Problems solved by technology

[0003] Five-needle pine is an evergreen coniferous tree with slow growth, short leaves and dense branches, elegant posture, beautiful tree shape, and high ornamental value. It is not only suitable for garden decoration, but also an important tree species for potted plants or bonsai. But the five-needle pine of Dabie Mountain grows on shady and semi-shady slopes, with less fruit and more grains. In addition, the number of five-needle pine in Dabie Mountain is extremely rare, and the cost of protecting saplings is also very expensive.
In recent years, more and more ecological protection scholars or breeding experts have begun to pay attention to and carry out the problem of raising seedlings of Dabie Mountain five-needle pine. Pinus pine seeds are ripe every two years. They bloomed and bear fruit in the previous year, only the size of a thumb, and grow to maturity in the next year. The mature cones are harvested in autumn. After a series of treatments, the seeds are collected for seedling cultivation; but most of them use conventional Or when the temperature-changing seedling raising method was used to breed Dabie Mountain five-needle pine, it was found that the germination rate of this seedling raising method was only about 50%, and the five-needle pine seeds needed to be cracked in the process. Currently, some cracking machines on the market can only do a small amount of manual work. Some of them have a low rate of broken shells, some of them are more damaged and have a higher rate of broken shells, which are easy to cause damage to the seeds of five-needle pine and affect germination.

Abstract

The invention discloses a breeding method based on Japanese white pine seedlings in Ta-pieh Mountains. The breeding method is characterized in that the breeding method comprises the following steps: (1) seed selecting and pretreating; (2) soil selecting and preparing: preparing soil in a Japanese white pine nursery, wherein soil in the nursery is composed of humus soil containing minced meat, wetsand and root soil for the growth of the Japanese white pine, and applying enough base fertilizer; (3) placing ceramsite and the Japanese white pine seeds into a poultry feather removal machine together to carry out shell-breaking in batches on the Japanese white pine seeds; (4) germination accelerating: selecting plant ash, amino acid and garlic powder, pouring the plant ash, the amino acid and the garlic powder into a container filled with distilled water to carry out seed soaking for the first time, with the seed soaking temperature being 35-55 DEG C and the seed soaking time being 2-3 days; and then putting the Japanese white pine seeds into aqueous solution containing brown sugar, bamboo salt and vinegar to carry out seed soaking on the Japanese white pine seeds for the second time, followed by putting the Japanese white pine seeds into mountain spring water with the temperature of 3-5 DEG C to carry out seed soaking for the third time; and (5) fishing out the soaked seeds for sowing. The breeding method has the advantages of high emergence rate, strong seedling vigor and strong resistance.

Description

technical field [0001] The invention relates to a breeding method based on Dabie Mountain five-needle pine seedlings. Background technique [0002] Different seeds have different life spans. For example: willow seeds only have 12 hours, peanuts can live for 1 year, wheat and rice can generally live for 3 years, and cabbage and broad beans can live for 5-6 years. Normal seeds store enough nutrients needed for seed germination in the cotyledon or endosperm, and shriveled seeds often fail to germinate due to lack of sufficient nutrients. After most seeds are formed, they temporarily fail to germinate even under favorable conditions, a phenomenon known as dormant plant seed germination. The main reasons for forming: the one, seed coat disorder. The seed coat of some seeds is thick and hard, or a waxy layer or cuticle is attached to the seed coat, making it impervious to water, airtight or mechanically hindering the embryo. The second is that some fruits or seeds contain subs...
