Cultivation techniques of Astragalus membranaceus: Multi-purpose cutting propagation can be carried out at 20 °C. After cutting the seedlings to grow roots, the soft branches of the yellow scorpion on the basin, 3 pots per pot, timely picking the heart, culture dwarf and full plant shape. Hardwood scutellaria, when planted in small seedlings, can be planted first, picking the heart in time, cultivating the branches, branching 5-6 branches, then moving the basin; pruning and shaping, cultivating dwarf plant shape. During the growing season, the soil is often kept moist, and fertilized once every 20 days to promote the vigorous growth of the branches and flowers. Control the moisture during the dormant period.
Some plants have not fallen after the yellow leaves, so the normal photosynthesis, transpiration and respiration of plants will be affected. Therefore, the leaves and leaves of the yellow leaves should be cut off, so that the remaining leaves will be better absorbed. Nutrition is also beneficial for plants to re-emerge and avoid disease infection. In addition, after plant frostbite, it is generally not necessary to apply fertilizer, watering should also be moderate, to control the water, because the plants in the recovery period are difficult to absorb nutrients, watering more, plants can not absorb, but will cause its roots to rot.
Potted with peat soil or humus soil, liquid fertilizer is applied once every 1-2 weeks in the growing season. Hi warm, the minimum temperature in winter should be above 15 °C; strong positive plants, can be transplanted in the summer under the sun, and there is direct sunlight in the winter. Hi wet environment. In the spring to autumn, the potting soil is kept full of water, and the watering is appropriately reduced in the winter to keep the basin soil slightly tidal.
