Embodiment 1

[0060] Embodiment 1: a method for sexual reproduction of heterophylla, comprising the following steps:

[0061] (1) Selection of individual plants: In early May 2010, field observation and selection were carried out at the Pseudostellaria heterophylla planting base in Dachang Town, Shibingniu, Guizhou Sanyuan Taibao Industrial Co., Ltd. The selected plants were 20-25 cm high; the stems were upright, and the branches were 5~ 8, slightly purple; opposite leaves, dark green, broadly ovate, 8-10 cm long, 3-5 cm wide, with 2 pairs of large leaves at the top, forming a cross shape, no pests or diseases; capsule Wide ovoid, good single plant with 10-18 seeds of normal fruit and 7-15 seeds of atretic fruit, and mark it well;

[0062] (2) Harvesting fruit: manual harvesting is adopted, and the fruit is picked as it matures in the middle and late May. The sign of fruit maturity is that the capsule peel is slightly cracked. Fruits with more than 15 seeds and more than 12 mature seeds of...

Abstract

The invention discloses a method of sexual reproduction of radix psuedostellariae, which comprises the following steps that (1) a single plant is selected; (2) fruits are collected; (3) seeds are manually treated; (4) dormancy of the seeds is released; (5) land is prepared; (6) the seeds are sown, wherein the seeds are covered by fine soil, the thickness of the covered soil is 0 to 8 cm, and the soil on the box side is compacted; (7) field management is performed; and (8) the seeds are timely collected. According to the method, firstly, the good single plant and the seeds of the radix psuedostellariae are selected, so that the viability of the seeds reaches more than 94.49%, and the moisture content and the storage temperature and humidity of the seeds are controlled, so that the germination rate of the seeds of the radix psuedostellariae reaches more than 89.17%. In addition, the reasonable thickness of the covering soil is determined, so that the emergence rate of the radix pseudostellariae plant reaches 63.58%, the root dry weight per square meter reaches more than 198.83 g, and the reasonable collecting time is controlled, so that the quality and the yield of the medicine are guaranteed.

Description

technical field [0001] The invention relates to a method for sexual reproduction of heterophylla, belonging to the field of plant cultivation. Background technique [0002] Pseudostellaria heterophylla (Miq. ) Pax ex Pax et Hoffm. is the dried root of Pseudostellaria heterophylla (Miq. ) Pax ex Pax et Hoffm., which has the effects of nourishing qi and invigorating the spleen, promoting body fluid and moisturizing the lungs. Modern pharmacological studies have found that Pseudostellariae Pseudostellariae has various effects such as improving chronic heart failure, improving memory, lowering blood sugar, and antioxidant activity. In recent years, as the market demand for Pseudostellaria Radix Pseudostellariae has increased day by day, the price has continued to rise, and the cultivation scale has also continued to expand. [0003] For a long time, Radix Pseudostellariae has been cultivated by root tubers for vegetative propagation, which is not only costly, but also degrades ...
