Practical Seedling raising technique of Schisandra chinensis

Seed treatment: in the first ten days of September, the plants with early fruit coloring, tight arrangement of fruit grains and large spikes were selected as seed trees, and the ripe berries in the middle and lower part of Schisandra chinensis were collected as seeds. After soaking in clean water for 3 days, rub off the pulp and bleach the shrunken seeds, remove the seeds and dry them in the shade in a ventilated place. Soak the seeds in early January, absorb water for 48 hours, remove the empty dry, mix the snow at the ratio of 1:3 and stir well, then store it in the shade outside. Calculate the sowing time, take out the seeds half a month before sowing, maintain a certain humidity to promote germination at room temperature, and about 60% of the seeds can be sown after about a week.

In early May, the treated seeds were sown on the prepared bed according to the row spacing of 5cm. Each hole was sown with 3 seeds, covered with fine soil 2 cm thick, and watered once with wood mulch. In order to prevent soil-borne diseases, 800-fold Dysenamine solution was sprayed combined with watering. Cover the bed with pine needles (Larix gmelinii). The thickness of the pine needles can not be seen from the top and can be seen from the side.

Weeds can be removed by 200 times Roundup on the seedling bed two weeks before emergence. When the emergence rate reaches more than 50%, a shading shed should be set up, and the sunshade net should be removed when the seedlings grow to more than 5 cm. After emergence, Gramineae weeds, such as root grass, barnyardgrass and atrazine, can be removed with selective herbicides. Urea 15 kg / mu and diamine 20 kg / mu were applied twice at seedling stage.
