塔穗蓖麻引入我省以来,其丰产潜力得到普遍认可。但因熟性偏晚,分技力旺盛,使推广、普及受到了限制。永和县在推广塔穗大青麻和红秆塔过程中,试验、总结出不留主穗打掐法,有效地解决了当地无霜期较短而品种生育期较长的矛盾,产量大幅度提高,为推广塔穗蓖麻品种创出了一条新路。一、不留主穗打掐法的方式与特点不留主穗打掐法是在主茎顶端苞叶内刚刚开始分化形成的微小花序时把项梢打掉,选留主茎上部3—4个强芽成穗,主茎中、下部及分枝小的其余腋芽全部打掉。长成后远望就象高粱地一样只见德,不显叶;近观每株有3—4个密实的长果穗,就象三四柱香一样。因此,永和县的群众也把这种方法形象地叫做“三柱香”整枝法。其特点是:
Since the introduction of castor bean into the province, its high yield potential has been widely recognized. However, due to late maturity, sub-skills, so that promotion, universal access has been limited. Yonghe County in the promotion of tower spike big green hemp and red straw tower in the process, the test concluded that the main spike do not stay pinch method, the effective solution to the local frost-free period is shorter and the longer the growing period of contradictions, a substantial increase in output, To promote the tower castor varieties to create a new road. First, do not stay the main spike pinching method and characteristics of the main spike pinching method is not in the main stem tip of the husk just began to differentiate the formation of tiny inflorescence items knocked out, select the main stem left 3-4 A strong bud into the ear, the main stem, the lower branches and the remaining small axillary buds all destroyed. After growing into a distant like as sorghum to see Germany, not significant leaves; near view of each plant has 3-4 dense long ears, as the same thirty-four incense. Therefore, the people of Yonghe County also vividly call this method the “three-column incense” pruning method. Its characteristics are:
