How does the purple leaf sorrel cultivate purple leaf sorrel and precautions

Purple leaf grass must be no stranger to many people, it is a more common plant in life, because of its high ornamental value, it is deeply loved by consumers. The main ornamental point of Elaeagnus angustifolia is its leaves, which are purple and have white flowers. There are a lot of people raising it now, but there are also some things that need to be paid attention to when raising it.

How to raise Oxalis purpurea

1. Temperature. Oxalis prefers warm and humid environment, and the most suitable growth temperature is 16-22 ℃. The plants below 10 ℃ stopped growing and the leaves of 0 ℃ withered. However, as long as the underground roots are not frozen, new leaves can still germinate and grow normally in April next year. In winter, the leaves should be kept in normal state and the temperature should be kept above 5 ℃. Not resistant to high temperature, when the temperature is more than 35 ℃, the leaves curl, grow slowly, and enter the dormancy period. It is necessary to spray water to the leaf surface in time, shade and strengthen ventilation.

2. Light. Sorrel needs enough light to grow in full or half-day light. Spring and autumn season to receive sufficient sunlight, overcast will cause the leaves dull, at the same time petiole thin, plant type scattered. But also to avoid direct strong light, May to September to properly shade, so as to avoid sunburn. The phototaxis of sorrel is strong, and it should be placed on the balcony and windowsill during maintenance, and the position of the plant should be changed frequently so that it can receive light evenly around it.

3. Environmental humidity. Sorrel likes the humid environment, when the growth environment is dry, spray water around in time to improve humidity. When applying fertilizer to the pot, it is necessary to apply sufficient base fertilizer. In the growing season, nitrogen, phosphorus and potassium compound fertilizer was applied once a month in order to make the plant grow healthily and ensure that the leaves were thick and shiny.

Culture methods and matters needing attention of Elaeagnus angustifolia

1. Culture methods:

1. Watering. Resistant to drought, but like wet environment. During the growth period, keep the basin soil moist and adhere to the principle of "no dry, no watering, watering thoroughly". In the summer high temperature season, the plant enters the dormant period, at this time should spray water, keep the basin soil slightly wet. When the winter temperature drops below 10 ℃, watering should pay attention to dry rather than wet to prevent corm from rotting. Proper exposure to the rain is conducive to growth and development. However, it should be drained in time, the accumulated rain in the basin soil will cause the leaves to rot and cause the plants to die.

2. Fertilization. Pay attention to the concentration, too much concentration will burn the bulb and affect the growth. Fertilizer application was stopped from July to August. Be careful not to apply a single fertilizer, especially nitrogen fertilizer, which will change the leaves from purple to green and affect the ornamental. Do not splash liquid fertilizer on the leaf surface when fertilizing, it is easy to cause leaf disease.

2. points for attention:

The growth of sorrel is very fast and the pot should be turned every spring. When turning the basin, it is best to change the soil, the first choice is loose, fertile, well-drained medium-acid soil.

Propagation techniques of Elaeagnus angustifolia

1. Sow seeds. When choosing to sow, it is also necessary to determine the time, preferably in the spring. The seeds of purple leaf sorrel are relatively small, so it is difficult to sow seeds by hand, so we can choose the sifted culture soil to sow indoors. To pay attention to humidity and temperature maintenance, can be covered with a layer of plastic film to maintain humidity, the temperature should be kept above 15 ℃ to germinate. It can germinate about 15 days after sowing.

2. Ramet. First of all, take the plant out of the soil, be careful not to damage the roots, remove most of the persistent soil, and now separate the bulb slightly before planting in the new soil environment. It is best to break it gently with your hands. If you are going to plant bulbs in a pot, it is best to use 3-4 bulbs, not too many bulbs per pot. The excess leaves can be removed to reduce the absorption of water from the roots. In addition, the bud hole on its bulb can be cut off, placed in a sand bed and placed in an environment of 13 to 18 degrees Celsius, and new plants can grow quickly.

Common insect pests and control of Euphorbia angustifolia

Tobacco thrips: you can choose 1000 times the liquid fenitrothion, omethoate can also be used, but not excessive. Usually, it should be watered in time to remove weeds.

Peach aphid: we can choose imidacloprid and 150g water to make spray, the effect is remarkable. Similarly, in the usual breeding process, we should pay attention to clean up the withered leaves and flowers, and cut off the leaves with worms in time.

In fact, the culture method of purple leaf sorrel is very simple. We must pay attention to the control of temperature when breeding. When it is hot in summer, we must do a good job of sun protection and shade, and then the amount of fat and water also needs to be controlled. Only by doing these things well can we make the purple leaf grass grow better.
