A new method of raising seedlings of Schisandra chinensis

Schisandra chinensis is a perennial vine of Magnoliaceae, which is used in medicine with ripe and dry fruit, commonly known as Schisandra chinensis, which has the effects of invigorating the lung and relieving cough, tonifying kidney and astringent essence, replenishing qi and promoting fluid. There are Schisandra chinensis and Schisandra chinensis in the same genus, and Schisandra chinensis is the best in its efficacy and commercial value. Judging from the current market situation, the prospect of developing Schisandra chinensis is very broad.

A new method of raising seedlings of Schisandra chinensis by using open space is introduced in this paper. The experiment was conducted in Tumen Village, Yongquan Village, Jiucaigou Township, Xiuyan County. The tested area is 1 mu, the soil is sandy loam, and the condition of drainage and irrigation is good. The trial time was from 2002 to 2004.

1. In the middle of October 2002, 740 one-year-old Schisandra chinensis were planted in the experimental garden according to row spacing of 3 meters and plant spacing of 0.3 meters. At the same time, a border bed of 120cm wide and 20cm high was made between the rows, and 4000 kg of rotten barnyard manure was applied as base fertilizer per mu for fine soil preparation.

two。 Sow and harvest ripe fruit (wild or cultivated), wash the pulp and dry it. Before freezing in 2002, a deep 3 cm ditch was opened on the seedling bed according to the row spacing of 25 cm, flat, evenly sowed, and the soil was 2 cm thick, then covered the bed with straw and watered thoroughly. The sowing rate is 5 kilograms per mu.

3. In the second year of field management, the plant was set up in time (cement column and line 8) before turning green, and the vine was put on the shelf after turning green, and the plant was pruned properly during the growth period. The mulch was gradually removed when the emergence rate of Schisandra chinensis in inter-row seedlings reached 70%. When the seedling height is 5 cm, the seedling is set according to the plant spacing of 3 cm, leaving 20000 seedlings per mu, watering in time in case of drought, combined with weeding and loosening the soil properly, so as not to hurt the root system.

The advantage of this method is the combination of height and height of the same variety, three-dimensional cultivation, planting and seedling raising, which not only creates a good ventilated and transparent environment for adult Schisandra chinensis, but also provides certain shading and shading conditions for seedlings bred between rows. At the same time, it makes full use of the effective area of cultivated land. The economic benefit of this method is 5-10 times higher than that of simple Schisandra chinensis seedlings and planting other crops between rows. According to the market situation of that year, the income per mu is nearly 10,000 yuan. In the autumn of 2003, we repeated the experiment of the previous year and achieved the same effect. The experimental results show that the method of cultivating Schisandra chinensis seedlings has many advantages, is feasible and worth popularizing.
