Generally, before sowing and planting, 50% carbendazim wettable powder is applied to the ginseng bed surface at the ratio of 0/5 ~ 20g per square meter/kloc-0, and then mixed into the soil several centimeters above the bed surface, and the effect is good. Luheng 1, a new pesticide produced by a company in recent years, is a new type of high efficiency and low toxicity broad-spectrum systemic soil fungicide, which is mainly effective against rice sheath blight and other seedling diseases. In particular, it has a strong killing effect on Fusarium, seedling rot, pythium and Rhizoctonia. The cooperative experiment between Jilin Agricultural University and Fusong Ginseng Research Institute proved that the control effect reached 90.7% by applying 1g per square meter in the soil before planting ginseng. Before the emergence of ginseng, the soil was irrigated with 2000 times solution of Luheng 1 to make it penetrate into 2 ~ 3cm soil layer, and the control effect of ginseng damping-off reached 94.2%. The experiment of Ginseng Research Institute in Ji 'an City, Jilin Province has also received good results, and it is a new pesticide worth popularizing. 76. How to sow and raise seedlings of wild ginseng?

In order to cultivate strong seedlings, we should use on-demand sowing, also known as hole sowing, and the row spacing varies according to the age of transplanted seedlings. For a two-year transplanter, the row spacing can be 4cm× 4cm. Because the transplantation of striped sea cucumber needs plastic surgery, the plastic surgery effect of two-year-old seedlings is poor, so most of them are three-year-old seedlings, so the row spacing is 5 cm× 5 cm. 27.5-30g of water seeds are used in the plant spacing of 4 cm× 4 cm, and 20g of water seeds are used in the plant spacing of 5 cm× 5 cm (0.5kg of dry seeds becomes 0.6kg after germination, and 0.5kg of water seeds becomes 0.45kg after germination). After sowing, cover the soil for 3 ~ 4cm, smooth the border, and then cover it tightly with roots or grass, with a thickness of 5 ~ 6cm. Cover the shady slope plot and the bed side tightly, but the straw cover should not be too thick, otherwise the ground temperature is low, which is not conducive to the development of seeds and embryos. Digging drains combined with covering the bed surface can not only keep the bed soil moist, but also prevent the bed soil from being too wet, and also prevent slow freezing and Sclerotinia sclerotiorum.

The advantages of sowing on demand are that the seeds are evenly distributed in the border bed, the nutrient areas of the participating plants are consistent, the ventilation and light transmission are good, and the plants grow healthily, but the disadvantages are labor-consuming. If the labor force is insufficient or the time is needed to sow in time, the sowing method can also be used. The specific operation is to rake the soil in the border bed onto the working path, spread the seeds evenly on the border bed, and then cover the soil with the same thickness as that sown on demand.
