花生从始花到初见饱果为生育中期。此期营养体与生殖体生长最旺盛,制造积累的干物质最多,速度最快,营养体的90%以上,生殖体的60%以上是在这阶段形成的。因此,科学地加强中期管理,是获得高产的关键。一、巧追花、果肥,促花齐、争果多。花生从始花至单株盛花,株丛迅速壮大,已转入营养生长与生殖生长并进阶段,根、茎、叶营养器官生长迅速,前期有效花大量开放并且大批果针陆续入土结实,这时对养分的吸收急剧增加,对氮、磷、钾的吸收量约为全生育期吸收总量的22—33%。此期缺肥,减少花 Peanut from beginning to full bloom of fruit for the first half of fertility. This period of vegetative and reproductive growth of the most vigorous, the accumulation of the most dry matter accumulation, the fastest, more than 90% of vegetative, genital more than 60% formed at this stage. Therefore, scientifically strengthening medium-term management is the key to achieving high yields. First, clever chasing flowers, fruit fertilizer, promote flower Qi, fight more fruit. Peanut flowers from the beginning to the plant, the plant grow rapidly, has been transferred to vegetative and reproductive growth and advanced stage, root, stem and leaf vegetative organs grow rapidly, a large number of early effective flowers open and a large number of fruit needles one after another into the soil, then Absorption of nutrients increased sharply, the absorption of nitrogen, phosphorus and potassium is about 22-33% of the total growth period of absorption. This period of lack of fat, reduce the flower
