Key points of cultivation and management of honeysuckle

1. Ploughing, weeding and soil cultivation

After the seed seedlings or asexual propagation seedlings of Flos Lonicerae are fixed, ploughing and weeding should be carried out in time in the annual growing season. When planting in cold areas in winter, the soil should be cultivated in the rhizosphere combined with loose soil before freezing, so as to prevent the root system from freezing damage.

two。 Fertilization, drainage and irrigation

Combined application of rotten stable fertilizer and superphosphate in early spring or late autumn. The method of ring fertilizer can be used when fertilizing, that is, a ring-shaped ditch is opened around the plant, and the soil is filled with fertilizer. In addition, when there is flower bud differentiation before flowering, foliar spraying ammonium dihydrogen phosphate (NH4H2PO4) and so on. Where there are conditions, if drought occurs in early spring or flowering, it should be properly irrigated, and when Rain Water is too much in the rainy season, it should be drained in time to prevent stagnant water from causing falling flowers or rupture of young buds.

3. Shaping and pruning

Honeysuckle has strong natural regeneration ability and many branches. Shaping and pruning is beneficial to cultivate sturdy trunk and main branches, make its branches upright in clumps, good ventilation and light transmission, increase yield and enhance disease resistance. Plastic surgery is when the plant is about 30 cm after planting, cut off the top tip, remove the apical dominance, and promote the lateral bud to germinate into branches. Among the lateral buds, five stout branches were selected as the main branches, and the rest were cut off. After that, the primary lateral branches from the main branches were retained with 6 Mel 7 pairs of buds, and the top was cut off; and from the secondary lateral branches from the primary lateral branches, 7 pairs of buds were retained and the top was cut off. After the step-by-step shaping mentioned above, the honeysuckle plant can be upright, the branches are layered, and the ventilation and light transmission is good.

In addition to plastic surgery, the cultivation of honeysuckle should also be combined with winter and growing season pruning measures to adjust the plant. Winter pruning is to cut off diseased branches, weak branches and withered branches from Frosts Descent to before freezing every year; pruning in the growing season is to cut off the top of the branches after the flowers are cut off to promote the flowering mother branches to produce new branches early and bloom for the second time. Because the flower bud differentiation of honeysuckle is only carried out on the newly produced branches, although the flowered branches can continue to grow, they can not bear flowers again, and only the new branches on the original mother branches can form buds and bloom.
