绪言为了提高糙米蛋白质含量而进行的研究,在栽培技术方面有尾崎1949、尾崎、森山1952、本庄等1966、木户·梁取1968、平1970、平等1970、本庄1971、Nishizawa等1977;在育种方面,有田中和田村1968、Swaminathan1969、片冈1973、东等1974·1976,田中1976片冈1978等的报道。其中,作为栽培技术,出穗后追肥能有效地提高糙米蛋白质含量。作为育种方法,则依靠r射线、次乙基亚胺等引起突变、育种,从而提高糙米蛋白质含 Introduction In order to improve the protein content of brown rice, Ozaki 1949, Ozaki, Moriyama 1952, Honjo 1966, Kido Beam 1968, Ping 1970, Equality 1970, Honjo 1971, Nishizawa et al. , Kazuhiro Tanaka 1968, Swaminathan1969, Kataoka 1973, Tokushima 1974.1976, Tanaka 1976 Kagami 1978 and other reports. Among them, as a cultivation technique, topdressing after heading can effectively improve brown rice protein content. As a breeding method, relying on r-ray, ethylenimine and other mutation, breeding, thereby improving brown rice protein content
