The medium for planting orchids is very acid-prone. How do you overcome it? After planting orchids with aquatic plants, the plants become contaminated with acids that produce organic acids after a few days, and then the orchid roots are prone to blackheads (Fusarium infection). The medium for planting orchids is boiled with water or sterilized by sterilization in a sterilization tank. Why can't the problem of orchid blackheads be completely overcome? Some orchids boiled or high temperature sterilized aquatic plants and planted orchids. Although they can temporarily kill bacteria and eggs, they still cause acidity after planting and cause blackheads in orchid roots. This is because orchids are still produced after planting. Organic acid caused by bacterial contamination. How can black orchids be reduced by planting orchids? The phenomenon of blackheads in orchid roots is mainly caused by the contamination of medium plants with bacteria that produce organic acids, resulting in acidification of the medium and the proliferation of Fusarium (Fusarium grows best around PH 4 ). It is therefore possible to increase the pH of the medium to reduce the incidence of Fusarium. infection. How to reduce the effective reduction of blackheads? Application of small molecules of water-soluble chitin and actinomycetes diluted with water 2000 times watering orchids, can effectively reduce the phenomenon of orchid blackheads. Water and grass and other media are diluted 1000 times with small molecules of water-soluble chitin and actinomycetes soaked for 1-5 minutes and can be planted after draining. What is the small molecule water-soluble chitin? What are the benefits of orchids? Chitin is very widely distributed in nature. For example, shells of crustaceans (shrimps, crabs, etc.), shells of insects (clams, butterflies), shells of molluscs (clams, oysters), and endoskeletons (squids) all contain chitin. After the calcium and protein are removed by acid-alkali treatment, chitin is obtained, and chitin is treated with high-temperature and high-alkali treatment to obtain chitosan, chitin, chitosan. Collectively referred to as chitin. Chitin in the use of orchids advantages: 1, so that the media can be connected with chitin for beneficial media microorganisms: such as actinomycetes increased, so that harmful bacteria: Fusarium (Fusarium) reduction, and can eliminate root-knot nematodes , to reduce the troubles of media continuous obstacles. 2. Promote wound healing and development in the roots, increase root hair and increase nutrient absorption. Promote plant growth. 3. Inducing the production of phytoalexins (Phytoalexin), improving crop resistance to diseases and antibacterial activity to reduce pesticide use. 4, increase the calcium content of orchids, can increase the stiffness. 5, to increase the absorption of trace elements to increase the reducing sugar content of leaves, early harvest, improve quality, extend the preservation period. Actinomycetes are extremely common gram-positive bacteria in the soil of nature, and more than 400 species are known. Because most of them have the ability to produce antibiotics, they have been applied to the control of crop diseases, from the earliest 1943 years. Waksman's report for the past year has been more than half a century. Similar cases of successful development are mostly based on the production of antibiotics. The most well-known cases are the use of Streptomycin (streptomycin) in the treatment of a variety of fruits and vegetables and bacterial diseases. In addition, actinomycetes can also decompose organic matter and produce extracellular enzymes to decompose protein, cellulose, lignin, and crab shells. Therefore, this property can be used to deal with microorganisms with chitin cell walls. For example, adding chitin to the soil can control Fusarium, mainly because the chitinase enzyme secreted by actinomycetes can cause the dissolution of pathogenic mycelium. What are the benefits of using small molecules of water-soluble chitin and actinomycetes on orchids? At the same time, using chitin and actinomycetes to water orchids, chitin has a bacteriostatic effect and can promote the growth of actinomycetes, inhibit the growth of Fusarium, and promote wound healing, for example, carbon sickness causing black spots is very effective. What is the effect of ethylene on orchids? Orchids are very sensitive to ethylene, as long as 0.01ppm of ethylene can promote Vanda orchid flowers. Second, Southeast Asia is the second largest. Dendrobium, Phalaenopsis, Slipper orchid again, Oncidium is not sensitive to ethylene, the production of Phalaenopsis by 0.09PPM ethylene treatment, you can induce aging, resulting in flower loss and loss of water wilt and other aging symptoms. Ethylene promotes wilting of the tip of the orchid bract and redness of the lips. The early symptoms of aging are transparent buds and petals, and then the veins are prominent and separated, resulting in the loss of small flowers. In addition, the sensitivity of flowers to ethylene increases with maturity or after dehydration, high temperatures, and diseases. Why does the potted orchids in the process of storage contain yellow fallen flowers during storage and transportation? The long-distance loss of lotus seedlings containing leaves and leaves was mainly due to the high ethylene concentration and bacterial infection. How to avoid the leaves from falling yellow flowers? At the center of the geometrical shape of the packaging carton or where it is most sensitive to ethylene, a small packet of ethylene absorbent is placed to suck out the ethylene produced by the flowers in the carton. Or use the 1-Methylcycopropene (MCP) EthylBloc fumigation council hours. Do not share a room with fruit that will produce a lot of ethylene. What are the effects and benefits of using ethylene absorbers? 1. Ethylene absorbent can absorb the ethylene released from fresh fruits, vegetables and flowers, inhibiting the phenomenon that plants continue to age, soften, turn yellow, fade, and fall. 2. Improve product quality - If the ethylene absorber is used properly, it can absorb most of the ethylene, so it can harvest flowers with higher maturity, ie brighter flowers, so the products shipped to the market will get a better condition. 3, long-distance transportation to reduce costs - Cocoa resistant to long-distance transport and more economical mode of transport, or can be transported by sea to take the sea instead. When do I need to change ethylene absorbent? The fresh ethylene absorber is purple-red. After oxidation of the ethylene absorber, the appearance turns brownish black and gradually extends to the center of the ethylene absorber. Ethylene absorbent packaging methods and scope of application Ethylene absorbent has different packaging methods. It can be placed in the air passage of the storage room (using wave type) so that air flow around the product or in a mini-packaging in the packaging box or bag Causes the absorbent to control the harmful ethylene gas, so that fresh products increase storage and transportation deadlines. In the winter greenhouse, the flowers are easy to grow dark spots and tend to veins prominence, off the floor, resulting in small flower buds off, how to avoid? Especially in North China, the winter greenhouse is dense, the humidity is extremely high, and the flowers are prone to black spots (brown mold) and tend to be prominent in veins. They are generated in layers, resulting in the shedding of florets. They can be diluted by 1000 times with Yongxin Antimicrobial Agent and used. Wave-type ethylene absorbers hang in the air circulation. How to deal with orchids transported with fleas? Use Yongxing orchid bagging, one side non-woven (breathable), one side PP film (transparent) and use a mini-pocket of ethylene absorbent (6MG/pack) together in a cardboard box.
Goji Berry ( [Goji" means [happy") , also called wolfberry, has been used for thousands of years by herbalists in China to protect the liver, help eyesight, boost immune function, improve circulation, and promote longevity and overall well being. It has only recently gained popularity in the west, it has become so polar, in fact, the Time Magazine recently named the Goji berry as [super-fruit" of the year. A big reason why Goji berries have quickly become a favorite nutritional supplement is that its impressive list of ingredients. The Goji berry, also called the wolfberry, is a bright purplish red or purple red berry that comes from a shrub that is native to China. In Asia, goji berries have been eaten for generation in the hope of living longer.
