Secondary Yield Characters of Crops and Their Exploitation
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.
