Arbor type weigela florida thickening and trunk strengthening method

Abstract

The invention discloses an arbor type weigela florida thickening and trunk strengthening method. The method comprises the steps of (1) carrying out trunk setting processing of weigela florida seedlings, wherein only the thickest and strongest coppice shoot of each weigela florida seedling is reserved, and pinching and trunk setting are carried out on main branches; (2) pruning the weigela florida seedlings, wherein the sprouts and branches, under 50 cm, of the base portions of main branches are all pruned away in the very year when the trunk setting is carried out on the weigela florida seedlings, pinching processing is carried out on first level branches above 50 cm when the first level branches grow to 1.0 m, cutting-back processing is carried out on the first level branches growing to 1.5 m, and mentioned operation is repeated for twice or three times; in a similar way, carrying out pinching and cutting-back processing on corresponding branches in the second year, the third year and the fourth year respectively, so that thickening and trunk strengthening operation is completed. According to the arbor type weigela florida thickening and trunk strengthening method, the lignification degree of the seedlings is improved, the height-diameter ratio is reasonable, the branch breaking rate of lateral branches can be reduced by more than 95 percent, the lodging rage can be reduced by more than 98 percent, the commodity cycle can be shortened by more than two years, economic effects are improved, and the method also has the advantages that operation is easy, convenient and feasible, low in cost, and the method is easy to apply and popularize.

[0001] technical field

[0002] The invention relates to a method for thickening and drying arbor-type brocade flowers, belonging to the technical field of nursery stock cultivation methods. Background technique

[0003] Weigela florida (Weigela florida), a shrub of the genus Weigela in the Lonicera family. The plant height is generally 1.5m, the crown width is 1.5m, the branches are spread out, and the tree shape is relatively cylindrical. May-June. Jindaihua has dense branches and leaves and bright colors. It is the main early spring flowering shrub in North China in garden application. After many years of research on the introduction and cultivation of Lunshan flowers and trees in Jurong City, the shrub-like Jindai flower has been cultivated into an arbor-shaped tree. The arborized Jindai flower has been cultivated for many years, the trunk is upright and straight, and the thickness of the trunk and the width of the crown have increased significantly. Large, with a high...
