摘要
利用大田试验的方法研究了KD—1型抗旱保水剂在苹果树上的使用效应。结果表明,每棵果树使用抗旱保水剂25～100g,可使土壤含水量平均增加2.01%～2.25%,土壤容重降低0.093g/cm3,大于0.25mm的团粒结构增加10.28%,果树新梢长度和粗度分别增加3.66cm和0.04cm,单果重平均增加23g,差异明显。但使用保水剂对土壤酸碱度和果实含糖量的影响作用不明显。
The domino effects of droughtresistant and waterabsorbent polymer applied on apple trees were studied by field test methods. The results showed that by used 25～100 g/plant droughtresistant and waterabsorbent polymer, the soil water content increased from 2.01% to 2.25% on average, and the soil bulk density decreased 0.093 g/cm3, and the soil granular structure over 0.25mm increased 10.28%; the length and the thick of new tips increased 3.66 cm and 0.04 cm respectively. The weight of single apples increased 23 g on average, and the differences were notable. While the effects on soil pH and sugar content of fruit were not evidence by applying droughtresistant and waterabsorbent polymer.
