摘　　要：为了解浙北地区单季稻生产过程中的施肥情况,以进一步推广化肥高效利用技术,于2022年10—11月,在湖州市南浔区调查单季稻种植大户45户。数据表明,以南浔为代表的浙北地区,常规稻种植户的平均氮、磷、钾肥用量分别为228.0、63.0、93.0 kg·hm^(-2),杂交稻种植户的平均氮、磷、钾肥用量分别为258.0、75.0、96.0 kg·hm^(-2)。杂交稻和常规稻种植户的化肥用量已趋于优化,但磷肥和钾肥施用量在不同农户之间存在较大的变幅。所调查农户中,施肥次数在2次以上的农户超过总调查数的50%,此外有43户采用配方肥,采用传统复合肥的仅有2户,表明分次施肥、施用配方肥等技术已逐渐被农户所接受。但数据同时表明,绝大多数农户在施肥时,仍采用撒施的方式,仅有2户采用侧深施肥的肥料高效施用技术,且多数农户并未依照测土配方技术来施用配方肥,未来需针对上述问题加强推广工作。In order to clarify the fertilization methods in the single season rice production system in the north region of Zhejiang Province to promote efficient fertilizer utilization technologies,a farmer survey was conducted from September to October in the year of 2022 in Nanxun District,Huzhou City,and 45 farmers were surveyed.The survey results indicated that the average applied amount of nitrogen,phosphorus and potassium for inbred rice were 228.0,63.0 and 93.0 kg·hm^(-2),while for hybrid rice were 258.0,75.0,96.0 kg·hm^(-2),respectively.The fertilizer applied amount for inbred and hybrid rice had been optimized,however,a large change was observed in the phosphorus and potassium application amount among the 45 farmers.The farmers who applied fertilizer for more than twice was over half of the total farmers in this survey,and 43 farmers used formula fertilizer instead of the traditional compound fertilizer,which indicated the split topdressing technology and the formula fertilizer were gradually accepted by farmers.However,the survey results also indicated that most of the farmers still spread the fertilizer into the fields when fertilizing,only 2 farmers used the side deep fertilizing technique.Nevertheless,most of the farmers did not use formula fertilizers according to soil testing formula technology.So,it is necessary to strengthen promotion work to solve the above problems.
