In winter, the weather gradually cools, allowing the plants to die naturally in the field, allowing nutrients to flow back into the roots. Remove dried grass in the field. If the land has been frozen, it can be thawed with appropriate coverage. The soil between the rows was removed, and the bulb was pulled out of the ditch for cold stimulation and sunlight exposure to break the dormancy. After 3 to 5 days, the roots were discolored, soil fine fertilizer was applied, and the roots were irrigated. A root treatment and insecticide was used to treat the insects. Drench the water, set a wind barrier for every 2 inches, insert the bow bamboo strips, cover the membrane. Cover grass mulberry warming and heat preservation, keep it at 20 °C ~ 25 °C during the day. After the plant grows, it should be ventilated and ventilated to prevent humidity and prevent disease. On cloudy days, if the temperature in the bowl does not decrease, it is necessary to uncover the grasshopper and let the amaranth receive scattered light. The timely spraying of vegetables and strong stems promotes thick stems, thick leaves, fresh leaves, lush foliage, and strong natural taste. At the same time, it can increase the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons. Cover the first crop after covering 30-40 days. Immediately after harvest, ecological pesticides and new high-fat membranes were sprayed to prevent infection by pathogens. When the seedlings grow to 5~10 cm, apply urea once, pour water once, and then cover. The first time after the first day of collection can receive the second time, and the second time after the receipt of the third time can receive 30~35 days. After the weather gets warmer, remove the covering in time.
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.
