Problems solved by technology

[0007] (1) The nutrient supply is unreasonable. In addition to the nitrogen, phosphorus, and potassium macronutrients that meet the needs of corn, the ratio of medium and trace elements provided is unreasonable, and the utilization rate of medium and trace elements chelated by inorganic state or strong chelating agent is low, and it is difficult to truly develop should have effect;
[0008] (2) corn is a wide-leaf plant, and leaf chlorophyll content is an important factor determining dry matter accumulation and yield of corn. In the prior art, there are fewer functional designs for improving corn leaf chlorophyll content in a targeted manner;
[0009] (3) Maize planting in my country is prone to environmental stress (drought, flood, freezing), and the existing fertilizers are not effectively designed to improve the resistance of corn to the above stresses.

Abstract

The invention discloses a functional synergist for a fertilizer. The functional synergist comprises a component A and a component B; the component A comprises the following raw materials in parts by mass: 120-150 parts of a sugar alcohol solution, 50-80 parts of a polypeptide composition, 10-20 parts of a boron fertilizer, 10-20 parts of a zinc fertilizer, 2-10 parts of other medium trace element fertilizers and 20-100 parts of deionized water; the component B is a curing agent; the mass ratio of the component A to the component B is (23): 1. The invention also discloses application of the fertilizer functional synergist in fertilizers, including fertilizer coating, seed coating or foliage spraying. The fertilizer functional synergist provided by the invention can effectively improve the stress resistance and chlorophyll synthesis in the plant growth period, and improve the nutrient utilization rate of plants, thereby effectively improving the yield and quality of the plants.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer functional synergist and its application. Background technique [0002] Corn is one of the three major food crops in my country. As a crop with both grain, economy and feed, it has a huge impact on the development of the entire national economy. Corn needs to absorb a variety of mineral nutrients from the soil during its growth period. According to reports, 2.5 kg of pure nitrogen, 1.2 kg of phosphorus pentoxide, and 2.0 kg of potassium oxide must be absorbed from the soil for every 100 kg of corn kernels produced. In addition, Trace elements such as zinc, boron, calcium, magnesium, iron, manganese, copper, and molybdenum are also needed. Corn is particularly sensitive to zinc and boron deficiency. If zinc is deficient in the seedling stage of corn, "white seedlings" will appear, starting at the 3rd to 5th leaf stage. Symptoms, the young leaves are light yellow ...
