Description
Technical Field
The invention belongs to the technical field of agricultural planting, and particularly relates to a rice seedling strengthening agent, and a preparation method and a use method thereof.
Background
In the rice farming areas in the northeast cold areas, the seedling raising mode is mostly a dry raising mode. Due to the influence of adverse factors such as wide regions, variable climatic conditions, various soil types and the like, poor seedling quality often occurs in the process of dry seedling raising. The seedling is mainly characterized by weak seedlings, namely the seedlings have light leaf color, less root quantity and slender root systems; the resistance to adversity is poor, and diseases in seedling stage are easy to occur; the seedling reviving speed after transplanting is too slow, the tillering capability is lower, and the like. The rice seedling strengthening agent integrates nutrition, sterilization, acid regulation and chemical control, has the advantages of simple operation, disease prevention and seedling strengthening, and the like, and has obvious yield increasing effect.
However, in the specific application process, we find that some problems exist: the acid regulating agent added in the rice seedling strengthening agent sold in the current market is concentrated sulfuric acid, the pH value of soil can be reduced from about 6 to about 5 by regulating the acid so as to meet the soil condition suitable for the growth of rice seedlings, but the acid regulating agent needs to be additionally sprayed in the later growth period of the rice seedlings because the acidity of bed soil is insufficient; or the plant growth inhibitor is used too much, so that the phenomena of small and old seedlings, the growth speed retardation caused by difficult rooting in the later period, the phenomena of soft rot, bacterial wilt, damping off and the like in the growth period of the seedlings occur; or the phenomenon of fertilizer loss caused by insufficient nutrition in the later growth period, and the like. These problems all lead to secondary management, which is labor-consuming, time-consuming and expensive.
Disclosure of Invention
The invention aims to provide a rice seedling strengthening agent, which can effectively solve the problem that the prior acid regulating agent has quick and slow effects which are difficult to be taken into consideration, not only achieves the best effect of preventing diseases and strengthening seedlings, but also is easy to produce and convenient to use, does not need to additionally apply a nutrient, a chemical control agent, a bactericide and an acid regulating agent in the seedling growth period, has no secondary management, saves labor and time and reduces the cost; is particularly suitable for planting rice seedlings in northeast regions.
The rice seedling strengthening agent comprises humic acid, nitrogen, phosphorus and potassium sources, an acid regulating agent, a plant growth regulator and a carrier; wherein the acid regulating agent consists of ammonium bisulfate and citric acid according to the mass ratio of 10 (1-2).
The research shows that the conventional rice seedling strengthening agent generally takes organic materials/fly ash as a carrier at present and is prepared into an acid regulating agent by mixing concentrated sulfuric acid (strong acid) with the concentration of about 20%; not only has high production risk, wastes time and labor, but also can not achieve the slow effect, so that the acid regulating agent is required to be additionally sprayed in the later growth stage of the seedlings because the acidity of the bed soil is not enough.
Although citric acid is added into bed soil as an acid regulating agent in the prior art, such as CN107324943A, after all, the use methods and the effects of the soil and the seedling strengthening agent are obviously different, and the citric acid directly added into the seedling strengthening agent as the acid regulating agent can show a certain slow release effect, but is not ideal and cannot meet the optimal acid soil environment for the growth of rice seedlings.
Therefore, the inorganic acid and the organic acid are compounded to serve as an acid regulating agent in an attempt to achieve the dual purposes of quick effect and slow effect, but in the prior art, a large number of inorganic acids and organic acids can be selected, and the proper compounding of the inorganic acid and the citric acid is difficult to screen by inquiring tool books and existing documents.
After intensive research, the ammonium bisulfate and the citric acid are selected to be compounded, and the problem that the existing acid regulating agent cannot give consideration to quick effect and slow effect is solved by controlling the proportional relation of the dosage of the ammonium bisulfate and the citric acid, so that the expected target is achieved; the ammonium bisulfate is solid, and has the advantages of low cost and easy addition; the compounding mode of the acid regulating agent is one of the invention points of the invention.
The pH value of the rice soil is between 4.5 and 5.5, which is beneficial to the growth of rice seedlings, but the acid regulating mechanisms of the quick-acting acid regulating agent and the slow-release acid regulating agent are different, so that the growth of the rice seedlings is substantially influenced if the application amount of the acid regulating agent is not properly controlled. Therefore, the actual research shows that the acid regulating agent is controlled to be 2-10% of the rice seedling strengthening agent by mass percent, so that the quick-acting and slow-release effects can be realized, and the pH value of the rice soil is ensured to be more stable between 4.5 and 5.5. Within the range, the floating adjustment can be carried out according to the actual soil condition. Preferably, the mass fraction of the acid regulating agent relative to the rice seedling strengthening agent is controlled to be more than 5%, such as 5-10%, so that the acid regulating agent not only has good slow-acting and quick-acting effects, but also saves the cost and avoids waste.
In order to further improve the implementation effect of the rice seedling strengthening agent, the invention also carries out deep research on the plant growth regulator. The research shows that the existing plant growth regulator has more optional components and different functional emphasis points, so that the cost is increased due to the fact that a large amount of plant growth regulator is added into the existing rice seedling strengthening agent. Therefore, through deep research and analysis, components of paclobutrazol, potassium indolebutyrate, chitosan oligosaccharide, seaweed extract and mineral potassium fulvate which can generate obvious synergistic effect are screened out and mixed according to a specific mass ratio to form the plant growth regulator with high cost performance.
Preferably, the plant growth regulator is prepared from paclobutrazol, potassium indolebutyrate, chitosan oligosaccharide, seaweed extract and mineral potassium fulvate in a mass ratio of 1:1: (5-8): 10: (20-30). Based on paclobutrazol and potassium indolebutyrate, chitosan oligosaccharide, seaweed essence and mineral potassium fulvate are added, and the cooperation of the five components can improve soil, enhance the seedling root coiling capability, promote the seedling to be sturdy, have strong stress resistance, improve the seedling rate, accelerate the seedling reviving and rooting speed, improve the early-maturing capability of the transplanted seedlings, obtain multiple effects and lay a good foundation for high yield and high quality of rice in northeast China.

As one embodiment of the present invention, in the plant growth regulator, the mass ratio of paclobutrazol, potassium indolebutyrate, chitosan oligosaccharide, seaweed extract and mineral potassium fulvate is 1:1:8:10:30, and the synergistic effect is better when the mass fraction of the paclobutrazol and the potassium indolebutyrate is 0.05-0.1%.
The nitrogen, phosphorus and potassium source is prepared from monoammonium phosphate, ammonium sulfate and potassium sulfate according to the mass ratio of (12-16): (35-40): (8-12); preferably, the mass ratio of the monoammonium phosphate to the ammonium sulfate to the potassium sulfate is 15:39:10, and the nitrogen, phosphorus and potassium nutrients are better synergistic with other components.
Preferably, the support is a zeolite powder.

As one embodiment of the invention, the rice seedling strengthening agent comprises the following components in parts by weight: 14-20 parts of humic acid; 12-16 parts of monoammonium phosphate; 35-40 parts of ammonium sulfate; 8-12 parts of potassium sulfate; 1-5 parts of plant growth regulator; 2-10 parts of an acid regulating agent; 4-12 parts of zeolite powder; wherein in the plant growth regulator, the mass ratio of paclobutrazol, potassium indolebutyrate, chitosan oligosaccharide, seaweed extract and mineral potassium fulvate is 1:1:8:10:30, of a nitrogen-containing gas; in the acid regulating agent, the mass ratio of ammonium bisulfate to citric acid is 10: (1-2).
In order to further improve the using effect of the rice seedling strengthening agent, the rice seedling strengthening agent also comprises trace elements and/or bactericides.
The trace elements may be conventional trace elements known to those skilled in the art, and preferably zinc or silicon is added.
The bactericide used in the field is a mature product and can be selected according to rice seedling diseases, but in order to improve the cost performance, the bactericide is further optimized and adjusted. The bactericide is prepared from hymexazol, metalaxyl and sodium diquat according to the mass ratio (1-3): (1-2): 1.
As one of the specific embodiments of the invention, the rice seedling strengthening agent comprises the following components in parts by weight: 14-20 parts of humic acid; 12-16 parts of monoammonium phosphate; 35-40 parts of ammonium sulfate; 8-12 parts of potassium sulfate; 4-6 parts of trace elements; 1-5 parts of plant growth regulator; 0.1-1 part of bactericide and 2-10 parts of acid regulator; 4-12 parts of zeolite powder. Through the specific selection and the compounding of the dosage of each component, the obtained rice seedling strengthening agent has the advantages of combining quick-acting effect with slow-acting acid regulation and integrating nutrition, sterilization, acid regulation and chemical control into a whole, thereby achieving the best effect of preventing diseases and strengthening seedlings, having no secondary management, saving labor and time and reducing the cost; is particularly suitable for planting rice seedlings in northeast regions.
