Problems solved by technology

[0004] What the present invention is to solve is the serious loss of existing fertilizer nutrients, which leads to the problem of low fertilizer utilization rate. It provides a method to reduce fertilizer loss, improve fertilizer utilization rate, increase the need for micro-fertilizers for crops, and increase polypeptide components to increase crop production and absorption. A new type of agricultural compound fertilizer with improved efficiency

Embodiment 1

[0008] Embodiment 1: A kind of novel agricultural compound fertilizer, select the compound fertilizer of high concentration for use, according to the national standard, nitrogen, phosphorus, potassium three content greater than or equal to 40% is the high concentration compound fertilizer, every ton of compound fertilizer Add 5 kg of polyaspartic acid and polyacrylamide to the fertilizer, and stir evenly after adding; adding polyaspartic acid and polyacrylamide to the compound fertilizer can effectively reduce fertilizer loss and activate nutrients. Improve the utilization rate of fertilizers, thereby reducing the amount of fertilizers by more than 30%, and increasing crop yields by 10%-30%; it can better promote the absorption of trace elements such as iron, zinc, manganese, copper, calcium, magnesium, sulfur, etc. The trace content of aspartic acid-treated crops is 3-4 times higher than that of the control crops; it can promote early maturity of crops by 7-10 days and prolong...

Embodiment 2

[0009] Embodiment 2: a kind of novel agricultural compound fertilizer, select the compound fertilizer of high concentration for use, add 5 kilograms of polyaspartic acid, 5 kilograms of polyacrylamide and the ferrous sulfate of 10 kilograms in every ton of compound fertilizer, in use For crops that are highly sensitive to iron content, such as peanuts, soybeans, or broad beans, it enables the crops to better absorb iron in the soil and avoid affecting crop growth due to iron deficiency.

Embodiment 3

[0010] Embodiment 3: A kind of new-type agricultural compound fertilizer, select the compound fertilizer of high concentration for use, add 5 kilograms of polyaspartic acid and 5 kilograms of polyacrylamide in every ton of compound fertilizer, when being used for fertilizing crops such as wheat , because wheat is sensitive to trace elements such as boron, copper and zinc, so it is necessary to add 10 kg of zinc sulfate, borax and copper sulfate mixture to each ton of compound fertilizer, so that the wheat can better absorb the nutrients it needs.

Abstract

The invention discloses a novel agricultural compound fertilizer, and relates to compound fertilizer for agriculture, wherein the novel agricultural compound fertilizer has good synergism and high nutrient utilization rate and reduces the loss rate. The novel agricultural compound fertilizer disclosed by the invention is high-concentration compound fertilizer and is characterized in that polyaspartic acid and polyacrylamide are added into the compound fertilizer, wherein 5kg of polyaspartic acid and 5kg of polyacrylamide are added to each ton of the compound fertilizer; and then the materials are uniformly mixed to obtain the novel agricultural compound fertilizer. For the novel compound fertilizer disclosed by the invention, the compound fertilizer of the national standard is improved according to the plants and soil, the fertilizer loss can be effectively reduced, the trace element absorption of the crop can be promoted, the crop matures 7-10 days earlier, the harvest time is prolonged for 10-15 days, the root growth is promoted, the stress resistance of the crop is enhanced, and the nutrient utilization rate is improved so that the crop can grow better and all needs can be met.

Description

technical field [0001] The invention relates to a compound fertilizer for agriculture, which is a novel agricultural compound fertilizer with good synergy, high nutrient utilization rate and reduced loss rate. Background technique [0002] my country is a country with a large population, and grain production occupies an important position in the development of agricultural production. Usually the way to increase food production is to expand the area of ​​cultivated land or increase the yield per unit area. According to the national conditions of our country, the potential to continue to expand the cultivated land area is not great. Although there are still many uncultivated lands in our country, most of them have the problems of high investment and great difficulty. This determines that my country's grain production must take the way of increasing the yield per unit area. Fertilization can not only improve soil fertility, but also an important measure to increase crop yiel...
