This research first studied the effect of different seeding timeand different seeding density on economy properties of Cole as oilseedsand vegetable which was bred by oil crop department of HunanAgriculture University and rapeseed's output. Then this research studiedthe effect of the different seeding time, different seeding density anddifferent length of fresh shoot on outputs and qualities of fresh shoot andanalyzed economic benefits of different treatments. The results of thestudy stated:1. Seeding time and growth density had obvious effects on outputfactor of "hybridizing 780". Appropriate shifting to an earlier timesowing seeds increased "hybridizing 780" vegetative growth. The moredry mass which were accumulated could offer the more nutrient to thegrowth of Cole when fresh shoot were picked. The branch number in thefirst time, the branch number in the second time and fruit numberdeclined through seeding time suspending. And within a certainty range,economy properties of "hybridizing 780" declined through seedingdensity increasing.2. The effects of seeding time, density and length of fresh shooton output of"hybridizing 780" fresh shoot is obvious. It was the effectiveway by sowing seeds in an earlier time and increasing the Cole'scultivating density increasing fresh shoot. When it was sowed before 10September, it increased 112500-150000 plants every 1hm~2 and the output of fresh shoot (15-20cm long) overrun 10000kg.3. The length of which fresh shoot was picked had thebiggest effect on the nutrient quality. When the length of fresh shootwas under 15cm because the leaf of fresh shoot had a bigger proportionmaking capability of tasting change bad and not bearing a store andtransportation. When it was under 25cm because the content of cellulosewas on the high side making capability of tasting change bad. When thelength of"hybridizing 780" fresh shoot was 35~55cm, the length of freshshoot 15~20cm which was picked was suitable.4. The economic benefit of "hybridizing 780" which was a newbreed was the biggest when it was sowed before 5 September and plant112500~150000 plants every 1hm~2 and pure eaming of 1hm~2 was to12000(RMB).5. When "hybridizing 780" cultivated, we should attachimportance to the basic fertilization, fertilize much organic fertilizationand cautiously fertilize fertilizer. According standard of "green" vegetableprevent and cure disease and insect pest. Thereby we could improved thequality of fresh shoot and made sure the tasting safety of fresh shoot by it.
