First of all, in Liangtuliang, from early April to mid-autumn, the soil around the stems of the trunk was turned outwards to expose the base of the roots to reduce the soil moisture around the trunks and prevent the damage of the rhizomes like weevil and aromatous moth. Secondly, disc fertilization, if the winter has not had time to put fertilization, the spring continues. Before the walnuts germinate, combine the tree trays, apply 5 to 15 pounds of ammonium bicarbonate per plant, apply fertilization in the applicator or ring groove. Finally, watering, from late March to early April, before the sprouting of the walnuts, if the rain is not enough when the weather is dry, we must pour water once to promote the rapid growth of new shoots. Newly planted walnuts should pay attention to watering and improve the survival rate of young trees.
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.
