在北京市农科院蔬菜研究中心的指导下,对菠菜杂交制种有关的性状进行了观察,并进行了杂交制种技术研讨。四年来,生产菠杂9号,菠杂10号杂交一代种12万公斤,累计推广6万多亩,填补了我国菠菜杂交优势利用的空白。 1.菠菜的生长习性菠菜抗寒性较强,可耐0～2℃长期低温。-6～-8℃的短期低温。种子发芽最低温度为4℃,发芽与生长适宜温度为15～20℃。对环境适应性较强,适宜的土壤PH值为5.5～7,在有机质含量较多的砂壤土种植为好。
Under the guidance of the Vegetable Research Center of Beijing Academy of Agricultural Sciences, the traits associated with the hybridization of spinach were observed and the hybrid seed production technology was discussed. In the past four years, a total of 120,000 kilograms of spinach hybrid 9 and spinach hybrid 10 have been produced, and more than 60,000 mu have been popularized to fill the gap in the utilization of hybridization of spinach in China. 1. Spinach growth habits spinach strong cold, resistant to 0 ~ 2 ℃ long-term low temperature. -6 ~ -8 ℃ short-term low temperature. Seed germination minimum temperature of 4 ℃, germination and growth suitable temperature of 15 ~ 20 ℃. Strong adaptability to the environment, the appropriate soil PH value of 5.5 to 7, sandy soil in the organic matter content is better planted.
