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
