Propagation method for planting root segments of vine campsis grandiflora

Abstract

The invention provides a propagation method for planting root segments of vine campsis grandiflora. The method comprises the following steps: (1) digging out campsis grandiflora plants, which have enter a dormant period after leaves fall off in autumns and winters and surrounding root systems thereof; and (2) shearing the root systems of the campsis grandiflora plants dug out in the step (1) into 2-3 cm long root segments by using scissors; immediately scattering the root segments on a seedbed or a target green area or planting the root segments in a nutrition pot in bunches; covering a nutrition soil on the root segments; profoundly watering the nutrition soil in time, wherein the nutrition soil is required to be loose and fecund and have no pest and weed; and the root segments sprout and grow to new plants in March and April of next spring. As the root segments of the campsis grandiflora in the dormant period are selected as planting materials for root segment planting propagation, the propagation method has the advantages of simple and easy operation, low cost, easy rooting and high propagation survival rate (more than 95 percent).

Description

Technical field [0001] The invention relates to a method for propagating a vine plant, in particular to a method for propagating a vine plant Campsis. Background technique [0002] At present, the breeding methods of Campsis grandiflora (Thunb.) K. Schum. are as follows: (1) Seed reproduction: Collect mature seeds in October of that year, dry them in the sun, and sow in the spring of the following year. Nursery; (2) Cutting propagation: in spring or rainy season, suitable for Beijing area from July to August, cut solid and thick branches, each 10-16cm long, and ensure that there are 2 to 3 buds on each branch , The cuttings are placed on a sand bed and covered with glass to maintain sufficient temperature and humidity; generally the temperature is 23~28℃, and the roots can be taken 30 days after insertion, and they can be moved into the fields in the spring of the following year. In warm areas in the south, they can be used in spring. Cut off the new technology of the first year...

Problems solved by technology

[0003] Propagation by seeds is difficult to bear fruit, the conditions for seed germination are strict, and reproduction is relatively difficult; propagation by cuttings is difficult for Lingxiao to take root, the time is long, and the reproductive success rate is not high, generally below 40%; layering or division propagation, The operation of both is difficult and the reproduction coefficient is low
