The best season is spring or summer, the temperature is suitable, the humidity is just right, planting red leaf plum can get excellent results, the survival rate is quite good. Red-leaf plum is a kind of adaptable plant, whether in the sun, dry place, can get to grow.

Selection of nursery land and preparation of cuttings:

1. Selection of nursery land

On a sandy loam or loamy soil plot with a backdrop of the wind and the sun, a flat topography, well-drained, and more fertile.

2. Preparation of cuttings beds

Cuttings beds can be flat beds or low beds, flat beds are level with the ground; low beds bottom at the ground 10 cm to 15 cm. Bed width of 1 meter to 1.5 meters, east-west direction for the bed, bed length depending on the amount of cuttings. The northern part of the low bed, made into a ridge south low north high sun beds, mainly conducive to improve the ground temperature and moisturizing.

3. Organize the seedbed

1 kg to 2 kg of rotted organic fertilizer per square meter, deep turning 25 cm, leveling and harrowing. Then sprayed with bacterial disinfectant wettable powder 300 times liquid disinfection, disinfection after the cover film closed bed.

4. Arch

Use 2 cm to 3 cm wide bamboo pieces as a support. The length of the bamboo sheet depends on the height of the arch and the width of the border, usually 50 cm to 80 cm high, the number of bamboo sheets is calculated according to the length of the border, one arch per meter. The trellis is usually 0.08 mm thick white trellis, and at the same time prepare the straw thatch for cold protection.

Cuttings:

1. Selection of Seed Strips

It is necessary to select high-quality one-year robust sprouts and branches that are free of pests and diseases, free of mechanical damage, and with diameters of 3 mm to 10 mm.

2. Spike handling

It is best to choose the middle and lower part of the lignified germplasm. Spike is generally cut into 10 cm to 12 cm long, the upper 1 cm from the bud cut flat, the lower cut into the oblique, 50 to 100 a bundle. After being treated with a solution of WoPing Power Rooting Powder for 10 to 12 hours, or a solution of 50 ppm naphthalene acetic acid for 2 hours, the cuttings can be taken out and dried.

3. Density and method of cuttings

The spacing between plants is generally 5cm x 8cm, with about 200 to 300 cuttings per square meter. The cuttings are not removed from the ground film, the cuttings are inserted through the ground film, the depth of 3/4 of the spike length. 1 to 2 buds should be exposed on the ground after the cuttings are inserted, and after the cuttings are inserted, a layer of crushed soil of about 1 centimeter is sprinkled, in order to facilitate watering so that the cuttings are closely connected to the soil.

Management of cuttings:

1. Immediately after inserting the spike, water thoroughly once.

2.Watering in a timely manner after the cover film, surrounded by soil compaction, the temperature can be high at both ends of the ventilation.

3.When the winter night temperature drops to -5 ℃, every day after 4 p.m. need to cover grass thatch to prevent freezing, 10 a.m. in the morning months of dry grass thatch to increase the temperature.

4.Early March according to the soil moisture in the seedbed, you can water thoroughly once. At the same time, we should pay attention to check whether there are diseases, insects, weeds and other occurrences, if any to timely control. When the daytime temperature in the shed reaches more than 30 ℃ should pay attention to air ventilation.

5. Uncovering time in April, in the middle of the film, before uncovering the film to carry out refining, that is, first uncovered a small part of the film, ventilation and light, and then gradually increase. Refinement of 7 days to 8 days can be all removed from the film

6.In addition to timely control of disease, pests, grasses, but also pay attention to fertilization, every 50 days to 60 days to apply nitrogen fertilizer, and watering, every 15 days or so, with 0.3% of the urea or potassium dihydrogen phosphate foliar fertilizer. Seedlings can grow to more than 1 meter that year.
