摘要

背景：水稻是人类的主要粮食作物，为了生产足够的粮食，水稻通常与旱地作物轮作。为了验证在以水稻为主的集约化种植系统下，能否同时实现水稻的高产和优质，以确保粮食安全。从 2014 年开始，研究人员对小麦-水稻（WR）、油菜-水稻（RR）、大蒜-水稻（GR）、蚕豆-水稻（BR）和土豆-水稻（PR）这五种长期水稻-高地轮作方式进行了研究，调查了水稻的产量以及稻谷中 24 种元素的含量：结果表明：镁、锌、铜、砷、钼和锑的浓度在胚乳层中最高，而银和镉的浓度在稻粒的不同部位变化不大。在 GR 条件下，胚乳中 Al、Ti、V、Si、Fe 和 Tl 的浓度较高，而在 PR 条件下，Se 的浓度最高。此外，在补充氮的情况下，GR 和 PR 的产量高于其他三种轮作方式，PR 和 WR 的持续产量指数大于 0.8：考虑到胚乳中有毒元素（As、Cd 和 Pb）和营养元素（Ca、Fe、Zn、Se、Cu 和 Mg）的浓度以及谷物产量，PR 在不同氮肥处理下可同时实现高产、高营养和低毒。在此，我们就以水稻为基础的种植系统的选择提出了新的见解，重点是生产高产、营养和安全的水稻。© 2024 化学工业学会。

High-yield rice with rich nutrition and low toxicity can be obtained under potato-rice cropping system.

Background: Rice is often rotated with dryland crops to produce sufficient foodstuff, as rice is the main food crop of humans. In order to verify whether under the intensive rice-based cropping system, high yield and good quality of rice can be achieved simultaneously to ensure food security. Five long-term paddy-upland rotations - wheat-rice (WR), rapeseed-rice (RR), garlic-rice (GR), broad beans-rice (BR) and potato-rice (PR) - were conducted from 2014 to investigate rice yield, along with the profiling of 24 elements in rice grain.

Results: Mg, Zn, Cu, As, Mo and Sb concentrations were highest in the aleurone layer, and Ag and Cd concentrations showed little variation among different parts of the rice grain. Al, Ti, V, Si, Fe and Tl concentrations in the endosperm under GR were higher, while the Se concentration under PR was the highest. Furthermore, the yield of GR and PR were higher than the other three rotations with N supplementation, and the sustainable yield index of PR and WR were larger than 0.8.

Conclusion: When we consider the concentration of toxic (As, Cd and Pb) and nutrient elements (Ca, Fe, Zn, Se, Cu and Mg) in the endosperm and grain yields, PR can simultaneously achieve high yield, high nutrition and low toxicity with different nitrogen treatments. Here we provide novel insights regarding the selection of rice-based cropping systems, focused on producing nutritious and safe rice with high grain yield. © 2024 Society of Chemical Industry.
