Sustained release microelement fertilizer for controlling plant diseases and insect pests

Abstract

The invention relates to sustained release microelement fertilizer for controlling plant diseases and insect pests. The sustained release microelement fertilizer comprises 50 to 80 weight parts of acrylic acid, 30 to 50 weight parts of natural dried sheep manure, 60 to 90 weight parts of urea, 10 to 15 weight parts of diammonium hydrogen phosphate, 0.5 to 1.2 weight parts of calcium, 0.2 to 1.5 weigh parts of magnesium, 0.4 to 0.8 weight part of ferrum, 0.1 to 0.3 weight part of boron, 0.05 to 0.25 weight part of zinc, 0.25 to 0.4 weight part of molybdenum, 0.07 to 0.09 weight part of streptomycin, 0.1 to 0.2 weight part of amino acid and 0.7 to 0.9 weight part of alkyl sodium sulfonate. The sustained release microelement fertilizer has the advantages of high water retention capacity and biological and chemical stability, complete function of adjusting the growth and development of crop, good effect, environment-friendliness, and effect of controlling plant diseases and insect pests, and cost is reduced.

Description

technical field [0001] The invention belongs to the field of superabsorbent resins, and in particular relates to a slow-release micro-fertilizer suitable for preventing pests and diseases. Background technique [0002] Trace elements zinc, boron, copper, manganese, molybdenum, iron, etc., as essential elements for plant nutrition, entered the agricultural production system in the form of fertilizers. At the beginning, it was applied to large-scale production, which is an emerging field and has developed rapidly. In the past 20 years, the application area has continued to expand. my country began to study the influence of trace elements on plant growth and development since the 1940s. In the 1950s, he started to study the content and form of soil trace elements. In the 1960s, the research on the application of micro-fertilizers in production began, and it was found that the application of molybdenum fertilizers in soybeans significantly increased the yield; the soil was de...

Problems solved by technology

[0009] In agricultural applications, due to the high cost of superabsorbent resins, the application and promotion of superabsorbent resins have been seriously hindered. Many domestic scientists have done a lot of work in reducing the cost of superabsorbent resins, but most of the work is mainly concentrated on Add cheap materials such as bentonite, kaolin and attapulgite to the polymerization system to achieve the purpose of reducing costs. Although adding some inorganic minerals can improve the hydrogel strength of the water-retaining material after absorbing water, but the performance is high. The amount of resin soil added is low, which cannot fundamentally reduce the cost of raw materials

In addition, the product function only has the same water absorption and water release functions as ordinary water-absorbent resins, and lacks nutritional functions.

[0010] The invention patent application with the publication number CN101113119A discloses a water-retaining fertilizer and its preparation method. It is prepared by mixing a superabsorbent resin with a chelating agent. The chelating agent is used to provide some nutrients, and this method has no way to reduce The processing cost of superabsorbent resin and the addition of various components to the finished product further increase the manufacturing cost, and the proportion of trace elements in the fertilizer is unbalanced, making it difficult to achieve a good fertilizer effect
