蜜蜂授粉在西葫芦制种上的应用研究

The Application of Honeybee Pollination in Pumpkin Seed-making

利用蜜蜂为早育一代西葫芦杂交种授粉。结果，西葫芦生长速度提高了8．5％，每公顷减少人工授粉费用1800元，种子数量每株增加485粒，每株种子重量增加4．99g，每公顷增产187.13kg，增加收入4116元，完全可代替人工授粉。

This paper studies the honeybee pollination to early green generation pumpkin hybridize species. The results show that honeybee pollination tuskes the growth speed of pumpkin rise by 8. 5%;the artificial pollination expensive reduces 1800 yuan/hm2; the amount of seed rises by 48. 5 grains perplant; the weight of seed rises by 4. 99g per plant; the production rises by 187. 13kg/hm2; the incomerises by 4116 yuan. So honey -bee pollination may replace artificial pollination completely.
