preparation example Construction

[0044] In order to further explain the preparation method of the fertilizer efficiency-enhancing factor, the present invention further makes a more detailed example.

[0045] Scrape a ring of bacteria from the preservation slope of CSF-1 strain and inoculate it into a 300ml Erlenmeyer flask containing 20ml seed medium. Incubate for 14 hours at 37° C. on a shaker with a rotation speed of 200 rpm. Then inoculate it into a 1000ml Erlenmeyer flask containing 150ml of fermentation medium at a ratio of 1:100 and cultivate it for 12-16 hours to make a bacterial suspension (solid-state fermentation seed solution) for later use.

[0046] Composition of seed medium and fermentation medium (based on 1000mL medium): maltose 40g, soluble starch 40g, glutamic acid 20g, MgSO 4 0.5g, KCl 0.5g, KH 2 PO 4 1g, FeSO 4 ·7H 2 O0.15g, MnSO 4 0.005g, CuSO 4 ·5H 2 O 0.00016g, yeast extract 1g, pH 7.0-7.2. The above-mentioned culture medium was at 1.0×10 5 Pa, sterilize at 121°C for 20 min...

Embodiment 1

[0054] There is a white or light brown film on the surface of the downstream substrate after solid fermentation, thicker mucus can be seen and filaments can be drawn out when stirred with a needle, suggesting that a high molecular weight polymer similar to γ-polyglutamic acid has been synthesized by fermentation. Detecting its productive rate is 40-60g / kg (material), molecular weight is between 40-150kDa.

[0055] The fermentation substrate was dried, weighed 0.1 g, and extracted with 4 ml of pure water (2.5% concentration). After the insoluble particles were precipitated, the supernatant (leaching solution) was taken, and the concentration of the supernatant was 0.87%. The supernatant was tested for flocculation of soil colloids.

[0056] Prepare 2.5% polyaluminum chloride solution as a control, and compare the flocculation effect of the two on soil colloid.

[0057] The soil was dried and pulverized, and 0.4 g was weighed and added to 40 ml of pure water to make a suspensio...

Embodiment 2

[0063] To prepare the efficiency-enhancing factor of 1 kg of composite bio-based efficiency-enhancing urea, the weight ratio of soybean meal-corn germ meal-attapulgite in the solid fermentation medium used is 60-20-20.

[0064] Take 6 acrylic tubes with a length of 490 mm and an inner diameter of 14 mm. Tubes No. 1, 2 and 3 are used as the control group, and tubes No. 4, 5 and 6 are used as the experimental group. 45g of 80-100 mesh quartz sand (height about 200mm) was filled in the 6 tubes first, the control group was filled with a mixture of 0.1g urea and 1g quartz sand, and finally covered with 10g quartz sand; while the experimental group was filled with 0.1g urea and 0.01g efficiency-enhancing factor Mix with 1g of quartz sand, and finally cover with 10g of quartz sand.

[0065] The 6 tubes are vertically placed on the support, and water is leached from above, and the water feeding rate is 0.1ml / min. Collect once every 30 minutes, collect the filtrate in three time perio...

Abstract

The present invention discloses an effect enhancing method of a compound biobased fertilizer and a fertilizer with an enhanced effect. The key is to introduce an effect enhancing factor of the compound biobased fertilizer to the fertilizer. The effect enhancing factor refers to all matrixes downstream derived from residues of production of agricultural products and solid state fermentation of active soil materials, and comprises a biopolymer polymer gamma-polyglutamic acid and a broad spectrum of plant nutrients derived from a biological fermentation process of plants. The present invention is capable of not only reducing or controlling fertilizer nutrients loss, but also improving the plant rhizosphere soil ecological environment, thus promoting balanced nutrient absorption by plants. In the case of the reduced fertilizer application amount, crop biomass can be increased and crop quality can be improved. The present invention further discloses a preparation method of the fertilizer effect enhancing factor, a compound biobased fertilizer with the enhanced effect and having the fertilizer effect enhancing factor and an application of the compound biomass fertilizer with the enhanced effect.

Description

technical field [0001] The present invention relates to the technical field of chemical fertilizers, in particular to a chemical fertilizer efficiency-enhancing factor in this field, a manufacturing method of the chemical fertilizer efficiency-enhancing factor, an application of the chemical fertilizer efficiency-enhancing factor in chemical fertilizers, and a chemical fertilizer with the chemical efficiency-enhancing factor Composite bio-based efficiency-enhancing fertilizer and a preparation method of the composite bio-based efficiency-enhancing fertilizer. Background technique [0002] Among the various factors of grain production increase, the contribution of chemical fertilizers accounts for about 40%. However, the current utilization rate of fertilizer nitrogen is only 30%-35%, most of which are released to the environment through seepage, runoff or volatilization, resulting in three-dimensional intersections from underground (water), surface (water, soil) to air (atmo...
