1.子叶展开阶段茄子的子叶展开阶段的诊断和对策与甜茭相同,可参照。 2.育苗阶段茄子与甜茭不同,氮素充足,夜温低时,在嫩叶上可看到花青素,叶色浓。相反,缺氮、夜温高、日照不良时,叶色淡。花青素浓度大的情况下,顶芽成勾状弯曲。在低温条件下,氮素肥料的肥效越足,顶芽越弯曲,这与硼素的吸收受影响有关。 1. cotyledon stage Eggplant cotyledon stage of development and diagnosis and countermeasures the same, can refer to. 2 nursery stage eggplant and sweet 茭 different, adequate nitrogen, night temperature is low, you can see on young leaves anthocyanins, leaf color thick. In contrast, nitrogen deficiency, high night-temperature, poor sunshine, pale leaves. In the case of large concentrations of anthocyanins, the top bud becomes hooked. Under the condition of low temperature, the more fertilizers nitrogen fertilizer, the more curved bud, which is affected by the absorption of boron.
