Intercropping soybeans with yew can increase the survival rate
Recently, 2.46 million rooted cuttings of Maire yew (Taxus media) cultivated at a yew nursery in Youxian County, Zhuzhou, Hunan, have been growing rapidly in Tongshan Village, Yajiangqiao Town in that county, and passed expert inspection at the end of August. The nursery's new seedling-raising method of "intercropping with soybeans" has raised the survival rate of yew seedlings to more than 95%. It is reported that the successful introduction and propagation of Maire yew not only helps protect the precious wild Chinese yew (Taxus wallichiana var. mairei) resources, but also opens up broad prospects for developing this "golden plant." At present, the nursery is engaged in forestry

How to prevent spider plant leaf tips from withering? Three methods to teach you
Spider plant (Chlorophytum comosum), evergreen all year round, suspended indoors, can be called an "aerial flower." The stolons it sends out from the leaf axils produce many small plantlets with roots, hanging down along the pot, very elegant. Spider plant is also called an indoor air "purifier"; it can absorb carbon monoxide, nitrogen oxides and other volatile gases, purifying the room's air and benefiting human health. However, spider plant leaf tips often wither easily, affecting its appearance. Therefore, prevention and treatment must be carried out according to the situation. 1. Always pay attention to watering and misting, keeping the pot

What are the reasons that azaleas drop their leaves and die after being watered with organic fertilizer?
After azaleas are watered with a liquid organic fertilizer that has been composted, abnormal leaf drop and death may occur for the following reasons: First, the eggshells and soybean residue may contain a small amount of table salt (sodium chloride), and the fine fibrous roots of azaleas are relatively sensitive to sodium ions, causing root rot, leaf drop, and death. Second, the 5% concentration may still be too strong for the fine hairy fibrous roots of azaleas, or the fertilizer liquid left at the end may have an even higher concentration, making it hard for the plant to withstand. Third, the timing of fertilization may be inappropriate, such as after the flowers fade, when new root tips have just emerged,

Grafting Propagation Technique for Pinus sylvestris var. mongolica Grafted with Korean Pine (Pinus koraiensis)
Pinus sylvestris var. mongolica has strong adaptability, is cold-resistant, drought-tolerant, and tolerant of poor soil. Using Pinus sylvestris var. mongolica as rootstock to graft Korean pine (Pinus koraiensis) brings earlier flowering and fruiting, rapid orchard establishment, and good results. 1 Preparation of scions 1.1 Selection of mother trees Select superior mother trees as scion sources. Within the chosen area, measure the tree height, diameter at breast height, crown width, fruiting layer thickness, number of young cones, number of cones, and male and female flower quantities of each clone individual. At the same time, conduct individual tree seed collection, and test cone number, cone weight, seed yield, seed extraction rate, kernel rate, empty shell rate, pest damage rate, 1000-seed weight, as well as cone length and width.

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

How to grow azaleas with soilless culture? Master these key technical points
1. Preparation of the substrate. Azalea roots are very fine and require a loose substrate to facilitate aeration and drainage. Mix 1 part vermiculite, 1 part perlite sand, 1 part river sand, and 1 part coal cinder in proportion. After mixing the substrate, sterilize it with a 0.1% carbendazim solution, stir it evenly into the substrate, and cover with plastic film for 1 day. Then rinse it multiple times with clean water, and after air-drying, mix it evenly with a 0.4% agricultural compound fertilizer solution, then cover with plastic film for one month, after which it can be used for potting. 2. Preparation of the nutrient solution. Azaleas have relatively strict fertilizer requirements. During the growing period, apply light fertilizer frequently.

Miniature bonsai are petite and exquisite, revealing the beauty of nature within a tiny space.
For the selection of small stumps, choose plants with strong vitality that are easy to tame into trunks and twisted, varied forms. Also pay attention to selecting varieties with small leaves, strong sprouting ability and shade tolerance. 1. Seek out old trunks and small branches of varied forms on a certain tree stump for air layering (that is, sleeve propagation), mostly carried out in early to mid-March during the plum rain season. 2. Seek out tree stumps with well-developed bare roots, and near their root area select crooked, ancient-looking, robust ones with small branches and bare roots, and separate them from the tree stump (best done in late autumn), but do not transplant them immediately; wait until the following spring when the separated plants sprout and grow branches.

Pyracantha bonsai is fiery red like fire, with high ornamental value
Pyracantha is also known as "torch fruit", "flame tree" and "soldier-saving grain". Growing wild throughout the Yunnan, Guizhou and Sichuan regions, it can be found all over the mountains, and people have long dug it up for potting and made it into bonsai for ornamental display. Its presence is also seen at the border area of northern Guangdong with Hunan and Jiangxi. After three to five years of large-scale seedling cultivation, there is a medium-to-upper-grade raw material with a circumference of twenty to thirty cm, and the resource is abundant, which is truly a good thing for closing mountains for afforestation and protecting the environment. Seedling stock can be made into all kinds of bonsai more freely and with ease. Although it is not as "wild in flavor" as wild stock, its elegance has a different

Azalea Bonsai Flower Bud Removal Techniques: How to Make the Canopy Dense and Uniform with Flat Tiers
Stump bonsai styling emphasizes clear layers, that is, the so-called "flat tiers" in bonsai styling should be distinct, giving it a natural charm, and this is especially prominent in azalea bonsai. However, in styling, the growth of the flat tiers at some layers does not always go as desired; branches within the same layer grow unevenly, and the flat tiers are not dense and uniform. For this reason, people usually carry out techniques such as pinching and topping, but the technique I am introducing now is the one most suitable for flowering bonsai: flower bud removal. The flat-tier styling of azalea bonsai is generally the horizontal-branch type. To make it lush and perfect as quickly as possible, before the azalea has bloomed its buds, remove the buds on
