Nitrogen fertilizer synergist for vegetable planting and application method of synergist

Abstract

The invention relates to a nitrogen fertilizer synergist for vegetable planting and an application method of the synergist. The nitrogen fertilizer synergist is prepared by screening a high-efficiency urease inhibitor (quinhydrone), a nitrification inhibitor (dicyandiamide) and sepiolite with appropriate prices and good effects in a ratio of 1:10:100, 15 to 20kg of synergist is applied per mu in a single season, the synergist serving as a base fertilizer is applied to soil after being fully mixed with other conventionally applied base fertilizers uniformly, and the total amount of a nitrogen fertilizer in the base fertilizer is reduced by 20 to 30 percent compared with the local conventional using amount. The synergist is easy to operate, the yield and quality of vegetables can be improved on the basis that the cost of the nitrogen fertilizer is saved by 20 to 30 percent, the pollution of the nitrogen fertilizer can be relieved to a certain extent, the nitrogen fertilizer is efficiently managed and utilized, and win-win economic benefits and ecological benefits are achieved; and the synergist has a good application prospect in vegetable production, particularly in a vegetable production base with serious soil nitrogen enrichment.

Description

technical field [0001] The invention relates to a nitrogen fertilizer synergist and an application method thereof, in particular to a nitrogen fertilizer synergist combined with a urease inhibitor, a nitrification inhibitor and sepiolite and an application method thereof. Increase the yield of vegetables and improve the quality of vegetables. Background technique [0002] Vegetables have the characteristics of fast growth, short growth period, weak root system and high yield. Nitrogen fertilizer has always played a pivotal role in vegetable cultivation. However, due to the pursuit of high economic benefits by producers, the multi-cropping index is generally high in vegetable production in my country, excessive application of nitrogen fertilizers in continuous planting for many years, unreasonable fertilization and other reasons, resulting in a large amount of waste of nitrogen fertilizers and low nitrogen use efficiency in vegetable production in my country. (Many reports ha...
