摘要
通过查阅相关文献和多年来的生产实践经验,总结了番茄的需肥特点和不同生育期、不同茬口、不同栽培和施肥条件下番茄对养分的需求规律和吸收特点,提出了日光温室番茄生产的科学施肥技术:按产量一般在6000～8000kg/667m2,定植前基施有机肥8000～10000kg/667m2,基施纯N6～8kg/667m2、P2O58～10kg/667m2、K2O8kg/667m2。在第一穗果开始膨大到核桃大小时,可进行第一次追肥,施纯N2.0～2.5kg/667m2,P2O52.0～2.5kg/667m2,纯K2O2～3kg/667m2;以后追肥在每穗果膨大到核桃大小时,每次施纯N2.5～3.0kg/667m2,P2O52.0～2.5kg/667m2,K2O3.0～3.5kg/667m2,共追施肥料5～6次。
By consulting the relevant literature and years of production experience,the author summarizes the tomato fertilizer requirement characteristics,nutrient absorption characteristics and the law of demand with different growth period,the different stubble,the different cultivation and fertilization conditions.well as the greenhouse tomato production of scientific fertilization technology,greenhouse tomato scientific fertilization technology：tomato production is generally 6000-8000kg/667m2,before planting organic fertilizer was applied 8000-10000kg/667m2,pure N6-8kg/667m：,the P2058-10kg/667m2,K208kg/667m2.In the beginning of the first spike fruit enlargement to the size of a walnut,can be the first top dressing applied pure N2.0-2.5kg/667ma, P2052.0-2.5kg/667ma, pure K202-3kg/667m2.Later each spike fruit reaching to the size of a walnut,each pure N2.5-3.0kg/667m2, P2052-2.5kg/667m2,K203.0-3.5kg/667mE,top dressing fertilizer 5-6 times in the growing season.
