Method for unshelling and extracting seeds of castanopsis hystrix fruits

Abstract

The invention discloses a method for unshelling and extracting seeds of castanopsis hystrix fruits. The method comprises the following steps of: collecting fruits, piling and retting the fruits, unshelling and separating. The method is characterized in that castanopsis hystrix fruits are collected from trees and are placed into bags, drug is sprayed onto the bags, the bags are placed indoor and piled and retted for 4-8 days, after shells of part of fruits are naturally cracked, the fruit unshelling machine designed by the inventor is used for carrying out mechanical unshelling and extracting the seeds, pure castanopsis hystrix seeds are obtained, and large-scale sowing requirement is met. The method disclosed by the invention overcomes the defects of the traditional processing method that fruits with lower maturity are easy to be faded by sunlight and can not be cracked and seed yield is reduced as the fruits are dried for 2-3 days in the sun and the seeds are tapped after involucre is cracked in the traditional processing method; and the method disclosed by the invention also solves the technical problems that firstly dropped seeds are subjected to solarization in the sun and are easy to lose water and crack and germination rate is reduced, quality of the extracted seeds, the seed yield, the germination rate and working efficiency are improved, and advantages are created for rapidly propagating rare trees, thus the method disclosed by the invention has better economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of plant fruit treatment, and relates to a method for shelling and seeding red cone fruit. Background technique [0002] Red cone (Castanopsis hystrix) is an evergreen tree of the Fagaceae Castanopsis genus. It is distributed in Guangxi, Guangdong, Hainan, Yunnan, Guizhou, Hunan, Jiangxi, Fujian and other provinces, as well as Medog County in Tibet. The central distribution area is in Guangxi The southern hilly area below 700m above sea level. It grows fast, has strong germination, dense branches and leaves, is more shade-tolerant, and has good mixed growth performance. It is the best tree species for mixed afforestation with pine, fir or other broad-leaved trees in the hilly areas of South China. Red cone material is excellent, the wood is hard and corrosion-resistant, the heartwood is large, brownish red, and the sapwood is light red. , Vehicles, craft carving, building decoration and other high-quality ...

AI Technical Summary

Problems solved by technology

However, the seeds of the red cone are covered with a husk with staghorn thorns. After the fruit is collected, it needs to be processed to obtain pure seeds. The traditional processing method is to put the fruit in the sun for 2 to 3 days. After the involucre cracks, knock out For seeds, this method is easy to crack for fruits with high maturity, while fruits with low maturity are easy to be sun-dried by the sun, unable to crack, and the seed yield is reduced. , the husks exposed to the sun become dry and brittle, brittle after being knocked, mixed with the seeds, and the collection of seeds is very inconvenient
