摘要
通过两年来对高分子吸水树脂在果树生长上的试验研究,分析了其与黄腐酸类产品配合施用情况下,对土壤墒情、果实生长、果实产量和叶片光合作用的影响。结果表明,施用高分子吸水树脂可提高土壤墒情、加速果实生长、提高果实产量,同时对叶片光合作用也有提高作用。平均年增产2957～3766kg·ha-1,年均增加利润3417～4394元/ha。
The experiments on growth of fruit tree by using super absorbent polymers were conducted in two years and its effects on soil moisture, fruit growth, fruit yield and photosynthesis under the condition of using it together with fulvic acid were analyzed. The result showed that the use of super absorbent polymers increased soil moisture, accelerated fruit growth, increased fruit yield, and improved photosynthesis of the leaves. The results showed that yield increased by 2 957-3 766 kg per hectare and the economic benefit increased by 3 417-4 394 yuan per hectare.
