The present invention relates to a combination preparation for regulating plant growth that is stable in soil and is made by mixing nicotinamide and an inorganic salt containing any one of sodium, potassium, calcium, or magnesium. It is known that nicotinamide and its related compounds have plant growth regulating effects (Tokuko Sho
50-26451), and has recently been used for agricultural and horticultural purposes. For example, in order to grow healthy seedlings in rice seedling box cultivation, methods include mixing a nicotinamide-containing powder prepared by mixing with a carrier such as diatomaceous earth or clay with the soil, or spraying it on the soil as an aqueous nicotinamide solution. A method is being taken. However, in any of these cases, nicotinic acid amide disappears in the soil in a short period of time, resulting in poor expression of plant growth regulating action, which is a major practical drawback. As a result of researching the stability of these nicotinic acid amides in soil, the present inventors found that by mixing them with inorganic salts, nicotinic acid amides do not disappear in a short period of time and the plant growth regulating effect is stabilized. It was found that this phenomenon occurs. The present invention is based on this knowledge. The inorganic salt used in the present invention is preferably an inorganic salt containing sodium, potassium, calcium and magnesium, such as sodium nitrate,
Sodium bicarbonate, sodium borate, sodium carbonate, sodium chloride, sodium dihydrogen phosphate, sodium monohydrogen phosphate, sodium sulfate, sodium thiosulfate, potassium sulfate, potassium nitrate, potassium bicarbonate, potassium borate, potassium carbonate, chloride Potassium, monopotassium phosphate, dipotassium phosphate, calcium chloride, calcium nitrate, calcium sulfate, calcium hydroxide, calcium carbonate, calcium dihydrogen phosphate, calcium monohydrogen phosphate, calcium trihydrogen phosphate, magnesium chloride, nitric acid Examples include magnesium, magnesium phosphate, and magnesium sulfate. These inorganic salts can also be added in the form of fertilizers, such as sodium nitrate fertilizer, nitrate lime fertilizer,
Lime nitrogen fertilizer, magnesium sulfate ammonia fertilizer, superphosphate lime fertilizer, heavy superphosphate lime fertilizer, magnesium superphosphate lime fertilizer, molten phosphorus fertilizer, calcined phosphorus fertilizer, precipitated phosphate fertilizer, mixed phosphate fertilizer, humus Acid mixed phosphorus fertilizer, by-product phosphorus fertilizer, potassium sulfate fertilizer, potassium chloride fertilizer, potassium sulfate magnesium fertilizer, bittern potassium salt fertilizer, processed bittern potassium fertilizer, potassium bicarbonate fertilizer, humic acid potassium fertilizer, potassium silicate fertilizer,
By-product potassium fertilizer, quicklime fertilizer, slaked lime fertilizer, calcium carbonate fertilizer, by-product lime fertilizer, mixed lime fertilizer, fossil shell fertilizer, silicate acid fertilizer, magnesium sulfate fertilizer,
hydroxide magnesium soil fertilizer, by-product basic magnesium soil fertilizer, processed magnesium soil fertilizer, humic acid magnesium soil fertilizer, manganese sulfate fertilizer, sulfated magnesium soil fertilizer, mined manganese fertilizer, borate fertilizer, fused boron fertilizer, Added magnesium soil boron fertilizer,
Examples include trace element mixed fertilizer, melted trace element composite fertilizer, liquid trace element composite fertilizer, crushed lime fertilizer, calcium chloride fertilizer, and the like. When the compounded preparation for regulating plant growth of the present invention is used as a plant growth regulating agent for agriculture and horticulture, it can be applied directly or prepared into granules, powders, etc. using a suitable solid carrier, liquid carrier, emulsifying dispersant, etc. It can be applied in any form such as emulsion, wettable powder, tablet, oil solution, spray, atomizer, etc. Furthermore, the compounded preparation for regulating plant growth of the present invention may contain or be used in combination with other inorganic salts, inorganic fertilizers, organic fertilizers, insecticides, fungicides, herbicides, etc. Moreover, it is also good to mix the compounded preparation of the present invention with soil and process it with soil. The blending ratio of nicotinic acid amide and inorganic salt in the present invention varies depending on the method of use, but generally 0.1 to 50 parts of inorganic salt to 1 part of nicotinic acid amide.
parts, preferably 1 to 30 parts. In addition, when making culture soil, it is preferable to mix 2 to 40 parts of soil to 1 part of this preparation. Examples and test examples of the present invention are shown below. Example 1 1 part nicotinamide, 10 parts monocalcium phosphate
1 part, 6 parts of calcium sulfate, and 83 parts of clay are thoroughly mixed and ground to make a powder. Example 2 1 part of nicotinic acid amide, 4 parts of potassium chloride, and 95 parts of clay were thoroughly mixed and pulverized to form a powder. Example 3 1 part nicotinamide, 6 parts calcium sulfate, 10 parts monocalcium phosphate, 4 parts potassium chloride, 79 parts clay
Mix and grind thoroughly to make a powder. Example 4 20 parts of nicotinamide and 80 parts of potassium sulfate were added to water.
Dissolve in 100 parts to make a liquid preparation. Example 5 4 parts of nicotinamide, 13 parts of magnesium superphosphate
1 part and 83 parts of clay were thoroughly mixed and ground to make a powder. Example 6 2 parts of nicotinamide, 2 parts of calcium carbonate fertilizer
part, 7 parts of lime superphosphate, 0.5 parts of kasugamycin,
Mix and grind 88.5 parts of clay thoroughly to make a powder. Example 7 1 part nicotinamide, 9 parts sodium nitrate,
Thoroughly mix and grind 90 parts of clay to make a powder. Example 8 Clay was added to 3 parts of nicotinamide, 12 parts of potassium chloride, 48 parts of superphosphate lime fertilizer, and 1 part of Solpol 7080 (surfactant manufactured by Toho Chemical Co., Ltd.) to make 100 parts, and the mixture was thoroughly mixed and ground. Use as a hydrating agent. Example 9 50 parts of nicotinic acid amide and 50 parts of Hyponex (manufactured by Hydroponic Chemical Co., Inc.) were thoroughly mixed and ground to form a powder. Test Example 1 0.4g of powders of Examples 1, 2, 3, and 7, Example 5
0.1 g of the powder of Example 6 and 0.2 g of the powder of Example 6 were added to 10 g of paddy soil and mixed uniformly. As a comparison agent, a 1% nicotinamide powder was prepared by mixing and pulverizing 1 part of nicotinamide and 99 parts of clay.
0.4g was added to 10g of paddy soil and mixed. These nicotinic acid amide-containing soils were packed into seedling boxes and stored in a wet dark place at 27°C for 5 days.
After 5 days, each sample was extracted from the soil with 60% acetone water, and after separating nicotinic acid amide using thin layer chromatography, the OD value was measured using a spectrophotometer and the volume was made constant with water. The amount of nicotinamide was determined from the nicotinamide test line prepared in advance, and the residual rate was calculated. The results are shown in Table 1. In the soil area where no inorganic salt was added to nicotinic acid amide, the residual rate of nicotinic acid amide was 54%, whereas in Examples 1, 2, 3, and 5, the residual rate of nicotinic acid amide was 54%. , 6 and 7, most of the nicotinic acid amide remained.

[Table] Test Example 2 Using C 14 -nicotinamide in which the carbon atom of the carbonyl group was labeled with radioactive carbon, a powder having the same composition as in Example 3 and 1 part of C 14 -nicotinamide and 99 parts of clay were prepared. A powder containing no inorganic salt was prepared and subjected to the following tests. 0.4 g of each powder (4 mg of C 14 -nicotinamide, containing 3.4 microcuries as radioactivity) and ±10 g of dry heat sterilization were mixed uniformly in a glass container, and humidified with 10 ml of sterile distilled water. After that, it was left in the dark at 27°C. Radioactive carbon dioxide gas generated by the decomposition of C 14 -nicotinamide was introduced from these containers into a 2N aqueous sodium hydroxide solution using a glass tube and absorbed, and measured using a liquid scintillation spectrometer. At the same time, each soil was extracted with 60% acetone water, and the extract was placed on an Avicel thin layer plate with n-propanol/water (8:1, primary).
and n-butanol/water/ammonia (8.6:1.4:
Perform a two-dimensional expansion using a solvent system of 0.5, quadratic),
Radioactive substances were confirmed by autoradiography. As shown in FIG. 1, when no inorganic salt was blended as a comparative example, about 60% of nicotinic acid amide was decomposed and decarboxylated on the 7th day. It was also confirmed that of the approximately 40% radioactive substances remaining in the soil, 65% was nicotinic acid and 35% was nicotinamide. Decomposition continued thereafter, and on the 28th day, the added C14
- Approximately 89% of nicotinamide underwent decarboxylation.
On the other hand, when inorganic salts were added, the generation of carbon dioxide gas was extremely slow, and on the 7th day, about 15% of the nicotinic acid amide added
%, approximately 40% underwent decarboxylation at 28 days. In addition, the radioactive substances in the soil in this case are mostly nicotinamide even on the 28th day, and the amount of nicotinic acid is 10
% or less. In this way, it has become clear that when nicotinic acid amide is used alone, nicotinic acid amide is rapidly deaminated in the soil to become nicotinic acid, which is further decarboxylated and decomposed. When nicotinamide and an inorganic salt were blended, the progress of this decomposition was clearly reduced.
