通过开展番茄生物有机肥培肥定量化用量试验研究,综合评价确定合理用量,提升土壤生物活性。试验结果表明:通过对亩施1、2、3 t生物有机肥和传统商品有机肥进行比较,表明亩施2 t生物有机肥,不仅可以增产24.75%,还能提高果实品质,提高番茄Vc含量34.54%,降低硝酸盐含量6.63%,同时提升土壤有机质5.44%、有效磷、速效钾含量分别提高16.03%和5.10%,以及提升土壤微生物生物量碳13.95%、脲酶活性和蔗糖酶活性分别提高12.74%和40.42%。因此推荐在番茄等茄果类蔬菜上亩施加生物有机肥2 t。
By carrying out experiments on the quantification of tomato bio-organic fertilizers and fertilizers, a comprehensive evaluation was conducted to determine the reasonable dosage and to enhance the bioactivity of soil. The results showed that: Compared with the organic fertilizers of 1,2,3 t bio-organic fertilizer and traditional commercial organic manure of Mushi, it showed that applying 2 t bio-organic fertilizer could not only increase yield by 24.75%, but also improve fruit quality and increase Vc content of tomato 34.54%, nitrate content 6.63%, soil organic matter 5.44%, available phosphorus and potassium increased by 16.03% and 5.10%, and soil microbial biomass carbon increased by 13.95% and urease activity and invertase activity increased by 12.74 % And 40.42%. Therefore, it is recommended to apply bio-organic fertilizer 2 mu to solanaceous vegetables such as tomato.
