【摘要】 通过室内与田间试验,研究了保水剂对土壤和猕猴桃产量的影响。试验表明:土壤中保水剂含量在0.01%～0.05%范围内,土壤团粒结构增加较为明显,土面蒸发明显降低,pH值有降低的趋势(0.1～0.2),速效磷含量有所提高;每株施40g保水剂为最佳经济使用量;保水剂使猕猴桃的根冠比趋于合理,具有明显提高商品果之效应;配合微肥施用可减缓黄叶病的发病程度,提高树体抗性,改善果实品质。更多还原

【Abstract】 The indoor and field experiments have been carried out to discover the effect of aquasorb on soil and yield of Actinidia. According to the experimental results, when content of the polymer in soil was in range of 0.01%～0.05%, soil aggregates was increased markedly, evaporation of soil moisture was decreased, the pH value tended to be lowered, and the content of rapidlyavailable P was raised. The results showed that the optimal application rate of aquasorb was 40 g/plant. Aquasorb was effective to have a reasonable C/R ratio and to improve marketable fruit of Actindia. The combining application of aquasorb and trace fertilizer was beneficial to alleviate the occurrence of chlorotic disorder, to strengthen the resistance of trees and to improve the quality of fruit.更多还原
