摘  要:
【目的】研究不同播种深度下大小苗对棉花产量、品质的影响,为棉花适宜播种深度提供理论依据。【方法】设置5种播种深度,单因素随机区组设计,通过田间试验,研究棉花产量、品质的特征。【结果】播深为2 cm时,大苗产量为425.72 kg/667 m~2,小苗产量为8.46 kg/667 m~2,整个小区产量最高,为482.16 kg/667m~2,且纤维品质较好;当播深超过2 cm时,随着播种深度的加深,棉花的产量呈现降低的趋势。播深为4 cm时,大苗株数为1 777株/667 m~2,小苗株数为0株/667 m~2,大苗产量为120.03 kg/667 m~2,小苗无产量,整个小区产量最低,与CK差异显著。在品质方面,大苗棉花在上半部均长、马克隆值、成熟度、整齐度和反射率上差异显著,小苗棉花在上半部均长和成熟度上差异显著,而整个小区棉花只在整齐度存在差异,其余各品质特征差异不显著。【结论】播深是影响棉花产量的重要因素,适宜播种深度为2 cm,覆土1 cm,且播深不宜超过3cm,播深为2 cm时棉花综合品质最好。

摘  要:
【Objective】To reveal the effects of different sizes of seedlings on the yield and quality of cotton under different sowing depths and provide theoretical basis for the sowing depth.【Method】Setting 5 sowing depth,single factor randomized block design,the field experiment was conducted to study the characteristics of cotton yield and quality characteristics.【Result】When sowing depth was 2 cm,seedlings yield was425. 72 kg/667 m~2,seedling production was 8. 46 kg/667 m~2,the entire district got the highest yield of482. 16 kg/667 m~2,and good fiber quality; When the sowing depth was more than 2 cm,. with the deepening of sowing depth,the yield of cotton showed a decreasing trend. When the sowing depth was 4cm,the large number of seedling was the 1,777/667 m~2,the small number of seedlings was 0/667 m~2,the large seedlings yield was 120. 03 kg/667 m~2,the small seedling had no yield. The entire district produced the lowest yield,significant difference with CK. In terms of quality,cotton seedlings were long in the upper half,the micronaire,maturity,uniformity and reflectivity were significantly different. The cotton seedlings in the upper half of the small ones were long and there was great difference in maturity. And in the whole area of cotton,there was only difference in the uniformity. The rest of the quality characteristics were not significant.The sowing depth of 2 cm integrated best quality cotton.【Conclusion】Sowing depth is an important factor affecting cotton yield,the suitable planting depth is 2 cm,cased with 1cm soil,and sowing depth should not exceed 3 cm.
