This invention discloses a
nutrient adjuvant for increasing sugarcane yield and its preparation method, comprising the following steps: Making
Enzyme 1: Collect
protein casing waste, add a pre-set fermenting agent to the
protein casing waste and ferment for 6-10 hours, sterilize, cool and filter; the filtrate is
Enzyme 1. Making
Enzyme 2: Take
Imperata cylindrica root, dilute with water and pulp, separate the pulp and residue, take the pulp, add PBS
mother liquor to the pulp and then inoculate with bacterial
powder, seal and ferment for 40-52 hours to obtain Enzyme 2. Making Enzyme 3: Take
Mesona chinensis and
alcohol solution, shake repeatedly for 5-8 hours, filter, dilute the filtrate 10-20 times, then inoculate with bacterial solution, maintaining an
aeration rate of 0.08 m³ / h. 3 / (m 3 ·min)-0.15m 3 / (m 3 The mixture is fermented aerobically for 4-6 days (min), filtered, and the pH of the filtrate is adjusted to 7.0-8.0 to obtain
enzyme 3. Enzyme 1,
enzyme 2, and
enzyme 3 are mixed to prepare a
nutrient adjuvant for increasing sugarcane yield. Compared with the prior art, this invention prepares a
nutrient adjuvant containing high levels of acid-soluble proteins, flavonoids, organic acids and their salts, and effective active
bacteria. This nutrient adjuvant promotes the development of sugarcane roots, increases sugarcane leaf area, improves the rate of
photosynthesis, and increases sugarcane yield; it also improves soil degradation and nutrient imbalance caused by continuous sugarcane
cropping, and restores
soil ecology and
fertility.
