Rape deficiency due to boron deficiency
Lao Zheng of Zhuoxun Village, Yundian County, Yunmeng County asked: Why did the base of the blade appear red cracks before drawing? Why do pods appear when seeding? A: Some rapeseeds show that the roots and necks of the leaves of the sunny side are enlarged and the cortex is cracked, showing purple-red cracks, and developing upwards and downwards. The leaves are thick and brittle, the tip of the leaf is rolled down, the buds are green and yellow, some are withered, the petals are shrunk, and the flowering is not normal. The appearance of this symptom indicates that the application of boron fertilizer was neglected in the potential boron deficiency of the soil or the base fertilizer. Rapeseed is very sensitive to boron fertilizer, and adding boron fertilizer can greatly increase yield. The boron fertilizer should be sprayed outside the roots in the middle and late stages of management. It can be sprayed with a 0.1% to 0.2% borax solution or a 0.1% to 0.15% sule boron solution.

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.xianrhinebiotech.com
