Methods of cultivating rootstock seedlings of jujube or sour jujube

Cultivation of jujube rootstock seedlings: ⑴ seeds were seeded with seeds, and the fruits with high kernel content and full maturity were selected in autumn, and the fruits were heaped for 4 to 5 days (the heap temperature was not more than 65 degrees). After the flesh was softened, the flesh was broken, washed and washed with water, and the seeds of jujube (sour jujube) were dried in the sun. The jujube seed (wild jujube seed) can be sown immediately in autumn or sown in the following spring after stratification. Use 10 to 12.5 kg of nuclear per mu. ⑵ seeds are sown. First break the nucleus to remove the kernel, without stratification, soak in water before sowing, 1 to 2 days, after the kernel is fully absorbed, sow the seeds directly. Use 2 kg of kernels per mu.
