摘要
该文通过正交试验,探讨了在有限灌水条件下黄腐酸类抗旱剂FA旱地龙对果树的生长发育、保墒能力、果实品质及产量的影响。研究结果表明:果树施用FA旱地龙后,有抗旱增产效果,增产幅度可达4.88%～7.32%,平均单果质量增加4.2%～8.4%,并且使果实品质得到改善;与充分灌溉条件相比,水分利用效率也有所提高,每hm2节约灌溉水量487.5m3。同时,该文还在分析本地区各降水年型水分盈亏特点的基础上,探讨了不同降水年型下FA旱地龙的最佳喷施次数和喷施时间。
The orthogonal experiment was conducted to study the application of FA Handilong, a kind of drought-resistant agent for fruit tree. Its effect on the growth, capability against drought, fruit quality and yields of fruit were investigated. The results show: FA Handilong, could increase its drought-resistant potential of the fruit tree and its yield increased by 4.88%~7.32%; The economic benefit increased by 15654.00~23559.00 yuan per hectare. The average fruit weight could be increased using FA Handilong by 4.2%~8.4%. The fruit quality was also improved. Compared with the condition of full irrigation, the water use efficiency was also improved, and the irrigative water was saved by 487.5 m^3 per hectare. The best frequency and time of the application of FA Handilong were discussed.
