Problems solved by technology

[0004] The first object of the present invention is to provide a seedling strengthening agent for rice, which can effectively solve the problem that the existing acid-adjusting agents are difficult to take into account the quick-acting and slow-acting effects, not only achieve the best effect of disease prevention and seedling strengthening, but also easy to produce and easy to use. During the seedling growth period, there is no need to apply additional nutrients, chemical control agents, fungicides and acid regulators, no secondary management, saving labor and time, and reducing costs; especially suitable for the cultivation of rice seedlings in Northeast China

Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to a rice seedling strengthening agent as well as a preparation method and a use method thereof. The rice seedling strengthening agent comprises humic acid, a nitrogen-phosphorus-potassium source, an acid regulator, a plant growth regulator and a carrier, wherein the acid regulator is composed of ammonium bisulfate and citric acid in a mass ratio of 10:(1-2). Ammonium bisulfate and citric acid are compounded and combined according to a specific proportion to serve as the acid regulator, the problemthat quick acting and slow acting cannot be achieved at the same time can be solved, and the expected target is achieved. Meanwhile, other components are further optimized, so that the obtained rice seedling strengthening agent not only achieves the optimal effect of preventing diseases and strengthening seedlings, but also is easy to produce, convenient to use, free of secondary management in theseedling growth period, labor-saving and time-saving, and low in cost; and the rice seedling strengthening agent is especially suitable for planting rice seedlings in northeast China.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a rice seedling strengthening agent and a preparation method and a use method thereof. Background technique [0002] In the Northeast cold region rice-growing area, the seedling raising method is mostly dry-raising mode. Due to the influence of unfavorable factors such as open area, changeable climatic conditions, and various soil types, poor quality of seedlings often occurs in the process of dry seedling cultivation. The main manifestations are weak seedlings, that is, the seedlings have light leaf color, less root volume and slender root system; poor resistance to adversity, prone to seedling diseases; slow seedling speed after transplanting, and low tillering ability. The rice seedling strengthening agent integrates nutrition, sterilization, acid adjustment and chemical control, has the advantages of simple operation, disease prevention and seedling...
