本発明は化成肥料に関し、例えば水稲用根付肥として最
適な化成肥料に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chemical fertilizer, for example, a chemical fertilizer that is optimal as a rooting fertilizer for paddy rice.
現在、寒冷地で水稲を機械移植する場合には、田植え前
に基肥を施し、次いで苗移植後に根付肥を施している。Currently, when paddy rice is mechanically transplanted in cold regions, a basal fertilizer is applied before planting, and then a rooting fertilizer is applied after transplanting the seedlings.
この根付肥を施した場合には、移植苗の初期成育が促進
されると共に、初期茎数が増加する等の効果がある。When this rooting fertilizer is applied, there are effects such as promoting the initial growth of transplanted seedlings and increasing the initial number of stems.
従来、根付肥として窒素分単独の肥料（例えば硫安）が
使用されていた。Conventionally, fertilizers containing only nitrogen (for example, ammonium sulfate) have been used as rooting fertilizers.
しかし最近冷害抵抗性に対しリン酸の効果が確認されて
から窒素−リン酸−加里、窒素−リン酸等の化成肥料、
特に複合高度化成肥料を根付肥として使用することが検
討されている。However, since the effect of phosphoric acid on cold damage resistance has recently been confirmed, chemical fertilizers such as nitrogen-phosphoric acid-potassium, nitrogen-phosphoric acid, etc.
In particular, the use of complex advanced chemical fertilizers as rooting fertilizers is being considered.
この複合高度化成肥料は、窒素とリン酸と加里の合計量

リン安に硫安、塩安、尿素、塩化カリウム等を加えたも
のを造粒機で粒状にして製造されている。This composite advanced chemical fertilizer has a total content of nitrogen, phosphoric acid, and potassium of 30% or more, and is made by ammonizing wet phosphoric acid into a slurry, or by drying it to form ammonium phosphorus and ammonium sulfate. It is manufactured by adding ammonium chloride, urea, potassium chloride, etc. and granulating it using a granulator.

ニールホースの寿命が短かくなる等の不都合が生じる。- Incidentally, with the recent mechanization of agriculture, fertilizers have been spread using machines, but when the above-mentioned compound advanced chemical fertilizer is spread using a backpack-type power spreader for pesticides, for example, , the particle size of conventional compound advanced chemical fertilizer is 1m.
Since the particle size is considerably larger than the particle size of agricultural chemicals, it is difficult to spray uniformly.Furthermore, the vinyl hose used for the spray head of the backpack-type power sprayer is easily damaged, and the life of the vinyl hose is short. Inconveniences such as darkening may occur.

接続し、そして該ホースの吐出口から１ｍ離れた位置に
約６０個の肥料採取用マス（寸法０．５ｘ０．５ｘ０．
１５ｍ）を並べ、然る後背負式動力散布機に本発明の化
成肥料を供給して散布し、各マスの中に入った肥料重量
の合計量を測定して行なった。In the spraying test, a backpack-type power spreader was installed on a platform 0.9m above the ground, a 30m multi-mouth spraying hose was connected to the outlet of the spreader, and a sprayer was placed 1m away from the outlet of the hose. Approximately 60 squares for collecting fertilizer (dimensions 0.5x0.5x0.
15 m) were lined up, the chemical fertilizer of the present invention was supplied to a backpack-type power spreader, and the chemical fertilizer of the present invention was spread.The total weight of the fertilizer contained in each square was measured.

ースを接続し、試験例−１で用いたのと同じ化成肥料を
多口ホースの吐出口から該吐出口が変形するまで繰返し
散布して行なった。The durability test was conducted in the same manner as in Test Example 2, in which a backpack-type power spreader was installed on the table, and a multi-mouth hose was connected to the discharge port of the spreader, and the same method as used in Test Example 1 was conducted. The chemical fertilizer was repeatedly sprayed from the discharge port of a multi-mouthed hose until the discharge port was deformed.
すなわち、図面に示すように多口ホース１の吐出口２か
ら散布される肥料３によって吐出口２が変形して該吐出
口２付近に設けた衝壁４が倒れるまで肥料３の散布を繰
返し行なった。That is, as shown in the drawing, the fertilizer 3 is sprayed repeatedly from the discharge port 2 of the multi-mouth hose 1 until the discharge port 2 is deformed and the barrier wall 4 provided near the discharge port 2 collapses. Ta.
なお比較のために試験例１で用いた比較例３の化成肥料
についても同様の試験を行なった。For comparison, a similar test was also conducted on the chemical fertilizer of Comparative Example 3 used in Test Example 1.
この耐久試験から表−８に示す結果を得た。The results shown in Table 8 were obtained from this durability test.
耐久度は吐出口が変形するまで吐出された肥料の総重量
から求めた。Durability was determined from the total weight of fertilizer discharged until the discharge port was deformed.
上記の測定結果から明らかな如く、本発明の化成肥料は
比較例のものに比して約２．５倍多く散布することがで
きる。As is clear from the above measurement results, the chemical fertilizer of the present invention can be applied approximately 2.5 times more than that of the comparative example.
換言すれば、本発明の化成肥料を使用した場合にはホー
スを傷つけないからそれだけホースの寿命が長くなる。In other words, when the chemical fertilizer of the present invention is used, the hose will not be damaged, so the life of the hose will be extended accordingly.
