Abstract

The invention discloses a rooting agent used for transplanting tobacco crops and playing a role in resisting diseases and promoting growth. The rooting agent comprises the following ingredients in parts by weight: 40-45 parts of a compound microorganism bacterium agent, 20-25 parts of fulvic acid potassium, 40-50 parts of fulvic acid and 1-2 parts of sodium alginate. The rooting agent is simple in process, reasonable in composition proportion and convenient to use, can effectively solve various problems of long seedling returning period, lowering of root activity and the like after tobacco seedlings are transplanted, and can prevent plant diseases and insect pests and improve the drought resistance of the crops. The ingredients of the rooting agent for transplanting does not contain artificially synthesized hormone. Compared with a traditional transplanting method, the rooting agent for transplanting has the advantages that the seedling returning period of large fields is shortened, the growth of lateral roots is promoted, the active absorbing area of the roots is increased, the physiological metabolism strength in the roots can be improved, the disease resistance of tobacco seedlings is improved, and the transplanting survival rate is enhanced.

Description

technical field

[0001] The invention relates to the technical field of agricultural medicaments, in particular to a rooting agent with disease-resistant and growth-promoting effects for transplanting tobacco crops. Background technique

[0002] Intensive, light and simplified seedling cultivation of tobacco in China has been initially formed, and floating seedling cultivation is the main method, which has basically realized the production of high-quality, efficient and strong seedlings. Transplanting is one of the key links in flue-cured tobacco production, marking the end of the flue-cured tobacco seedbed period and the beginning of the field period. However, there are still many problems in the tobacco seedlings of the current intensive floating seedling cultivation of tobacco, such as long return period, susceptibility to diseases, and poor stress resistance of the tobacco seedlings. Due to the root breaking caused during transportation and artificial transplanting, and ...
