摘要
该文通过对保水剂在苹果灌溉上的试验研究,分析了保水剂对苹果园灌溉的影响。试验中采用中子仪观测土壤水分的动态变化,通过对不同用量保水剂小区的土壤水分观测,结合果树土壤水分灌溉底线来指导灌溉。结果表明:施用保水剂后水分利用效率提高,施用量200 g/棵是本试验的最优水平,每公顷节水900 m3,同时对保水剂下的果树灌溉制度进行了研究,提出了不同降雨年型的灌溉制度。
Effects of super absorbent polymers on apple irrigation were analyzed. By observing the dynamic change of soil moisture with neutron moisture meter（CNC503DR）, the irrigation was conducted combined the soil moisture with different dosages of super absorbent polymers, and the irrigation base line of soil moisture. Results show that the water use efficiency is improved, the dosages of 200g per tree is the best level in the experiment, and the irrigative water saved by 900 m^3/hm^2. Fruit tree irrigation schedule with super absorbent polymers was analyzed, and the irrigation schedule in different rainfall years was put forward.
