Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an agent for increasing the yield of agricultural products.

[0002]

2. Description of the Related Art It is an important issue in agricultural production to promote the growth of crops and increase the yield by increasing the yield per unit area. Normally, nutrients such as nitrogen, phosphorus, and potassium, which are essential for plant growth, and trace metal elements are supplied to plants after being added to the original fertilizer and topdressing. There is a limit to improving the growth amount and yield of crops even if the amount of nutrients is increased.Moreover, the use of a large amount of fertilizers causes an excess of nutrient elements in the soil, resulting in a poor absorption balance, resulting in plant growth stagnation, etc. In addition, problems such as the inability to achieve the desired increase in the yield and the inability to improve the quality such as the sugar content (Brick. Value) and freshness (greenness) occur. Under such circumstances, various plant growth regulators are used in combination.

[0003]

As plant growth regulators such as gibberellin and auxin, plant growth regulators such as germination, rooting, elongation, flowering, fruit set and the like, and regulation of morphogenetic reactions are known. However, the action of these substances is multifaceted and complex, and their use is limited. In addition, a foliar spray using an oligosaccharide (Japanese Unexamined Patent Publication No. 9-322647) or a liquid fertilizer containing a sugar, a mineral, an amino acid, a seaweed extract, or a fermented extract of microorganisms may be sprayed on a foliage or subjected to solution fertilization. However, it is not practically sufficient to increase the yield of agricultural products. Also, Japanese Patent Application Laid-Open No. 55-406
No. 74 discloses that an alcohol having 30 carbon atoms is used as a plant growth promoter, but the effect of increasing the yield of agricultural products is not sufficient. Also, Japanese Patent Application Laid-Open No. 2000-198703 discloses a plant activating agent comprising a monohydric alcohol having 12 to 24 carbon atoms, but does not mention a final increase in yield or improvement in quality of agricultural products.

[0004] It is an object of the present invention to provide a crop increasing agent which has a remarkable effect on increasing the yield of various crops.

[0005]

EXAMPLES Example 1 (Effect on Paddy Rice) A test was conducted to test the effect of increasing the yield using paddy rice 'Koshihikari' under the following treatment conditions. Two treatments were performed, i.e., the tillering stage and the panicle formation stage, using the crop-producing agents shown in Tables 1 and 2. The treatment amount was set such that the water depth of Honda was 5 cm, and the concentration of the component (A) in the crop enhancer in Tables 1 and 2 in water was 5.0 ppm (weight ratio). Brown rice yield and yield components at harvest (number of ears per strain, number of paddies per ear, ripening rate, 1,000 grain weight)
investigated. In addition, the measured value was compared with the relative value when the untreated section was set to 100. The results are shown in Table 3. In the case of using the crop-producing agent of the present invention, the number of panicles per strain, 1
It can be seen that the number of paddies per ear, the ripening rate, and the yield component of 1,000 grain weight are increased as compared with the control plot, and the effect of increasing the yield is obtained.
