Survey selection, breeding of fine varieties of fresh jujube for 'the Zhongmou brittle abundance', through a variety comparison trials and regional observation test to observe the growth and development characteristics; different planting patterns, herbicides, and grafting, cuttings of 'the Zhongmou crisp Fung' quality seedlings micropropagation. The main findings are as follows: 'the Zhongmou brittle abundance' jujube in Zhongmu County of Jujube Resources census in 2001, in Zhongmou County Yao hometown found. 2002, after grafting, in Zhongmu County jujube Institute within the comparison test. 2004-2007 worked in the Zhongmu County jujube Institute, Xinzheng jujube science Institute, Henan Province Neihuang, Qi County, Puyang City, Sanmenxia City conducted varieties regionalized experiments. 2007-2008, worked in Zhongmu County, Xinzheng City, Neihuang, Qi County, Sanmenxia City, Puyang City, and other places to promote demonstration cumulative promotion area of ??more than 50hm2, and officially named as the 'the Zhongmou brittle abundance'. Excellent fresh jujube varieties, 'the Zhongmou brittle abundance', the second year of planting results 4-5 years into the flourishing, 6-year-old fruit tree strains producing 15kg; bud Zhongmu region in mid-April, late May, early flowers, mature in mid-September, the fruit development period 110d; the Shushi medium, the jujube head length 55.3cm, secondary branches 23.8cm, the jujube hanging length 17.71cm, with leaves 15.3 per jujube hanging results 2.2; fruit succulent crispy, sap, single weight 5.91g, stone weight 0.42 g. 22.38% of the soluble solids content, soluble sugar content of 17.7%, the vitamin C content 367mg/100g 'Zhongmu brittle abundance' wide jujube adaptability, strong resistance traits and stability in all parts of Henan. 'Semen mulching' the sowing pattern emergence time for 11d, 96% germination rate, height 123cm, compared to their cropping patterns, shorten breeding time, improve the germination rate is most conducive to the growth of the rootstock seedling planting mode . Grafting research, scion collected the best time is early in late March to April; acquisition growth and fulfilling the annual development branches as scion, seedling quality; of Zhongmou region with embedded Zhijie grafting methods in mid-April to 5 grafted scion of early May, the survival rate is 90%. Different herbicide treatments Zhongmu brittle Fung 'jujube seedling emergence and weed control trials, 48% butralin treatment effect best, the germination rate of more than 94%, the early weeding 98.8%, the effect is even more pronounced of late weeding, almost gone weed growth, the more significant is that the herbicide does not affect the emergence in the late. Followed by 50% acetochlor treatment effect. Different factors 'Zhongmu brittle abundance' rooting rate of cutting seedling root growth test, each the result of a combination of factors Selection from June 5 to June 25, the selection of the the jujube head sticks or secondary branches as cuttings, cuttings in sandy loam soil, inserted with IBA1000 mg / L or ABT61000mg / L speed dipped 15s.
