The method of maintaining yellow iris

Yellow irises like water, so the soil moisture must be maintained very well, but moist soil is easy to breed germs.

Therefore, when planting it, the soil had better be disinfected once a year, and the soil should be turned deeply to dry for a period of time. In addition, in terms of soil structure, the sandy soil environment has a good effect on the growth of Iris, because the sandy soil is permeable and permeable, which is very suitable for the root development of Iris.

The above is the introduction of some planting methods of yellow iris, which can be understood by the friends who want to grow it. In addition, the growth of yellow iris is inseparable from careful maintenance, if you want to raise a beautiful and healthy yellow iris, we must pay attention to daily maintenance methods.

The Culture method of Iris flavescens

Irises can be planted either in protected or open fields. Iris can be planted in any type of soil as long as it is well drained, moisturized and unhardened. Good soil structure is very important for the growth of Iris, and the cultivation effect of sandy loam is the best, because the aeration and permeability of sandy loam is good, which is very beneficial to the expansion of Iris root system.

Iris soil had better be disinfected once a year, soil disinfection is a very important link, generally using deep drying or chemical disinfection methods. The general time of deep turning and drying is about 20 days, and chemical disinfection is generally carried out by spraying chlorothalonil or pentachloronitrobenzene.

The seed balls must also be sterilized before planting and soak in 1/1000 carbendan or chlorothalonil water solution for 30 minutes. Disinfection and planting should be carried out immediately after the seed balls arrive. If they cannot be planted immediately, they must be stored in a well-ventilated cold storage below 2 ℃ for no more than two weeks. Storage for too long will be detrimental to the growth of stems and leaves and increase the chance of penicillium infection in the root cap.

In order to improve the structure of clayey soil, plant ash, perlite and coarse sand can be applied to the soil surface before planting and then mixed with deep ploughing; if the soil is sandy and leaks too fast, mulch such as rice husk, pine needle and peat can be sprinkled on the surface of the soil after planting to alleviate it.

The leaves of the yellow kite are as green as swords, the flowers are colorful and beautiful, and they are plants with high ornamental value. How to raise the yellow irises? What are the ecological habits? Let's take a look at it next.

First, the culture method of Iris flavescens

1. Soil: good soil structure is very important for the growth of Iris, and the cultivation effect of sandy loam is the best, because the aeration and permeability of sandy loam is good, which is very beneficial to the expansion of Iris root system. In order to improve the structure of clayey soil, plant ash, perlite and coarse sand can be applied to the soil surface and then ploughed and mixed before planting.

2. Disinfection: the soil planted with Iris had better be disinfected once a year. Soil disinfection is a very important link, generally using deep drying or chemical disinfection. The general time of deep turning and drying is about 20 days, and chemical disinfection is generally carried out by spraying chlorothalonil or pentachloronitrobenzene. The seed balls must also be sterilized before planting and soak in 1/1000 carbendan or chlorothalonil water solution for 30 minutes.

3. Planting: when planting iris, the soil temperature should be lower than 20 ℃. If the average temperature during the cultivation period is expected to exceed 23 ℃, irises cannot be planted and the planting period must be advanced or postponed.

4. Temperature: the soil temperature after planting is very important, the lowest temperature is 5-8 ℃, the highest temperature is 20 ℃, and the optimum temperature is 16-18 ℃. The lowest temperature is 5 ℃, the highest is 25 ℃, and the optimum temperature is 15 ℃.

5. Watering: Iris likes water. In the process of cultivation, the soil should be kept moist and too dry, which is not conducive to plant growth. Generally, in the non-rainy season, permeable water can be irrigated every 10 days or so, rain can be natural in the rainy season, and antifreeze water should be irrigated at the end of autumn. The thawing water should be poured in time in the early spring of the following year, and the thawing water must be poured thoroughly. Water must be watered once before planting to ensure that the soil is moist during planting and is conducive to rapid rooting. Water again after planting to make the soil in full contact with the same kind of ball.

6. Fertilization: it is not advisable to apply base fertilizer (except organic fertilizer) before planting, because Iris is very sensitive to soil salinity. If you apply fertilizer before planting, it will increase the salt content in the soil and hinder the hairy roots of Iris. The method of topdressing in the later stage can be used, but Iris is more sensitive to fluoride, such as calcium superphosphate and triphosphates are prohibited, and diphosphates with low fluorine content can be used.

7. Weeding: in the nursery where irises are planted, weeding should be done well in advance. If there are weeds in the process of planting, they should be pulled out manually in time, and chemical herbicides should not be used to remove weeds as far as possible.

Second, the growth habits of Iris flavescens

Iris grows on shrub margins, sunny slopes, forest margins and waterside wetlands in the wild. The planting environment likes to be moist and well drained, sandy loam or light clay rich in humus, has a certain saline-alkali tolerance, and can grow normally in a mild saline-alkali soil with a pH value of 8.7 and a salt content of 0.2%. Like light, but also more resistant to shade, in the semi-overcast environment can also grow normally. Like warm and cool climate, strong cold resistance.

The above are the breeding methods of yellow iris and the introduction of the growth habits of yellow iris. I hope it will be helpful for everyone to cultivate yellow iris. Also want to know more about Huanghua Iris, continue to follow us.
