Embodiment Construction

[0019] A kind of thin-shell hickory seed high temperature accelerating germination turnover box seedling raising method of the present invention, it comprises the following steps:

[0020] a) Seed pretreatment: soak the seeds with 40-60ppm gibberellin solution for 8-10 days, then wash the seeds with water for later use;

[0021] b) Turnover box technology for germination: place the soaked and cleaned seeds in the seed turnover box, the thickness of the seeds is preferably 6-10cm, and cover with a layer of soaked gauze;

[0022] c) Germination at high temperature: place the turnover box holding the seeds in an environment with a temperature of 35-45°C and a humidity of 50-70% to germinate, and spray the seeds with a fungicide solution every 6-7 days.

[0023] d) Sorting and sowing: pick the cracked seeds in the step c) at any time, sow them into the seedling box equipped with a pre-prepared substrate, place them in an environment of 15-25° C., and moisturize them regularly. Wh...

Abstract

The invention provides a high-temperature stratification turnover box seedling-raising method for seeds of carya illinoensis. The method comprises the following steps of: a) pretreatment of seeds; b) stratification turnover box technology; c) high-temperature stratification; and d) sorting and seeding. By the method, the germination rate of seeds of carya illinoensis is improved, and up to 90 percent; and the seeding rate is lowered, the conventional autumn seeding or sand storage stratification is replaced by a turnover box high-temperature stratification method, and the germination stage of seeds is obviously shortened. The method has the advantages of shortening the germination stage of seeds of carya illinoensis by adopting the high-temperature treatment method, enforcing seeds of carya illinoensis to bud quickly, highly efficiently and orderly and improving the seedling emergence rate of seedlings of carya illinoensis, and is simple in operation and low in cost.

Description

technical field [0001] The invention relates to a method for accelerating germination of pecans, in particular to a method for accelerating germination of pecans with thin shells. Background technique [0002] Thin-shelled hickory (caray illinoensis), also known as American hickory, long hickory. It is a plant of the genus Hickory in the family Juglandaceae. Its kernels are nutritious and delicious, containing 71.7% oil, 5.4% carbohydrates, 4.6% total sugar, 11.4% protein, vitamin A130 IU, and vitamin B10.86 mg / 100 g. This tree species is a large deciduous tree with a height of 20-30 meters. It can reach 55 meters in the Mississippi River Basin in the United States. Good material for sleepers, construction, high-grade furniture and flooring. Thin-shelled hickory trees grow quickly, are resistant to water and humidity, and are good landscaping and afforestation trees. [0003] Now it has become one of the important dried fruit tree species in the world, distributed in mor...
