番茄在栽培过程中,因受到诸多不利条件的影响,易引起生长发育失调,合理利用化控技术,则可调控番茄体内激素的合成与含量,提高番茄对各种不良环境的适应能力,改善番茄的生长发育状况,是一项方法简便、投入少、效益高的栽培技术。一、苗期培育壮苗番茄在育苗时,很容易徒长,用生长抑制剂处理可有效防止徒长,提高抗旱、耐寒能力,并促进花芽分化。早春育苗于2～4片真叶时喷施一次10×10~(-6)(10ppm)的多效唑或5×10~(-6)～10×10~(-6)的烯效唑,夏秋育苗在2片真叶时喷20×10~(-6)的多效唑或10×10~(-6)的烯效唑。也可于幼苗2片真叶和5～
Tomato in the process of cultivation, due to many adverse conditions, easy to cause growth and development disorders, the rational use of chemical control technology, you can regulate the synthesis and content of hormones in tomatoes to improve tomato adaptability to various adverse environment, improve tomato The growth and development status, is a method is simple, less investment, high efficiency cultivation techniques. First, seedling nurturing seedlings Nursery growth in tomato is very easy to grow, with growth inhibitors can effectively prevent leggy growth, improve drought, cold tolerance, and to promote flower bud differentiation. Early spring nursery in the 2 to 4 true leaves sprayed with a 10 × 10 -6 (10ppm) of paclobutrazol or 5 × 10 -6 -6 10 ~ (-6) uniconazole, summer and autumn Seedlings were sprayed with 2 × 10 ~ (-6) paclobutrazol or 10 × 10 ~ (-6) uniconazole when 2 true leaves were sprayed. Seedlings can also be 2 true leaves and 5 ~
