The Latest Iris Cultivation and Management Techniques Tutorial
Iris is also called blue butterfly, flat bamboo flower and other names, and its distribution range in our country is relatively wide. The fragrance of iris is relatively light, but it smells very comfortable. Perfume made from iris as a raw material is very popular in our country. Moreover, the rhizome of iris can also be used as medicinal material, with effects such as detoxifying and reducing stagnation, dispelling wind and removing blood stasis. So how should we manage iris when planting it? Below, the editor brings you the cultivation and management techniques for iris. Let's take a look together!
1. Management after planting
After planting iris, pay attention to watering thoroughly, and afterward water reasonably according to the growth condition of the iris, avoiding soil water shortage and drought. If planting is done in September, then use a shade net for shading for about half a month. In October, the shading material should be removed step by step, not all at once, to avoid blind flower phenomenon caused by drastic changes in light. Every night, pay attention to properly covering with cloth to improve the soil's heat preservation capacity. During the day, do a good job of ventilation and air exchange 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 around 5-20 degrees. Soil temperature has a direct impact on the emergence rate of iris. If the temperature is too low, it will also reduce the flowering rate of iris, so after planting, the soil temperature should be controlled at around 17 degrees. We should reasonably adjust the temperature according to the planting method. For example, when cultivating in a greenhouse, control the temperature at around 15 degrees. In weak-light seasons such as autumn, in order to avoid iris flowers withering, lower the greenhouse temperature to around 12 degrees. Then when cultivating in the open field, the temperature should be controlled at around 17 degrees. In high-temperature seasons, shade appropriately.
3. Pay attention to weeding
Weeds have a very large impact on the growth of iris. If weeds appear after iris planting, then remove them in time. However, when using herbicides, pay attention not to cause harm to the iris. It is necessary to ensure that the bulbs are buried deep enough that herbicides cannot penetrate before use, so ensure that the young buds sprouting from the bulbs are at a depth of at least below two centimeters. Before the plants have grown leaves, small weeds can be appropriately sprayed with herbicides, and the types of herbicides should be appropriately changed to avoid weeds developing resistance. Then in the morning of the second year, pay attention to washing the plants to avoid pesticide residue.
4. Overwintering management
The cold resistance of iris is actually relatively strong, but when we prepare for overwintering after planting, due to differences in varieties and regions, we still need to do a good job of overwintering management. During overwintering, pay attention to doing a good job of heat preservation and warming measures to protect the iris through the winter successfully. If planting in the north, then we should cover the soil with some materials such as straw to increase soil temperature. In the second spring, when the environment is suitable, the bulbs begin to renew. At this time, appropriately apply topdressing to increase nutrient accumulation and promote the growth of new bulbs, but control the amount well to avoid fertilizer damage.
The above is a brief introduction to iris cultivation and management techniques. The management work for iris is very important. When planting, we should reasonably adjust management methods according to the growth stages of iris to promote the growth of iris. That is all for today's introduction.
