Abstract

用野生大豆嫁接大豆的方法，涉及一种将野生大豆嫁接到大豆植株上，培育出大豆新品种的方法。本方法如下：将野生大豆豆粒育苗，将普通大豆育苗，普通大豆豆苗出土长五片叶移栽到试验田，待株杆长高到15厘米，将离地6厘米高、离芽片叶2厘米的枝条剪去，植株作为砧木，并在砧木上开2厘米深的槽，将野生大豆幼苗的四片叶幼芽剪下，嫁接到砧木上，得嫁接大豆植株。用本方法嫁接的大豆单株，荚长粒大，扁形奇特，单荚3粒至4粒的为多，也有少数5粒的；植株所结的豆粒为金黄色、蛋园形、黑脐，百粒重一般高达30克至33克；豆粒的蛋白质总含量为70.21％。

Description

用野生大豆嫁接大豆的方法
技术领域  本发明涉及一种将野生大豆嫁接到大豆植株上，培育出大豆新品种的方法。
背景技术  本申请人在居住地发现了几株如图1所示的，形状似野生四徒豆的野生大豆植株，它象野生豆科的大豆属双子叶植物纲，归豆科大豆属，其结荚多，豆荚细长，豆荚内豆粒小，金黄色、蛋园形、黑脐。豆荚内3粒至5粒豆粒占85％以上，不象本地大豆，有的只有一粒荚。煮着吃，是否可食用，味鲜美还有甜味。
发明内容  本发明的目的是针对上述现状，旨在提供一种将野生大豆嫁接到大豆植株上，培育出大豆新品种的方法。
本发明目的的实现方式为，用野生大豆嫁接大豆的方法，按如下步骤进行：
A、将野生大豆豆粒用营养钵育苗方法育苗，
B、将普通大豆用在塑料棚内营养钵育苗法育苗，
C、普通大豆豆苗出土长五片叶移栽到试验田，待株杆长高到15厘米，将离地6厘米高、离芽片叶2厘米的枝条剪去，植株作为砧木，并在砧木上开2厘米深的槽，
D、将野生大豆幼苗的四片叶幼芽剪下，剪口处的皮稍去些后，嫁接到砧木上，得嫁接大豆植株。
用本方法嫁接出的植株，荚长粒大，扁形奇特，单荚3粒至4粒的为多，也有少数5粒的。植株所结的豆粒为金黄色、蛋园形、黑脐，百粒重一般高达30克至33克；豆粒的蛋白质总含量为70.21％。
附图说明
图1为野生大豆植株图
图2为嫁接大豆植株图
图3为嫁接大豆豆粒图
具体实施方式  本方法如下：将野生大豆豆粒育苗，将普通大豆育苗，普通大豆豆苗出土长五片叶移栽到试验田，待株杆长高到15厘米，将离地6厘米高、离芽片叶2厘米的枝条剪去，植株作为砧木，并在砧木上开2厘米深的槽，将野生大豆幼苗的四片叶幼芽剪下，嫁接到砧木上，得嫁接大豆植株。
参照图2，用本方法嫁接出三个大豆单株，荚长粒大，扁形奇特，单荚3粒至4粒的为多，也有少数5粒的。最高单株高1.1米分枝12个呈扇形，结荚728个种子净重526克，第二株高1米分枝11个结荚682个，种子净重518克，第三株高98厘米分枝10个，结荚598个种子净重502克。按这些植株分析，嫁接大豆得平均亩产应为650公斤，是(035)鄂豆4号对比的158.3公斤，产量为其4.11倍。参照图3，嫁接植株所结的豆粒为金黄色、蛋园形、黑脐。
本制备方法冬凌草甲素文献值吻合。中国农业科学作物品种资源所对用本方法所结的大豆，作了分析，分析结果为：蛋白质46.54，氮转换为蛋白蛋白质的系数为6.25、脂肪17.42、脂肪17.42％，蛋白质总含量为70.21％.
