The Culture method of Prunus mume

Seedling management: the five-petal plum will germinate 7-10 days after sowing, and the temperature should be controlled at about 20 ℃ after the seedlings are unearthed, so as to keep the room ventilated and transparent. Planting soil: garden soil, compost, prepared according to the proportion of 4:1, and add appropriate amount of calcium superphosphate. Pot: wait for the seedlings to grow to 2-3 pairs of true leaves. Pick the heart: pick the heart at the right time. Rational fertilization: timely fertilization should be applied one week after planting. Moisture: the leaf surface should be kept dry and the bottom of the basin should not be filled with water.

I. Seedling management

Under normal circumstances, Prunus mume will sprout about 7-10 days after sowing. After the seedlings are unearthed, the temperature in the nursery room should be controlled at about 20 ℃ to keep the room ventilated and transparent, so as to prevent the seedlings from overgrowing.

Second, planting soil

The five-petal flower has relatively high requirements for soil, and should be configured according to the principle of air permeability, water retention and rich matrix. Garden soil and compost can be selected and prepared according to the proportion of 4:1, or garden soil, compost, and rotten leaf soil. It is prepared according to the proportion of 3:1:4, and about 1000 grams of calcium superphosphate are mixed in each cubic meter of matrix.

Third, put on the basin

When the seedlings grow to 2-3 pairs of true leaves, you can put on the pot, first put broken tiles and cinder at the bottom of the flowerpot, then put an appropriate amount of nutritious soil, put the five-petal plum seedlings into the pot, put the plants straight so that the roots can be fully stretched, and finally backfill the soil and compact. pour enough fixed root water.

Fourth, pick the heart

Prunus mume seedlings can begin to pick out the heart when they grow to 3-4 pairs of true leaves, which is beneficial to promote the germination of lateral branches and make the plant type more plump and symmetrical, and some varieties do not need to pick the heart, such as Qingjing and so on.

V. rational fertilization

About a week after plant planting, the seedlings grow rapidly and need timely fertilization to meet the needs of plant growth. 1000-fold solution of "flowering essence" can be properly applied, which should not be excessive.

VI. Growth temperature

Prunus mume is a kind of flower which is relatively heat-resistant and cold-scared. The suitable growth temperature is about 20-30 ℃, and the temperature is as high as 35-37 ℃. For example, when the temperature is lower than 15 ℃, the growth is relatively slow. When the temperature is lower than 10 ℃, it will affect its growth, and in serious cases, it will cause frostbite and death.

7. Lighting

Five-petal plum needs all-day sunshine in the growth process, and can grow normally in a shady environment, but the number and size of flowering will be relatively small, and the florescence will be relatively short. Therefore, ensuring a certain amount of light in the plant is more conducive to promoting flowering.

8. Moisture

Five-petal plum is more suitable for growing in a relatively dry climate, such as high temperature and rainy season, it is easy to cause epidemic disease, resulting in a large number of plant death, so it is necessary to keep the leaves dry in the process of culture, and the bottom of the basin should not accumulate water.
