红花是经济作物。红花油在食用、医学、工业等方面有着广泛的用途。干花国外用以提取色素做食品染剂、丝绸、棉布染料,化桩用品。我国采花入药历史悠久,它有破瘀活血、通经之功效,并有一定数量的出口。红花采花后对种子产量有无影响?为此,我们进行了两年的试验观察。 1980年用油用B—54品种做材料,在整个花期每天上午采掉当天开的小花,结果千粒重比邻近不采花的高3.85克,收获指数高4.36％。 Safflower is a cash crop. Safflower oil in food, medicine, industry and other areas have a wide range of uses. Dry flowers used to extract pigments for food dyes, silk, cotton dye, pile supplies. Chinese medicine has a long history of plucking flowers, it has Huayu blood circulation, the effect of pass through, and a certain number of exports. Whether the output of safflower has any effect on the seed yield? For this reason, we conducted two years of experimental observation. In 1980, the oil was made from B-54 variety and the floret of the same day was taken every morning throughout the flowering period. The result showed that the 1000-grain weight was 3.85 grams higher than the non-flowering flowers nearby, and the harvest index was 4.36% higher.
