This paper reviews the effects of al on photosynthesis, photoprotective systems, water use efficiency ( wue ), water content, carbohydrate content, mineral nutrition, organic acids, and nitrogen metabolism in plant shoot, and also the mechanisms of al detoxification ( chelation of al with small organic compounds, and isolating al in the some parts, which are insensitive to al, such as vacuoles or epidermal cells ) by al accumulators
為此，本文綜述了鋁對植物地上部光合作用、光保護系統、水分利用效率、含水量、碳水化合物含量、礦質營養、有機酸和氮代謝的影響，並對富鋁植物的解鋁毒機制（鋁與小分子有機酸螯合和把鋁隔離在對鋁不敏感的表皮細胞和液泡內）進行了綜述。 -
After the acet is vaporized, the active substance in water is gotten. and which is vaporized at low temperature. then the crude active substance is purified by column chromatography on sephadex g - 75. after a series of purifications again, we could get some white powder at last. though the active substance is diluted to50 g / ml, the activity is still checkeded - up through phyto phtnora casicileon. the purified active substance is insensitive to heat, resistant to chloroform 、 ethanol and the orhers. in addition, the active substance is sensitive to high ph ( 10 ~ 14 ), but it is not sensitive to low ph ( 1 ~ 5 ). furthermre, when the ph is made to low again, the activity of it ' s comes back
用蒸餾水對菌體稀釋；加入適量吸附樹脂在150rpm 、 28下振蕩吸附4h ， 80 %的丙酮解吸，過濾解吸液得到活性物質的澄清溶液，旋轉蒸發儀旋轉蒸發去處丙酮，經sephadexg - 75分子篩層析得單一活性峰，收集峰值部分樣品液經冷凍乾燥得到淡褐色粉末，該活性物質用丙酮充分洗滌、甲醇-乙醚重結晶獲得略帶微黃的白色粉末，該活性物質50 g / ml仍可對蘇雲金芽孢桿菌hd - 1產生明顯的抑制作用。 -
As a result of researches, several water indexes were brought up from different methods, such as soil moisture content and air relative humidity, which were most commonly used in the past irrigation control system. for crop water stress, however, those are all insensitive and indirect indexes that represent the environmental states of crops
在已建立的灌溉自動控制系統中，土壤含水量或大氣相對濕度是最常見的控制農作物灌溉的指標，但對作物缺水而言，這些都是反映作物生長環境的間接指標，對反映作物的缺水比較遲鈍、滯后。
