Good planting of honeysuckle in September

Cutting propagation: cutting was carried out before the germination of new buds in early spring or from September to October in autumn. The seedbed should be close to the source of water, turn the land deeply and apply sufficient fertilizer. Open a high bed 1.3 meters wide. The 1-to 2-year-old branches with strong growth and no diseases and insect pests were selected, cut into cuttings about 33cm length, and the lower leaves were removed, and then the horizontal trenches were opened according to the row spacing 27~30cm on the border. The length of the cuttings depended on the length of the cuttings. 10 cuttings were placed in each trench, and the cuttings were buried in human soil.

Ramet propagation: select strong plant type, uniform hair, large root circumference, dark green withered leaves, disease-free insect, 2-3-year-old persistent root, direct ramet as seedlings. The old plant of 2x3 was retained. The seedlings were separated from the soil with roots and roots, and the survival rate of transplanting could reach more than 90% before the plants of "the Beginning of Winter" and "sting" sprouted the following year.

Seed reproduction: pick the fruit in November, scrub it in water, clean the pulp and blighted seeds, and take the mature seeds to dry. In April of the following year, the seeds were soaked in warm water for 35-40 ℃ for 24 hours, then mixed with 3 times wet sand to accelerate germination. When the seed crack reached about 30%, the seeds could be sown. Before sowing, select sandy fertilizer soil, turn it 30 cm deep, and form a flat bed with 70cm width. There is no limit to the length of the bed.

Colonization: it can be planted in autumn and early spring. Use barren slopes, gaps or mountain arable land where farmland is returned to forests for planting. The pit was dug according to the plant distance of 1.3m to 1.7m, the width and depth of the pit were 33cm, and the soil fertilizer 45kg was applied to each pit. One to two seedlings were planted in each pit, pressed with fine soil and fixed with root water.

Field management: ploughing and weeding 3 times a year: the first time at the time of new leaves, the second time at 7: 8, and the third time before frost in late autumn and early winter. Combine with ploughing to cultivate the soil so as not to expose the flower roots to the ground.

Fertilization: 1-2 years after planting, it is the stage of plant setting, with more fertilizers such as human dung storage, plant ash, urea, potassium sulfate and so on. After planting for 2 or 3 years, more fertilizers such as animal manure, barnyard manure, cake fertilizer and calcium superphosphate should be applied every year before winter or early spring. "the Beginning of Summer" after each crop of flowers will be topdressing nitrogen, phosphorus, potassium compound fertilizer to provide nutrients for the following flowers.

Pruning: before sprouting in early spring, the top of the branch is cut off so that the lower part of the branch is gradually sturdy and can grow upright. The old withered branches and invalid branches should be removed from the larger flower stump, the vigorous ones should be cut lightly, and the weak ones should be cut heavily. Through pruning, the flower stump is trimmed into an umbrella shape, which is high and low around, so that the clumpy branches are exposed to the hammer wind and bear more flower branches.

Disease and pest control: the main wife of honeysuckle is brown spot, which can be sprayed with 65% Dysen zinc 500 times solution or 1% 1.5% 300 Bordeaux solution every 7 to 10 days, 2 times in a row. Insect pests are mainly aphids. Omethoate emulsion can be used to spray water 2000 times.
