1, seed selection: use new seeds of the current year with full particles, uniform size, integrity, strong germination potential and germination rate of over 95%.
2. Disinfection: Disinfect the seeds with 0. 1% bleaching powder aqueous solution for 2 minutes, and then rinse them with clear water.
3. Soaking seeds: soaking seeds before sowing to accelerate germination can shorten the germination period and growth cycle. Especially in the cold season, it is necessary to soak seeds to accelerate germination. Soaking seeds can be done with water at 30 ~ 50℃, and the water temperature is lower in warm season and higher in cold season. According to the situation of seeds, the seeds are diluted 200-300 times with probiotics from Yifuyuan sprouts and soaked for 4-8 hours, so that the seeds are fully expanded and then taken out.
4. Germination accelerating: The soaked seeds fished out are disinfected with 84 disinfectant for 2 minutes, washed with clear water 1 time, and placed directly in a germination accelerating tray (with holes at the bottom) to accelerate germination for about 2 days (it takes about 3 days outside the machine). Pay attention to heat preservation, moisturizing and shading. The appropriate temperature for accelerating germination is 24-26 degrees, and 6 hours of watering 1 time is set according to the dry humidity of seeds. It is advisable to observe the seed growth to 0.5- 1CM in time.
5. Sowing: When the peanut bud grows to 1.5-2CM, plant buds immediately. The hydroponic plug and bud basket were disinfected with 84 disinfectant and washed with clean water. Seeding is carried out twice, and the first time, try to select the seedings with standard root length; If the roots are slightly shorter, the seeds can be planted for the second time (try to make the roots of peanut seeds planted at one time the same length). Note: When planting seeds, pay attention to the peanut bud root (the part protruding between the stem and the root), so that the root must protrude above the hole. If it leaks to the lower part of the hole, it will cause the peanut bud to grow downward. Put the sown plug into the seedling basket in turn.
6. Irrigation: After sowing, water is injected into the seedling basket (the ratio of sprout probiotics to water is1:300) to the top plane of the plug, and peanuts that are not sprouted or moldy are picked out during this period. The requirement of water level is not to overflow the hydroponic plate as the standard, and the roots can absorb water. After one-time irrigation, peanut bud stopped watering during its growth to prevent peanut bud from opening its petals. If the head of peanut bud inside the peanut bud machine is very dry, you can manually change the water once.
7. temperature. The optimum temperature for the growth of peanut bud cuisine is 24 ~ 28 degrees. The maximum temperature shall not exceed 30 degrees, and the minimum temperature shall not be lower than 22 degrees. Strengthen ventilation in summer; Peanut bud prefers carbon dioxide to oxygen during its growth, so it is necessary to close the upper and lower air intake holes and exhaust holes in the machine. Moreover, the humidity should not be too high. According to the humidity inside the machine (a hygrometer should be installed when conditions permit), moisture should be removed regularly, and the exhaust opening should be closed at ordinary times. Strengthen heat preservation in winter, and it can be produced in all seasons.
8. Harvest. Take the hydroponic plate out of the box directly, and remove the roots on the back of the plug with a knife or shovel to harvest. Generally, dishes can be served in 7 days. Sterilize baskets and trays for next use.
9. Generally, the output ratio of peanut bud is1:5. Vegetables that grow to 17 cm in length in peanut bud are generally 6-7 kg. Generally, the growth temperature should not exceed 28 degrees. If it is higher than this temperature, peanut bud will rot easily, and the most suitable temperature should be 25 degrees.
