番茄高产增收,除选用优良品种、培育壮苗、深耕晒土、重施基肥、合理密植、科学追肥,防治病虫外,在生长期进行叶面喷肥、补充养分,增强抗病抗旱能力,能使番茄增产10～20％以上。 1.喷硫酸锌 番茄生长期喷施硫酸锌,可以促进生根、缓苗、开花结果,减少落花落果,并可防止旱害。番茄喷施硫酸锌以苗期效果为好,若在苗期、花期各喷一次,效果更佳。 2.喷硫酸亚铁 石灰性土壤、过量施用石灰的酸性土壤中铁的含量虽不少,但能被番茄吸收利用的有效铁含量极少, In addition to the selection of good varieties, nurturing strong seedlings, cultivating sunburden, re-basing fertilizer, close planting density, scientific top dressing, prevention and control of pests and diseases, in the growing period of foliar fertilizer, nutrient replenishment, enhance disease and drought tolerance, Can increase tomato yield 10 to 20% or more. 1. Spraying Zinc Sulfate Zinc sulfate sprayed growth stage can promote rooting, Huanmiao, flowering and reduce the loss of flowers, and prevent drought damage. Spraying tomato with zinc sulfate to seedling effect is good, if the seedling, florescence spray, the better. 2. Spraying ferrous sulphate soil, the iron content of acid soil overdosing lime although not less, but can be absorbed and utilized by tomato effective iron content is very small,
