Problems solved by technology

[0003] Ginkgo seedling raising methods mainly include four methods: sowing, tillering, cutting, and grafting. Sowing and breeding are beneficial to the breeding of new varieties, but the traditional method of sowing seedlings requires first storing the seeds in sand for a long time, and then soaking them to accelerate germination, and the germination rate is only low. It can reach about 50%, and the seedling period is long, which obviously increases the planting cost. Therefore, a method for sowing seedlings of ginkgo is needed

Embodiment 1

[0023] A kind of sowing seedling raising method of ginkgo, comprises the following steps:

[0024] (1) Seed preparation: select mature and complete ginkgo fruit, freeze-dry until the water content is 17-19%, quickly reduce the water in the ginkgo fruit, maintain the vitality of the germ, increase the gap of the seed coat, and promote the entry of nutrients and water. It is beneficial for seeds to break dormancy, accelerate seed germination, remove the peel, and obtain ginkgo seeds;

[0025] (2) Seed blanching: Before sowing, soak the ginkgo seeds in water at 0~2°C for 3 hours, take them out, mix the plant ash with iodized salt, the weight ratio of plant ash and iodized salt is 6:1, heat and stir-fry until The temperature is 52~54℃, turn off the fire source, add the soaked ginkgo seeds, stir fry quickly for 90~100 seconds, after low temperature and high temperature treatment, and the plant ash and iodized salt are rich in nutrients, so that the seeds are heated evenly and enhan...

Embodiment 2

[0039] A kind of sowing seedling raising method of ginkgo, comprises the following steps:

[0040] (1) Seed preparation: select mature and complete ginkgo fruit, freeze-dry until the water content is 17-19%, quickly reduce the water in the ginkgo fruit, maintain the vitality of the germ, increase the gap of the seed coat, and promote the entry of nutrients and water. It is beneficial for seeds to break dormancy, accelerate seed germination, remove the peel, and obtain ginkgo seeds;

[0041] (2) Seed blanching: Before sowing, soak the ginkgo seeds in water at 0~2°C for 3 hours, take them out, mix the plant ash with iodized salt, the weight ratio of plant ash and iodized salt is 6:1, heat and stir-fry until The temperature is 52~54℃, turn off the fire source, add the soaked ginkgo seeds, stir fry quickly for 90~100 seconds, after low temperature and high temperature treatment, and the plant ash and iodized salt are rich in nutrients, so that the seeds are heated evenly and enhan...

Embodiment 3

[0055] A kind of sowing seedling raising method of ginkgo, comprises the following steps:

[0056] (1) Seed preparation: select mature and complete ginkgo fruit, freeze-dry until the water content is 17-19%, quickly reduce the water in the ginkgo fruit, maintain the vitality of the germ, increase the gap of the seed coat, and promote the entry of nutrients and water. It is beneficial for seeds to break dormancy, accelerate seed germination, remove the peel, and obtain ginkgo seeds;

[0057] (2) Seed blanching: Before sowing, soak the ginkgo seeds in water at 0-2°C for 4 hours, take them out, mix plant ash with iodized salt, the weight ratio of plant ash to iodized salt is 7:1, heat and stir-fry until The temperature is 52~54℃, turn off the fire source, add the soaked ginkgo seeds, stir fry quickly for 90~100 seconds, after low temperature and high temperature treatment, and the plant ash and iodized salt are rich in nutrients, so that the seeds are heated evenly and enhance th...

Abstract

The invention mainly relates to the technical field of plantation and discloses a gingko sowing and seedling raising method. The method includes: seed preparation, seed blanching, seed soaking, seed germination accelerating, seed sowing, after-sowing management and acclimatization and transplantation. The method is simple in operation, seed germination accelerating time is shortened to 7-8 days, seed germination is realized 5-6 days after sowing, the germination rate is 67.3%, planting efficiency is evidently improved, and economic income is increased by 11.7%. Ripe gingko nuts are picked and subjected to freeze drying to keep germ activity, permeation of nutrients and water is promoted due to increase of seed coat gaps, and seed dormancy can be broken beneficially to accelerate seed germination. Blanched seeds without outer seed coats are soaked in soaking liquid which contains various components, seed pH can be increased, the ginkgolic acid content of seeds is reduced, rich nutrients are provided and quickly permeate into the seeds to promote seed germination, and accordingly the seed germination rate is increased.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for sowing and raising seedlings of ginkgo. Background technique [0002] Ginkgo, also known as ginkgo tree, Gongsun tree, ginkgo tree grows slowly and has a very long life span. It is the old birthday star in the tree and has great ornamental, economic and medicinal values. Anti-fire, anti-toxic gas, listed as China's four major longevity ornamental tree species (pine, cypress, locust tree, ginkgo), ginkgo fruit can inhibit bacteria and kill bacteria, eliminate diseases and coughs, resist waterlogging and insects, stop turbidity, reduce stool, reduce Cholesterol, protection of cardiovascular and cerebrovascular, ginkgo is more and more popular among people. [0003] Ginkgo seedling raising methods mainly include four methods: sowing, tillering, cutting, and grafting. Sowing and breeding are beneficial to the breeding of new varieties, but the traditional method...
