Preparation of special high-tower water-retention long-acting fertilizer for improving wheat quality and application of fertilizer in wheat topdressing

Abstract

The invention provides a wheat reviving elongation stage topdressing fertilizer and application thereof in wheat cultivation. The fertilizer comprises a nitrogen source, a water-retaining agent, aminoacid, a nitrification inhibitor, a phosphorus source, a potassium source, a sulfur source, a zinc source, a boron source and a manganese source. The fertilizer disclosed by the invention is rich in various nutrient substances, and particularly the water-retaining agent, the amino acid and the nitrification inhibitor are added, so the mutual inhibition among all elements is reduced, and the growthrequirements of wheat, especially the requirements of different nutrients in the reviving and elongation stage, are met. The fertilizer is applied to wheat land parcels in the reviving elongation stage in cooperation with spring irrigation, nutrient supply conforms to the fertilizer requirement law of wheat, and the fertilizer has the advantages of being quick-acting, slow-release, long-acting, efficient and the like, can effectively improve the nitrogen production efficiency, improve soil, improve the wheat quality and increase the wheat yield and is suitable for large-scale application.

Description

technical field [0001] The invention relates to the field of chemical fertilizers. Specifically, the invention relates to the preparation of a special high-tower water-retaining long-acting fertilizer for improving wheat quality and its application in wheat topdressing. Background technique [0002] In recent years, the planting area of ​​high-quality wheat in my country has continued to increase, but the domestic production and sales of high-quality wheat used in the production of bread, noodles and other food products are still in short supply. In 2019, my country's import volume was about 3.5 million tons, which was equivalent to the output of 7.7 million mu of good-field wheat. The high-quality wheat that enterprises really needed was still being imported in a steady stream. The high-quality wheat grown by domestic farmers could not achieve its due value. [0003] Improving wheat protein content and stabilizing time are the key points to improve wheat quality and realize...

Problems solved by technology

[0002] In recent years, the planting area of ​​high-quality wheat in my country has continued to increase, but the domestic production and sales of high-quality wheat used in the production of bread, noodles and other food products are still in short supply.

In 2019, my country's import volume was about 3.5 million tons, which was equivalent to the output of 7.7 million mu of good-field wheat. The high-quality wheat that enterprises really needed was still being imported in a steady stream. The high-quality wheat grown by domestic farmers could not achieve its due value

However, this method of topdressing is likely to cause difficulty in machine operation and damage to the wheat. It is difficult to realize the combination of agricultural machinery and agronomy, and it will increase the cost of topdressing.

[0005] Therefore, the fertilizers suitable for topdressing at the jointing stage of wheat rejuvenation still need to be studied
