整枝是蓖麻田间管理的重要一环。合理整枝能调节植株体内营养物质的分配和运输,协调营养生长和生殖生长的矛盾,使养分集中供给开花结实,从而促进花序发育,多结籽实,提高产量。蓖麻分枝与果穗生育特性蓖麻分枝力强,具无限生长习性。有的品种主茎长出5片叶,顶端就出现总状花序;也有的品种主茎长出11~13片叶顶端才出现花序。主茎顶端长出的花序为第一次花序。在花序下面的每个叶腋都可抽出分枝,尤
Pruning is an important part of castor field management. Rational pruning can regulate the distribution and transportation of nutrients in plants, coordinate the contradiction between vegetative and reproductive growth, and concentrate the nutrients to flowering and fruiting, thus promoting the development of inflorescences, multiplying the seed and increasing the yield. Castor Branches and Ear Growth Characteristics Castor branches strong, with unlimited growth habit. Some varieties of main stem grow 5 leaves, the top appears raceme; also some varieties of main stem grow 11 ~ 13 leaves top appear inflorescence. The top of the main stem inflorescence is the first inflorescence. Each leaf axil below the inflorescence can be extracted branches, especially
