| 摘 要： | 该试验对宁夏中部干旱带旱地马铃薯施用土壤保水剂的效应进行了研究.结果表明：ZB保水剂在旱地马铃薯上施用具有一定的保水蓄水、增产作用,可有效提高20～60cm土壤水分含量,对40～60 cm土壤含水量的影响更加显著;保水剂施用要与地膜覆盖相结合,有助于进一步发挥保水剂蓄水增产、提高水分利用效率的作用.在覆膜模式下,保水剂适宜施用量为4 g/m2.

| Abstract: | Effect of ZB absorbent polymer on dryland potato yield components and wmer use efficiency was studied. It turned out that ZB absorbent polymer could increase the lasting drought-resistant ability of soil and potato yield which could improve the moisture content of 20-60 cm soil layer soil. ZB absorbent polymer could significantly increase the moisture content of 40-60 cm soil layer soil. The soil water content from jointing stage to harvest was lower than the contrast. Absorbent polymer combined with plastic film mulching can help to improve the moisture content and potato yield. 4 g/m2 absorbent polymer was the best treatment with plastic film. |
