Method of raising ormosia seedlings by cutting

Abstract

The invention discloses a method of raising ormosia seedlings by cutting. The method includes the steps of preparing cutting beds, to be specific, building the cutting beds in a greenhouse, providing each cutting bed with a plastic shed, mixing well fresh yellow soil, fine sand and nutrient soil proportionally to obtain cutting substrate, spreading the cutting substrate on the cutting beds, and sterilizing the cutting beds with potassium permanganate before cuttage; collecting cuttings, to be specific, using shoots which grow robust, are free of disease and pest damage and are already lignified, as cuttings, cutting flat the upper end of each stem, and cutting a 45-degree slope at the lower end of each stem; treating the cuttings, to be specific, soaking lower end cuts of the cuttings into composite rooting agent solution, and treating the shoots with sterilizing liquid for standby; performing cuttage, to be specific, inserting the cuttings into the cutting substrate, making sure the lower ends of the cuttings are in tight contact with the cutting substrate, and performing full irrigation; performing post-cuttage management, to be specific, keeping the interior of bow film at 20 DEG C to 28 DEG C under the humidity of 85% to 90% to make sure the cuttings and their leaves are glossy. The method has the advantages that rooting time is short, rooting rate is high, survival rate of seedlings is high and the method is suitable for popularization and application in production practice.

Description

technical field [0001] The invention relates to the field of cutting seedling raising, in particular to a method for red bean tree cutting seedling raising. Background technique [0002] Ormosia hosiei Hemsl.etWils, also known as Hubei red bean tree, rosewood, and flower palm wood, is an evergreen or semi-deciduous tree of the Papilionaceae Ormosia genus. It is a unique tree species in my country and is listed as a national II. Level key protection of wild plants. The red bean tree has a beautiful tree shape, dark green and verdant leaves, smooth and hard wood, and beautiful texture. It has extremely high timber, landscape and forest cultural values. Due to the high economic value of this tree species, the felling and utilization seriously exceed its planting and growth rate, resulting in an increasingly narrow distribution range and a gradual depletion of wild resources. In addition, red bean tree bare-root seedlings are often used for afforestation in production. Due to t...

Problems solved by technology

In addition, red bean tree bare-root seedlings are often used for afforestation in production. Due to the limitations of natural conditions and afforestation seasons, the survival rate and effectiveness of afforestation are not stable

The fruiting of red bean tree is late and unstable. Generally, it blooms and sets around 35 years, and enters the peak fruiting period after 50 years. After that, it usually blooms and bears once in 3-5 years. However, its ability of seed propagation and natural reproduction is poor. The shortage of seedlings seriously restricts the development scale of red bean trees

[0003] Therefore, in recent years, many researchers continue to explore the cuttings of red bean tree seedlings. Although some achievements have been made, there are still long rooting time, low rooting rate and low survival rate of red bean tree cuttings in the process of raising seedlings of red bean trees, which cannot be popularized in production practice. And other issues
