摘要
为了提高相关研究和生产管理的效率,本文探讨了非传统作物产量性状的特性及其利用研究对策,同时提出了作物原生产量(即一次形成,一造一次只收获的作物产量)和次生产量(即反复形成,多次收获的作物产量)的概念,并以橡胶树干胶产量为例,阐述了次生产量具有可反复合理收获胁迫(由收获引起的某种伤害)形成的产量特性;并探讨了采用收获胁迫诱导次生产量性状表现,以改进橡胶树产量评价方法或获取橡胶生产最佳经济效益等在相关研究和生产管理方面的对策。
With the objective to explore the characters of non-traditional crops yield and the application, the concep of secondary yield, the crop yield formed and harvested repeatedly, and the concept of protogenesis yield, the crop yieldformed and harvested once for one crop, were proposed. Taken rubber tree latex production for an example, the secondary yield characters formed by multiple rational harvest stress, namely harvest time and harvest technique, were analyzed, and the strategies of the related studies and production managements of rubber by adopting harvest stresses to improve the rubber yield evaluation method by means of inducing the expression of secondary yield earlier, or to gain the best economic benefit were discussed.
