How is iris generally used? What is an iris

In this study, the anti-tumor activity of five solvent extracts of irises aboveground parts, underground rhizomes of iris plants and underground rhizomes of iris plants on aminogalactosamine ( induced acute liver injury in mice, protective effect on acute liver injury induced by mice, and in vitro anti-tumor activity of and in use on liver fibrosis in rats induced by composite factors. The experimental results showed that they had protective effects on aminogalactosamine-induced acute liver injury in mice, acute liver injury in mice, liver fibrosis in rats caused by composite factors, and inhibitory effects on liver cancer and other cells. Therefore, they can be used in the preparation of drugs for the prevention and treatment of liver injury, hepatitis, liver fibrosis or liver cancer.

Remember.

Iris (yuan wei) is a kind of flower native to central China, and is now mainly distributed in central and southern China. The flowers are large and beautiful and can be viewed. Its rhizome can be used as traditional Chinese medicine, which can be harvested throughout the year and has anti-inflammatory effects.

Iris reproduction method Iris is a plant of the iris family Iris, which is a type of flower with high ornamental value. There are about 300 varieties worldwide, mainly found in the northern temperate zone. There are about 60 species, 13 varieties and 5 variants in China.

Iris plants are divided into two categories: root iris and bulbous iris according to the different underground stems: the iris with roots or rhizomes in the underground part is the iris with the roots, and the bulbous iris with the underground part is called bulbous iris. Irises are more hardy and can be cultivated in the open field.

The root iris germinates earlier in spring, the flowering period is usually from early spring to early summer, and enters a dormant state in winter, most varieties of aboveground stems and leaves die, but there are also some varieties where the aboveground parts remain green, so it is also called evergreen iris. Bulbous iris is mostly cultivated with the help of greenhouses for fresh cut flowers. Bulbs are generally planted in autumn, bloom in spring, and go dormant in early summer.

The reproduction methods of perennial iris and bulbous iris are described separately. Iris is mostly propagated by ramets, but sometimes it can also be propagated by seeds. Propagation is usually carried out every 2 to 4 years, in spring and autumn or after flowering.

Iris is divided after flowering (avoid the rainy season) and the flower buds are sufficiently differentiated before winter arrives, and they can bloom the following year. When splitting rhizomes, it is better to have 3 to 4 buds. If the ramets are too thin, it will affect flowering the next year.

When propagating by dividing, the upper leaves of the plant should be cut off and about 20 cm should be left for planting. Most species of iris should be planted shallowly. The planting spacing varies depending on the species, ranging from 50 to 50 cm for strong varieties and 20 to 20 cm for general varieties.

If propagation is carried out by seeds, it should be carried out as soon as the seeds are ripe, so that the seeds can germinate easily and can bloom in 2 to 3 years. Bulbous iris reproduces by bulbs. After a year of planting and flowering, a seed bulb will be depleted of nutrients and produce new balls, which will be surrounded by many daughter balls, and the daughter balls can develop into flowering balls after 1 to 2 years of planting.

In recent years, tissue culture has been carried out on different organs such as axillary buds, scales, stem disks, flower stems and other organs of bulbous iris to make them grow new bulbs, which provides a new method for accelerating reproduction and cultivating disease-free robust cue balls.

1. Soil selection. There are many ways to grow irises, not only in greenhouses, but also in the open field. The growth ability of iris is actually relatively strong, and under normal circumstances, it can be planted on most soils.

It is not enough to ensure a good soil structure, such as good drainage and irrigation, strong water and fertilizer retention ability, and not easy to compact, etc., which is the basic condition for long-term large-scale planting of iris. Before planting, we can add an appropriate amount of peat, coarse sand and other substances to the soil to improve the soil and promote the growth of irises.

2. Reproduction methods. The flowering period of iris is in the spring of each year, and the flowering time is about 3 times. Generally, it is done in May by dividing or sowing, but it can also be done in autumn and about 3 years after planting.

When we cut rhizomes, we should ensure that there are at least two adventitious buds in each tall rhizome to improve the rooting and germination rate. In the case of seeding propagation, it is necessary to sow the iris seeds as soon as they are mature. It takes at least two years for the seedlings to bloom, and when planting, the plant row spacing is controlled at about 50 cm, and the planting depth is 7 cm to ensure the growth of the seedlings.

3. Water and fertilizer management. When planting irises, it is necessary to pay attention to controlling the amount of watering and keeping the soil moist. The planting plot should have a good drainage and irrigation system that is easy to drain during the rainy season or when stagnant water is generated.

Unlike other crops, iris should not be fertilized before planting, because it is easy to increase the salinity of the soil and reduce the growth rate of iris roots. Before topdressing, we need to test the soil formula to find out the lack of nutrients in the soil, so that the nutrients can be supplemented during topdressing. It should be noted that we should avoid using fertilizers containing fluoride when fertilizing, otherwise it is very easy to cause iris death.

4. Disease prevention and control. Disease control is an indispensable management measure when planting iris, and common diseases of iris include bulb rot and crown rot. We should strengthen management during planting, control the temperature and humidity in the field, and disinfect seeds and bulbs before planting.

Reduce the base number of pathogens in the garden to ensure the normal growth of iris. In the event of an abnormal iris occurrence, it is necessary to find out the cause in time, and then use the corresponding agents and treatment methods to prevent and control it, reduce the damage area and reduce the loss.

When the iris is just bought, the first thing to pay attention to is the soil, environment and water and fertilizer, so let's take a look.

Soil selection. Irises prefer rich and fertile soils rich in humus, prefer clay soils to acidic soils, and are more suitable for growing in neutral or alkaline soils. Newly bought irises generally do not need to be replaced.

However, if the soil quality is not good, it can also be replaced.

Temperature requirements. The newly purchased iris has come to a new environment, and it needs to be given a relatively comfortable environment to help it begin to grow. It is best to keep the temperature at 15-17 and also provide warm sunlight.

In daily life, the temperature of the growing environment should be adjusted in a timely manner, such as in summer, the sunshade should be properly cooled down to avoid sunburn.

But don't be dehydrated, if you don't have enough water or experience a lot of water shortage, it will cause iris to sprout slowly and develop poorly. In addition, wait until the iris has adapted to the environment before considering whether to apply fertilizer or not, and you can add some base fertilizer when changing pots.
