Rhodium powder Rh≥99.95% Properties: silver-white metal, extremely hard, wear-resistant, also has considerable ductility Application: It can be used as raw material for electrical instrumentation, chemical industry and manufacture of precision alloys. Rhodium powder is based on the widespread use of ruthenium in the industrial industry. Since rhodium is a rare metal required by the industry, the industry price is slightly higher than that of general non-ferrous metals. Rhodium, one of the rare elements, has various uses. Rhodium can be used to make hydrogenation catalysts, thermocouples, platinum-rhodium alloys, etc. It is also often plated on searchlights and reflectors, and is also used as a polishing agent for gemstones. and electrical contact parts. precious metal XI AN RHINE BIOLOGICAL TECHNOLOGY CO.,LTD , https://www.rhinebioteches.com
How to prevent eggplant rot disease
First, agricultural prevention and control: In order to adopt crop rotation, continuous cropping with solanaceous and melon vegetables should be avoided, and continuous cropping with cruciferous vegetables and legumes can be used. In order to strengthen cultivation and management, sorghum deep ditch cultivation should be adopted to reduce the humidity in the field, and timely pruning and disease removal. Insects and residual leaves, etc., to enhance ventilation and light transmission, so that is conducive to plant growth and development, unfavorable to the occurrence of germs; do a good job in seed disinfection and ground sterilization. The second is chemical control: available 70% mancozeb 600 times, 50% carbendazim WP 500 times; once every 7-10 days, depending on the condition of continuous use 2-3 times, better control effect.
