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

A nationally authorized protected variety - Longting Apricot-Plum
Longting Apricot-Plum is a new fruit tree variety discovered by forestry science and technology personnel in Longting Town, Xintai City, Shandong Province. It belongs to the Rosaceae family and is an accidental hybrid bud sport of apricot and plum. The State Forestry Administration has authorized protection, with authorization number 20030002. The Longting Apricot-Plum tree has grayish-white bark, many branches, the sunny side of the outer new shoots is red, elliptical leaves, white flowers, a high proportion of complete flowers, a flowering period of about 7 days, tolerance to low temperatures, resistance to late frost, and a high natural fruit-setting rate. The fruit is nearly spherical, with a smooth top, a shallow suture, and symmetrical sides. The average single fruit weight from natural fruit set is 47.5

What are the key points for choosing peach varieties for protected cultivation?
The correctness of variety selection is the key to successful protected cultivation. The purpose of protected cultivation of peach trees is to bring them to market early, so when selecting varieties, priority should be given to early-maturing and extremely early-maturing varieties with a short development period. A fruit development period of 60 to 70 days is appropriate, and no more than 80 days. Varieties should also have a short natural dormancy period and a low chilling requirement (cumulative chilling below 7.2°C of less than 850 hours), abundant pollen, a high self-fruitfulness rate, high yield, large fruit, good fruit quality, and tolerance for storage and transport. If they can

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

When is the covering time for protected cultivation of apricots?
For most apricot varieties, they must undergo a low-temperature period of 700-1000 hours below 7.2°C to break dormancy. Therefore, protected cultivation must raise the temperature only after the apricot's chilling requirement has been met, for success to be possible. If the temperature is raised too early, the apricot trees cannot sprout and bloom normally, and in severe cases it will cause a large number of flower buds to drop, uneven flowering, and severe flower and fruit drop. The timing of temperature increase should also be carefully decided based on the variety's chilling requirement and weather conditions. 1. Covering time for plastic greenhouses: Plastic greenhouses have poor insulation performance, so apricot trees must pass dormancy under natural conditions. The suitable covering time is generally from late January to early February, and the covering time is the temperature-raising time. If the weather is abnormal, such as a warm winter, the covering time should be appropriately delayed. For plastic greenhouses, ground film should be applied 15-20 days before covering to allow the soil temperature to rise slowly.
