对三个葡萄品种(VutisViniferal)进行喷灌,测定它们是否通过叶片吸收过量的钠盐及氯离子而中毒。叶内钠和钙的浓度都随着喷灌时间的增加而呈直线增大,在喷水54小时后叶内二种离子都已接近已知的忍耐量。三种不同盐份(氯化钠,氯化钙和硫酸钠)中的供试离子,对钠和氯离子的累积没有影响。
Three grape varieties (Vutis Viniferal) were sprinkled to determine if they were poisoned by the leaves absorbing excess sodium and chloride ions. The concentration of sodium and calcium in leaves both increased linearly with the increase of sprinkling time, and the two kinds of ions in leaves were close to the known endurance after 54 hours of sprinkling. The test ions in the three different salts (sodium chloride, calcium chloride and sodium sulfate) have no effect on the accumulation of sodium and chloride ions.
