机械耕作对新植甘蔗生长与产量的影响

Effects of Mechanical Tillage Patterns on Growth and Yield of New Planting Sugarcane

从高产角度出发,探讨3种耕作方式下甘蔗生长与产量差异。结果表明,深松犁松土深45 cm+旋耕机碎土深25 cm处理的出苗历时明显短于深松犁松土深45 cm+四铧犁翻土深40 cm+圆盘耙碎土深30 cm处理和深松犁松土深45 cm+圆盘耙碎土深30 cm处理;深松犁松土深45 cm+旋耕机碎土深25 cm处理的株高生长优势明显;蔗茎产量和蔗糖产量以深松犁松土深45 cm+旋耕机碎土深25 cm处理的最高,比其他处理分别增加25.05%~26.22%和24.43%~25.38%。因此,深松犁松土深45 cm+旋耕机碎土深25 cm处理的方式较好。

The growth and yield of sugarcane under three mechanical tillage patterns was studied for high-yield cultivation. The results showed that the emergence duration of subsoiling plow loosen soil depth 45 cm +rotary tiller broken soil depth 25 cm treatment was significantly less than that of subsoiling plow loosen soil depth 45 cm +four-share plow turn over soil depth 40 cm + disc harrow broken soil depth 30 cm and subsoiling plow loosen soil depth 45 cm +disc harrow broken soil depth 30 cm treatment. The plant height growth of subsoiling plow loosen soil depth 45 cm +rotary tiller broken soil depth 25 cm treatment had obvious superiority. The cane yield and sucrose yield of subsoiling plow loosen soil depth 45 cm +rotary tiller broken soil depth 25 cm treatment increased by 25.05%-26.22% and 24.43%-25.38% compared with other treatments. Therefore, treatment of subsoiling plow loosen soil depth 45 cm +rotary tiller broken soil depth 25 cm was a better tillage method.
