Planting Schizonepeta tenuifolia generally applies farm fertilizer. When applying base fertilizer, it is necessary to first apply the rotten human and livestock manure water to the land, then deeply plough for 7-10CM, and then integrate the land. Fertilizer should be applied 2-3 times at the rapid growth stage of seedlings. For the first time, a large amount of rotten human and animal manure should be applied to promote the rooting of plants. Compost again at an interval of about half a month. In the later stage, whether to apply fertilizer or not can be determined according to their growth status. 1、 What fertilizer should be applied to Schizonepeta tenuifolia 1 Base fertilizer: Schizonepeta tenuifolia is generally applied with farm fertilizer. Before planting, apply 2000-3000 kg of farm fertilizer per mu. These fertilizers can effectively improve soil structure and provide a large number of trace elements for plant growth.
2. Topdressing: Schizonepeta tenuifolia has a high demand for fertilizer. It is necessary to apply fertilizer in time to supplement the nutrients required for rhizome growth. When the seedling grows to about 20cm, apply farm fertilizer once, and it is recommended to control it at about 1500-2500 kg per mu. When the seedlings grow to about 30cm, they should be composted again. Generally, human and animal manure, plant ash and cake fertilizer are fully mixed and fermented, and then ditches are opened near the plants for fertilization, covered with soil and compacted. 2、 Planting time of Schizonepeta tenuifolia 1 Spring sowing: the growth time of spring sowing is generally about 150 days. It can be planted around the Qingming Festival and harvested before and after the autumn equinox. The characteristic of spring sowing is that the rhizome of Schizonepeta tenuifolia grows well, but the ear yield is not high.
2. Summer sowing: the growth time of summer sowing is generally about 120 days. Sow between grain in ear and summer solstice, and harvest after cold dew. Summer sowing is characterized by short Rhizome Growth, but good ear grain growth and high ear yield.
3. Whether to sow in spring or summer can be selected according to the planting purpose. For the purpose of high ear yield, summer sowing can be selected. If you want to improve the quality of rhizomes, spring sowing can be selected. （JingGaiShiShenMeFei）
