Detailed Cultivation Techniques for Leafy Goji in Protected Culture
Leafy goji, also known as goji shoots, goji berries, goutdiya, digupi, etc., is grown for its tender stems (young shoots), which can be eaten cold-tossed or stir-fried, and can also be used in soups or as a hot pot ingredient. The key cultivation techniques are as follows: 1. Cutting propagation: Because leafy goji is continuously harvested for its young shoots, it generally does not flower or set seed, so cutting propagation is mostly used. ① Cutting time: Take cuttings for seedling production in open ground or protected culture in August-September. ② Selection and treatment of cuttings: Select disease-free, robustly growing plants, take branches that are 1 year old, 0.5-0.8 cm in diameter,

Key Technical Points for Protected Cultivation of Leafy Goji (Vegetable Goji)
Every 100 grams of tender stems and leaves of goji contains 5.8 grams of protein, 1.0 grams of fat, 6.0 grams of sugar, 3.96 milligrams of carotene, 0.23 grams of thiamine, 1.1 milligrams of nicotinic acid, and 3.0 milligrams of vitamin C. Regular consumption has health benefits such as improving eyesight, nourishing yin and moistening the lungs, enhancing immune function, and anti-aging. Consumers in southern China are accustomed to using goji tender stems and leaves in soups or stir-fries, and there is considerable demand in some cities; Guangzhou alone has an annual output of about 70,000 tons. Introducing vegetable goji for protected cultivation in the north can both enrich the variety of vegetables

How can Gastrodia elata in the Changbai Mountains of Jilin be protected from frost damage in years with little snow?
Wild Gastrodia elata in the Changbai Mountains of Jilin is mostly distributed in high-mountain broad-leaved mixed forests at an altitude of 500-2500 m with cool and humid summers, deep winter snow cover, high ground coverage, a thick layer of fallen branches and leaves, a relatively shallow frozen layer, and loose soil. Wild Gastrodia elata suffers frost damage in winters with little snowfall and a thick frozen layer, and cultivated Gastrodia elata also suffers frost damage when cold-protection measures are inadequate. In both 1981 and 1982, heavy snow sealed the ground, with winter snow 80 cm thick; when the snow was broken open, the frozen layer on the ground was found to be only 3 cm, so neither wild nor cultivated

Detailed Explanation of the Seedling Raising Method for Schisandra chinensis Under Protected Cultivation
In places with a short frost-free period, direct sowing and seedling raising in the open field generally requires two years before the seedlings can leave the nursery. If the method of raising seedlings in nutrient pots under protected cultivation and then transplanting them into an open-field nursery is adopted, the goal of raising seedlings and having them leave the nursery in the same year can be achieved. In early April, set up a plastic greenhouse or a medium-sized arched shed similar to those used for rice seedling raising. Before sowing, water the nutrient soil in the paper cups thoroughly. When sowing, mix Dimiaoling into the bottom soil and the covering soil. After sowing, together with watering, spray 800-1000 times diluted Amobam. Sow 2-3 seeds per paper cup, cover with soil 2 cm thick, and maintain humidity after sowing. Generally
