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.

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

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.

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

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

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

What are the key points of Korean pine sowing and seedling-raising techniques?
The method for sowing and raising Korean pine seedlings is as follows: spring sowing is preferable. In Northeast China, mid-April to early June is better. Broadcasting or drilling in rows are both acceptable; in recent years, wide-row sowing is usually used, with a sowing width of 8 to 10 cm. After sowing, firm the soil once first, then cover with soil, with a soil cover thickness of about 2 cm. If timely irrigation is possible, the seedbed does not need to be covered with grass after sowing, and full-light seedling raising can be carried out. To eliminate weeds, after sowing and before seedling emergence, nitrofen at 3 grams per sq m, atrazine at 1 gram, or prometryn at 2 grams can be sprayed on the seedbed surface; do not irrigate within 10 hours after spraying. The sowing rate for Korean pine is 3000 to 37

Complete Analysis of Korean Pine Seed Collection Time and Methods
The time and methods for collecting Korean pine seeds are as follows: in natural Korean pine forests, the proportion of seed-bearing trees in 80-to-100-year-old stands accounts for over 91%. To solve the problem of insufficient Korean pine seeds, clonal seed orchards have been established, but they have not yet produced large quantities of seed. In natural forests, stands with good site conditions and vigorous growth are selected and designated as seed production stands, with intensified tending and management to prepare for seed collection. Korean pine cones mature from September to early October. When the cones turn from green to yellow-green and some seed scales begin to split, they enter the early ripening stage. After that, the seed scales gradually turn yellow, and individual cones begin to fall

Detailed Explanation of Key Techniques for Establishing a Seed Production Forest with Large Korean Pine Seedlings
Korean pine (Pinus koraiensis), of the family Pinaceae and genus Pinus, is an evergreen coniferous tree. It is mainly distributed in the Greater Khingan Mountains and Changbai Mountain areas of China, where its Korean pine forests form the climax community of the region, playing an enormous social, ecological and economic role. In the early years of the founding of New China, to meet the needs of economic construction, Korean pine timber was excessively logged, causing a massive decline in Korean pine trees; at present, only about 5 million mature Korean pine trees remain. Therefore, establishing Korean pine seed production forests on a large scale, rapidly and with high quality is of great
