胡麻对水肥的要求是很敏感的。及时采取有效技术措施,满足胡麻生长发育对水肥的要求,是提高胡麻单产的重要一环。胡麻从土壤中吸收养分以氮磷钾为主,其中氮素需要量最多。从出苗至开花终期占整个生育期90%以上。因此,氮素化肥作种肥和追肥,满足苗期至开花期对氮素的要求,才能使胡麻根系发达,植株茂盛,籽粒饱满,增加产量和纤维。对磷素的吸收从出苗到现蕾期需要量最大。磷肥作种肥或追肥对促进幼苗根系发育,生长,花蕾形 Flax is very sensitive to water and fertilizer requirements. Timely take effective technical measures to meet the flax growth and development of water and fertilizer requirements is to improve flax yield an important part. Flax absorption from the soil nutrients to nitrogen, phosphorus and potassium-based, of which nitrogen needs the most. From emergence to flowering the end of the entire growing period accounted for more than 90%. Therefore, nitrogenous fertilizer as seed fertilizer and dressing, seedlings to flowering to meet the requirements of nitrogen in order to make flax roots developed, lush plants, full grains, increase production and fiber. The absorption of phosphorus from budding to budding the largest demand. Phosphate fertilizer for seed or top dressing to promote seedling root development, growth, bud shape
