Thirty-seven is a perennial herb, there is an annual growth cycle. Typically, more than two years in a growth cycle thirty-seven there are two peak growth in April-June and August-October peak of vegetative growth to reproductive peak. Thirty-seven germination temperature is 10-30 degrees, the optimum temperature is 20 degrees, the seed dormancy period of 45d-60d, seedlings need during hibernation after a period of time until germination cold treatment, and response to light very sensitive; conventional natural light 30% deemed necessary for proper growth and development, so thirty-seven shade of "three into the light, shade Qi Cheng" said; According to the latest research shows that the most appropriate thirty-seven shed light transmittance of 8 % -12%, more than 17% of the growth of Panax will be adversely affected. Thirty-seven from sowing to harvest, to go through three years of the time; annual notoginseng root seedlings usually do, from the second year onwards will be able to flowering and fruiting plants, usually in July budding, flowering in August, September firm, from October to November in batches ripe fruit. Cultivation techniques 1. Selection and preparation of land to black sandy loam soil generally anti-colonization with disabilities for the best. Soil pH pH4.5 ~ 7 is appropriate. Previous Crops of corn, beans, peanuts as well, do not use matriculation previous crop. Late August to land three times before planting, the first three centimeters deep tillage, the second 4-5 cm deep tillage, harrowing once. Third tillage depth 5 cm, the soil rake thin, then make high 25-30 cm wide and 100-110 cm furrow, Qimian made back-comb-shaped, two furrow between the gutter 45 to 60 cm, transplanting to and planting the same ground, and then capped Qimian corn stalks or weeds about 5 cm thick, burned to ashes, and then prepared for each hectare of manure composting: kang 52,500 kg of soil, manure 22,500 ~ 30,000 kg, cake 375 to 750 kg , total 75,000 kilograms, to be used when sowing and planting. Seeding and fertilizer when planting methods applied in three ways: (1) the fertilizer directly into the root soil or seed to do with the soil. (2) half of the fertilizer furrow soil incorporation, the other half used to make the casing. (3) cover a small plot of Middle-earth, holes and put manure on top. These three kinds of methods are required to achieve the overburden depth 2 cm.
