中文拼音 [jīngdiǎnbìng]
莖點病
英文
phoma disease-
In recent years, the water - saving and control irrigation technique of rice has diverted from plot experimental and demonstration to lare scale. and has got remarkable economic and social benefits. amed at the characteristics of this irrigation area, optimal selection for water - saving techniques of rice, deciding the amout of leaching water and irrigation modles, investigating the adaptability of the water - saving and control irrigation technique in saline land. studying the increase in production mechanism of the technique are important to extend the technique, to better and develop saline land as well as slick spots. according to the results of field experiments, optimization study was conducted on the water - saving irrigation technique of rice in saline land, the effects of different water - saving irrigation techniques on the physiological indexes and yield of rice were systematically analyzed. by using mutiplepurpose fuzzy optimization method, better. water - saving irrigation technique was selector out, that is. the control irrigation technique in rice. the mechanism of it was analyzed from the aspect of the physiological and ecological saving water of rice to provide the implemental process and technical point ; throgh the quantitive analysis and comparision on control irrigation and control class ( flood irrigation ), high production and quality mechanism of the technique was analyzed in terms of physiology indexes of rice, the variation of soil moisture, the pest resistance and the lodge resistance, the change of soil temperature in paddy fields. the yield constitutive factors, the quality of rice and so on. in saline land. control irrigation and intermittent leaching modles were adopted to validate the adaptability of the technique in irrigation of rice in saline land, to analyze rice ' s physiological - ecological indexes and the change of soil salt content under the conditions of control irrigation leaching of rice and and to provide control irrigation and combined modle of intermittent leaching to adapt to different conditions
本文從試驗及試驗資料入手，取得以下主要成果和結論：對鹽堿地水稻節水灌溉技術進行優化研究，系統地分析了不同節水灌溉技術對水稻生理指標及產量的影響，採用了多目標模糊優化的方法，對灌水技術進行綜合評判，優選了節水灌溉技術，論證該地區宜採用水稻控制灌溉技術；闡述控灌技術通過調節和控制水稻的需水規律，降低水稻高產情況下的無效水量消耗，從水稻生理、生態節水兩方面分析了控灌技術節水機理，針對性地總結出水稻各生育期實施節水控灌技術的步驟及技術要點；通過控灌與淹灌的定量對照比較，從根系、莖蘗、冠層葉片及綠葉動態到株高，土壤水分變化，抗病蟲害、抗倒伏能力，稻田土溫變化，產量構成因素及稻米品質等諸多方面進行動態比較，分析控灌技術高產優質機理；在鹽堿稻地採用控制灌溉+間歇淋洗模式，跟蹤測試田間水鹽變化狀況，驗證控制灌溉技術在鹽堿地區水稻灌溉中應用的適應性，通過分析水稻控制灌溉淋洗條件下水稻生理生態指標，提出優化控制灌溉+間歇淋洗組合模式，為進一步在高礦化度地區試驗水稻控灌技術奠定基礎。Banana seedlings inoculated with fusarium oxysporum f. sp. cubense race 4 appeared some symptoms, such as yellow leaves, browning corm tissue ( occured in the earlier period ), wilting leaves, browning corm and pesudostem tissue, blacking roots ( occured in the middle period ), and wilting, dying plants ( occured in the latter period )
摘要用枯萎病菌4號生理小種接種香蕉苗后，觀察發現：香蕉苗在發病初期出現了黃葉、球莖組織變褐癥狀；發病中期出現了葉片萎蔫、球莖組織變褐、假莖可見斑點狀或線條狀褐色病變、根變黑褐癥狀；發病後期出現了植株萎蔫、枯死等癥狀。Foliage usually dark green ( or sometimes faded ) with dark brown or black necrotic spotting along major leaflet veins often appearing first on under surfaces and also along petiole ; profuse black spotting an sometimes black streaks along stems ) ( “ stem streak necrosis ” )
馬鈴薯錳中毒：葉片通常深綠（有時褪色） ，深褐色或黑色壞死斑點首先出現在表面內沿著主葉脈一直到葉柄，大量黑色斑點有時沿著莖連成一條黑色條紋（ 「莖條紋病」 ） 。
