摘要:

【目的】研究种衣剂对冬播春小麦品种生育特性和产量的影响。【方法】采用随机区组排列,设8个处理,测定麦小麦品种生育进程、叶面积指数和干物质等措施,分析7种种衣剂包衣后冬播(11月1日)对新春29号出苗率、茎数动态、叶面积指数、光合势、干物质积累、产量等的影响。【结果】3.7%吡唑醚菌酯+7.3%灭菌唑悬浮种衣剂(a)、4.6%氟唑环菌胺+2.2%咯菌腈+2.2%苯醚甲环唑悬浮种衣剂(b)较CK分别提高出苗率19.03百分点、20.70百分点,总茎数峰值分别增加27.38%、23.44%,叶面积指数峰值分别增加62.55%,51.98%,总光合势分别增加87.53%、73.72%;干物质分别增加53.63%、37.59%,产量分别增加54.43%、38.40%。【结论】种衣剂a、b对冬播春小麦是能够提高出苗率,增加成穗数并增产。

Abstract:

【Objective】 To compare the effects of dressing agents on the fertility characteristics and yield of spring wheat varieties sowed in winter. 【Methods】 The influences of seven kinds of coatings on the seedling yield, stem number dynamics, leaf area index and photosynthesis potential, dry matter accumulation, yield, etc. after seven coatings were studied in the field. 【Results】 The results showed that 3.7% pyrazole ether + 7.3% sterilization azole suspended seed coating agent (a), 4.6% flurazolamide + 2.2% flurazolonil + 2.2% diphenyl ether dicyclazole suspended seed coating agent (b), compared with CK, increased the seedling rate by 19.03% and 20.70%, respectively, the total stem peaks increased by 27.38% and 23.44%, respectively, and the peaks of the leaf area index increased by 62.55 percent and 51.98 percent, respectively. The total photosynthetic potential increased by 87.53% and 73.72%, respectively. The dry matter increased by 53.63%t and 37.59%, respectively, and the yield increased by 54.43% and 38.40%, respectively.【Conclusion】 Under this test condition, the coating agent a and b have the effect of protecting seedlings and increasing the yield of winter-sown spring wheat. The main reason for increasing production is to improve the seedling yield and increase the number of ears.

Key words: spring wheat; seed dressing agent; sowing in winter; emergence rate; dry matter; yield
