The plant morphological height of Pseudostellaria heterophylla is 1020cm. The root tuber is spindle-shaped, fleshy, surrounded by sparse fibrous roots, and the outer skin is yellow and white. The lower part of the stem is purple, nearly square, the leaves are opposite, and the leaf margin is microwave-like. The lower leaves in the middle of the stem are inverted, and the leaves near the ground are the smallest. Leaves above the middle of the stem are ovate-lanceolate to oblong. The flowers at the lower part of the stem are smaller, with 4 sepals, closed and without petals; The flower at the stem end is large, with 5 sepals, spreading, 5 petals, and white. Capsule ovoid. The seeds are spherical, dark brown, and have warty protrusions. The flowering period is from mid-March to early May and the fruiting period is from early April to early June.
The cultivation of Pseudostellaria heterophylla should have a mild and humid climate, like fertilizer, be afraid of waterlogging, be afraid of high temperature and strong light irradiation, have strong cold tolerance and grow well in loose sandy loam rich in humus. The distribution of root system is shallow. It has the characteristics of low temperature germination, rooting and overwintering.
The whole growth period is about 120 days.
Mainly propagated with tuberous roots. It is advisable to choose hilly slopes or flat land with higher terrain in the north and east. Sweet potatoes and vegetables are the best previous crops. Generally, after the early autumn crops are harvested, the land is plowed, sufficient base fertilizer is applied, and then plowed and raked for border tillage. Cold dew can be planted on the ground to freeze, but it is better before the first frost. If it is too late, the seed ginseng will begin to germinate, which will easily hurt the bud head and affect the emergence of seedlings. Before planting, the seed ginseng is dug out in the reserved field, and the root tuber with complete bud head, large and tidy ginseng body, no damage and no pests and diseases is selected as the seed. Planting methods are:
① Flat planting method. Open a straight trench on the boundary with a depth of 7 10cm. Sprinkle the base fertilizer into the ditch, cover with some fine soil, and horizontally discharge the seed ginseng into the ditch with a spacing of 56cm. Ginseng seeds are connected end to end, and then a ditch with row spacing of 10 15cm is opened, and the ditch is covered with soil before sowing. Finally, the surface of the frame is set to the shape of arch back.
② Vertical planting method. The depth of the ditch is deeper than that of the flat planting method, about 14cm. When planting, arrange the seed ginseng vertically in the ditch, head up, tail down, bud head off the ground about 7 cm, and then cover the soil. The seed dosage per hectare is 6001050kg. After emergence, soil cultivation should be combined with ditching and soil preparation. The thickness should be less than 2 cm, and the furrow should not be too deep. The furrow must be clear to facilitate drainage. Pay attention to watering in dry season. Pests and diseases include virus disease, leaf spot disease and root rot; Grubs, ground tigers and moles.
