据联合早报报道

(北京/上海综合讯)中国计划明年扩大转基因玉米的试点种植,数量据报将是今年的两倍多。

据路透星期五(12月15日)社报道,中国农业农村部上月举行了一次会议,一名听取了会议提案简报的消息人士称,转基因玉米明年将获准在八个省份种植,总面积约1000万亩,其中包括东北省份辽宁。东北是中国最重要的玉米种植区,这将是转基因玉米首次获准在辽宁这一传统农业省份种植。

转基因玉米也将首次在广西西南部地区种植。不过,中国这项农业种植计划尚未公开,仍有可能发生变化。

消息人士称,转基因玉米最终的种植面积将由各省决定,预计各省将采取限制,指定具备种植资格的县镇。

另两名熟悉情况的消息人士也指出,中国的转基因种子开发商和育种者正在为1000万亩转基因玉米的种植做准备。其中一人称,大家都在等待官方颁发证书,以允许其出售转基因种子,这一证书可能在未来一个月内签发。

中国近年逐步扩大了转基因产品的试点种值,《证券时报》早前引述业内人士称,2021年中国政府确定转基因试点200亩,2022年是10万亩,今年大幅增加到390万亩,最终推广面积约400万亩左右。

中国政府在转基因的推广上非常审慎,尽管允许进口转基因谷物,但不允许转基因玉米种子完全商业化销售。

不过,由于与主要玉米出口国美国的关系不稳定,以及主要玉米种植国乌克兰正在经历战争,这都促使中国政府重视玉米自给自足的问题,包括未来可能种植产量更高的转基因农作物。

河北、内蒙古、吉林、四川、云南五省区20县今年启动了转基因玉米大豆试点种植。中国农业部农村部称,试点取得明显成效,“充分证明了(中国)国产转基因作物的优良特性和发展潜力。”

目前尚不清楚中国何时会允许转基因玉米和大豆的全面商业化。中国农业部12月7日发布通报,37个转基因玉米品种和14个转基因大豆品种获审定通过,包括隆平高科旗下公司、北京大北农科技公司、登海种业的转基因玉米品种。

而根据中国相关条例,转基因品种获得生物安全证书后,需要通过品种审定获得种子生产和经营许可证,才可以进入商业化生产应用。

由于庞大的猪鸡饲养对饲料需求不断上升,中国近年来已成最大玉米进口国。中国在转基因玉米方面的需求与种植动态,正受到全球供应商的密切关注,如果中国国内产量增加,可能将大幅减少对进口玉米的需求。
