Carbon sink patterns of old-growth Korean pine forests in Changbai Mountain revealed
On December 23, the project "Study on Carbon Sink Function of Old-Growth Broad-Leaved Korean Pine Forests in Changbai Mountain," completed under the auspices of the Jilin Changbai Mountain Forest Ecosystem National Field Scientific Observation and Research Station, passed expert review organized by the Changchun Branch of the Chinese Academy of Sciences in Changchun. Experts held that the integration of multiple methods in this project, along with research on flux changes of components and process mechanisms, has reached the international advanced level. As the main body of terrestrial ecosystems, forests' carbon cycle processes and mechanisms play an important role in understanding forest carbon sink functions and their impact on and response to global climate change, while old

Detailed Explanation of Key Techniques for Intercropping Pinellia ternata (Ban Xia) in Fruit Orchards
Encouraged by the national preferential policy of returning farmland to forest, the production area of fruit tree orchards in rural areas has increased noticeably over the past two to three years. At present, most orchards have grown into shady groves, and because of insufficient light between tree rows, intercropping conventional crops such as peanuts, soybeans, rapeseed, wheat, and corn results in poor growth, low yields, and poor returns. How to use the open spaces between orchard rows to increase intercropping returns is the issue of greatest concern to many farmers today. In practice, it has been found that intercropping the medicinal herb Pinellia ternata (Ban Xia) in fruit orchards can significantly increase economic income

How to solve the weeding problem in dry Pinellia ternata? An analysis of practical methods
Dry Pinellia ternata is a dicotyledonous plant. In the cultivation process of this medicinal material, the weeding problem is rather tricky, and there is currently no clear and effective method; it is still mainly manual weeding, and no herbicide weeding trials have been conducted. It is said that an expert specializing in Pinellia once used glufosinate after sowing dry Pinellia, with slight effect, but we do not know the specific dilution concentration. You might try using glufosinate starting from a low concentration (100-fold solution), testing in a small area with a gradient of ratios, and after observation, once it is confirmed that the herbicide has a clear killing effect on other weeds and

Key Field Management Techniques for Dry Pinellia (Ban Xia) Planted in Winter
After the Chinese medicinal herb dry Pinellia is planted in early winter, it enters the winter management stage. If overwintering management is poor, it will directly affect its yield and quality. Therefore, strengthening its winter management is very important. Based on production experience, growers should do the following four things during the overwintering period of dry Pinellia: Check the seed tubers. Normally, dry Pinellia tubers begin to take root and sprout about half a month after planting. Sometimes low temperatures cause tuber rot, so the growth of seed tubers should be checked in time. For spots where sprouts have still not emerged, use your hands or a bamboo strip or wooden stick to gently push the soil aside. Any seed tubers that have not rooted or whose rootlets are yellow-black are inferior seeds and should be dug out and replanted in time.

Dry Pinellia Greenhouse Planting Methods and Technical Key Points
Dry Pinellia, also known as three-leaf pinellia, three-step jump, and hemp jade fruit, is a commonly used Chinese medicinal herb, with wild distribution throughout both northern and southern China. In recent years, due to people's reclamation and utilization of barren hillsides and the extensive use of herbicides in farmland, its ecological environment has been damaged, resources have decreased year by year, and prices have continued to rise. According to surveys, dry Pinellia products are currently scarce in seventeen specialized medicinal herb markets nationwide, supply has fallen short of demand, and the market price has remained firm at 36-42 yuan/kg. Therefore, the market prospects for artificially cultivating dry Pinellia are very broad. In recent years, we

Detailed Explanation of Key Technical Points for Spring Planting of Pinellia ternata (Dry Pinellia)
In recent years, there has been a large supply-demand gap in the dry Pinellia market, and prices have been rising steadily, so production can be developed according to local conditions. Planting on slopes or intercropping with other crops: Pinellia ternata is a shade-tolerant crop, so gentle slopes can be chosen for planting, or it can be intercropped in young orchards and fields of tall crops such as corn and wheat. Pre-sowing sprouting promotion, mulching during the seedling stage; generally sown from February to April. Before sowing, the seed tubers are sprouted on indoor hotbeds, with the bed temperature maintained at 20°C, and sprouts can emerge after 15 days. Place the seed tubers in a plastic greenhouse with a temperature of 20-25°C for 15 days, and sow after the bud sheaths turn white.

A Detailed Guide to the Cultivation and Care of Five-Needle Pine Bonsai
The five-needle pine (Pinus parviflora) has lush branches and leaves, vigorous and emerald green, with gnarled branches and needle-like foliage, twisting and curling, appearing elegant and antique; it is a precious bonsai tree. Every year in midsummer, the high heat, intense sunlight and frequent rainfall are most unfavorable to the growth of five-needle pine bonsai, and care and management at this time are very important. Moderate light: the five-needle pine is a neutral plant and can grow in sunny or relatively shaded places, but when cared for in a sunny, well-ventilated place, the needles grow emerald green and robust; in places with insufficient light and hot conditions, the needles grow thin and weak and tend to turn yellow. It is best to give the five-needle pine daily

A Detailed Guide to the Making and Management of Pine and Cypress Bonsai
Based on the characteristics of the cultural landscape and combined with the thick and dwarfed features of Shandong mountain pines and cypresses, the old trunks and thick branches are thinned and pruned to lower the trunk and reduce the crown; then the method of coarse wiring and fine trimming is adopted, guiding the tree according to its natural tendency, so that the crown follows its natural form and the layers interlock and alternate. Within each large layer there are also small variations, giving both a sense of overall unity and an uncluttered appearance, preserving the wonder of natural formation; and by making full use of dwarfed wild stump resources, black pine stumps are used with grafting methods such as *grafting, high-branch side grafting, and bud grafting to change the crown into five-needle pine. Making use of the abundant Chinese arborvitae
