1、 Preservation method

The common preservation method of Ginkgo seeds is sand storage stratification, which is conducive to the growth and development of seed embryos, and the germination rate of seeds is also high. The specific operation methods are as follows:

1. Clean the seeds with water, spread them out and dry them for 3-5 days, and remove the sand with water content less than 5% according to the proportion of half and half, preferably 5-10cm. First put a layer of sand, then put a layer of seeds, and finally cover the sand

2. When the sand is stored for about 3-5 days, you need to turn it over and turn it over again in the last week to avoid moldy seeds

2、 What is the survival probability

Using this method, the germination survival rate is relatively high, which is about 15% higher than the general survival rate. Generally, the survival rate of Ginkgo seeds is not very high, only about 70%. However, it is not just seeds that affect the survival rate. The planting time and method will also affect the survival rate. It is best to carry out it in spring and autumn. It is necessary to promote germination before planting, so the survival rate will be relatively high
