本研究探讨了通过培育理想株型以克服母本撒播制种潜在的倒伏危机的技术途径。该文表述了3个主攻要素的集合:1.培育庞大、高活力的根系群,改善耕层土壤结构,提高稻株固着力。2.培育矮壮、竖立、紧凑型植株,保持良好的光合姿态,降低重心,提高稳定性能。3.应用生化调控手段,使之既解除包颈,又不使植株伸长超高。其技术途径可归纳为:起垄栽培、节水勘灌;适时、适量喷施植物生长调节剂多效唑(MET)、九二○(GA3)。它们之间促进与制约的交互作用,成功地实现了理想株型的塑造。
This study explored the technical approach to overcome the potential fall-out crisis by sowing seed by breeding an ideal plant type. This article presents a collection of three key elements: 1. To cultivate a large and highly dynamic root system to improve the topsoil structure and improve rice plant fixation. 2. Cultivate short, erect, compact plants, maintain good photosynthetic attitude, lower center of gravity and improve stability. 3. The application of biochemical control measures, so that it will not only relieve the neck, but also make the plant elongation is too high. Its technical approach can be summarized as: Ridge cultivation, water conservation irrigation; timely, appropriate spraying of plant growth regulator paclobutrazol (MET), nine two ○ (GA3). The interaction between them to promote and restrict the successful realization of the ideal plant shape.
