Fluorine-Containing Methylbenzene Fluorine-Containing Methylbenzene products can be used as herbicides in the manufacture controlling wheat fields, cotton fields and other broadleaf weeds and perennial weeds. It can also be used in the manufacture of antipsychotics drugs. Containing Methylbenzene, 5-Fluoro-3-Nitrotoluene,2-Bromo-5-Fluorobenzotrifluoride Taizhou Volsen Chemical Co., Ltd. , https://www.volsenchem.com
The Fluorine-Containing Methylbenzene products must be kept under seal, once exposed to light will immediately cause discoloration. It should also be stored in a cool, ventilated warehouse, away from fire and heat. Compartment temperature should not exceed 30 ℃. And make the appropriate technical measures for fire and explosion. Products will Decomposition by high fever and emit toxic gases, such as carbon monoxide, carbon dioxide, hydrogen fluorid. Due to ts vapor is heavier than air, it can spread from low place to far away places. In case of fire conditions, should not fire with water. In case of a small amount of leakage should be evenly sprayed with dilute hydrochloric acid. In case of large spills should build a causeway or trenching asylum. The transfer pump to tankers or exclusive collector, recycling or shipped to the waste disposal sites.
Broad bean high quality and high yield cultivation management technology
1. **Variety Selection**: Choose high-quality, large-seeded varieties such as Shanghai Qingpi, Liyang Bigfoot, and Hanzhong Dayedou, which are early-maturing and high-yielding. These varieties are well-suited for different growing conditions and can significantly improve overall productivity.
2. **Crop Rotation and Field Selection**: Broad beans have strong adaptability, but it's important to avoid continuous cropping. To maintain soil health and reduce disease risk, select fields or wastelands that follow a 2- to 3-year crop rotation with rice, wheat, rapeseed, or summer eggplant. Ensure the site has good irrigation and drainage systems for optimal growth.
3. **Soil Preparation**: Deep plowing is essential to improve soil aeration and root penetration. Incorporate 5,000 kg of well-decomposed manure or organic fertilizer per acre. Mix in 25–30 kg of calcium superphosphate to enhance nutrient availability. Apply this mixture evenly before planting to ensure balanced nutrition for the crop.
4. **Seeding and Field Management**: Soak seeds for 24 hours before sowing. Treat each seed with 10–17 grams of rhizobial bacteria to boost nitrogen fixation and improve yield. Plant 2–3 seeds per hole, spacing them 40–50 cm apart, with holes 20–30 cm deep. Cover the seeds with 6% thick soil and water immediately after planting. After germination, apply a thin layer of diluted urine between rows to provide additional nutrients.
The principle of field management should focus on promoting growth while controlling excessive vegetative development. Use nitrogen-rich fertilizers like human or animal manure water to encourage deep root growth before flowering. Keep the soil consistently moist during the fruiting stage. When the plant develops around 16 nodes—marked by the appearance of 6–7 lobes on the compound leaves—prune the top to improve air circulation, reduce flowering density, extend the blooming period, prevent lodging, and promote earlier maturity and better fruit set. Pruning should be done on sunny days to avoid wound rot. Harvest when the pods are fully developed and the shell turns yellow. Dry the beans thoroughly and thresh them once ready.
This method ensures a healthy, productive broad bean crop while maintaining soil fertility and reducing environmental impact.
