摘　　要：以食用向日葵杂交种龙食葵5号为供试材料,通过五因素四水平正交试验,研究株高、茎粗、叶片数、花盘直径、百粒重、百仁重、结实率等主要农艺性状对向日葵产量、饱满度的影响.结果表明:5月25日播种、公顷保苗24000株、每公顷施N 70 kg、P_2O_545 kg、K_2O 50 kg能有效的提高食用向日葵的饱满度和产量,从而提高经济效益.百仁重与籽仁率的相关系数达到显著正相关,相关系数为0.502,与籽仁率间接显著正相关的是茎粗和百粒重,与产量性状显著正相关的性状有百粒重、单株成粒数、结实率,相关系数分别为0.409、0.869、0.740.提高向日葵产量的主要性状是茎粗、百粒重和结实率,其中百粒重显著正相关,结实率为极显著正相关.The effects of major agronomic traits such as plant height, stem diameter, leaf number, disk diameter, 100- grain weight, 100 -year weight, seed setting rate on the yield and fullness of sunflower were studied by using the sunflower hybrids The The results showed that： 24,000 plants were planted on 25 May, 24,000 plants per hectare, N 70 kg per hectare, 45 kg of P20s kg and K20 50 kg could effectively improve the fullness and yield of edible sunflowers, thus improving the economic benefits. There was a significant positive correlation between the correlation coefficient and the seed kernel rate, and the correlation coefficient was 0.502, which was significantly positively correlated with the seed kernel rate. The characters with significant positive correlation with yield traits were 100 grain weight, grain number per plant, seed setting rate, correlation coefficient were 0. 409, 0. 869 and 0. 740 respectively. The results showed that the yield of sunflower was mainly stem diameter, 100 -seed weight and seed setting rate, among which 100 -grain weight was positively correlated and seed setting rate was extremely significant positive correlation.
