Embodiment 2

[0026] Embodiment 2 field test 1

[0027] The cabbage was used as the test material to carry out the field experiment. The area of ​​each plot was equal to 20 square meters, and each group had 3 repetitions. The control group was sprayed with clear water, and the test groups 1-10 were sprayed with an aqueous fertilizer solution at a concentration of 200 mg / kg, and the dosage was based on the dripping water from the leaves. The fertilizer formulations of test groups 1-10 are shown in Table 3.

[0035] The cabbage was used as the test material to carry out the field experiment. The area of ​​each plot was equal to 20 square meters, and each group had 3 repetitions. The control group was sprayed with clear water, and the test groups 1 to 4 were sprayed with aqueous fertilizer solution at a concentration of 300 mg / kg, and the dosage was based on the dripping water from the leaves. The fertilizer formulations of test groups 1-4 are shown in Table 5.

Abstract

The invention discloses a composition capable of reducing an oxalic acid content in vegetables, which mainly contains dimethyl sulfoxide and methionine. The composition can effectively reduce accumulation of oxalic acid in vegetables, thereby reducing the oxalic acid content in the vegetables. Proved in potted tests, the composition can reduce more than 6.6% of the oxalic acid content in the vegetables, preferably 20-50% of the oxalic acid content in the vegetables, and proved in field experiments, the composition can reduce 10% of the oxalic acid content in the vegetables in probability exceeding 90%. The composition can be mixed with water to preparing a liquid foliar fertilizer. The composition can also be used by complex formulation with a common fertilizer.

Description

technical field [0001] The invention relates to a vegetable fertilizer, in particular to a composition capable of reducing the oxalic acid content of vegetables. Background technique [0002] Oxalic acid is ubiquitous in plants. According to its solubility, it is divided into water-soluble oxalic acid and insoluble oxalic acid. Insoluble oxalic acid will reduce the availability of some mineral elements in vegetables, such as calcium, without affecting the availability of calcium in the human body. Sex; water-soluble oxalic acid can combine with many mineral elements in food to form insoluble salts, causing the lack of mineral elements such as Ca, Fe, Mg, Cu, etc. in the human body, and can also increase the secretion of urinary oxalic acid, causing urinary system stones, such as kidney stones At present, the main component of more than 70% of kidney stones is calcium oxalate. [0003] Different types of nitrogen fertilizers had significant effects on oxalic acid content. P...
