摘要
为促进甘蔗(Saccharum officinarum L.)高效生产,设置深松、深翻及旋耕3种机械耕作方式,分析甘蔗干物质、氮、磷及钾的积累与分配。结果表明,两季甘蔗茎干物质积累量及干物质总量均表现为深松>深翻>旋耕,其中深松与旋耕的差异达显著水平;与其他耕作方式比较,深松的氮、磷及钾积累总量在新植蔗中分别增加6.41%~16.45%、6.38%~26.02%、7.77%~20.92%,在宿根蔗中分别增加5.23%~19.51%、6.92%~19.63%、4.23%~10.40%;深翻的两季甘蔗氮、磷及钾积累总量均高于旋耕,干物质及养分在根中的分配存在显著差异。可见,深松的甘蔗生物产量与养分吸收量较高。
In order to promote efficient sugarcane production,the accumulation and distribution of dry matter,nitrogen,phosphorus and potassium in sugarcane were studied for high-yield cultivation by subsoiling,deep ploughing and rotary tillage.The results showed that,the dry matter accumulation of stake and total dry matter accumulation in two crops were as follows subsoiling>deep ploughing>rotary tillage,and there were significant differences between subsoiling and rotary tillage.The total accumulation of nitro⁃gen,phosphorus and potassium in plant cane under subsoiling increased by 6.41%~16.45%,6.38%~26.02%and 7.77%~20.92%,re⁃spectively compared with other tillage patterns,and increased by 5.23%~19.51%,6.92%~19.63%and 4.23%~10.40%in the first ra⁃toon,respectively.The total accumulation of nitrogen,phosphorus and potassium in two crops under deep ploughing was higher than that under rotary tillage.There were significant differences in the distribution of dry matter and nutrients in roots.Therefore,the bio⁃mass and nutrient uptake of sugarcane under subsoiling were higher.
