A labor-saving elderberry shaping and pruning method

Abstract

The invention provides a labor-saving elderberry pruning method which comprises the following steps: in the first year, selectively planting elderberry seedlings in early spring, stumping from the stem base, and stumping again after leaf falling; in the second year, thinning branches after branches grow, remaining 6-8 long branches, and remaining 4-5 long branches during winter pruning; in the third year, thinning branches after branches grow, remaining 4-5 annual growth branches and 8-10 current year growth branches, remaining 8-10 current year growth branches during winter pruning, and thinning last year growth branches, autumn shoots and lateral branches; and in the fourth year, thinning branches after branches grow, remaining 8-10 last year growth branches and 8-10 current year growthbranches, remaining 8-10 current year growth branches during winter pruning, thinning the last year growth branches, autumn shoots and lateral branches, and pruning according to the operations in thefourth year each year in future. The labor-saving elderberry pruning method provided by the invention is simple, easy to operate, has time-saving and labor-saving effects and is favorable for popularization, the elderberry can enter a high yield period in advance, and high and stable yield of elderberry fruits can be realized.

Description

technical field [0001] The invention relates to the technical field of economic forests, in particular to an elderberry pruning method. Background technique [0002] Elderberry ( Sambucus Linn.) is a deciduous shrub or small tree of Caprifoliaceae, a rare herb. There are more than 20 species of this genus distributed all over the world, widely distributed in temperate and subtropical zones, and 5-6 species in my country. Many species of elderberry plants have extremely high food value, medicinal value, ornamental value, and beauty value. "Tang Materia Medica" records that elderberry is famous for its bone-setting effect, enjoys a very high status among the people, and is known as the "medicine box". [0003] Elderberry is a new woody oil-bearing plant, and studies have confirmed that the oil content of its fruit reaches 35% to 44%. The essential fatty acid content in elderberry oil is 87.17%, which is higher than that of soybean oil (62.8%), sunflower oil (73.03%), and ...

Problems solved by technology

At present, resources are not fully utilized, only medicinal use is more, and other comprehensive utilization is rare. The common cultivation mode is to rely on natural harvest, and the management is backward, resulting in scattered elder tree shape, severe years of big and small, and unstable yield.

In the prior art, there is a theory of elderberry pruning method, which adopts multi-dry bush-shaped or single-dried plants, and keeps the main trunk or main branch; although the yield is somewhat improved, the pruning method is complicated, labor-intensive and time-consuming

The internal branches of multi-stem shrubs are difficult to trim; the selection of main branches and side branches of single-stem plants is difficult to grasp, especially the main branches. Once the wrong selection will affect the yield and tree shape of the whole plant
