富锌生物有机肥的肥效试验

Zinc rich biological organic fertilizer effect test

锌不仅是动物、植物和人体生长发育必要的微量元素,而且是人体最容易缺乏的三种微量营养元素Zn、VA、Fe之一。通过生物强化提高作物的锌含量是改善人类锌营养的最有效措施。稻米作为最主要的主食之一,品质提升对人体健康具有重要作用。通过田间试验,对水稻叶面喷施一种新型的富锌生物有机肥,研究该肥料在水稻上的应用效果,结果表明,喷施有机锌肥通过提高水稻穗数、结实率起到明显的增产效果,喷施浓度为2.2 g·L-1效果最好。庆安水稻产量最高可达11 732 kg·hm-2,增产27.8%,宾县增产42.8%。稻米中锌含量随着喷施浓度的增大而增加,最高可达42.29 mg·kg-1。

Zinc is not only animals, plants and human growth and development of the necessary trace elements, and the body most likely to lack one of the three micronutrient elements Zn, VA, Fe. To increase the zinc content of crops through biofortification is the most effective measures to improve human zinc nutrition. Rice as one of the most important staple food, quality slightly enhance the health of people, and play a crucial role in the promotion. A field experiment on rice foliar spraying of a novel zinc-rich bio-organic fertilizer, to research the effect of the fertilizer in rice, results showed that： the spraying of organic zinc fertilizers by improving the rice panicles, seed setting rate play a significantincreased yield, the spray concentration was 2.2 g. L1 effect. The Qing＇an rice production up to 11 732 kg-hm2, yield 27.8%, and Bin yield 42.8%. The zinc content in rice increased with the increase of the spray concentration, up to 42.29 mg·kg-1.
