Plant extract is a kind of product that takes plant as raw material, uses appropriate solvent or method. According to the use needs of the final product, through physical and chemical extraction and separation process, directional acquisition and concentration of one or more effective components in plants, without changing the structure of its effective components. The product concept of plant extracts is relatively broad. According to the different components of the extracted plants, they form glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids, etc. Herbal Extracts,Barley Grass Powder,Turmeric Extract,Rose Extract Powder Xi'an Longze Biotechnology Co., Ltd. , https://www.bestbilberry.com
Peanut summer management points
Peanut cultivation involves careful and regular weeding throughout the growing season, typically 3 to 4 times. The first weeding should be done after the seedlings have established and the plants are well above ground. At this stage, the soil should be loosened gently to avoid covering the young plants. The second weeding takes place about 15 to 20 days after planting, and at this point, deeper tilling is recommended to encourage root development. Before the rows close completely, perform a third or fourth weeding to ensure proper air circulation and prevent weed competition.
During the early growth stages, especially in spring, peanuts may suffer from drought. It’s important to water them promptly if the soil becomes dry. Proper irrigation helps maintain healthy plant growth and improves yield potential.
Once the ridges are formed, it's essential to break up the hardened soil before the final ridge shaping. Start by removing the soil between the ridges, then carefully backfill the furrows to create well-defined and compacted ridges.
A foliar application of sodium sulfite can help control excessive vegetative growth and increase pod formation. Apply 10–12 grams of sodium sulfite per mu (approximately 667 square meters) mixed with 40–50 kg of water. Make sure the solution is well-stirred and sprayed evenly on the foliage during the early flowering stage.
To further enhance plant strength, apply a paclobutrazol solution 25 days after flowering begins. Use a concentration of 50 to 100 ppm, which helps regulate plant growth and improve overall productivity.
Diseases such as bacterial wilt, stem rot, leaf spot, and rust can affect peanut crops. To manage these, use fungicides like carbendazim, thiophanate-methyl, or triadimefon. For insect pests like aphids and cutworms, insecticides such as chlorpyrifos or other approved options can be applied to protect the crop effectively.
Proper management practices, including timely weeding, watering, and pest control, are crucial for maximizing peanut yield and quality. Always follow label instructions when using any agricultural chemicals to ensure safety and effectiveness.
