Embodiment 1

[0019] The preparation of this foliar fertilizer composition commonly used of embodiment 1

[0020] The foliar fertilizer composition is made into water agent, emulsifiable concentrate, soluble liquid, water emulsion, microemulsion, suspending agent by adding solvent and auxiliary agent; it is made into powder, soluble powder, wettable powder, granule by adding known carrier and auxiliary agent Agents, water dispersible granules, microcapsules, tablets. This embodiment has introduced a kind of commonly used water preparation proportioning, but content of the present invention is not limited to this:

[0021] Dissolve 25g of sodium alginate oligosaccharide in 1L of water, then simultaneously add boric acid with a final mass concentration of 16%, borax with a final mass concentration of 12%, and finally add ammonium molybdate with a final mass concentration of 0.4% and 106g of amino acids with a content of 95% ( Mainly including threonine, aspartic acid, serine, glutamic acid, ...

Embodiment 2

[0023] Embodiment 2 uses this foliar fertilizer composition to improve the yield of rapeseed

[0024]Two treatments were designed in the experiment: treatment 1, the foliar fertilizer composition of Example 1 was diluted 500 times, and sprayed once at the bolting stage + full flowering stage of rape, 30 kg per mu; treatment 2 was not sprayed (control). Each treatment was repeated three times and arranged randomly. The length of the plot was 13.52m, the width was 7.4m, and the distance between rows and holes was 0.74m×0.26m. Each plot was planted with 11 rows, 583 holes, double planting, and 7226 plants per mu. The spraying time was carried out on March 7th and March 25th, 2012, using a Gongnong 16 manual sprayer, and the leaves were wet without dripping water. The experiment investigated each treatment during the maturity stage of rapeseed. Each plot is sampled at 4 points, and 50 plants are investigated at each point. The survey indicators include total silique trees, per si...

Embodiment 3

[0029] Embodiment 3 uses this foliage fertilizer composition to improve cherry yield

[0030] Utilize three different kinds of cherries of Hongdeng, Pioneer and Longguan to carry out yield experiments, dilute the foliar fertilizer composition of Example 1 by 500 times, spray before the snow on April 12, 2012, apply 200kg of medicinal solution per mu, investigate The yields of 3 cherry varieties, the results show that the foliar fertilizer composition has a better yield-increasing effect on cherries, and the specific results are shown in Table 3 below.

[0031] Table 3. Use the impact of this foliar fertilizer composition on cherry yield

Abstract

The invention discloses a leaf fertilizer composition comprising sodium alginate oligosaccharide, which is characterized in that the composition comprises sodium alginate oligosaccharide, amino acid and microelements that can promote plant growth significantly, wherein sodium alginate oligosaccharide is also known as sodium alginate, sea-tangle glue and algin, is natural polysaccharide carbohydrate extracted from sea tangle, and is a copolymer comprising a-L-mannuronic acid (M), b-D-guluronic acid (G) connected with a-L-mannuronic acid (M) by 1,4-glycosidic bond, and different GGGMMM fragments; a molecular formula is (C6H7O6Na)n; the degree of polymerization is 2-10; the uronic acid constitution M/G is equal to 7:3; the uronic acid content is greater than 90%, and is 2-3% of the total content; the content of a microelement leaf fertilizer is 2-20%; and the microelement leaf fertilizer comprises at least two of sulfur, boron, ferrum, manganese, copper, zinc and molybdenum. The composition is mainly applicable to industrial crops, fruit and vegetable crops, grain crops, economic trees, flowers, lawns and the like.

Description

technical field [0001] The invention relates to the physiological metabolism of plants, in particular to the application of amino acids, sodium alginate oligosaccharides and trace elements as main active substances in plant growth promotion. Background technique [0002] Traditional chemical fertilizers have a single fertilizer effect and serious pollution. Long-term use will damage the soil structure, while synthetic plant growth regulators will easily cause table pollution and lead to a decline in the quality of agricultural products. After my country's accession to WTO, food safety has become a key factor affecting the competitiveness of agriculture and food industry in the international market. The development and application of safe production technology for pollution-free agricultural products is imminent. Amino acids and marine oligosaccharides are natural extracts, which can make up for the shortcomings of traditional fertilizers and synthetic plant growth regulators...
