摘要
以海藻提取物为主要原材料浓缩提炼加工而成的有机矿物质营养剂为研究对象,将海藻有机矿物质营养剂替代化学肥料在番茄生产中进行应用,明确其对番茄生长发育的影响,为海藻有机矿物质营养剂替代化学肥料的推广应用提供理论依据。试验设2个处理,以施用0.5%的磷酸二氢钾叶面肥为对照,施用海藻有机矿物质营养剂作为叶面肥为处理,采用随机区组试验,全生育期施用叶面肥10次。结果表明,与化学肥料相比,施用海藻有机矿物质营养剂可以提高番茄苗期的茎粗、叶面积,降低节间长和株高等,促进番茄壮苗;可以提高番茄光合速率,使前期产量增加7.0%,总产量增加7.5%;番茄的可溶性糖含量提高12.8%;番茄叶霉病和灰霉病的病情指数分别为9.6和6.7,降低病原菌的侵染。将海藻有机矿物质营养剂替代化学肥料在番茄生产中应用,在减少化学肥料施用量的同时,可以促进番茄苗期生长、提高番茄产量、减轻病害的损伤程度。
Organic mineral nutrients,which are concentrated and refined from seaweed extract as the main raw material,are used in tomato production instead of chemical fertilizer,so as to clarify its influence on tomato growth and development,and provide theoretical basis for popularization and application of seaweed organic mineral nutrients instead of chemical fertilizer.The experiment was divided into two treatments,with 0.5%potassium dihydrogen phosphate foliar fertilizer as control,seaweed organic mineral nutrient as foliar fertilizer as treatment,and a randomized block experiment was adopted,in which foliar fertilizer was applied 10 times in the whole growth period.The result showed that compared with chemical fertilizer,the application of seaweed organic mineral nutrients could increase the stem diameter and leaf area,reduce the internode length and plant height,and promote the strong seedling of tomato;It could improve the photosynthetic rate of tomato,increase the early yield by 7.0%and the total yield by 7.5%.The soluble sugar content of tomato increased by 12.8%;the disease indexes of tomato leaf mold and gray mold were 9.6 and 6.7 respectively,which reduced the infection of pathogenic bacteria.The application of seaweed organic mineral nutrient instead of chemical fertilizer in tomato production can not only reduce the application amount of chemical fertilizer,but also promote the growth of tomato at seedling stage,increase the yield of tomato and reduce the damage degree of disease.
