Problems solved by technology

In addition, the soil in the north is alkaline, and the pH value is mostly above 8.0. Phosphorus and some trace elements in the soil are easy to be fixed. Therefore, it is difficult to topdress crops under the condition of full film mulching, the fertilizer utilization rate is not high, and the effectiveness of nutrients in the soil is improved. It is necessary for the further popularization and application of the above technologies
However, the fertilizers usually applied are mainly slow-release fertilizers and special fertilizers for corn. Their functions are only to provide nutrients for crops and increase yields, without changing the micro-ecological environment in the root zone of crops and activating nutrients in the soil. The products of corn irrigation fertilizer on alkaline soil are also rarely reported. Therefore, the development of a full-film mulching irrigation fertilizer that integrates fertilization, improvement of soil micro-ecological environment, and activation of nutrients in the soil is of great significance for improving corn yield and soil productivity. At the same time, it will play a positive role in accelerating the sustainable development of new dry farming technologies, promoting agricultural efficiency, and increasing farmers' income.

Abstract

The invention discloses a full-film-covered corn irrigation fertilizer, which consists of the following components in terms of weight percentage: 25.5%-33.0% of pure nitrogen, 11.0%-15.4% of phosphorus pentoxide, and 6.0%-12.0% of potassium oxide , the trace element zinc 0.34%-0.45%, the trace element manganese 0.16%-0.33%, the raw materials according to the above ratio are crushed and sieved, and then crushed and sieved again after mixing according to the ratio. The beneficial effect of the present invention is: a kind of whole-film-covered maize acid injection irrigation fertilizer provided by the present invention is aimed at the excessive growth of crops in the early stage of one-time fertilization existing in the popularization and application of technologies such as double-furrow rain collection and drought-resistant cultivation and one-film multi-year use. Defertilization in the middle and later stages, low water and fertilizer utilization rate, difficulty in topdressing with one film for many years, and fixation of phosphorus and some trace elements on alkaline soil, etc., according to the law of fertilizer demand of corn and the characteristics of northern soil, macronutrients and trace elements It is formulated according to a certain ratio, and its main function is to improve the soil micro-ecological environment in the root zone of crops, activate nutrient elements that are easily fixed under alkaline conditions, and increase crop yield.

Description

technical field [0001] The invention relates to an injection irrigation fertilizer and a preparation method thereof, in particular to a full film covering corn injection irrigation fertilizer and a preparation method thereof. Background technique [0002] With the popularization of high-efficiency utilization technologies such as full-film double-ridge rain-collecting ditch sowing and one-film multi-year use in rain-fed agricultural areas, crop yield and water efficiency have been significantly improved, but there are problems in the application of excessive crop growth after one-time fertilization , Dehydration and defertilization in the middle and late stages, difficulty in topdressing fertilizer after mulching, and low fertilizer utilization rate have seriously affected the full play of the technical effect. Therefore, the research and development of irrigation fertilizer that integrates nutrient supply and regulation can not only improve fertilizer utilization rate, but ...
