Embodiment 1

[0020] Take the dried seaweed, remove impurities and foreign matter; soak it completely with 80% ethanol for 24 hours; concentrate the extract under reduced pressure to extract; freeze-dry the residue, then mix the extract and residue evenly, spray dry, and dry granulate to obtain "Edible" seaweed fertilizer.

[0021] Dilute the seaweed fertilizer prepared in this example with 1 / 1000 water, water the eggplant (the variety is "Hui Xiang" F1 CN013, Taiwan Nongyou Seedling Co., Ltd.), once every 20 days at the seedling stage, once every 10 days at the flowering stage and fruit setting stage , when the fruit is ripe, pick it.

[0022] 1) Investigate the dry weight of the leaves of the eggplant plants four weeks after planting, and measure the chlorophyll a and b contents of the leaves. Shown in Table 1, Table 1 is the statistical form of plant growth and development status of the present embodiment; As can be seen from Table 1, compared with the negative control group (no fertili...

Embodiment 2

[0029] Take fresh seaweed, remove impurities and foreign matter; soak it completely with 95% ethanol for 24 hours; concentrate the extract under reduced pressure to extract; freeze-dry the residue, then mix the extract and residue evenly, spray dry, and dry granulate to obtain "Edible" seaweed fertilizer.

[0030] The seaweed fertilizer prepared by the present embodiment is diluted with water 1 / 1000, and the capsicum (the kind is "Zhaojun" F1 CO007, Taiwan Nongyou Seedling Co., Ltd.) is watered, once every 20 days at the seedling stage, once every 10 days during the flowering stage and fruit setting stage, When the fruit is ripe, it is picked.

[0031] 1) Four weeks after planting, the dry weight of the leaves of the pepper plants was investigated, and the chlorophyll a and b contents of the leaves were measured. Shown in Table 6, Table 6 is the statistical form of plant growth and development status of the present embodiment; As can be seen from Table 6, the experimental gro...

Abstract

The invention discloses a preparation method of an algae fertilizer. The preparation method comprises the following steps: 1) removing impurities and exotic matters in algae; 2) completely soaking with ethanol for 24 hours; 3) concentrating lixivium at reduced pressure until extract is obtained; 4) carrying out freeze drying on residue; 5) evenly mixing the extract with the residue; and 6) carrying out spray drying, and carrying out dry granulation so as to obtain the algae fertilizer. The algae fertilizer prepared by using the method has specific advantages in the aspects of improving self-metabolism of a plant, adapting to external environment and providing nutrient substances, and is a natural green fertilizer which is simple in process and suitable for planting organic vegetables.

Description

technical field [0001] The invention relates to a preparation method of seaweed fertilizer. It belongs to the technical field of fertilizer production. Background technique [0002] In recent years, with the emergence of food safety incidents, the concept of "organic food" has quietly entered people's lives. According to the statistics of Nanjing Guohuan Organic Product Certification Center, the earliest and largest organic product inspection and certification organization in China, in 2008, the sales of my country’s exported organic food exceeded 500 million U.S. dollars, and the sales of domestic organic food are estimated to have exceeded 75 million U.S. dollars. billion yuan. According to the latest forecast of China Investment Consulting Industry Research Center, organic food is expected to account for 1-1.5% of the entire Chinese food market in the next 10 years. Today, when biotechnology, chemical fertilizer technology and pesticide technology have greatly increased...
