Oxalis purpurea is an exotic plant, but it has been successfully introduced in China. About the origin of oxalis purpurea, some people say it is Brazil, others say it is Mexico, so I won't go into details here. Oxalis purpurea is a good foliage plant. Because its maximum height is only 30 cm, it is very beautiful to cover the ground when planting in pieces. The following agricultural encyclopedia will take a look at the conservation methods of this plant and understand the growth needs of oxalis purpurea.

Oxalis purpurea likes warm and humid environment and is relatively drought-tolerant. The optimum growth temperature is 16℃ ~ 22℃, and sufficient illumination is needed. In addition to the need for proper shade in summer, it can be maintained by adequate sunshine in peacetime. Let's take a concrete look at the maintenance methods of oxalis purpurea.

I. Temperature

Oxalis purpurea is not cold-tolerant. When the temperature is below 10℃, the plants stop growing and the leaves wither at 0℃. But as long as the underground roots are not frozen, new leaves can still germinate and grow normally in April next year. In winter, in order to ensure the normal state of blades, the temperature should be kept above 5℃. At the same time, it is not resistant to high temperature. When the temperature exceeds 35℃, the leaves curl and grow slowly, and enter the dormant period. It is necessary to spray water on the leaves in time, shade them and strengthen ventilation.

Second, light.

In spring and autumn, it is necessary to receive enough sunshine. Excessive shading will cause dim leaves, thin petioles and scattered plant types. However, direct glare should also be avoided, and shade should be done properly from May to September to avoid sunburn. Oxalis has strong phototaxis, so it should be placed on the balcony and windowsill when it is maintained, and the position of the plant should be changed frequently to make it receive light evenly around.

Third, moisture.

During the growing period, keep the soil moist and persist. If you don't do it, you will fall completely. The principle of. In the hot summer season, plants enter dormancy, and at this time, water should be sprayed to keep the basin soil slightly wet. When the temperature drops below 10℃ in winter, the water should be dry but not wet to prevent bulbs from rotting. Proper contact with rain is conducive to growth and development. However, it is necessary to drain water in time, and the accumulated water in the basin will rot the leaves and cause the plants to die in pieces. When the growing environment is dry, spray water around it in time to improve the humidity.

Fourth, fertilization.

Apply enough fat when serving the basin. In the growing season, in order to make plants grow healthily and ensure thick and shiny leaves, NPK compound fertilizer is applied once a month. Pay attention to the concentration when fertilizing. Too high concentration will burn bulbs and affect growth. Stop fertilizing in July and August.

Be careful not to apply chemical fertilizer alone, especially nitrogen fertilizer, which will turn the leaves from purple to green and affect the viewing. Don't splash liquid fertilizer on leaves when applying fertilizer, which may easily cause leaf diseases.

Verb (short for verb) pruning

Oxalis purpurea needs pruning when:

1. When plants grow too vigorously, dense leaves should be removed in time to improve ventilation and light transmission conditions and promote growth.

2. Of course, in daily maintenance, dead leaves should be removed in time to reduce the occurrence of pests and diseases.

3. flowers are beautiful. When the petiole is too long or the plant shape is not beautiful, you can cut the leaves again and let them grow new leaves again.

The above is the maintenance method of oxalis purpurea introduced by agricultural encyclopedia. It can be seen that the maintenance of oxalis purpurea is relatively simple. This kind of plant is more suitable for group cultivation. Purple plants can cover the ground, which is very spectacular. At the same time, oxalis purpurea has a certain effect, and it has the effect of detumescence and pain relief for external use.
