Sexual breeding method for sumac seeds

Abstract

The invention provides a sexual breeding method for sumac seeds. The sexual breeding method comprises steps of seed selection, seed nursery, land preparation, broadcasting and seedling nursery. In the seed selection step, after sumac seeds are selected, waxes on the surface of the sumac seeds are removed; the seeds are immersed and rubbed in hot water at the temperature of 65 DEG C until the waxes are fully removed; full and unbroken seeds are selected; in the seed nursery step, a bamboo basket is placed on the upper part of a bottomless wooden barrel; the seeds are placed in the bamboo basket and then the bamboo basket is covered with straws and placed in a warm and wind-shielding place; the seeds are sprayed once every day by warm water at the temperature of 35 to 45 DEG C; the seeds are elutriated each two days; the seed case breaks off after 11 to 13 days; in the land preparation step, a sand land is selected; the sand land is well prepared in the previous autumn and winter; in the first ten-days of February the year, seedbeds are prepared; in the seed broadcasting step, seeds are scattered on the land; 19 to 21 kg of seeds are sowed on each mu of land; then soil with the thickness of 1 cm is laid on the seeds; and the seeds sprout after one month. By the use of the method, sumac seeds can be bred on a large scale and seedlings can be nursed in batches, so sumac seed breeding efficiency can be improved and raw lacquer output can be improved; raw lacquer can be conveniently harvested; and objective economic benefits can be brought to sumac farmers.

Description

technical field [0001] The invention relates to the technical field of plant seed propagation, in particular to a method for sexual propagation of sumac seeds. Background technique [0002] Sumac is widely distributed in my country and is a very important economic tree species. The raw lacquer (juice) cut from its bark is an excellent natural paint, which has the advantages of acid resistance, alkali resistance, high temperature resistance, wear resistance, insulation, strong adhesion, environmental protection, etc., and is known as the "king of paint". It is known as an important raw material for modern industry, agriculture, national defense, science and technology, and civilian use. Due to the excellent performance and irreplaceability of raw lacquer, the demand for raw lacquer in the market is in short supply. [0003] There are four kinds of lacquer trees that produce seeds in the Qinba Mountains, namely big wood lacquer, small wood lacquer, eight feet high, and big r...

AI Technical Summary

Problems solved by technology

[0003] There are four kinds of lacquer trees that produce seeds in the Qinba Mountains, namely big wood lacquer, small wood lacquer, eight feet high, and big red robe. In the past, birds mostly ate the seeds, digested the pulp and waxy layer on the surface, and the seeds were excreted with bird droppings. After encountering a suitable environment for germination and breeding, some local farmers transplanted wild seedlings to the ditch, roadside, and field near their residences. These propagation methods have the disadvantages of small and scattered lacquer trees, which are not convenient for raw lacquer harvesting, etc. question
