In the summer of 1975, the brigade of Xujiacun, Xiaoyeyuan and Maojiagou in the kingly commune of Baoji County adopted the method of seed soaking and germination. Wheat harvest in June after planting, cultivating a total of mu per year can be used for broadleaf rootstock seedlings received 10 to 150,000, with early emergence, emergence and more, provincial and provincial advantages. A, soaking seed germination. Seeds before sowing in clear water soak for a whole day and night, the seeds swell out after water swelling, rinse with water, filter dry, into a clean plastic bag germination 1 to 2 days, the seed coat rupture white, you can sow.
