马铃薯的现蕾期正是块茎形成期,盛花期正值块茎增长期。在现蕾至盛花这一阶段,由于呼吸作用增强,要消耗大量同化产物,影响块茎的形成和增长。如果通过去蕾去花,减少养分的消耗,就能提高马铃薯的产量。1985年,我们进行了人工去蕾去花试验,具体作法是:第一次去蕾去花是在植株现蕾开花数占25%—30%;的时候进行,以后每隔3—4天去一次,连去2—3次,最后一次必须彻底干净的去掉花和蕾。在去蕾去花时,用手捏住花序基部。向上提掐即可,要注意防止损伤叶片。经试验,3人同 Potato budding period is the tuberous formation, flowering period is tuber growth period. In the process of budding to flowering, due to increased respiration, a large amount of assimilation products are consumed, affecting the tuber formation and growth. If you go to spend buds to reduce nutrient consumption, can increase the yield of potatoes. In 1985, we conducted a manual test to the bud to the specific practice is: the first to go to the bud is the flower buds in the number of accounts for 25% -30%; when, after every 3-4 days to go Once, even to 2-3 times, the last must be thoroughly clean to remove the flowers and buds. When you go to the bud to spend, pinch the inflorescence base. Pinch up to mention, pay attention to prevent damage to the leaves. After testing, 3 people with
