Hydroponics can be used for 4-5 months, and its vitality is very tenacious. Water should be changed frequently during aquaculture to avoid turbid and smelly water and affect the healthy growth of hydroponics. Under proper hydroponic conditions, Liu Long can survive for half a year or even longer.
Liu Long usually refers to Salix matsudana, a deciduous tree with a height of 18m and a DBH of 80cm. Salix, Salix, broad and round crown, dark gray-black bark, longitudinal crack, upright or oblique branches, brown-yellow-green, brown after, hairless, hairy young branches, brown buds and slightly hairy.
Longliuxi is light-resistant, alkali-resistant, cold-resistant, water-resistant and moisture-resistant, and can grow in a dry place with high potential. The requirements for soil are not strict, but it is best to choose a plot with deep soil layer, loose soil, fertile soil and good irrigation and ventilation.
Correct method to improve soil Liu Long.
1, soil requirements
Liu Long has strong adaptability, but it is best to plant it in loose and fertile soil with good drainage to promote Liu Long to grow more vigorously. It is forbidden to use hardened and sticky soil, otherwise the root system in Liu Long will not grow vigorously, which will affect the later growth and development.
2. Fertilization management
Liu Long needs sufficient nutrients for its growth. During the cultivation period, decomposed manure can be applied to the soil as base fertilizer to improve soil fertility, and then Liu Long base fertilizer can be applied every year according to its growth before winter to provide sufficient nutrients for plant growth and development.
3. Scientific water use
In the process of breeding Liu Long, we should water it according to the growth of plants and the change of seasons. Generally, we need to water in time during the growing period to keep the soil slightly wet and avoid water accumulation. In addition, it should be watered once before winter to improve the cold resistance of Longliu, and drainage and flood control measures should be paid attention to in rainy season.
