Embodiment 1

[0016] A kind of method for accelerating germination in winter of pecan seed of thin shell, comprises the following steps:

[0017] (1) Seed preparation and screening: Collect healthy and plump seeds after the hickory nuts are fully mature, and remove broken and shriveled seeds; for seed screening, a seed screening box or a seed blower can be used to remove unfulfilled particles and other sundries.

[0018] (2) Pretreatment of seeds: Soak the selected seeds in water with a temperature of 0°C for 2 hours, then with water with a temperature of 15°C for 1 hour, and finally with water with a temperature of 35°C for 1 hour; Change the soaking water of the seeds every 30 minutes;

[0019] (3) Soak the seeds in chemical liquid: soak the seeds after step (2) in air-dry with 98% concentrated sulfuric acid for 3 minutes, wash them with water after soaking, and soak them in 0.5% potassium nitrate solution for 12 hours. Spare for sterilization;

[0020] (4) Physical treatment of seeds: ...

Embodiment 2

[0023] A kind of method for accelerating germination in winter of pecan seed of thin shell, comprises the following steps:

[0024] (1) Seed preparation and screening: Collect healthy and plump seeds after the hickory nuts are fully mature, and remove broken and shriveled seeds; for seed screening, a seed screening box or a seed blower can be used to remove unfulfilled particles and other sundries.

[0025] (2) Pretreatment of seeds: Soak the selected seeds in water with a temperature of 5°C for 2.5 hours, then in water with a temperature of 20°C for 1.5 hours, and finally in water with a temperature of 40°C for 1.5 hours; During the process, the soaking water of the seeds is changed every 30min;

[0026] (3) Soak the seeds in chemical liquid: soak the seeds after step (2) in air-dry with 98% concentrated sulfuric acid for 4 minutes, wash them with water after soaking, and soak them in 0.5% potassium nitrate solution for 24 hours. Spare for sterilization;

Abstract

The invention discloses a winter germination-accelerating method of apocarya seeds. The winter germination-accelerating method comprises the steps of firstly immersing the seeds in water at three different water temperature ranges; then carrying out chemical solution treatment by using concentrated sulfuric acid and potassium nitrate solutions and physical treatment by using an electromagnetic constant magnetic field; and finally carrying out germination-accelerating culture in sealed illumination at intervals. Through combined treatment of the above three manners, a germination time of the seeds is greatly shortened, rate of germination is increased, and uniformity of seedlings has greater improvement than that in direct sowing without accelerating germination. The winter germination-accelerating method has very high application values.

Description

technical field [0001] The invention relates to the planting technology of pecan, in particular to a method for accelerating germination of pecan seeds in winter. Background technique [0002] Thin shell hickory is a world-renowned high-grade dry fruit, oil tree species and excellent tree species for both wood and fruit. It is native to the United States. This tree species has high economic value, good landscaping and beautification effects, good wood quality, straight trunk, solid material, and fine texture. , high elasticity, not easy to warp, is an excellent material for making furniture. Moreover, the nut shell is thin and easy to peel, the kernel is thick, rich in fat, and has a sweet taste. It is a raw material for dried fruit and oil extraction. In addition, it is resistant to water and humidity, and is suitable for planting along rivers, around lakes and in plain areas, and can be used as street trees and shade trees. [0003] The rootstocks for grafting hickory nu...
