Description

本発明は、イネ種子鳥害防止剤及びイネ種子鳥害防止方法に関する。   The present invention relates to a rice seed bird damage prevention agent and a rice seed bird damage prevention method.

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). .

Production Example 1
First, a simple seed coating machine capable of coating when a small amount of rice seed was used was prepared. As shown in FIG. 1, a polyethylene cup 2 having a capacity of 500 mL is attached to the tip of the shaft 1 and inserted into the drive shaft of a stirrer 3 (three-one motor, manufactured by Shinto Kagaku Co., Ltd.), so that the elevation angle is 45 degrees. Thus, the simple seed coating machine was produced by attaching the stirrer 3 to the stand 4 in an oblique manner.
0.22 g of Superflex 500M and 0.19 g of water were mixed to obtain 0.41 g of Superflex 500M water dilution.
About 100 mL of water was put into a 200 mL capacity polyethylene cup, and 20 g of dried rice seeds was added thereto and soaked for 10 minutes. Thereafter, the rice seeds were taken out from the water, and after removing excessive water on the surface, they were put into a polyethylene cup 2 attached to the produced simple seed coating machine. A simple seed coating machine is operated in the range of the rotation speed of the stirrer 3 within a range of 130 to 140 rpm to bring rice seeds into a rolling state, and 0.41 g of Superflex 500M water dilution and 1.0 g of zinc oxide are added to the rice seeds. Thus, zinc oxide was attached to rice seeds. Next, the rolling state of the rice seeds was maintained with the simple seed coating machine being operated, and 0.1 g of Solpol 5080 was added to adhere to the surface of the coated zinc oxide. The rice seeds taken out from the simple seed coating machine were spread so as not to overlap the stainless steel vat and dried overnight to obtain zinc oxide-coated rice seeds (1).

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

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%.
