Water management: The water management of the chrysanthemum growth period must be carried out in accordance with the principle of “watering in time and timely drainage when dryâ€. And to ensure adequate water before and after the gestation period. Watering can also be combined with fertilization, but also pay attention to "see wet and dry", that is, it is not suitable for semi-dry and semi-wet, nor should it be too dry and too wet. There is also the spraying of leaf water once a day in the morning and evening. Control fertilization: Chrysanthemum growth should be applied to organic fertilizer (usually as a base fertilizer). In the vegetative growth period, topdressing is mainly based on nitrogen fertilizer, and it can be combined with some phosphorus, potassium fertilizer and trace element fertilizer. This can make the chrysanthemum branches thick and straight and can make the leaves hypertrophy. In the middle and late stages of chrysanthemum cultivation, the topdressing should be based on phosphorus and potassium fertilizers, and the special fertilizer for flowers can also be applied. The method of fertilization can be combined with soil top dressing and root top dressing, and watering should be done in time after fertilization. Note that if the chrysanthemum leaves are small and thin, and the leaves are yellow, a 0.1% urea solution can be applied multiple times. Placement and lighting: The daily management of potted chrysanthemums, in addition to the above soil, fertilizer and water management, according to the growth and environmental conditions of potted chrysanthemums, timely management measures such as turning basins and pulling pots to avoid the growth of potted chrysanthemums due to light and other reasons. development. It should be noted that the chrysanthemum is a short-day plant. The experiment shows that the chrysanthemum grows vegetatively under the long daylight of 14.5 hours per day. The darkness of more than 12 hours per day and the night temperature of 10 °C are suitable for flower bud development. Disclaimer: Some articles on this website are transferred from the Internet.

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.rhinebiotech.com
The chrysanthemum substrate is preferably a slightly acidic, loose and fertile slightly acidic sandy loam. Generally, river sand with good water permeability and good permeability is used, and it is prepared by adding garden soil and humus soil. The proportion is humus soil: garden soil: river sand = 4:4:2, if conditions permit, it is best to use disinfectant such as formalin or carbendazim to spray disinfection soil according to the instructions for disinfection.
