Embodiment example 1

[0014] Implementation case 1: a kind of method that utilizes lumbrokinase to prepare foliar fertilizer provided by the present invention comprises the following steps:

[0015] (1) Extraction of crude product of lumbrokinase: take a certain amount of fresh and live earthworms, put them in clear water, take them out and put them in the extraction bed after 24 hours, and spray 1000ml of induced enzymes in mist form from top to bottom per minute to achieve stimulation Earthworms secrete a large amount of enzyme active substances, and then centrifuge the enzyme active substances at a speed of 6000 rpm for 10 minutes, take the supernatant, and filter by gel filtration chromatography to obtain the lumbrokinase stock solution.

[0016] (2) Fermentation liquid extraction: add EM bacterial agent to vermicompost, evenly sprinkle brown sugar water with a concentration of 10%, so that the water content of vermicompost reaches 60%-70%, put it in a large container, seal it well, and keep the...

Abstract

The invention discloses a method for preparing a leaf fertilizer from a lumbrokinase. The method comprises the step of mixing lumbrokinase, an earthworm cast fermentation solution, a plant ash solution, urea and dipotassium phosphate according to the ratio of 50:45:1:0.3:3 to prepare the leaf fertilizer. The method is simple in preparation and relatively low in cost; and the earthworm cast fermentation solution contains abundant nutrient substances and a great number of active substances such as beneficial microorganisms and organic matters as well as macroelements and microelements, can be used for improving the adverse-resistant characteristics such has cold resistance and drought resistance and the absorption capacity of crops to nutrients and can also be used for accelerating the absorption of plant leaves to nutrients, increasing the yield of crops and improving the quality of the crops.

Description

technical field [0001] The invention relates to a method for preparing foliage fertilizer by using lumbrokinase. Background technique [0002] Foliar fertilization has become one of the important high-yield cultivation management measures. Foliar fertilizer is a supplement for plants to absorb nutrients to make up for the lack of nutrients absorbed by roots. In the process of crop growth, crops have shown some nutrient deficiency. When trace elements are applied to the soil, nutrients are often easily fixed and not easily absorbed by plants. The effectiveness is low and it takes a certain amount of time. deficiency symptoms. At this time, foliar fertilization is used, and nutrients can enter the plant directly from the leaves to participate in the metabolism of the body, and solve the problem of nutrient deficiency, which is faster and more effective than soil fertilization. [0003] At present, most fertilizer products have low nutrient content and high content of ineffec...
