Planting Techniques:

 

In the first ten days of January of the following year, the seeds were soaked in warm water at about 30°C for 24 hours, and then taken out for sand mixing. Choose high dry terrain, sunny leeward, good drainage, and loose soil to dig a pit with a width of about 1 meter and pit seed to kill underground pests. The soil preparation should be fine, broken, and leveled to facilitate the management of planting and later water and fertilizer. The depth of the pit is 60 to 80 cm. In principle, it is above the groundwater level and below the frozen soil layer. The length of the pit depends on the number of seeds. First spread a layer of coarse sand on the bottom of the pit, and then spread a layer of 5 to 10 cm thick moist fine river sand. Mix the seeds and wet sand in a ratio of 1:3 and pile them in the pit. The humidity of the sand is 60 of the saturated water content. % To 80%, that is, hold into a ball, loosen it is appropriate. When the seeding sand is placed 20 cm above the ground, it is covered with a 5 cm thick layer of coarse sand, and then covered with soil to form a ridge, with a grass in the center of the pit to facilitate ventilation. Drainage ditch is dug around the pit to prevent accumulation of water. Check regularly during storage to prevent the seeds from fever and mildew. After the soil has thawed in mid-March, pour the seeds to a place leeward to the sun, and appropriately add water for warming and accelerating germination. When the seeds are 1/3 exposed white, they can be sown, and the layer accumulates to accelerate germination.
