Answer: Tubal saplings, especially new saplings, are vulnerable to walnut giardia, resulting in debilitating or dead saplings. Tu white is the main measure to control the spawning hazards of walnut giardia. Lime 6 kg, salt 1 ~ 1.25 kg, bean surface 0.25 kg, water 18 kg, will be calcined open, add salt and bean flour, stir evenly, apply to small saplings and trees 1.2 meters below the main trunk. At the same time, weeding ash. After the walnut tree sprouts, there is often a small black beetle that harms the walnut bud. As long as a handful of plant ash is sprinkled on the shoots of each young tree and around the trunk, the pests can be killed and the young shoots can be protected from harm.
Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
