Last Updated: 2024/11/23, Spinach nitrogen deficiency: the leaf color is light green, the basal leaf (old piece) turns yellow, gradually develops upward, and turns brown when dry. The plant is short, the branch (tiller) is few, appear the phenomenon of premature senescence. Control methods: apply sufficient base fertilizer, 2000-3000 kg per mu of rotten fertilizer, 30-35 kg of phosphate fertilizer and 10-15 kg of potash fertilizer. 2 Murray.

Spinach nitrogen deficiency: leaf color light green, basal leaves (old) yellow, gradually upward development, brown when dry. Plant short, branches (tillers) less, premature aging phenomenon. Control method: apply enough base fertilizer, apply decomposed fertilizer 2000-3000 kg per mu, phosphorus fertilizer 30-35 kg, potassium fertilizer 10-15 kg. 2-3 When the leaves are true, combine with thinning and topdressing once, and apply urea 7.5-10 kg per mu. 6-7 15-20 kg urea per mu at leaf stage. Spinach winter cultivation, after spring temperature stability (no ice), such as topsoil drought, seedling heart leaves green, to early irrigation return green water. Autumn spinach, 2 leaf stage combined with thinning and topdressing once, 4-5 leaf watering topdressing, mainly available nitrogen fertilizer. During spinach growth to keep the soil moist, in case of drought to timely irrigation or combined with topdressing nitrogen fertilizer.
