Description
Technical Field
The invention relates to the field of organic fertilizers, in particular to an organic fertilizer containing a camellia oleifera extract for promoting crop growth and a preparation method thereof.
Background
The oil tea is a local tree species with good economic and ecological benefits in China. The camellia seeds contain more than 60% of grease, and are rich in various vitamins, trace elements, sterol, squalene, carotene, polyphenol and other nutritional ingredients. Polyphenols are called as "group seven nutrients", have the functions of scavenging free radicals, inhibiting lipid peroxidation, enhancing the effects of other antioxidants and the like, can regulate the metabolic balance of free radicals in the body of a user, and prevent and treat related diseases, and therefore are attracting increasing attention of scholars. The high-efficiency extraction and analysis of the camellia oleifera polyphenol have important significance for comprehensively knowing polyphenol components in camellia oleifera seeds.
In the case of Fe deficiency in plants, the cause of the Fe deficiency is closely related to carbonate in high concentration in calcareous soil, for example, bicarbonate ions can cause the pH value of the soil to increase, so that the Fe concentration in the soil solution can be reduced. Under the condition of higher pH value, the adaptation mechanism of the plant to the stress of Fe deficiency can be inhibited to a certain extent, and simultaneously, HCO 3-in the plant body can cause the inactivation of Fe and finally the inactivation and the like.
If the soil contains a lot of organic fertilizers which are not decomposed, a lot of carbon dioxide is generated in the decomposition process of the organic fertilizers, and a lot of HCO 3-is generated, thereby having a serious influence on the Fe suppliability in the soil. If the phenomenon of Fe deficiency of crops occurs, the final yield is seriously influenced; if the urban greening trees or ornamental plants are lack of Fe, leaves of the plants become yellow, and the ornamental value of the plants is seriously influenced.
For a long time, people correct the phenomenon of iron deficiency of plants by spraying inorganic ferric salts such as ammonium ferrous sulfate, ferrous sulfate and the like on leaf surfaces, but the inorganic ferric salts are very easy to oxidize, finally generate precipitates and cannot be absorbed and utilized by plants. And the inorganic iron salt is not suitable for being mixed with other various pesticides and fertilizers.

The examples and comparative examples were added to the soil of iron-deficient apple trees (with yellow leaves) at a rate of 30 kg/acre, and the color change of the leaves and the growth state of the apple trees were observed, and the test values are shown in Table 1.
As can be seen from Table 1, the apple trees of the examples turned green and grew vigorously, while the apple trees of the comparative examples grew relatively poorly, the main reason for which is probably as follows, and the analysis of comparative example 1 shows that by adding Camellia oleifera extract, NH in fertilizer can be treated due to the fact that the extract is polyphenol4+Adsorbing and fixing to suppress NH4+Reduce the formation of nitrified nitrogen, thereby inhibitingHeterogeneity of the kinetic of the confined space nitrogen. Thus, the content of nitrate can be effectively reduced.
