Alice is a deciduous shrub that spends its first leaves and golden yellow flowers. Capsule oval, seeds with wings. Hi-light shade, ability to -50 °C cold, drought-resistant thin but fear of embarrassment. Now its seedling technology is introduced as follows.

First, planting seedlings

1. Seed-picking and bud-processing The pods are harvested and spread to the sun for storage. Seed weight 4.5 g, seeding rate 100 g/10 m2, seedling volume 3000/10 m2. Seed treatment at the beginning of April, disinfection with 0.5% potassium permanganate solution for 3 hours, soaking in 30°C warm water for 48 hours, fishing After mixing out 3 times sand, place it in a room at 10°C to 20°C. Frequently turning to keep the moisture content of the species sand 60%, and after 40 days, the seeds are 1/3.

2. Make bed and sowing. Choose dry, well-drained land and make a bed that is 10 meters long, 15 centimeters high, and 1 meter wide. 30 grams of bed soil mixed with 5 grams of quintozene nitrobenzene, and 5 grams of dexsen, made of medicinal soil. Before sowing, a layer of medicine soil is applied, and the soil is sowed after sowing or sowing. The thickness is 3 times the diameter of the seed. Pressurize the irrigating water, then pour the grass ether that weeds the weeds once, and do not water it within 10 hours.

3. Seedling management and keep the bed moist after wintering sowing, timely loose soil top dressing, when the seedling height up to 60 to 90 cm. After the defoliation, the seedlings were graded and pre-sealed before being frozen, and when the top soil was used for afforestation, the seedlings were changed for ridge cultivation.

Second, cutting seedlings

1. Picking and scissoring Choose one or two years of robust, disease-free pests, with 10 to 15 cm in length, 0.3 to 1.5 cm in diameter, and 1 to 2 strong buds at the top. The cut is smooth and the lower end is cut into a 45 degree bevel. Before the sap flowed in the late autumn and early winter or early spring, it was cut along with cutting, then buried in sand and cut in July.

2. Do beds and cuttings to make beds with seedlings. The bottom of the bed is filled with brewing material that is 20 centimeters thick. The bed is then filled with soil and the substrate is 20 centimeters thick. Before cutting, the cuttings were soaked in fresh water for two days and then soaked with ABT rooting powder at 50 ppm for 2 to 4 hours. 1015 centimeters in depth, 6 to 10 centimeters in depth, then watered.

3. Shed and management After inserting, take a 60cm small arch and cover with plastic film. 1 to 2 days of pouring water, keep the bed moist and water, humidity 70% to 90%, ground temperature 23 °C to 24 °C, temperature 25 °C to 28 °C, about 20 days after the rooting of leaves. During the period, weeding and soil fertigation.

Third, layering seedlings

Choose strong and strong branches in early spring, dig a pit with a depth of 20 centimeters, press the stick and break the skin into the pit, and pour the water into the soil. After the shoots are rooted and new seedlings are cut off, new strains are formed.

Fourth, rooting seedlings

In the early spring, under the crown from the mother 70 centimeters outside the loose soil fertilization watering, so that the roots of the surface sprouting buds, the emergence of new strains. After artificially nurturing, seedlings that meet greening standards are cultivated. Battening, rooting and seeding methods are generally used less frequently.
