Seedling raising techniques of Lycium barbarum

Chinese wolfberry LyciumchinensisMill.

Dubious name: invading Wah Yin-Hari Mog

Alias: Chinese wolfberry, dog milk

Family and genus: Lycium barbarum of Solanaceae

Morphological features: shrubs, more than 1 meter high, much branched, slender and weak branches, often curved and drooping, with spines, light gray, with longitudinal stripes. Leaves alternate or clustered in lower parts of branches, narrowly rhombic-ovate to ovate-lanceolate, ovate, long-elliptic, 1.5 ~ 3.5 (6) cm long, 5 ~ 10 (22) mm wide, apex acute, base cuneate, entire, both surfaces glabrous. Flowers often 1 mur2 (5) fascicled in leaf axils, pedicels fine; calyx campanulate, apex 3 murine 5-lobed, lobes more or less ciliate; Corolla funnelform, purple, apex 5-lobed, lobes spreading outward, as long as tube or slightly longer, margin densely ciliate, basal auricles conspicuous; stamen filaments different in length. Berries ovate or rectangular round, crimson or orange-red. The florescence is from July to August and the fruiting period is from August to October.

Habitat: born in thickets of roadsides, cottages, ridges and hills.

Distribution: cultivated in Chifeng City, Xingan. It is widely distributed in all provinces and regions of the country, as well as in eastern Asia and Europe.

Ecological habits: mesophytes. Most of them are born in arid sandy land and saline-alkali land. Multi-introduction and cultivation in various parts of the three northern regions.

Methods of reproduction:

Seeds reproduce. Chinese wolfberry is easy to collect seeds and has a large number of seeds, so it is generally propagated by seeds. However, because the seeds are small, the ability of topping soil is poor, and the seedlings are very weak, the key techniques should be mastered when raising seedlings.

1. Methods of raising seedlings.

1.1 choose a place. Chinese wolfberry seedlings should choose places with flat terrain, fertile soil, adequate water supply and good drainage.

1.2 make a bed by preparing the ground. Soil preparation should be carried out in the autumn of the previous year, deep ploughing 20~25cm, and raking flat in time. The base fertilizer was applied in the spring of the second year. Make bed: the width of the bed is 1.0m and the length is 5m. It can also be determined according to the situation.

1.3 Irrigation with bottom water. The bottom water was fully irrigated 5-7 days before sowing, and the irrigation was checked on the second day. If there is still dry soil on the bed, it should be irrigated immediately until it is thoroughly filled.

1.4 sow seeds. Mix sand, pull ditch 1~1.5cm, cover soil around 0.5cm, cover with film to increase ground temperature and maintain humidity. Wait for the seedlings to grow out, pay attention to shade, to prevent exposure to death. After the stems and leaves of the seedlings turn green, remove the grass curtain.

1.5 Seedling management. It is roughly divided into four stages. The first stage is the seedling emergence stage: from May 15 to May 25, that is, from sowing to the whole seedling for about 10 days. in this stage, the seedlings are mainly rooted, arched soil and emergence, and the main management measures are to control diseases and insect pests, spray water on the bed and keep the bed moist in order to preserve the seedlings. The second stage is the squatting seedling stage. From late May to late June, that is, the seedlings began to grow four leaves, and the height of the above-ground seedlings grew slowly, while the root system grew fast. the focus of this period of management was insect control, weeding, loosening soil, seedling and irrigation, and spraying water to cool down in case of high temperature weather to ensure the normal growth of seedlings. The third stage is the seedling growth period, from early July to mid-August, during which seedlings grow rapidly, mainly in pest control, topdressing, irrigation, weeding and topping. The fourth stage is from late August to mid-September, in the later stage of growth, to promote the Lignification of seedlings as soon as possible, mainly loosening the soil and pulling weeds.

two。 Problems that should be paid attention to.

2.1 do not be too dense when raising seedlings. Sowing leaves seedlings too dense, seedling growth is weak, root system development is not strong, resistance is not strong, planting is not easy to survive, or seriously withered shoots.

2.2 pinching in time. Pinching was carried out in the middle of August to promote the Lignification of seedlings, so that the survival rate was high and the growth was good after planting.

2.3 weeding in time. Because Lycium barbarum likes light, there are too many weeds, which affect photosynthesis and make the seedlings die.

Economic value and use: medicinal fruit and root bark, the efficacy is the same as that of Ningxia wolfberry.
