Cucumber Full-Process Nutritional Package

Fertilizer types and application rates: 3–4 cubic meters of farmyard manure, or 100–200 kg per mu of Nongda Ecological Fertilizer (a three-in-one bio-organic fertilizer), plus 10 kg per mu of Xianxian Minggenbao, and 20 kg per mu of high‑calcium potassium‑magnesium fertilizer; additionally, apply 80–100 kg per mu of Nongda Heisongtu series products, such as active humic acid formulations like 15‑15‑15S or 17‑17‑17S.

         Application method: Apply the bio‑fertilizer as a broadcast dressing before tillage, and incorporate it into the soil in bands or at planting sites.

         Performance effect: Balances nutrients and loosens the soil, creating an optimal growing environment for root development; robust roots ensure deep penetration and lush foliage. Leaves exhibit strong physiological functions and enhanced stress resistance. 。

Topdressing during the seedling stage

Fertilizer type and application rate: The Black Pine Soil Series features an active humic acid formulation with high nitrogen content, applied at a rate of 25–30 kg per mu.

Topdressing during the fruit-swelling stage

Fertilizer type and application rate: Apply alternately: Nongda Heisongtu nitrate fertilizer 15-5-20S at 20–30 kg per mu, or Nongda Shuirun Tu humic acid water-soluble fertilizer 18-0-22/16-6-36, at 5–8 kg per mu; in the mid-to-late growth stage, apply Shuirun Tu bio‑microbial water‑soluble fertilizer 20-20-20.

Application method: Typically, a single fertilizer application is required after each harvest; the recommended formulation is moderate nitrogen, low phosphorus, and high potassium. When combined with drip irrigation for fertilization, this can reduce chemical fertilizer use by 20%. In contrast, with flood irrigation, each fertilization event necessitates an increase of 10%–20% in fertilizer application rates.

Performance effect: The plants exhibit vigorous growth, with balanced vegetative and reproductive development, strong disease resistance, rapid cucumber growth, high yields, excellent fruit quality, robust tolerance to continuous cropping, and resistance to premature senescence.

Fertilizer type and application rate: During the young fruit enlargement stage, apply foliar fertilizers such as Nongdazhuang Keli, Hezefeng, and Huangjinlu alternately every 7–10 days.

Application method: Foliar spray;

Performance effect: Enhance leaf photosynthesis, replenish nutrients, and prevent premature senescence.

Notes: In areas where nematodes are prevalent, apply 10 kilograms of the ecological fertilizer “Xianxian Genbao” as a soil drench one month before the annual outbreak. Fertilization practices, methods, and application rates should be tailored to local conditions or carried out under the guidance of the local agricultural extension services.
