叶面喷肥对芹菜种子产量和质量的影响
Effects of Foliar Fertilizer on Yield and Quality of Celery Seed
摘要
Abstract
This experiment used foliar fertilizer mixed with potassium dihydrogen phosphate and Penggaibao as compound fertilizer and sprayed it at different celery flowering stages taking '08-15' celery (Apium graveolens L.) cultivar as material. The results showed that foliar spraying during the secondary inflorescence flowering stage could not only increase celery seed yield, but also improve 1000-grain weight and enhance germination ability, thus to effectively improve seed quality. The effects of spraying foliar fertilizer at the end of the third inflorescence flowering stage to the early fourth inflorescence flowering stage would make the 1000-grain weight and germination capacity, etc. quality indexes become worse, although the seed yield was increased. Twice successive spraying at the above mentioned stages would have better effect in increasing yield and improving seed quality, but one thing worthwhile to notice is the later spraying could easily damage the flower branch, and field operation is very inconvenient. If spraying at this time is really needed, the row spacing in seed producing field should be large enough.关键词
