前言水稻是我区的主要粮食作物之一。生产上所用的品种,主要是地方品种。其优点是:子粒大,幼苗生长快,耐淹灌能力较强,容易保苗,对土壤肥力要求不高。但其最大缺点是:容易感染稻瘟病,易倒伏,着粒稀少,很容易落粒,产量不高不稳。为了选育稳产高产水稻新品种,几年来经过引种鉴定,确定了公交12号品种具有稳产高产、耐肥、稻瘟病轻、抗倒伏等特点,适合在我区引黄灌区栽培,栽培面积正在扩大。
Introduction Rice is one of the main food crops in our region. The varieties used in the production, mainly local varieties. Its advantages are: large seeds, seedlings grow fast, resistant to flooding irrigation ability, easy to seedlings, less demanding on soil fertility. However, its biggest drawback is: susceptible to rice blast, easy to lodging, sparse grain, it is easy to drop, the yield is not high and unstable. In order to breed new varieties of stable and high yielding rice, after several years of introduction and identification, it has been confirmed that the bus No.12 has the characteristics of stable and high yield, resistance to fertilizer, light blast and lodging resistance and is suitable for cultivation in the irrigated area of Yellow River in our district. The cultivation area is expanding .
