After the garlic has entered the middle growth period, the garlic has gradually expanded, and it is necessary to focus on the following management tasks:
In the middle and late periods of the growth of garlic in Qingcun Lizao, there is an increase in rainwater. In some ditch-unmatched lands, waterlogging disasters are very likely to occur and affect the growth of garlic. Therefore, we must do a good job in clearing and digging the garlic field to ensure that the "three ditch" supporting, so that the drought can irrigation, energy can be discharged, the rain to stop the stem, to prevent the occurrence of rain and waterlogging.
After the water management enters the spring, the temperature rises, and the windy weather increases. The demand of garlic for water increases. Local governments must pay attention to the water management of garlic, and once a day, garlic is swollen with water.
Supplementary fertilizers The critical period for garlic to absorb fertilizers is the growth of garlic sprouts until the expansion of garlic bulbs. Should be based on the growth of garlic, take the appropriate measures to supplement fertilizer: First, combined irrigation and fertilization, urea 15-20 kg per mu; Second, spray 0.5% urea solution, 0.3% potassium dihydrogen phosphate solution or other organic foliage Fertilizer; The third is to spray garlic in the early stage of garlic expansion, swelling, with 200 ml per mu water 40-50 kg spray.
Ventilation is one of the most important components in a successful greenhouse.
If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
