickname of hollyhock is red, and I think it comes from this. In ancient times, people thought that bean sprouts, yellow croaker, Monopterus albus, cucumber and realgar wine were used for dieting in Duanyang to get rid of diseases and strengthen the body, and things such as hollyhock, pomegranate and cattail were inserted in bottles at home to ward off ghosts and evil spirits. It is said that the leaves of hollyhock are ground into juice, wiped on bamboo paper with cloth, slightly dried and flattened with stone, and it becomes a sunflower note. In the Tang Dynasty, Xu Yuan made this note and gave it to Bai Juyi and Yuan Zhen, who wrote poems and sang with each other. It is said that this kind of paper is green and smooth, but unfortunately no one has the pleasure to make this kind of paper nowadays.
planting:
1. propagation method of hollyhock:
hollyhock is usually propagated by sowing, but also by branching and cutting. Branching and cutting are mostly used for the propagation of fine varieties.
spring sowing and autumn sowing can be used. Depending on the number of seeds of hollyhock, it can be sown on the seedbed in the open field, and then transplanted, or it can be directly planted in the open field without transplanting. Autumn sowing is often used in the south, and it is usually appropriate to sow in the open seedbed in September to germinate neatly. In the north, spring sowing is the main method. The seeds of hollyhock can be sown when they are mature, and normally the seeds can germinate in about 7 days. The germination ability of the seeds of Abelmoschus manihot can be maintained for 4 years, but the growth of seedlings will decline after 2 ~ 3 years of sowing. Direct sowing in the open field, if properly combined with transplanting in rainy days, can not only interplant seedlings, but also benefit from planting flowers for many years at a time.
the division of hollyhock is carried out in autumn, and the clustered roots of perennial hollyhock are dug out in time, cut into several small clusters with a sharp knife, so that each small cluster has two or three buds, and then planted separately. Strengthening water management slightly in spring.
after cutting flowers, it can be done in winter. The lateral branches germinated at the base of the old stem of hollyhock were used as cuttings, which were about 8cm long and could be inserted into dry sand beds or pots. After inserting, cover it with plastic film for moisturizing, and place it in the shade until it takes root. Before and after winter, electric heating lines should be laid under the bed to increase the ground temperature, which can accelerate the generation of new roots
2. Cultivation and management of hollyhock: < P > hollyhock likes cool climate, avoids heat and frost, likes light and is slightly tolerant to shade; Suitable for deep, fertile and well-drained soil.
The cultivation and management of hollyhock is relatively simple. When the seedlings grow 2 or 3 true leaves, they should be transplanted once to increase the row spacing. After transplanting, it should be watered in time, and topdressing should be applied once or twice in combination with intertillage and weeding before flowering, with phosphorus and potassium fertilizer as the best topdressing. Seeding seedlings can be planted in November after transplanting once. During the seedling growth period, liquid fertilizer is applied 2-3 times, mainly nitrogen fertilizer. At the same time, the soil is often loosened and weeded, which is beneficial to the growth of plants. When flower buds are formed in the axils of hollyhock leaves, topdressing phosphorus and potassium fertilizer once. In order to prolong the flowering period, enough water should be kept. Cut off the aboveground parts in time after flowering, and sprout new buds. When potted, it should be potted in early spring, and only one flower should be kept. Because the seeds of hollyhock are easy to scatter when they are ripe, they should be harvested in time. After 3-4 years of planting, plants are prone to aging, so they should be updated in time. In addition, hollyhock is easy to cross, and in order to maintain the purity of varieties, different varieties should keep a certain distance. Abelmoschus manihot is vulnerable to leaf rollers, aphids and red spiders, and old plants and dry weather are prone to rust, so it should be prevented in time.
