以2年生观赏桃“迎春”、“元春”为试材,以不加温处理为对照,将根系加温技术引入温室观赏桃生产中,研究了根系加温对温室观赏桃花期、花质等的影响,以解决目前观赏桃温室生产中先叶后花,影响花期、观赏效果的问题。结果表明:根系加温处理提高了观赏桃栽培基质温度,对温室内气温没有明显影响;使花期提前10d以上,缩短花期2d,延长了可观赏期1d以上,花朵直径增大,且始花期、花期、观赏期、花朵直径指标差异极显著;减少了单株花期新梢数量,降低了新梢总长度;促进了根系生长,新根数量和长度显著增加,根系活力提高。试验表明根系加温有效解决了温室观赏桃生产中先叶后花的问题,提高了观赏桃的观赏效果,根系加温技术值得在温室观赏桃生产中推广应用。
With 2-year-old peach ornamental peach, Spring Spring and Yuanchun as the test materials, the root heating technique was introduced into the greenhouse for ornamental peach production without heat treatment. The effect of root heating on the ornamental peach period , Flowers and other effects in order to solve the current production of ornamental peach leaves in the first post-flowering, affecting flowering, ornamental effect. The results showed that root heating increased the temperature of ornamental peach cultivation medium and had no significant effect on the air temperature in the greenhouse. The flowering stage was advanced more than 10 days, the flowering stage was shortened by 2 days, the ornamental stage was extended for more than 1 day, the flower diameter increased, The flower diameter, ornamental period and flower diameter were significantly different. The number of shoots per plant was reduced and the total length of shoots was reduced. The root growth was promoted, the number and length of new roots increased significantly, and the root vigor increased. The experiment shows that the heating of the root system effectively solves the problem of the first leaf after flowering in the greenhouse ornamental peach production and improves the ornamental effect of the ornamental peach. The root warming technology is worth popularizing and applied in the greenhouse ornamental peach production.
