What are the latest key points to note when growing garlic sprouts in greenhouses?
Garlic sprouts are a very important seasoning and side vegetable in our daily lives. The daily consumption of garlic sprouts is very large, and although the market price is not high, there is a relatively high market demand. Therefore, the planting area of garlic sprouts in our country is currently very extensive. And garlic sprouts are mostly grown in greenhouses. So what do we need to pay attention to when growing garlic sprouts in greenhouses? Let's take a look together below!
1. Sowing management
The planting method for growing garlic sprouts in greenhouses is generally mainly furrow sowing, and we need to control the row and plant spacing well and dig the sowing furrows properly. When planting, sow the garlic seeds evenly into the sowing furrows. While sowing, cover with soil at the same time to ensure the garlic seeds stand upright and avoid affecting garlic seed germination. After sowing, water promptly, and after watering cover with a layer of fine soil to improve the soil's moisture conservation capacity. Then water about once every two times, with appropriate fertilization. When the seedlings grow to about 22cm, cover with another layer of soil, and after the seedlings emerge, do a good job of pest and disease prevention and control.
2. Water management
Water is very important for the growth of garlic sprouts, and garlic sprouts have a certain demand for water throughout their entire growth period. We should reasonably adjust the amount and frequency of watering according to the soil moisture, weather and the growth condition of the garlic sprouts. And we should also appropriately sprinkle-irrigate with a new high-fat film at about 18 degrees to improve the disease resistance of the garlic sprouts. After the garlic sprouts are sown and before they enter the growth period, irrigate once with a large amount of water. After entering the growth period, pay attention to the watering intensity, and about 5 days before harvest, drip-irrigate once with a small amount of water.
3. Temperature and light
Temperature and light also have a certain impact on the growth of garlic sprouts. Garlic sprouts have a relatively large demand for light during growth, so when growing them in greenhouses we should pay attention to keeping the greenhouse film sufficiently transparent, regularly clean the greenhouse film, and increase light intensity. Then we can appropriately spray nutrient film fertilizer to improve the utilization rate of light. During the day, the temperature should be maintained at about 20 degrees, and at night it should also be controlled at about 15 degrees, maintaining a certain day-night temperature difference. A suitable growing environment is very helpful for the growth of garlic sprouts.
4. Pest and disease control
Finally, of course, there is the work of pest and disease control, as pests and diseases are very harmful to garlic sprouts. If not taken seriously, in mild cases it will lead to a serious decline in garlic sprout yield, and in severe cases it will lead to the death of garlic sprouts and a total loss. So during the planting process we must pay attention to strengthening management, controlling temperature and humidity well, and not giving pests and diseases the conditions to develop. Then we should regularly do a good job of disinfection to reduce the pathogen base in the greenhouse. Then after disease occurs, inspect promptly and take corresponding countermeasures.
The above is a brief introduction to the key points to note when growing garlic sprouts in greenhouses. During the planting process, we must do a good job in all aspects of management to prevent unnecessary losses. That is all for today's introduction. This article is for reference only.
