不同种植密度对留茬膜侧马铃薯产量的影响

Effects of Different Planting Densities on Yield of Stubble Film Side Potato

以马铃薯费乌瑞它为试验材料,研究不同种植密度对秋季烟草垄上膜侧套种马铃薯的薯块大小和产量的影响,从长势和验收结果来看,种植密度为4 446株/667 m2时产量最高,与其他处理相比差异显著,经济效益最大,各处理的经济效益从高密度到低密度与对照相比,667 m2增效分别为806.16元,1 326.9元,1 100.82元。这充分说明了秋季留茬膜侧马铃薯节本增效栽培技术的推广应用起到良好的示范作用。

Taking potato Favorita as experimental materials, we studied the effects of different planting densities on the tuber size and yield of stubble film side potato in autumn. The results showed that the treatment with the planting density of 4 446/667 m2 possessed the highest yield, which was significant higher than those of other treatments, and its economic benefit was also the highest. Compared to the control, the economic benefits of the highest density treatment to the lowest density treatment increased by 806.16, 1 326.9 and 1 100.82 yuan/667 m2 respectively. The experiment fully played a good demonstration role in the extension and application of cukivation technology of the stubble film side potato in autumn.
