申, 宝明; 佐藤, 禎稔; 岸本, 正; 谷, 昌幸; 仙北谷, 康; 加藤, 拓; 林, 芙俊; SHEN, Baoming; SATOW, Tadatoshi; KISHIMOTO, Tadashi; TANI, Masayuki; SENBOKUYA, Yasushi; KATO, Taku; HAYASHI, Futoshi.
マニュアスプレッダによる堆肥の散布精度の現状を把握することを目的とし,横軸ピータ型,縦軸ビータ型,左側方散布型の3機種を対象として堆肥の散布量分布および 堆肥散布精度の調査を行った。各機種の散布量分布は,いずれも山型の形状を示しており,横軸ビータ型,縦軸ピータ型では,マニュアスプレッダの中心から左右1m以内に,それぞれ全体の76%,40%が散布され,左側方散布型は左側3-5mの範囲に全体の71%が集中して散布された。最大散布畳は横軸ビータ型が2.3t/l0a,縦軸ビータ型が6.5t/10a,左側方散布型が10.3t/l0aとなり,重複散布しても規定散布量である2t/l0aが望めない結果となった。また,圃場全体の堆肥散布量は各機種で0.2-3.4t/lOa,2.4-22. 8t/l0a,0.6-5.0t/10aであり, 堆肥の性状によって散布むらが大きくなることが判明した。The purpose of this study was to investigate the present situation of compost spreading with manure spreaders in Tokachi region. Therefore,three different types of manure spreaders: rear horizontal beater type(A),vertical beater type (B) and side discharge type (C),were used to determine the application pattern and accuracy of compost spreading. Application pattern of each...

昆虫寄生性Lecanicillium muscarium融合株2aF43およびオンシツツヤコバチの併用によるオンシツコナジラミ防除効果の評価 OAK
風間, 諒太; 谷, 昌幸; 小池, 正徳; 相内, 大吾; KAZAMA, RYOTA; TANI, MASAYUKI; KOIKE, MASANORI; AIUCHI, DAIGO.
This study aims to evaluate the control efficacy of greenhouse whitefly by co-application of entomopathogenic fungus Lecanicillium muscarium hybrid strain 2aF43 and greenhouse whitefly parasitoid Encarsia formosa, and to reveal the interaction between both natural enemies. Although, the emergence rate of adult greenhouse whitefly reached 93.2% in control plot, co-application plot indicated significantly lower emergence rate (4.2%). Co-application plot showed higher fungal infection compared with singularly L. muscarium inoculated plot. Parasitization rate in singularly E. formosa released plot reached 81.7% and emergence rate of parasitoid was 72.1%, but lower parasitization and emergence rate of parasitoid (13.2% and 2.0% respectively) were detected on...

長期有機物連用圃場における黒ボク土の荷電特性 OAK
八木, 哲生; 谷, 昌幸; Yagi, Tetsuo; Tani, Masayuki.
農耕地土壌への有機物施用は,化学的効果として陽イオン交換容量(CEC)の増加などが考えられているが,詳細な荷電特性に関するデータは見られない.また,慣行法であるショーレンベルが一法によるCEC測定は,変異荷電成分を多量に含む土壌においては適切でないと考えられる.本研究では,25年間にわたって堆肥や作物残渣などの有機物を連用した黒ボク土のCECおよび陰イオン交換容量(AEC)を繰り返し平衡法により測定し,荷電特性に対する有機物の連用効果について明らかにすることを目的とした.CECは,有機物施用区が化学肥料区よりも若干高かった.その差はきわめて多量の堆肥(30 Mg ha^<-1>)を毎年連用した区において,pH5.5前後で約20%,pH6.5前後で約10%であった.現実的な堆肥の施用量(15Mg ha^<-1>...

十勝地域の未耕地土壌および農耕地土壌におけるリン酸の垂直分布と蓄積量 OAK
谷, 昌幸; 溝田, 千尋; 八木, 哲生; 加藤, 拓; 小池, 正徳; TANI, Masayuki; MIZOTA, Chihiro; YAGl, Tetsuo; KATO, Taku; KOIKE, Masanori.
本研究では,十勝地域の農耕地,とくに普通畑土壌にお ける肥培管理などが土壌へのリン酸蓄積量とその形態に及ぼす影響を明らかにすることを目的とした.畑地およひ隣接する未耕地において土壌断面調査と試料採取を行い,土壌中の全リン酸含量および各種形態別リン酸含量の垂直分布を調べたさらに,仮比重および未耕地と農耕地における土壌の層厚差を考慮し正味のリン酸蓄積量を調べた. 1)淡色黒ボク土,厚層黒ポク土,および普通褐色低地 土のいずれの農耕地土壌においても,施肥などに由来する余剰リン酸は耕起の影響を受けた表層30~40cm までの 作土層に蓄積し,物理的に撹拌および混和されることにより作土層全体に比較的均一に分布した. 2)未耕地土壌との垂直分布の比較から,黒ボク土では 余剰リン酸が下層へ溶脱せず作土層にのみ蓄積し,褐色低地土では一部が下層へ溶脱していると考えられた. 3) 農耕地における正味のリン酸蓄積量は,黒ボク土で 著しく多く,年平均130kgha-1以上であった. 大部分は,フッ化物イオンの配位子交換能により抽出され,活性アルミニウムなどに特異吸着されていると考えられた褐色低地土では蓄積量が少なく,弱酸可溶のリン酸水素カルシウムや,弱い配位子交換反応で抽出可能な非品質リン酸アルミニウムなどの沈殿として蓄積していると考えられた.Heavy application of phosphate fertilizer and subsequent phosphate accumulation in arable soilsï¼ especially Andosolsï¼ are critical issues for sustainable agriculture in ]apan. The effects of...

ダイズシストセンチュウに対するVerticillium lecanii プロトプラスト融合株の微生物防除資材としての可能性:プロトプラスト融合は植物寄生性線虫の生物的防除において有用な手法と成り得るか? OAK

Verticillium lecanii is a potentially useful biological control agent (BCA) for soybean cyst nematode (SCN), Heterodera glycines. The objective of this study was to screen hybrid strains of V. lecanii, derived from protoplast fusion, for effective control agents of SCN, and to investigate whether the protoplast fusion technique is an effective tool for development of nematode control agents. Three parental strains (Vertalec®, Mycotal®, and B-2) and their 162 hybrid strains were screened in greenhouse pot tests. Some of these hybrid strains suppressed damage on soybean plants and reduced the density of SCN in the soil. In particular, one hybrid strain, AaF42, was observed to reduce the nematode egg density by 93.2% as compared with the control. Furthermore,...

Variation in growth at different temperatures and production and size of conidia in hybrid strains of Verticillium lecanii (Lecanicillium spp.) (Deuteromycotina: Hyphomycetes) OAK
AIUCHI, Daigo; BABA, Yukiko; INAMI, Keigo; SHINYA, Ryoji; TANI, Masayuki; KOIKE, Masanori; 相内, 大吾; 谷, 昌幸; 小池, 正徳.
In a previous study, we confirmed alterations in several fungal traits in hybrid strains of Verticillium lecanii generated via protoplast fusion. In the present study, we surveyed radial colony growth in different temperature regimes as well as conidia productivity and conidia size of hybrid strains of V. lecanii to elucidate the various primary fungal properties of these strains and to determine the correlation between these properties and virulence to insect pests. Minimum temperature thresholds for all tested strains (except Vertalec®) were below 5°C. Optimal temperatures for colony growth were 20–25°C. Colony growth at high temperature was good or poor depending on the genotype. Temperature and strain significantly affected colony growth. Conidial...
