The rural technological service project “Chestnut standardized and efficient cultivation technology”, conducted by Institute of Changli Fruit Research, got the significant effect through field test on September 16.
The result through field test showed that the main planting varieties in demonstration base were “Dabanhong”, “Yanshan Zaofeng”, “Yanshan Duanzhi” and so on. The main practical technologies used in orchards were grafting with the top, pruning technology for alternate shaping, grass naturally growing in the field, and IPM. In terms of two varieties’ production, the single chestnut weighed 9.3g and 8.7g respectively for “Yanshan Duanzhi” and “Dabanhong”, the yield was 232kg and 267kg per mu. Compared with the traditional management, the data collected by the field test in demonstration base was increased 10%-48% for single fruit weight and the yield.
The project has been well demonstrated in the base, the yield, top grade fruit rate and uniformity of chestnut garden have been significantly improved with obvious demonstration effect.
