【産業上の利用分野】
本発明はアズキ類の増収方法に関するものである。
【0002】
【従来の技術】
一般に、アズキ類を増収させる場合、窒素、燐酸、カリ等の肥料の施用、育種法による多収性優良品種の選抜が知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、肥料の施用の場合、過度の施用により倒伏を引き起こす結果、収量減を招くことがあり、肥料の効果を最大限発揮させるには栽培土壌に適合した適切な管理が必須である。また育種法による多収性優良品種の選抜の場合、年単位の時間、多くの労力を必要とするが、必ずしも飛躍的な増収は期待でない。仮に優良品種が出ても、栽培地域によって適応性が異なるために広範囲な地域において該品種を利用することは容易でない。
【0004】
【課題を解決するための手段】
このような状況下で、本発明者らは鋭意検討を行った結果、ある種の生理作用を示す植物生長調節剤を、特定な時期のアズキ類植物に茎葉散布することによって、容易にアズキ類の収量を著しく向上させることができることを見い出し本発明を完成させた。

In general, when increasing the yield of adzuki bean, it is known to apply fertilizers such as nitrogen, phosphoric acid and potassium, and to select high-yield varieties by a breeding method.
[0003]
[Problems to be solved by the invention]
However, in the case of fertilizer application, excessive application may cause lodging, resulting in reduced yield. In order to maximize the effect of the fertilizer, appropriate management appropriate for the cultivated soil is essential. In addition, in the case of selecting high-yielding varieties by the breeding method, it takes a long time per year and a lot of labor, but a dramatic increase in sales is not always expected. Even if excellent varieties are produced, it is not easy to use the varieties in a wide area because the adaptability differs depending on the cultivation area.
[0004]
[Means for Solving the Problems]
Under these circumstances, the present inventors have conducted intensive studies and found that a plant growth regulator exhibiting a certain physiological action can be easily sprayed on the adzuki bean plant at a specific time, so that the adzuki bean can be easily obtained.

These agents may be used alone or as a mixture of two or more. Of course, in the compound having an optically active isomer, an optically active isomer having a plant growth regulating activity can also be used.
[0007]
Gibberellin biosynthesis-inhibiting plant growth regulators as described above are usually formulated into emulsions, solutions, wettable powders, suspensions, etc. using liquid carriers, solid carriers, surfactants, and other formulation auxiliaries. Used as These preparations usually contain about 0.00001 to about 99.9% by weight of an active ingredient.
[0008]

Next, the time of drug application in the present invention, that is, “the period from the pollen mother cell / embryonic sac mother cell formation stage to the vase completion stage or flowering stage” will be described.
In the present invention, it is essential that the plant growth regulator as described above is foliage-sprayed on adzuki bean plants in the period from the pollen mother cell / embryo sac mother cell formation stage to the vase completion stage or in the flowering stage. Preferably, it is a period from the pollen mother cell / embryo sac mother cell formation stage to the vase completion stage or a period of four weeks from the first day of flowering. More preferably, the period is three weeks from the first day of flowering.
By the way, the flowers of the adzuki bean plant are in the growth point hypertrophy stage, flower bud differentiation stage, single flower primordium differentiation stage, aggressive / petal differentiation stage, flower organ primordium differentiation completion, pollen mother cells / embryonic maternal cell formation stage, pollen It is formed after the maternal cell / embryo maternal cell division stage, the vase enlargement phase, and the vase completion phase. During this time, although it depends on the weather, variety, cultivation conditions, etc., for example, in the case of adzuki beans, it generally takes about 25 to 30 days. Among them, the growing point hypertrophy period is about 25 to 30 days before flowering, the flower bud differentiation period is about 23 days before flowering, the single flower primordium differentiation period is about 21 days before flowering, and the gaku / petal differentiation period is about 18 days before flowering. The pollen primordium differentiation is completed about 15 days before flowering, the pollen mother cell / embryo sac mother cell formation period is about 11 days before flowering, the pollen mother cell / embryo sac mother cell division period is about 9 days before flowering, flower vase The hypertrophy elongation period corresponds to about 6 days before flowering, and the vase completion period corresponds to about 2 days before flowering. Therefore, the period from the pollen mother cell / embryonic maternal cell formation stage to the vase completion stage as referred to in the present invention is the last stage of the flower formation process in adzuki bean plants, for example, in the case of adzuki bean, before flowering It is about 1 day to about 13 days. However, such days before flowering may change depending on weather, varieties, cultivation conditions, and the like. On the other hand, the flowering period may be as long as 6 weeks depending on the weather, varieties, cultivation conditions and the like. For example, in the case of adzuki bean, it is usually about 3 to 4 weeks.

Thus, an emulsion is obtained (compound C is described in JP-A-59-196840).
Next, test examples will be described.
[0018]
Test example 1
Azuki bean (cultivar, Erimorezuki) was cultivated and, during the flowering period (52 days after sowing), a 10 ppm solution of compound A prepared as a wettable powder according to Formulation Example 2 was sprayed at a chemical treatment rate of 1000 L / ha. . After cultivation for 108 days after sowing, the yield was investigated. The yield was expressed as the grain yield, which is the product of the total number of grains per strain and the average single grain weight. Here, the total number of grains is the number of fertile ovules, and is obtained by subtracting the number of ovules having growth arrested grains that did not develop as grains during the embryonic development process from the total number of ovules. Specifically, a fertile ovule and a growth arrested grain that did not develop as a grain were selected using a 3 mm mesh sieve, and the yield was determined.
Table 1 shows the results of the yield investigation. In addition, this test was performed in 3 repetitions per section. The yield was determined by averaging three replicates and expressed as a relative value with the control (untreated) as 100%. As is clear from Table 1, the group of the present invention showed an extremely high yield increase effect as compared with the control group (untreated group).
