Embodiment

[0030] In December, after the seed collection is completed, for the seed-collecting mother tree with more than 4 rounds of first-level side branches, cut or saw all the first-level side branches from bottom to top step by step from top to bottom.

[0031] From bottom to top, at 20 cm from the trunk of the third or fourth round of side branches, saw the trunk obliquely at an angle of 45 degrees. When miter sawing the trunk, first cut a 10 cm saw cut from bottom to top, and then connect the saw cut from top to bottom.

[0032] All sawn side branches or main trunks should avoid dropping and retaining branches.

[0033] Among the reserved rounds of first-level side branches, cut or saw off the weak branches that are pressed, covered by upper branches, or covered by lower layers that are stronger and more evenly stretched.

[0034] Among the retained first-level side branches in each round, the annual main shoots are cut off, and 2 year-old side shoots are kept; in each round of s...

experiment example

[0041] Treatment group refers to the selection of clone plants in the seed orchard, using the method described in the application to carry out crown cutting, removal of apex, fertilization, auxiliary pollination; selection of the same clone plants without corresponding treatment, as a control group, compared, the results See Table 1.

[0042] Through Table 1, it is found that compared with the control plants, the tree height of the treated plants is reduced after 2 years, the seed-setting layer is reduced, the crown width is reduced, the fruiting amount in the inner chamber of the crown is increased, the new branches are thick, the tree body is rejuvenated, the flowering and setting amount is increased, and the labor intensity of seed collection is reduced. .

Abstract

The invention discloses a method for dwarfing and rejuvenating seed orchard big trees of masson pine and improving flower and fruit setting rate. The method comprises the steps of conducting crown cutting, tip removing, guiding retraction of a side tip in a lower layer, improving a light condition of a seed tree in the seed orchard, and conducting furrow digging and fertilization treatment on the seed orchard. According to the method for dwarfing and rejuvenation of seed orchard of masson pine and improving flower and fruit setting rate, through the steps of crown cutting, tip removing, guiding retraction of a lower side tip, and improving of a light condition of a seed tree in the seed orchard, an invalid inner chamber space ratio of non-fructification of the seed tree of the masson pine is lowered, and a fructification valid area is increased; meanwhile, flowing of nutrients and growth hormone of various kinds in the tree body towards a retained branch and reassignment of the nutrients and growth hormone are benefited, retaining of a growth branch in a lower layer, restoring of vitality of a tip, and germination of a bud are promoted, and material preparations for fructification is guaranteed by adding flowers and branch tips. The method for dwarfing and rejuvenating seed orchard big trees of masson pine and improving flower and fruit setting rate is simple and easy to operate, low in cost, and can be popularized in production management of ageing seed orchard of the masson pine.

Description

technical field [0001] The application belongs to the technical field of planting, and in particular relates to a method for dwarfing and rejuvenating large trees in a masson pine seed orchard and improving the rate of flower setting and fruit setting. Background technique [0002] Pinus massoniana (Pinus massoniana) belongs to Pinaceae (Pinaceae), Pinus (Pinus), subgenus Subgen.Pinus (Subgen.Pinus), and is an evergreen tree. In 17 provinces, autonomous regions, and municipalities directly under the central government in my country, it is the native tree species with the widest distribution, the largest area, a wide range of uses, and the highest degree of comprehensive utilization of the whole tree among coniferous tree species. Masson pine is a monoecious plant with different flowers. Like most pine tree species, its reproduction is mainly by seeds. The seed garden is an important base for the production of masson pine varieties. Most of the masson pine seed gardens in my c...
