High-altitude layering propagation technology for aleurites moluccana tree

Abstract

The invention relates to a technology for propagating an aleurites moluccana seedling by high-altitude layering. According to the technology, an operating method comprises the following steps of: selecting branches of which the sizes are similar and the growth conditions are excellent from the aleurites moluccana tree which has more than 4 age from March to October in every year; performing girdling on the stem bases of the selected branches, wherein the width is about 2 to 4 centimeters, and a cortex layer and a cambium are scraped completely; coating a growth regulator with appropriate concentration at the upper ends of incisions; making a wet matrix into a mud pie, covering wounds with the mud pie, wrapping the outside of the mud pie by using a plastic film, and binding by using a packing rope; and checking the humidity of the mud pie during layering rooting, and when the humidity is low, replenishing moisture by an injection method to keep the humidity of soil, wherein after the girdling is performed, roots are grown at the wounds a month later; and cutting the layering for transplant when a large quantity of root systems are formed two or three month later.

Description

technical field [0001] The invention relates to a technical method for plant propagation, which is a method for asexually propagating seedlings of chestnut trees. Background technique [0002] Chestnut (Aleurites moluccana) originated in tropical and subtropical regions, and is a tall evergreen tree with wide leaves. The oil content of its kernel is as high as 64%-68%, and the protein content is 21.6%. Chestnut kernel oil is a high-quality raw material for biodiesel production. The protein content of the cake obtained after oil extraction is as high as 40% to 50%. After detoxification treatment, it can be processed into high-quality concentrated feed or directly fermented to produce high-efficiency and high-quality organic compound Fat. Chestnut seed shells are hard and thick, accounting for about 60% of the weight of the seeds. They contain oil and have a calorific value of 4370 kcal / kg. They can be used as fuel instead of coal. Therefore, chestnut is a high-efficiency en...

AI Technical Summary

Problems solved by technology

The traditional reproduction of chestnut is sexual reproduction, that is, using seeds to sow seedlings and transplant them. Due to the long dormant period, low germination rate, irregular seedling emergence and long seedling time of chestnut seeds, it takes 2-3 hours from sowing to seedling emergence and transplanting. Years, and the growth and development of seedlings are not uniform, and the yield level varies greatly

In addition, the first fruit-bearing period of the seedlings of the chestnut tree is long, and it takes 5-8 years. These problems are the bottlenecks that limit the development of the industrialized planting of the chrysanthemum tree.
