Characteristics and traits of large green jujube: late-maturing, flowering period from late August to late October, fruit ripening period from mid-January to late February of the following year; large leaves with obvious wrinkling on the leaf surface; beautiful fruit appearance, large fruit, crisp and sweet, good flavor; average single fruit weight 164.6 grams; high yield potential, comprehensive traits superior to the currently main cultivated green jujube varieties "Wuqian" and "Misi"; soluble solids content 11.7%, total acid content 0.22 grams/100 grams, vitamin C content 45.3 milligrams/100 grams; after multi-point trial planting in Dongguan, Huizhou, Heyuan and other places from 2005 to 2007, the traits showed stable and consistent performance.
Yield performance of large green jujube: trial planted in Dongguan Botanical Garden, Boluo Yinong Farm and Heyuan Yuanfa Farm respectively in 2006 and 2007, bearing fruit in the same year of planting. Average yield per mu was 1900 kilograms in 2006 and 2008 kilograms in 2007. Yield per plant about 85 kilograms.
Key points of large green jujube cultivation techniques:
(1) Proper sparse planting: 20-25 plants per mu;
(2) Timely planting, reasonable pruning: planting time from March to April, low grafting and variety replacement of large trees should be carried out from March to May, if delayed it is not easy to bear fruit in the same year; appropriately retain more main fruiting branches, when pruning remove the terminal buds to promote lateral branch growth, and promptly cut off branches inside the canopy that receive poor light;
(3) Reasonable fertilization: generally fertilize once each during the five periods of vegetative growth stage, 1 month before flowering stage, young fruit stage, fruit expansion stage, and harvest stage; phosphate fertilizer must not be applied during the young fruit stage and fruit expansion stage; apply phosphate fertilizer and boron fertilizer once additionally at the initial flowering stage;
(4) Reasonable arrangement of pollinator trees: select "Tianmi" and "Gaolang No. 3" which bear elongated fruit as pollinator trees, arrange 1 pollinator tree for every 10 plants;
(5) Adopt technical measures to improve fruit quality: first, formulate sweetening cultivation technical measures to increase sweetness, second, use bagging technology to improve its appearance quality.
