胡萝卜营养丰富,含有大量胡萝卜素、糖和钙、铁、磷等,耐贮藏,宜加工,是冬春主要蔬菜之一,深受消费者喜爱。但由于胡萝卜种皮透水性差,胚小顶土力弱,在气温适宜,水分充足条件下发芽率仅70％左右。因此,播种时创造良好的发芽条件,是保证苗齐、苗全、夺取高产的先决条件。1995年,我们应用先进的流体播种技术,达到了出苗快、出苗齐、长势壮、产量高的目的。 一、流体播种优点 （一）出苗提前,出苗率高。流播时种子经过精选和温水催芽,为其发芽创造了良好的环境,播后第6天出苗率即达89. 6％,而对照第14天出苗率仅51.1％。采用流播比常规播可早出苗 8天,出苗率提高38.5％。 （二）保证水分需要,减少灌溉次数。从播种到收获,流播区仅灌溉4次,比常规播节省5次;出苗30天、60天及收获前测定5-10cm土层含水量,分 Carrot nutritious, contains a lot of carotene, sugar and calcium, iron, phosphorus, resistant storage, should be processed, is one of the main winter and spring vegetables, loved by consumers. However, due to poor permeability of the seed coat of carrot, embryo small top soil weak, suitable temperature, water sufficient germination rate of only about 70%. Therefore, to create a good germination conditions when sowing is to ensure Miao Qi, Miao Quan, to seize the prerequisite for high yield. In 1995, we applied advanced fluid seeding technology to achieve the purpose of quick emergence, emergence, growth and high yield. First, the advantages of fluid sowing (A) emergence in advance, high rate of emergence. Seed flow through the selection and warm water sprouting, creating a good environment for its germination, germination rate reached 89.6% on the 6th day after sowing, while the control on the 14th day emergence rate of only 51.1%. Flowing than the conventional broadcast seedlings can be early 8 days, the germination rate increased 38.5%. (B) to ensure the water needs to reduce the number of irrigation. From sowing to harvesting, the flowering area was irrigated only 4 times, 5 times less than conventional sowing; water content of 5-10 cm soil layer was measured at 30 days and 60 days after emergence and before harvest
