Jatopha curcas fruit picking up method

Abstract

The invention discloses a method for picking fruits of Jatropha curcas, pertaining to the technical field of farming operation. The method of the invention includes the steps of determination of ripeness of fruits, picking of fruits, preparation of tools, picking of fruits on low branches, picking of fruits on high branches and necessary points for attention. When the fruits of the Jatropha curcas completely turn from green to yellow and the seed is found completely black when the seed capsule is peeled, then the fruits can be determined to be ripe and the fruits are harvested once at an interval of 15 days to 20 days since the ripening of fruits. The method of the invention comprehensively takes the characteristics of fruit bearing of the Jatropha curcas into account to save the picking cost, has scientific harvesting and convenient operation and can save more than 78 percent of labor intensity and reduce the cost of fruit picking by over 350 yuan per Mu (one Mu is approximately equal to 666.66 square meter), thus dramatically reducing the production cost.

Description

technical field The invention relates to the technical field of agricultural operations, in particular to a method for harvesting Jatropha curcas fruit. Background technique Jatropha curcas (Jatropha curcas) is a drought-resistant and barren-resistant multi-purpose tree species, widely distributed in tropical or subtropical regions, mainly in America and tropical Africa. my country is mainly distributed in Yunnan, Sichuan, Guangxi, Guangdong, Hainan and other places, with the most in Yunnan, followed by Sichuan. Planting Jatropha curcas can not only increase the vegetation and improve the ecological environment, but also its seeds and sap are widely used in medicine, chemical industry, protein feed, etc. In particular, the crude fat mixture obtained by pressing from seeds can be further chemically transformed to obtain an ideal environmentally friendly mechanical fuel, called biodiesel. In recent years, my country's Yunnan, Sichuan and other places have carried out large-...

AI Technical Summary

Problems solved by technology

The method of the present invention overcomes the defects in the prior art that fruits are harvested as they ripen, and the fruit is picked once every 1-2 days, and the time for picking the fruit is not concentrated, and the labor cost is large; or the picking is late, which affects the quality of the fruit.
