药剂拌种的时间与方式对马铃薯生长和产量的影响

Effect of Different Time and Way of Seed Dressing on Potato Growth and Yield

在大田条件下,以马铃薯Lt-5为试材,探讨了药剂拌种时间和不同方式拌种后马铃薯存放时间对马铃薯产量及品质的影响。结果表明:马铃薯切薯后晾晒5h以上拌种对增产及保证马铃薯品质效果最好,与立即拌种相比,晾晒后可以减少马铃薯薯块中畸形和疮痂病病薯率;种薯切块拌种后至播种前时间间隔越长,产量越低,拌种方式上干拌好于湿拌。

Lt-5 was taken as experimental material to study the effects of different time and way of seed dressing on potato growth and yield in the field. The result showed that drying 5 h then seed dressing had the best effect on increasing yield and quality,compared with seed dressing immediately, drying before seed dressing could decrease the rate of teratogeny and scab potato;The longer of the time between seed dressing and sowing the lower of the yield. The dry mixing produced the best effect than wet mixing.
