水稲直播栽培は、イネ種子を直接水田に播く栽培方法であり、育苗や移植作業が不要であるため農作業の省力化を図ることができる等の利点を有する一方、カモやスズメ等の鳥による食害（鳥害）を受け易いという欠点も有している。鳥害による苗立ち率の低下は減収につながるため、鳥害回避策が切望されてきた。従来の鳥害回避策としては、例えば、水管理により鳥害を防止する方法が提案されているが、鳥の種類に応じて管理方法を変更する必要がある（例えば、非特許文献１参照）。 Paddy rice direct sowing cultivation is a cultivation method in which rice seeds are sown directly in paddy fields. It also has the disadvantage of being susceptible to (bird damage). Decreasing the seedling establishment rate due to bird damage leads to a decrease in revenue, so bird damage avoidance measures have been eagerly desired. As a conventional bird damage avoidance measure, for example, a method for preventing bird damage by water management has been proposed, but it is necessary to change the management method according to the type of bird (for example, see Non-Patent Document 1). .

酸化亜鉛３Ｎ５ ５．０ｇ、炭酸カルシウムＧ−１００ ５．０ｇ、クラレポバール ＰＶＡ２２０Ｓ ０．１ｇ及びベントナイト穂高０．２５ｇを混合して本防止剤（２）を得た。
以下の操作は製造例２に記載の方法に準じて行った。本防止剤（１）１０．４ｇに代えて本防止剤（２）１０．３５ｇを添加してイネ種子に付着させた。イネ種子に噴霧した水の全量は２．８ｇであった。次いで、ソルポール５０８０ ０．１ｇを、コーティングした酸化亜鉛の表面に付着させ、乾燥させることにより、酸化亜鉛コーティングイネ種子（３）を得た。
Production Example 3
This inhibitor (2) was obtained by mixing 5.0 g of zinc oxide 3N5, 5.0 g of calcium carbonate G-100, 0.1 g of Kuraray Poval PVA220S and 0.25 g of bentonite ear height.
The following operations were performed according to the method described in Production Example 2. In place of 10.4 g of the present inhibitor (1), 10.35 g of the present inhibitor (2) was added and adhered to rice seeds. The total amount of water sprayed on the rice seeds was 2.8 g. Next, 0.1 g of Solpol 5080 was attached to the surface of the coated zinc oxide and dried to obtain zinc oxide-coated rice seed (3).
製造例４
酸化亜鉛二種 ２．５ｇ、炭酸カルシウムＧ−１００ ７．５ｇ及びアミコールＷ ０．４ｇを混合して本防止剤（３）を得た。
以下の操作は製造例２に記載の方法に準じて行った。本防止剤（１）に代えて本防止剤（３）を添加してイネ種子に付着させた。イネ種子に噴霧した水の全量は２．０ｇであった。次いで、乾燥させることにより、酸化亜鉛コーティングイネ種子（４）を得た。
Production Example 4
This inhibitor (3) was obtained by mixing 2.5 g of zinc oxide (2.5 g), 7.5 g of calcium carbonate G-100 and 0.4 g of amylol W.
The following operations were performed according to the method described in Production Example 2. The present inhibitor (3) was added in place of the present inhibitor (1) and adhered to rice seeds. The total amount of water sprayed on the rice seeds was 2.0 g. Next, by drying, zinc oxide-coated rice seeds (4) were obtained.
次に、試験例を示す。 Next, test examples are shown.
試験例１
プラスチックシャーレに土壌約３０ｇを入れて、水で湿らせた後、酸化亜鉛コーティングイネ種子５０粒を土壌表面に播いた。該プラスチックシャーレを屋外に静置し、タイムラプスカメラで撮影することにより該プラスチックシャーレの様子を観察するとともに、播種１日後に残存するイネ種子を計数し、以下の式より残存率を算出した。
残存率（％）＝播種１日後に残存するイネ種子数／５０×１００
結果を表１に示す。なお、表１においてイネ種子（対照）とは、何もコーティングされていないイネ種子を指し、該種子はスズメ等の鳥により食害されたため、残存率が０％であった。
Test example 1
About 30 g of soil was put in a plastic petri dish and moistened with water, and 50 zinc oxide-coated rice seeds were sown on the soil surface. The plastic petri dish was left outdoors and photographed with a time lapse camera to observe the state of the plastic petri dish, and the rice seeds remaining one day after sowing were counted, and the survival rate was calculated from the following formula.
Residual rate (%) = number of rice seeds remaining one day after sowing / 50 × 100
The results are shown in Table 1. In Table 1, rice seed (control) refers to rice seed that is not coated with anything, and the seed was damaged by birds such as sparrows, so the residual rate was 0%.
