Pine needle organic fertilizer and preparation method and application thereof

Abstract

The invention relates to an organic fertilizer and relates to a preparation method and application thereof. According to a pine needle organic fertilizer, an organic solvent extract of pine needles serves as an effective component and is prepared into emulsifiable concentrate or water-soluble organic fertilizer or granular fertilizer. The fertilizer is applied before fruit trees flower, the quality in the flowering stage can be improved, the quality of fruits is 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 in the seedling stage of vegetables and used for reducing the root-rot disease and defoliator pest. The fertilizer is used before tea sprouting, the number of sprouts is increased, tender shoots become thicker, tender leaves become thicker, the yield of tea leaves is obviously increased, and the quality of the tea leaves is 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...

Moreover, the PH value of the soil will drop, and the diseases and pests it brings will hinder the growth of plants, and the strong acid environment will also accelerate the leaching of toxic metals to the surrounding water.
