Embodiment 1

[0024] A rice humic acid foliar fertilizer containing alkaloids, the formula of which consists of the following components by weight (g): humic acid 4, aliphatic polyoxyethylene ether 20, alkaloids 0.1, 1% pachyphyllin emulsifiable concentrate 8, Urea 25, potassium dihydrogen phosphate 4, potassium nitrate 15, boric acid 10, zinc sulfate 5, manganese sulfate 5, sodium silicate 10.

[0025] The preparation method of the alkaloid rice humic acid foliar fertilizer comprises the following steps:

[0026] (1) Weigh zinc sulfate, manganese sulfate, boric acid, sodium silicate according to the formula, add appropriate amount of water and stir to dissolve to obtain a clear and transparent nutrient solution;

[0027] (2) Take humic acid by formula, add appropriate amount of water to dissolve, and obtain chelating agent solution;

[0028] (3) Mix the nutrient solution with the chelating agent solution, stir evenly, and carry out the chelating reaction to obtain the chelating reaction s...

Embodiment 2

[0030] A rice humic acid foliar fertilizer containing alkaloids, the formula of which is composed of the following components by weight (g): 5 humic acids, 25 aliphatic polyoxyethylene ethers, 0.5 alkaloids, 10 1% phalaetanin EC, Urea 27, potassium dihydrogen phosphate 5, potassium nitrate 16, boric acid 11.5, zinc sulfate 9, manganese sulfate 6.5, sodium silicate 13.

[0031] The preparation method is the same as in Example 1.

Embodiment 3

[0033] A rice humic acid foliar fertilizer containing alkaloids, the formula of which is composed of the following components by weight (g): 6 humic acids, 30 aliphatic polyoxyethylene ethers, 1 alkaloids, 1% phyllotine emulsifiable concentrate 15, Urea 30, potassium dihydrogen phosphate 6, potassium nitrate 20, boric acid 15, zinc sulfate 10, manganese sulfate 10, sodium silicate 15.

[0034] The preparation method is the same as in Example 1.

Abstract

The invention discloses a rice humic acid leaf fertilizer containing alkaloid, and a preparation method of the leaf fertilizer. The leaf fertilizer comprises the following components in parts by weight: 4-6 parts of humic acid, 20-30 parts of aliphatic polyoxyethylene ether, 0.1-1 part of alkaloid, 8-15 parts of 1% celastrus angulatus cream, 25-30 parts of urea, 4-6 parts of monopotassium phosphate, 15-20 parts of potassium nitrate, 10-15 parts of boric acid, 5-10 parts of zinc sulfate, 5-10 parts of manganese sulfate and 10-15 parts of sodium silicate. The rice humic acid leaf fertilizer can meet growth and development nutrients of rice; a plant source insecticide and a nutrient synergist are added, so that the immunity of the rice is improved, plant diseases and insect pests are effectively reduced, utilization ratios of the nutrients are increased, and effects of improving the quality of the rice and increasing the yield are achieved; and the rice humic acid leaf fertilizer is an ideal fertilizer for developing nuisanceless agriculture and soilless culture.

Description

technical field [0001] The invention relates to the field of foliar fertilizers, in particular to a rice humic acid foliar fertilizer containing alkaloids and a preparation method thereof. Background technique [0002] Fertilizer is a direct or indirect supplier of nutrients needed for crop growth, and has the function of improving soil properties and improving crop yield and quality. However, the effective absorption of ordinary fertilizer crops is low, and the fertilizer effect is slow. Large and excessive application of chemical fertilizers not only causes low soil fertility utilization rate, nutrient imbalance, soil compaction, but also causes environmental pollution, nutrient enrichment and other environmental problems. [0003] In field pest control, traditional chemical pesticides have the advantages of being fast, efficient, broad-spectrum and suitable for large-scale industrial production. However, as time goes by, the disadvantages of chemical pesticides are gradu...
