中文摘要	为了提高干旱半干旱地区马铃薯的出苗率和产量,采用田间试验方法进行了"莯润"抗旱营养缓释剂穴施、浸种对马铃薯生长和产量的影响试验,研究了缓释剂固态水施入土壤对马铃薯块茎大小的影响。结果表明,"莯润"抗旱营养缓释剂穴施、浸种极显著地提高了马铃薯的出苗率(p<0.01),都比对照提高了76.2%;马铃薯的植株高度比对照增加21.8%~44.5%,均达到极显著水平(p<0.01),生育前期根冠比偏低比较有利,可以为后期马铃薯块茎的生长和物质的积累提供有利条件;施用缓释剂使马铃薯产量增加12.4%~16.7%,但没达到显著水平(p>0.05)。"莯润"抗旱营养缓释剂固态水施入土壤,减少了直径小的马铃薯的数量,增加了直径大者的数量,使得马铃薯块茎的平均直径增大,商品性增加。"莯润"缓释剂提高了马铃薯的出苗率和产量,固态水的使用提高了水分利用率和马铃薯的商品性。
英文摘要	In order to improve the seed germination rate and yield of potato in arid and semi-arid area,a field plot experiment was performed to find which is optimal for hole-use and seed soaking applications of the Murun drought resistance and nutrition slow-release agent(MDRNSA),and analyze the effects of sustained release agent(SRA)application on the growth and yield of potato.The effect of SRA solid water application on the potato tuber size was also investigated.Results showed that both the hole-use and seed soaking applications improved potato seed germination rate very significantly(p<0.01),with an increment of 76.2%in contrast to control.The height of potato plant was promoted by 21.8%~44.5% more than that in control and the difference was significant between the two applications(p<0.01).The lower ratio of root to shoot in the early stage of growth provided a favorable condition for the growth of potato tuber and the accumulation of substances in the late stage of growth.The potato yield was promoted by 12.4%~16.7% more than that in CK,but the increment was not significant(p>0.05).With the way of solidification,the number of small potato decreased,the number of big potato increased,the average diameter of potato tuber increased, and the marketability of potato rose.It follows from the research that SRA improved the yield and seed germination rate of potato and the use of solid water increased water use efficiency and the marketability of potato.
