Embodiment 1

[0025] An organic fertilizer for pine needles is an emulsifiable concentrate or water-soluble organic fertilizer or granular fertilizer made from the organic solvent extract of pine needles as an active ingredient. Its preparation method is as follows: firstly, pick off the fresh and mature pine needles, remove the withered yellow needles, place them in a ventilated place with a sieve to air dry, pack and store them in a dry, cool and ventilated warehouse for later use, crush the air-dried pine needles for 20- 60-mesh sieve, extract the organic matter with ethanol with a concentration of 85-90%, obtain the extract, set aside, and then use one of the following three methods to prepare organic fertilizer:

[0026] Method 1. Extract the obtained extract with 85% ethanol to make an emulsifiable concentrate with a concentration of 29%. The specific preparation method of the dosage form of emulsifiable concentrate is common knowledge in the art, and will not be described in detail h...

Abstract

The present invention relates to an organic fertilizer, a preparation method therefor and a use thereof. A pine needle organic fertilizer is emulsifiable concentrate or water-soluble organic fertilizer or granular fertilizer which contains an organic solvent extract of pine needles as an effective component. The fertilizer is applied before fruit trees flower, the quality in the flowering stage and the quality of fruits can be improved, the dried matter content is increased, the sugar content is increased, and early maturing and late harvesting are promoted. The fertilizer can be used for treating citrus tristeza viruses. The fertilizer is used for reducing the root-rot disease and defoliator pest in the seedling stage of vegetables. The fertilizer is used before tea sprouting, the number of sprouts is increased, tender shoots and tender leaves become thicker, and the yield and the quality of the tea leaves are remarkably improved.

Description

technical field [0001] The invention relates to an organic fertilizer, a preparation method thereof, and an application thereof. Background technique [0002] On March 4, 2015, a news report from the National Committee of the Chinese People's Political Consultative Conference stated that my country's arable land area only accounts for less than 8% of the world's arable land area, but the use of chemical fertilizers and pesticides accounts for one-third of the world's total. [0003] On February 23, 2010, the internationally renowned journal "Science" published an article pointing out that due to the excessive use of chemical fertilizers in China in the past 30 years, chemical fertilizers are acidifying China's soil. China has been striving to feed 1 / 5 of the world's population with 7% of the earth's arable land. The article published in "Science" pointed out that the pH value of the soil is crucial for plant growth. Most crops will thrive in neutral—that is, a pH of 7—or s...
