Barley seedlings can be harvested three times. Usually, it can be harvested three times in the process of barley seedling production as long as it is harvested for about 20 days under suitable environmental conditions.

It usually takes about 8 days for barley seedlings to grow to 8~ 10 cm, and they can be harvested and eaten. When harvesting, cut it flat from the root with scissors.

The sowing time of barley seedlings is about 5 days. Spread the paper soaked in water flat on the seedling tray, and then spread the germinated barley seeds evenly on the paper. 250g of dried barley seeds can be sown in 2-3 trays of 30cm× 25cm seedlings. After the seeds are sown, buckle a seedling tray of the same size on it to keep the humidity. At the same time pay attention to the ventilation of the seedling tray.

In the process of barley seedling raising, the germinated seeds are evenly wetted 1~2 times a day with a watering can, and the degree is that the paper at the bottom of the tray is soaked without water. Families can spray it for different times every day according to different planting environments and seasons, usually 4 times in summer and 1~2 times in winter.

After seedling urging, when the barley seedlings grow white buds with a height of 1 cm, light is applied. During this period, the daytime temperature is about 25℃ and the nighttime temperature is about 15℃. The light can be natural light. When the high temperature and light are too strong in summer, don't put it on the balcony, and don't draw curtains to shade it. After seeing the light, spray barley seedlings with a watering can every day until the bottom paper of the seedling tray is wet.
