Embodiment 1

[0029] Embodiment 1 Foliar fertilizer preparation method:

[0030] (1) The zinc sulfate, manganese sulfate, magnesium sulfate and ferrous sulfate that were weighed earlier are fully dissolved in metered water, and the pH is adjusted to 5.5 with sulfuric acid to make a nutrient solution;

[0031] (2) take by weighing EDTA and citric acid by formula, add and make chelating agent solution in metering water;

[0032] (3) Mix the nutrient solution and the chelating agent solution, adjust the pH value to 5.5, stir at 50° C., and carry out the chelating reaction for 1 hour;

[0033] (4) Add urea, boric acid, potassium dihydrogen phosphate, potassium fulvic acid, sodium nitrophenolate, salicylic acid and surfactants weighed according to the formula into the chelated reaction solution to make foliage fertilizer.

Embodiment 2

[0034] Example 2 Application method and application effect for 4-year-old Asarum

[0035]The prepared foliar fertilizer, according to the above-mentioned foliar fertilizer spraying method, during late May to late August, select sunny days to spray on the 4-year-old Asarum foliage at 16:00-17:00 in the afternoon. Investigate the field growth status of 4 years old asarum (leaf length, leaf width, petiole thick measurement method is to choose 30 leaves respectively, measure its leaf length, leaf width with meter ruler, measure petiole thick with vernier caliper, get the average value), Net photosynthetic rate (note: the measuring method of net photosynthetic rate is: select 3 strains of asarum, under the situation of not taking shade net, measure its net photosynthetic rate (contrast) at 14:00 before spraying foliage fertilizer, spray The next day after applying foliar fertilizer, measure the net photosynthetic rate) and the number of spores and the number of fibrous roots of thi...

Embodiment 3

[0037] Example 3: Application method for 5-year-old Asarum, and application effect

[0038] According to the preparation method of the above-mentioned foliar fertilizer, the foliar fertilizer is made. According to the above method of foliar fertilizer spraying, choose a sunny day to spray on the 5-year-old Asarum foliage at 16:00-17:00 in the afternoon, and spray 5 times in total. Investigate the field growth status of 5-year-old asari (leaf length, leaf width, petiole thick measurement method is to choose 30 leaves respectively, measure its leaf length, leaf width with meter ruler, measure petiole thick with vernier caliper, get the average value), and yield and volatile oil content. After spraying foliage fertilizer, the color of leaves of 5-year-old Asarum was darker than that of the control, and the leaves were larger than that of the control. The ability to resist strong light, high temperature and drought is enhanced. Under the sunny high temperature conditions in mid-...

Abstract

The invention provides a special foliar fertilizer for asarum and its application method. According to the law of growth, development and yield increase of Asarum, in the critical 3 years of the growth of Asarum, giving sufficient nutrients can effectively promote the full growth of Asarum, and accordingly, the present invention provides a water-soluble nutrition of Asarum And functional foliar fertilizer, the foliar fertilizer selects urea, potassium dihydrogen phosphate as quick-acting nitrogen, phosphorus and potassium; magnesium sulfate, ferrous sulfate, boric acid, manganese sulfate, zinc sulfate provide medium and trace elements; fulvic acid Potassium, sodium nitrophenolate, and salicylic acid were used as growth regulators; citric acid, disodium edetate, and Tween-80 were used as auxiliary agents. The combination of these reagents makes each component produce a synergistic effect, thereby effectively promoting the growth and nutrient absorption of the root system of the asarum, protecting the photosynthetic organs of the asarum, and promoting the photosynthesis of the asarum.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a foliar fertilizer suitable for Asarum asarum and its application method Background technique [0002] Asarum is a large number of authentic Chinese medicinal materials in Northeast China, with a large planting area in Northeast China. It is the authentic product of Asarum medicinal materials in the Pharmacopoeia of the People's Republic of China (2015 Edition), and its roots are used as medicine. In addition to being used for clinical treatment of diseases such as wind-cold cold, headache, toothache, arthralgia, runny nose, cold drink, cough, and tongue sores, it can also be used as an industrial raw material to make termites with high efficiency, low toxicity, and no pollution. Control agents, mosquito repellants, plant pesticides, etc., so its domestic and foreign markets are very broad. [0003] Asarum is a perennial shade plant, it takes 3-4 years from transpla...
