Compound fertilizer capable of improving crop sweetness and preparation method thereof

Abstract

The invention discloses a compound fertilizer capable of improving crop sweetness. The compound fertilizer comprises a macroelement fertilizer and a micromolecular water-soluble organic carbon complexoccupying 1% to 20% of the mass fraction of the macroelement fertilizer; the micromolecular water-soluble organic carbon complex comprises 500 to 2000 parts of micromolecular water-soluble organic carbon, 20 to 70 parts of boron, 5 to 15 parts of magnesium, 5 to 15 parts of molybdenum and 5 to 15 parts of calcium, wherein the micromolecular water-soluble organic carbon comprises 400 to 700 partsof liquid organic carbon, 700 to 1500 parts of sugar and 10 to 30 parts of amino acids. According to the fertilizer capable of improving crop sweetness, disclosed by the invention, by adopting the micromolecular water-soluble organic carbon complex comprising liquid organic carbon, sugar and amino acids, sufficient carbon sources can be provided for plant photosynthesis, and the formation of chlorophyll further can be promoted, so that the photosynthesis efficiency is improved. Moreover, the activity of enzyme participating sugar synthesis is improved in cooperation with assisted medium tracenutrient elements, and the accumulation of organic matters is quickened, the concentration of a substrate required for sugar synthesis is improved, and finally the sugar content of crops is improved.Therefore, the crops are relatively sweet in taste.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound fertilizer for improving the sweetness of crops and a preparation method thereof. Background technique [0002] Due to the geological structure, nutrient composition, and fertility of the soil, and the influence of some other natural conditions, the quality of the same agricultural products will be quite different. For example, some fruits are planted in the south and north. There are often problems such as the taste of the fruit is not sweet, and even the sour taste is severe. After careful research, the sweetness of plants (especially the sweetness of fruit plants) is mainly determined by the sugar content and composition of plants. Exogenous conditions such as light, water, nutrients, hormones, etc. can affect the formation of sugar. [0003] Based on the above situation, in order to increase the sugar content of plant fruits, measures such as increasi...

[0004] However, in the implementation of the above fertilizers, on the one hand, the use of the above-mentioned active auxin will affect the metabolism of the crop itself, destroy the growth balance of the crop itself, and is not conducive to the continuous results and harvest of planting; Not only are there great restrictions on the way of use, but there are also many active substances that cannot be applied together with compound fertilizers, otherwise they will reduce or lose their activity, which increases the cost of users and the complexity of application; in addition, these functional There is no pertinence or specificity in increasing the sugar content after the promotion ingredients are applied, and the cost increases greatly after use due to the high price
