Cultivation and Management techniques of Iris

Iris, also known as blue butterfly, flat bamboo flower and so on, is widely distributed in our country. The fragrance of Iris is light, but it smells very comfortable. Perfume made from Iris is very popular in our country. And the rhizome of Iris can also be used as medicine, which has the effects of detoxifying and eliminating accumulation, dispelling wind and blood stasis and so on. So how do we manage it when we plant irises? The following editor brings you the cultivation and management technology of Iris, let's have a look!

1. Post-planting management

Irises should be watered enough after planting, and then should be watered reasonably according to the growth of irises in the future to avoid water shortage and drought in the soil. If it is planted in September, then the sunshade net will be used for about half a month. In October, the shading material should be removed step by step, not at one time, to avoid blind flowers caused by drastic changes in light. We should pay attention to the proper covering cloth every night to improve the heat preservation capacity of the soil. Do a good job of ventilation during the day to prevent the temperature from exceeding 25 degrees.

2. Temperature control

Temperature is very important for the growth of Iris. After planting, the soil temperature should be controlled at about 5-20 degrees. Soil temperature has a direct effect on the emergence rate of iris, if the temperature is too low, then it will also reduce the flowering rate of iris, so after planting, the soil temperature should be controlled at about 17 degrees. We should adjust the temperature reasonably according to the planting mode, for example, when cultivated in the greenhouse, the temperature is controlled at about 15 degrees, and in the low light season such as autumn, in order to avoid the iris flowers withering, the temperature in the greenhouse should be reduced to about 12 degrees. Then in the open field cultivation, the temperature should be controlled at about 17 degrees, encountered high temperature season, should be properly shaded.

3. Pay attention to weeding

Weeds have a great effect on the growth of Iris. If weeds appear after Iris is planted, weeds should be weeded in time. However, when using herbicides, we should be careful not to cause harm to Iris. Make sure the bulb is buried deep enough that the herbicide cannot be infiltrated before it can be used, so make sure that the bud sprouting is at least two centimeters deep. Before the plant grows leaves, small weeds can be properly sprayed with herbicides, and the types of herbicides should be changed appropriately to avoid the resistance of weeds. Then pay attention to cleaning the plants in the morning of the next year to avoid pesticide residues.

4. Overwintering management

Iris actually has a strong ability to resist cold, but when we plant it to survive the winter. Because of different varieties and regions, it is still necessary to do a good job in overwintering management. When overwintering, we should pay attention to measures to increase temperature and keep warm, so as to protect Iris successfully through the winter. If we plant in the north, then we have to cover the soil with some materials such as straw to increase the soil temperature. When the environment is suitable in the spring of the following year, the bulb begins to be renewed. At this time, it is necessary to properly topdressing, increase nutrient accumulation and promote the growth of new bulbs, but the dosage should be controlled to avoid fertilizer damage.

The above is a brief introduction to the cultivation and management techniques of Iris. The management of Iris is very important. when we plant it, we should adjust the management method reasonably according to the growth stage of Iris to promote the growth of Iris. That's all for today's introduction. This article is for reference only. I hope it can help you all.
