化控栽培是农业生产上的一项新技术,小麦实施化控栽培,可以调控植株的生长发育,增强其抗逆性,促进早熟、高产。 1、增强抗寒力 小麦拔节初期(2月底—3月初),叶面喷施植物抗寒剂K—1,亩用100毫升兑水35公斤。能明显提高小麦抗寒力,避免“倒春寒”和“晚霜冻”的危害;还能增强光合速率,提早成熟,提高品质,使小麦增产10—30％。 2、防止倒伏 ①、喷施多效唑。在小麦起身期,每亩喷洒200PPm多效唑溶液30公斤,可使植株矮化,抗倒伏能力增强,并能兼治小麦白粉病和提高植株对氮素的吸收和利用率。②、喷施矮
Chemical control cultivation is a new technology in agricultural production. The implementation of chemical control cultivation of wheat can regulate the growth and development of plants, enhance their stress resistance and promote early maturity and high yield. 1, to enhance the cold hardiness wheat jointing early (end of February - early March), foliar spraying plant cold agent K-1, acres of 100 ml watered 35 kg. Can significantly improve the cold resistance of wheat, to avoid the “late spring cold” and “late frost” hazards; but also enhance photosynthetic rate, premature, improve quality, wheat yield 10-30%. 2, to prevent lodging ①, spraying paclobutrazol. During the period of wheat getting up, spraying 30 kg of 200 PPM paclobutrazol per acre can make plants dwarf and enhance lodging resistance, and can cure wheat powdery mildew and improve nitrogen uptake and utilization of plants. ②, spray short
