摘要:
为研究干旱区土壤施用改良剂对作物生长发育的影响,本试验在不同年份以马铃薯、油葵为试验材料,在滴灌条件下施用不同土壤改良剂进行试验。试验均采用单因素随机区组设计,对施用不同改良剂下马铃薯、油葵的生长发育及产量进行了研究。结果表明:不同改良剂对作物的生长发育均有不同程度的促进作用,不同改良剂的促进作用不同。马铃薯的试验中,宁大改良剂II型的效果最好,其处理下的小区产量(1163.05 ± 191.14 kg)最高,对株高和叶面积也有促进作用。油葵的试验中,宁大改良剂I型和宁大改良剂II型施用效果比市售改良剂和生物有机肥的改良效果显著,能显著影响茎粗(宁大改良剂II型33.13 mm和宁大改良剂I型29.82 mm)、干物质质量(宁大改良剂II型1581.398 kg和宁大改良剂I型1472.305 kg)、叶面积指数(宁大改良剂II型6.72和宁大改良剂I型6.18为最适宜),产量结果也以宁大改良剂I型和宁大改良剂II型的最高,宁大改良剂I型(255.57 ± 25.93 kg)产量最高。试验结果说明,施用改良剂对油葵和马铃薯生长、产量都有促进作用,且以宁大改良剂I型和宁大改良剂II型的效果最好。

Abstract: In order to study the effects of soil amendments on the growth and development of crops in arid regions, the experiment was conducted in different years by using different kinds of soil amend-ments. The single factor randomized block design was used to study the growth and yield of potato and oil sunflower under different amendments. The results showed that different modifiers had different effects on the growth and development of crops. In the experiment of potato, type II had the best effect, and the yield (1163.05 ± 191.14 kg) was highest, and the plant height and leaf area were also promoted. In the experiment of oil sunflower, the improvement effect of type I and type II was significantly better than that of the modified agent and bio organic fertilizer, and they can significantly affect the stem diameter (Ningda modifier type II 33.13 mm and Ningda modifier type I 29.82 mm), dry matter (Ningda modifier type II 1581.398 kg and Ningda modifier type I 1472.305 kg), leaf area index (Ningda modifier type II 6.72 and Ningda modifier type I 6.18 was most suitable), and the results also showed that the highest yield was the best type I and II of modified agent, and Ningda modifier type I (255.57 ± 25 .93 kg) was highest. The results showed that the application of amendments had a positive effect on the growth and yield of oil sunflower and potato, and the best effect was found in the type I and the type II modi- fier.
