蓖麻植株生长茂盛,一般株高可达1m米以上,对水分、养分的需求量也较多,能一直生长到被霜冻死为止。为了控制蓖麻生长过于茂盛,在全生育期中合理地利用水分、养分,使之良好生长发育,果穗在下霜之前都能成熟,减少秕粒率,提高品质和产量,达到省力栽培的目的,从1987—1989年进行了蓖麻打(木叉)留果穗栽培技术研究。结果归纳如下。 Castor plant lush growth, the general plant height of up to 1m meters above the water, nutrient requirements are also more, can grow until frost death date. In order to control the growth of castor too lush, in the whole growth period of rational use of water, nutrients, so that the growth and development of good, before the frosted ears can mature, reduce the rate of grain, improve quality and yield, to achieve the purpose of labor-saving cultivation, from 1987-1989 castor dozen (wood fork) to stay ear cultivation techniques. The results are summarized as follows.
