Fertilizer for improving high temperature and cloudy or rainy day adaptability of plants

Abstract

The invention provides a fertilizer for improving the high temperature and cloudy or rainy day adaptability of plants. Main components of the fertilizer comprise 1-20wt% of elemental nitrogen, 1-20wt% of elemental phosphorus, 1-20wt% of elemental potassium, 40-65wt% of an amino acid fermentation liquid, 1-8wt% of trace elements, 1-5wt% of a plant nutrition regulator and 1-5wt% of a microbial agent. The trace elements comprise 0.1-1% of elemental zinc, 0.8-5% of elemental magnesium and 0.1-2% of elemental manganese. The amino acid fermentation liquid adopted as a main raw material is rich in micro-molecular organic matters, amino acids, plant regulators and other active substances and trace elements, so when crops encounter high temperature, high humidity, cloudy low light and other adversity stress, roots, stems and leaves can rapidly absorb the active substances to supplement carbon sources needed by breathing, reinforce the fixation ability of carbon dioxide and promote photosynthesis. Synergism of the active substances and beneficial microbes makes growth of harmful pathogens in soil be effectively inhibited, soil borne diseases be prevented and treated, damages of the adversity stress to the crops be alleviated and yield reduction and loss of the crops be alleviated.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a fertilizer that can improve the adaptability of plants in high-temperature and rainy days. Background technique [0002] The weather in South China, especially Guangdong, is hot from May to July, and there is a lot of rain. Rainwater accumulates in low-lying areas, which is easy to cause waterlogging. The high temperature and high humidity weather leads to poor growth of crops and frequent occurrence of soil-borne diseases. The photosynthesis of crops is hindered in rainy days, and carbon nutrition is insufficient, which aggravates crop root rot and leaf yellowing, crop growth stagnation, growth period shortening, and yield and quality decline. At present, the market mainly controls diseases by spraying pesticides to alleviate the impact of high temperature and rainy days on crops. However, doing so will cause the soil to be polluted, and the crops will contain pesticide r...

However, doing so will cause the soil to be polluted, and the crops will contain pesticide residues, which will affect human health and is not conducive to environmental protection

[0003] As a high-concentration organic wastewater, the amino acid fermentation liquid is rich in nitrogen, phosphorus, potassium, organic matter and other nutrients. Because it will cause eutrophication in the water body, it needs to be discharged after physical and chemical purification treatment, which will inevitably bring costs. a substantial increase in
