Embodiment 1
[0023] (4) Best Example 1: formula per ton
[0024] Ammonium sulfate 580 kg Ammonium phosphate 160 kg
[0025] Potassium chloride 40 kg Zinc sulfate 20 kg
[0026] Ferrous Sulfate 20kg Metalaxyl 10kg
[0027] Paclobutrazol 1 kg Naphthalene acetic acid humic acid synergist 70 kg
[0028] Auxiliary organic fertilizer 100 kg
Embodiment 2
[0029] (5) Best Example 2: formula per ton
[0030] Ammonium sulfate 590 kg Ammonium phosphate 160 kg
[0031] Potassium chloride 44 kg Zinc sulfate 30 kg
[0036] Ammonium sulfate 500 kg Ammonium phosphate 130 kg
[0037] Potassium chloride 42 kg Zinc sulfate 20 kg
[0038] Ferrous Sulfate 15kg Metalaxyl 12kg
[0039] Paclobutrazol 1 kg Humic Acid Naphthalene Acetic Acid Synergist 130 kg
[0040] Auxiliary organic fertilizer 150 kg
[0041] After the above-mentioned components are processed into a root-strengthening and seedling-promoting agent, they are layered with rice seeds and sown into the soil, and then watered, which can promote the uniformity of the seedlings and effectively prevent the occurrence of blight at the seedling stage. Through comparison and measurement, compared with the conventional method, the emergence rate can be increased by 13.3%, the number of adventitious roots can be increased by 23.2%, the dry weight of full-term seedlings can be increased by 26.4%, and the yield per mu can be increased by 12.3%.

Abstract
The invention relates to a dry-cultured paddy rice growth promoting and seedling strengthening agent comprising effective components of, by weight: 60 to 80% of an acidic NPK fertilizer, 0 to 5% of a trace fertilizer, 0.5 to 2.5% of a bacteriostatic preparation, 5 to 15% of an acidity regulating synergist, 0.05 to 0.15% of a chemical regulating preparation, and 5 to 15% of an organic auxiliary agent. When the agent provided by the invention is used on paddy rice directly sowed on dry paddy fields, the seedlings are well-arranged and strong, and are not separated from fertilizers. The roots of the paddy rice are well developed, and the resistances of the paddy rice are high. With the disease preventing function of a special bactericidal agent, manifestations and root causes of diseases can both be treated, and occurrences of rice seedling drooping diseases and bacterial wilts can be effectively prevented. As a result of demonstrational applications of the growth promoting and seedling strengthening agent in 500 acreages of fields in two years, disease preventing and seedling strengthening effects of the agent is substantial. The development and popularization of the agent assist in filling up a gap in domestic researches, and provides a positive effect in the popularization of a paddy rice direct dry sowing technology.
Description
technical field [0001] The invention relates to a multifunctional fertilizer used in farmland, in particular to an agent for promoting growth and seedling growth of dry-sowed rice. Background technique [0002] Compared with seedling cultivation and transplanting, rice dry direct seeding technology has the advantages of water saving, labor saving, labor saving, simple operation, cost saving and efficiency increase, etc., and has been fully promoted in rice growing areas across the country. However, disease prevention, strong seedlings, and growth promotion at the seedling stage after seed germination have become technical bottlenecks in the popularization and application of dry-directed rice; Often occurs in cultivation. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a dry-sowing rice growth-stimulating and seedling-stimulating agent with multiple functions such as balanced nutrition, soil di...
