抗除草剂简化栽培型谷子品种朝谷58的选育及配套栽培技术研究

Breeding and Cultivation Technique of Herbicide-resistant Simplifying Cultivated Millet Varieties‘North Valley 58'

[目的]选育抗除草剂简化栽培型谷子品种朝谷58并探究其配套栽培技术。[方法]运用多系品种的概念,从河北省谷子研究所引进抗拿捕净的谷子材料冀谷25与性状较好的优良春谷品种朝谷9号杂交,育成了适宜简化栽培的多系谷子新品种朝谷58;通过研究姊妹系的适宜混配比例、播种量、播期、除草剂种类、除草剂适宜喷施时期及剂量等提出了与其配套的简化栽培技术。[结果]朝谷58由抗拿捕净的新品种323-1及不抗拿捕净的同型姊妹系323-2组成,2012年3月通过辽宁省杂粮备案登记。该品种抗倒伏、抗旱且抗多种病害。与该品种配套的简化栽培技术实现了同时化学间苗和化学除草,喷药后7 d左右自动达到大田生产所需的留苗密度,出苗30 d内对杂草防效达90%以上,全生育期基本不需要人工间苗和人工除草。[结论]为该品种在生产上的推广应用提供了参考。

[ Objective ] The aim was to screen out herbicide-resistant simplifying cultivated millet varieties ＇ North Valley 58＇ and explore its matched cultivating techniques. [ Method] The concept of multi-line varieties, the introduction of anti-take-bashing net millet materials lazy valley on the 1 st and Spring Valley excellent traits better towards the valley on the 9th of hybrid varieties from Hebei Province Institute of Mil- let, bred suitable for cultivation and more simplified system Millet Variety ＇ North Valley 58＇. Mixed proportion sister through appropriate re- search department, sowing, sowing date, herbicide type, herbicide spraying time and appropriate dose, etc. , instead of supporting the pro- posed simplified cultivation techniques. [ Result] North Valley 58＇ was composed of anti-sethoxydim new varieties ‘323-1 ＇ and not the same type of herbicide-resistant sister lines ‘323-2＇ , and was finished by Liaoning Province grains registration in March of 2012. The variety was resistant to lodging, drought and various diseases. The matched cultivating techniques of ＇ North Valley 58 ＇ achieved the same chemical thinning and chemical weeding, and automatically achieved the desired field production seedling density spraying after about 7 days; the con- trol effect of 30-day emergence weed was more than 90% ; the basic need of artificial growth period thinning and weeding. [ Conclusion] The results provide reference for the application of ＇ North Valley 58＇ in production.
