Problems solved by technology

[0004] Although the foliar fertilizer market is developing rapidly, the quality of commercially available products is uneven. Simply put, there are mainly the following problems: (1) The specificity of the products is not strong. Many products claim to have a wide range of applications, but the effects of different crops are uneven Incomplete, lack of products with good effect and strong specificity for specific crops; (2) Incomplete nutrition, foliar fertilization provides a limited number of nutrients, which is not enough to meet all the needs of crops; (3) Poor fertilizer efficiency, especially boron , manganese, molybdenum, zinc and other trace elements absorption efficiency is not ideal; (4) leaf adhesion is poor, most foliar fertilizers are easy to drip from the leaf surface, and the retention time on the leaf surface is short, resulting in some nutrient loss; (5) fertilizer efficiency is short , most of the foliar fertilizers are effective quickly but the fertilizer effect lasts for a short time

Abstract

The invention discloses a special foliar fertilizer for wheat, in particular to a special foliar fertilizer product for wheat in an elongation stage and a booting stage. The foliar fertilizer contains various major elements and trace elements required by wheat and can be compounded with photosynthetic bacteria, an efficient plant growth regulator, an adsorbent and a spreading agent to improve biological activity of the foliar fertilizer and improve drought resistance, lodging resistance and disease resistance of wheat, and accordingly wheat yield can be increased remarkably.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a wheat-specific foliar fertilizer, and more particularly to a wheat-specific foliar fertilizer suitable for spraying at the jointing stage and the booting stage. Background technique [0002] Chemical fertilizers are important means of agricultural production and the "grain" of food crops. Over the years, chemical fertilizers have played an irreplaceable role in promoting my country's grain production and agricultural development. However, there are still problems such as excessive and blind application of chemical fertilizers, especially the traditional soil fertilization methods, which are extremely serious to soil damage. At the same time, they are harmful to the environment. It also causes great pollution. At present, the hazards of long-term application of chemical fertilizers in the soil have already appeared, such as causing soil compaction, soil water an...
