The Effects of Using Fish Protein Liquid Fertilizer on Peach Trees

Benefits of using fish protein liquid fertilizer on peach trees: optimizing soil structure, increasing fruit set rates, and enhancing physiological functions and stress resistance.

Optimizing Soil Structure
When applied to the soil, fish protein liquid fertilizer provides organic matter (such as fish protein) that serves as a substrate for the rapid proliferation of beneficial microorganisms; their activity can increase more than tenfold. This optimizes soil structure and significantly improves water and nutrient retention. Continuous use over one or more years encourages earthworm populations, resulting in loose, fertile soil. It also converts previously unavailable (slow-release) nutrient forms into readily available forms, thereby boosting soil fertility.

Increasing Fruit Set Rates
Fish protein promotes balanced nutrient uptake, preventing deficiencies and resulting in deep green foliage and sturdy stems. It enhances photosynthesis, accelerates flowering and fruit set, and ensures robust blossoms. This leads to significantly higher fruit set rates, rapid fruit expansion, and excellent coloration, ultimately increasing yield and improving fruit quality. There is a marked accumulation of nutrients such as proteins, sugars, and vitamins.

Enhancing Physiological Functions and Stress Resistance
Fish protein water-soluble fertilizer contains abundant fish protein amino acids and various natural bioactive substances. These effectively stabilize plant cells, promote thicker leaves with tightly arranged surface cells, and boost physiological functions. It enhances resistance to waterlogging and creates a barrier against pathogen and pest invasion. Additionally, it lowers the freezing point of plant sap (dropping it below 0°C), thereby improving cold and frost resistance.

Fish protein water-soluble fertilizer has a wide range of applications, including: seedling strengthening, unlocking plant potential, and addressing issues such as stunted or yellowing seedlings, poor rooting, phytotoxicity, frost damage, heat stress, sparse flowering/fruiting, flower and fruit drop, poor fruit expansion, discoloration, and lack of sweetness or flavor.
