Abstract

The invention provides a seedling strengthening agent used for drily-raised rice in a cold region and applied to a seed bed in a liquid application manner. The seedling strengthening agent comprises an organic matter, a mixed fertilizer containing nitrogen, phosphorus and potassium, a bactericide and an acid adjusting agent, wherein the total amount of quick-acting nitrogen, phosphorus and potassium in the seedling strengthening agent is 200 to 300 g / kg, the content of quick-acting nitrogen is 80 to 150 g / kg, the content of quick-acting phosphorus is 50 to 70 g / kg, the content of quick-acting potassium is 30 to 220 g / kg, the content of the bactericide is 5 to 35 g / kg, and the content of the acid adjusting agent is 20 to 90 g / kg. The seedling strengthening agent provided by the invention changes the tradition application method of blending of a seedling strengthening agent and alien earth; the prepared seedling strengthening agent is diluted with water and uniformly sprayed on a bed surface, so the application method has the advantages of conservation of time and labor, simple operation, uniform distribution, capacity of preventing diseases, strengthening seedlings, realizing fast reviving and early tillering and increasing yield and income, etc.; and in particular, the seedling strengthening agent has better advantages in winning farming time and improving technical operation standards in drily raising rice in cold regions.

Description

Technical field [0001] The invention relates to the field of agricultural production, in particular to a seedling-strengthening agent for rice seedlings in cold areas and a method of use thereof. Background technique [0002] At present, there are more than 70 manufacturers of seedling strengthening agent in the market, with more than 40 varieties. It is roughly divided into two types: Type I and Type II. Type I strong seedling agent means that the product specification is a bag (not sub-packaged), there is no separate acid pack and medicine bag, and its pure NPK content is required to be ≥15%. Many of the strong seedling agents registered for use on fertilizers belong to Type I; Type II seedling strengthening agent means that the product specification is three or two packs in one bag, with separate acid pack and medicine pack, and its pure NPK content is required to be ≥4.5%. The pure NPK content indicated on the packaging bag of type II strong seedling agent refers to the pur...
