Key cultivation techniques for Angelica sinensis seedling transplanting and direct seeding propagation
1. Seedling transplanting (1) Seed selection: Fresh seeds set in the second year after transplanting should be selected as seed. Around the Start of Autumn, when the seed coat turns sky blue or pink and the flowering stems droop, cut them off together with the flowering stems, place them in a ventilated and dry place to dry, then thresh and store for later use. Never expose to strong sun, roast, or rain. (2) Sowing and seedling raising: Generally sow around the Start of Autumn, sowing immediately after harvest; in lower-altitude areas with slightly higher temperatures, sowing from mid-August to early September is suitable. Timely sowing can avoid early bolting of Angelica sinensis. If too early, the seedling growth period is long,

Key Points of High-Yield Cultivation Techniques for Direct-Seeded Soybean after Wheat Harvest
The Longkou City Agricultural Technology Promotion Center conducted a two-year study on summer direct-seeded soybean after wheat harvest. The experiment used the Ludou 11 variety, and the yield per 667 sq m reached more than 300 kg. Through the experiment, the wheat-soybean direct seeding method replaced the wheat-corn relay intercropping model, with a significant increase in benefits, raising income by more than 400 yuan per 667 sq m. The key techniques are early seeding by rushing the stubble, single-seed sowing, density control, and timely harvest. 1. Variety selection and treatment. Select varieties with stiff stems that do not lodge

Direct seeding cultivation techniques for licorice in the Hexi arid region
Licorice is the most commonly used bulk medicinal herb, hailed as the king of medicines. The currently cultivated species is Glycyrrhiza uralensis (Ural licorice), a plant of the genus Glycyrrhiza in the Fabaceae family. It is highly water-saving, drought-tolerant and cold-tolerant, and is an excellent windbreak and sand-fixing vegetation for arid and semi-arid desert areas. The medicinal part is the dried root, which not only has effects such as tonifying the spleen and boosting qi, relieving cough and expelling phlegm, clearing heat and detoxifying, and harmonizing the properties of medicines, but is also widely used in daily necessities, light industry, animal husbandry and the food industry. Minqin County, located on the edge of the Badain Jaran Desert and the Tengger Desert, is a major production area for cultivated licorice in Gansu Province

Detailed Explanation of Direct Seeding Cultivation Techniques for Licorice
Cultivation Techniques Site Selection Licorice is a deep-rooted plant, so flat, fertile, loose sandy soil or loam should be selected for planting. The best preceding crops are wheat, corn, and melon or vegetable fields, and continuous cropping with sugar beet or sunflower should be avoided. Land Preparation and Fertilization Deep plow the selected land to more than 26 cm, apply 2000 kg to 3000 kg of fully decomposed organic fertilizer per mu, and 18 kg to 20 kg of diammonium phosphate, then harrow the soil finely, level it, and make beds. The bed ridges should be 20 cm to 30 cm wide and 20 cm high, the beds should be 2 m to 2.5 m wide, and the bed length depends on the terrain.

How to grow direct-seeded rice? Experience shared by Jingtoushan Farm
Our farm has nearly 700 hectares of paddy fields. We began direct seeding of rice in 1987 and fully promoted it starting in 1999, with a 100% success rate. The key points of this direct seeding technique are mastering the following three critical stages. 1. Land preparation stage. Plow the paddy field, break up the soil, and irrigate; either machine leveling or oxen leveling will do. Then use a leveling bar to smooth the field flat. Use a homemade ditching board to open the furrows. The ditching board is 2 m long, 45 cm wide, and 3 cm thick. On the wooden board, nail 2 handles on each side, each 30 cm long, with a width of 1.6 m between the handles, for attaching ox harness ropes

Detailed Explanation of Key Techniques for Direct Seeding Afforestation of Siberian Apricot
Direct seeding afforestation of Siberian apricot requires little investment, forms forests quickly, has low costs, is simple and easy to carry out, and moreover delivers very considerable benefits. Its development prospects are extremely broad, and it is one of the important ways for people in mountainous areas to build wealth. 1. Time and method of direct seeding Direct seeding afforestation of Siberian apricot is divided into two types: spring sowing and autumn sowing. ① Autumn sowing: for autumn-sown seeds, soak the seeds in 50-60°C water for 24-48 hours, remove them and rinse repeatedly with clean water, then dress the seeds with 10% zinc phosphide or another repellent (to prevent rodent damage), and then sow. ② Spring sowing: for spring-sown seeds, after the beginning of winter,

Key Technical Points and Methods for Direct Seeding Afforestation of Caragana microphylla
Caragana microphylla, a shrub or small tree of the Fabaceae (Papilionaceae) family, is extremely light-demanding, resistant to severe cold and intense heat, highly tolerant of drought and barren soil, and highly adaptable. It is an excellent tree species for sand fixation and soil conservation in deserts and grasslands. Its tender branches and fresh leaves are good fodder for livestock, especially sheep, and it is also a good firewood plantation species. Seeds can be collected for direct seeding afforestation. The seeds mature from July to August; harvest when the pods are hard and yellow-brown. The time from fruit maturity to pod dehiscence is very short, so harvest as they ripen. Dry the harvested pods in the sun and remove the pod shells and debris. Good seeds are yellow-green or cream-yellow and glossy.

Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing
Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control

Do not use cottonseed hulls with a high content of cottonseed kernels directly for cultivating oyster mushrooms
Cottonseed hulls consist of the hulls left after the kernels are removed from cottonseed, the short cotton lint attached to the hulls, and a small amount of broken cottonseed kernels. Cottonseed hulls are rich in nitrogen, phosphorus, potassium, cellulose and lignin, with a carbon-to-nitrogen ratio of 79-85:1, are slightly alkaline, loose outside and dense inside, have good air permeability and strong water retention, and are a top-grade material for edible mushroom cultivation. However, cottonseed hulls contain toxic substances, and after sterilization under high pressure or normal pressure they release aldehydes, ketones and acids, and these toxic substances inhibit mycelial growth, delay pinning, and cause undesirable outcomes such as small mushrooms and poor mushroom quality.

High-yield cultivation techniques for no-till direct seeding in rapeseed-rice double cropping
Zhejiang Province is relatively economically developed, with high labor costs. At the same time, as diesel prices rise, the cost of mechanical plowing of farmland increases, and the production cost of grain and oil crops increases year by year. For this reason, Zhejiang Province carried out trials, demonstrations and extension of high-yield cultivation techniques for no-till direct seeding in rapeseed-rice double cropping, which reduced the production cost of grain and oil crops and improved planting efficiency. According to surveys, each mu of no-till direct-seeded rapeseed saves 62.5 yuan in costs and increases efficiency compared with transplanted rapeseed, and each mu of no-till direct-seeded late rice saves 70.24 yuan in costs and increases efficiency compared with plowed and transplanted late rice. The annual cumulative cost saving and efficiency increase of no-till direct seeding cultivation in rapeseed-rice double cropping is 132.74 yuan.
