1, the planting of plum blossoms

In the south can be planted in the ground, in the Yellow River Basin hardy varieties can also be planted in the ground, but in the northern cold areas should be potted indoor wintering. After the leaves fall to spring before the buds can be planted. In order to improve the survival rate, should avoid damage to the root system, with soil mass transplantation. Ground planting should be selected in a windy and sunny place. Potted plants use 3 parts of rotting leaves, 3 parts of garden soil, 2 parts of river sand, 2 parts of rotting stable fertilizer evenly mixed with the culture soil.

Pour water once after planting. Put in the shade to maintain, and when growth resumes, move to the sun under normal management.

2, Plum on the light and temperature requirements

Like warmth and plenty of light. In addition to the apricot-plum varieties can tolerate -25 ℃ low temperature, generally tolerate -10 ℃ low temperature. Tolerant of high temperatures, can grow at 40 ℃ conditions. In the average annual temperature of 16 ~ 23 ℃ area growth and development of the best. Very sensitive to temperature, flowering in early spring when the average temperature reaches -5 ~ 7 ℃.

3, plum watering and fertilization

Growing period should pay attention to watering, and often keep the potting soil moist in the state, neither water, nor too wet and too dry, watering to grasp the principle of see dry and wet. Generally cloudy, low temperature less watering, otherwise more watering. Summer can be watered twice a day, spring and fall watering once a day, winter is dry and watered.

Fertilizer is also reasonable, before planting a good base fertilizer, mixed with a small amount of potassium dihydrogen phosphate, before the flower and then apply 1 time potassium dihydrogen phosphate, flower Shi 1 time rotted cake fertilizer, supplemental nutrients. June can also be applied once the composite fertilizer to promote the differentiation of flower buds. After the fall of leaves in autumn, apply 1 time of organic fertilizer, such as rotted manure.

4, plum blossom shaping and pruning

Plastic pruning ground planting plum blossom shaping and pruning time can be carried out within 20 days after flowering. Natural tree shape, cut off cross branches, upright branches, dry branches, too dense branches, etc., short cuts on the side branches to promote flowering and foliage.

Pot Plum plant planting method

Pot Plum plant is mainly grafting culture, commonly used cutting and budding. Rootstock with hairy peach hickory or apricot. Apricot tree old trunk skin red, grafting red plum, flower skin color coordination.

1, cut

Cutting more than one or two years old rootstock, at the end of March (in the cold room) or early April (in the open ground), 3-5 cm from the ground will be cut off the upper part of the rootstock. The scion is made from a robust annual branch, cut to a length of 5-6 cm, leaving at least 3 buds. In the next bud on the outside of the two sides downward diagonally cut into a duckbill shape. Make a 3-centimeter-long interface on one side of the rootstock.

Insert the scion into the cutting of the rootstock so that the two form a close union, and then tie it with plastic film tape. Or use polyester tape to stick tight. Finally, use a small plastic bag to set up the scion, the bag is tied below the interface, you can often check through the film. To be viable, the bundle will be removed.

2, budding

Budding in August and September, generally more "d" shape method. First in the scion buds above 1 a 1 .5 centimeters at the horizontal cut a knife, and then from the buds below 1 centimeter below the front down below the flat cut, the cut buds of the cortex of the internal wood gently peeled off (in recent years there is a slightly woody buds) containing the population.

The rootstock from the soil surface 5 cm across a cut, and then from the center of the incision down a cut, "Ding" shape, and then gently peeled the cortex, the ready scion inserted into the cortex of the "Ding" mouth. Splicing buds to stick solid, the upper end of the rootstock and rootstock "d" mouth of the upper end of the close combination, and finally tied with plastic film strips or polyester tape shelves.

A week later to check the survival of the situation, if the petiole a touch to fall, buds green full that is said to be alive. The following spring from the interface up 5-6 cm at the top of the rootstock will be cut off, the scion will soon sprout, and then pay attention to cut the rootstock buds, to be replaced in pots or potted planting, can be appropriate down deep planting, so that the interface as far as possible to fall, according to the length of the tie, leading to the composition of its beautiful modeling.

3, the preparation of potting soil

To 1/3 of the chaff ash and 2/3 of the river mud and add human feces and urine, mix well, put in the sun after exposure, sieve for use. The bottom of the basin pad tile, stone, to facilitate drainage, and then loaded with coarser-grained soil, and then planted plum stakes, buried and compacted roots.

4, watering time

Watering is not recommended when potting; watering once after 3~4 days; watering once a day after 7~10 days; after survival, watering 1~2 times a day during May~August. The soil should not be too wet, do not rout water.

5, fertilization

Plums do not like big fertilizer, when the new growth to about 5 cm can be applied once a thin broken bone mace fertilizer to promote the growth of strong branches. Release the leaves when the fertilizer should be sufficient, generally 1 time a month to apply dilute liquid fertilizer, in order to promote the branches and leaves luxuriant. To be branches grow to 20-25 cm should be restrained fertilization. In late summer and early autumn, 2 times of fertilizer, in order to promote the differentiation of flower buds. After each fertilization should pay attention to timely watering and loosening the soil, in order to keep the potting soil loose, conducive to the development of the root system.

6, temperature, light

Plums like sunny and well-ventilated environment, intolerant of long-term shade. Only to give sufficient light, so that it obtains the conditions for photosynthesis, in order to obtain sufficient nutrients, and therefore can grow strong, open both large and large bright flowers
