一、畸形果1.形成原因在低温、多肥(主要是氮肥)、水分、光照不足,养分过分集中输送到正在分化的花芽中,花芽细胞分裂过旺,心皮数增多,开花后心皮发育不平衡,而形成多心室畸型果。幼苗期氮肥过多,冠根比例失调也会产生畸型果。此外,喷花浓度过高或重复喷花,也会造成畸形果。
First, the formation of deformities 1. Forming reasons at low temperature, more fat (mainly nitrogen), water, light, nutrients are too concentrated delivery to the differentiation of flower buds, flower bud cell division, the number of carpels increased, Unbalanced development, and the formation of multiple ventricular malformations. Nitrogen fertilizer in seedling stage, the proportion of crown root disorders can also produce abnormal fruit. In addition, high spray concentration or repeated spray, can also cause deformities.
