*癸萌は、 作物の作付後であ っ ても、 残留薬品ゃ土壤 の生態系の破壊に よ る弊害を生 じ させる こ と な く 手軽に 線虫類の ¾除ができ る よ う にする こ と を 目 的 と する も の で あ る * Kishimoe can remove nematodes easily even after crop cultivation without causing residual chemicals and harm caused by destruction of the soil ecosystem. The purpose is to do
上記 目 的は、 少な く と も一対の電気端子を土壌中に位 置 させ、 こ の対を なす電気端子間に高電圧パル ス を印加 する 線虫類 の ¾除方法 （以下 「第 1 発明』 と い う） に よ っ て達成される も のである。 また、 上記 目 的は、 対を なす一方の電気端子 を土壤中に位置させ、 他方の電気端 子を作物 自体に接蝕 させ、 こ の両電気端子間に高電圧パ jレ ス を 印加する線虫類の ¾除方法 （以下 「第 2 発明」 と い う ) に よ つ て も 達成ざれる も のであ る The above object is achieved by placing at least one pair of electrical terminals in soil and applying a high-voltage pulse between the pair of electrical terminals to remove nematodes (hereinafter referred to as “the first invention”). In addition, the above-mentioned purpose is to place one pair of electric terminals in the soil, and to make the other electric terminal infest the crop itself, This cannot be achieved even by the nematode control method (hereinafter referred to as the "second invention") in which a high-voltage pulse is applied between these two electrical terminals.
第 2 癸明は、 作物の作付後にのみ用い られる も の で あ る が、 第 1 発明 は作物の作付後のみな ら ず、 作付前に あ らか じ め線虫類を土壌か ら翳除 してお く の に も 用 い る こ と がで き る も の であ る 。 即ち、 第 1 発明 に おい て、 作物 の作付後に そ の根を 間 に置いて対をなす電気端子を位置 させれば根に窨生 し た線虫類を も駆除で き 、 ま た作物の 作付前 におい ては、 対を なす電気端子間の土壌中の線虫 類を駆除 し て そ の後 に作付される作物への線虫類の寄生 を予防で き る 。 The second kishi is used only after crop cultivation, but in the first invention, nematodes are shaded from the soil in advance not only after crop cultivation but before crop cultivation.

To a lesser extent, they also have very little negative effect on plants. The reason why nematodes can be removed by this shock current is that when a shock current flows through the nematode's body surface, the nematodes are removed. Even with a relatively small current due to shock, it can cause nematode cell membrane damage and cytoplasmic destruction, and stop reactivation that has impaired its activity. It is thought to be something . Since the nematodes are controlled by such a shock current, there is no need to worry about the adverse effects of residual chemicals. Since the activities of microorganisms that have relatively low drag on the soil are maintained, there is no intention to seriously damage the soil ecosystem.

'' Is enough. The pulse voltage is applied several times to several tens of times at a rate of once to several times every 1 to 2 seconds so that the positive and negative pulses alternate. It is best to repeat it. The voltage is too low for 3-click霄流is rather Ku to obtain a sufficient disinfection effect is insufficient, Ru a danger of causing crop failures and excessive current flow and too high voltage. In addition, even if the pulse voltage is applied continuously for a long time, the power consumption is increased but the control effect is not improved so much, and conversely, there is a possibility that the crop is adversely affected. In particular镍虫class given廷展direction to the potential is the most affected in the period that the One I pressure 'of, nematodes were Tsu cry to decrease death in one of the three click current dynamic rather than to the lower of the potential Since this has been confirmed, it is preferable to apply the voltage several times. Takishiaki has the advantage of being able to get rid of mogras and earthworms, if not killed. As a power source for generating high-voltage pulses, for example, An appropriate one may be selected according to the location, such as a household power supply, a generator or a battery of a car.

B was repeated 10 times. Thereafter, when the plants were grown while repeating the same voltage application every 10 days, a good harvest was obtained without any crop failure.
実施例 2 Example 2
第 5 図 に示 され る よ う に、 棒状の電気端子 を 土壤中 に 埋設 し 、 他方の電気端子を作物に接触 さ せて S置 し た。 対彔作用は ドマ ト で、 土壌中に埋設 した電気端子は、 こ の ト マ ト の 作付位置 よ り 70cmの 位 置 で深 さ 20 c πで埋設 し 、 ト マ ト に接触 させた電気端子は、 土壤表面 よ り 2 0 c a 上方の幹部に卷き付けた。 あ らか じめネ コ ブ線虫を土壤 に加え ておき 、 苗を定植後実施例 i と同様に高電圧パル ス を両電気端子間に印加 した と ころ、 実施例 1 と 同様 に 良好な収穫が得 られた。 ， As shown in Fig. 5, a rod-shaped electrical terminal was buried in the soil, and the other electrical terminal was placed in contact with the crop and placed S. The interaction is domat.Electrical terminals buried in the soil are buried at a depth of 20 cπ at a position 70 cm from the cropping position of this tomato. Then, the electrical terminal that was in contact with the tomato was wound on the trunk 20 ca above the soil surface. A cat worm was added to the soil in advance, and after the seedlings were planted, a high-voltage pulse was applied between both electric terminals as in Example i. The harvest was obtained. ,
