Some growers like to grow soil to 30-40 cm or even higher when they grow red pomelo. They think that doing so is conducive to the growth of red meat and pomelo, but it is not. The harm of Gao Peituu lies in: First, it affects the normal breathing of the red meat honey root; Second, it limits the activities of aerobic bacteria in the soil inside the hole, making it impossible to decompose the organic matter in the soil into inorganic substances that can be absorbed by the root, reducing the roots. The amount of these inorganic materials to be fed to the leaves; the third is to affect the normal growth of the red meat pomelo; the fourth is to make the roots of the tree roots new roots, ie double roots, resulting in limited water, fertilizer, and space in the caves to compete for roots in the upper and lower layers. status. When the new roots were dry in autumn, they were killed due to lack of water in the soil, resulting in massive loss of nutrition.
Of course, when cultivating red meat and pomelo, too little earth will severely limit the normal growth and development of the roots, thereby affecting the growth of trunks, branches and leaves. In the rainy season, red meat pomelo will be planted in the tree planting hole and the roots Dipping to death will make red meat honey grapefruit freeze to death on winter ice and snow. The normal height of earth is 10 cm above the ground and should not be compressed.
Fluorine-Containing Benzonitrile
Most products of Fluorine-containing Benzonitrile is a colorless transparent liquid and has a pungent odor. It was widely used in pesticides, pharmaceuticals liquid crystal material manufacturing. High efficiency, low toxicity and residue characteristics. Through extensive research and production practice, we have found some good manufacturing processes of fluoro-containing cyanophenyl products. In addition, we have groundbreaking research on ratio of raw materials, solvent selection, the choice of solvent concentration, related use of catalysts..
