Drought-resistant high-nitrogen-content plant fertilizer

Abstract

The invention discloses a drought-resistant high-nitrogen-content plant fertilizer. The drought-resistant high-nitrogen-content plant fertilizer is characterized by comprising the following fertilizer components in parts by weight: 10-20 parts of urea, 10-20 parts of a urea-formaldehyde resin water solution, 10-20 parts of humic acid, 5-10 parts of potassium sulfate, 5-10 parts of itaconic acid, 10-15 parts of ammonium dihydrogen phosphate, 3-5 parts of a sodium alginate solution, 3-5 parts of EDTA, 4-6 parts of fish meal, 4-6 parts of chitin, 3-6 parts of 5% polyaspartic acid, 4-6 parts of an EM original solution, 10-15 parts of original solution carriers and 4-6 parts of saccharose. The drought-resistant high-nitrogen-content plant fertilizer has very strong water-absorbing quality and is capable of effectively improving physical properties of soil; the components of the drought-resistant high-nitrogen-content plant fertilizer have the functions of increasing plant nutrients, promoting plant growth and resisting plant diseases.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a drought-resistant and high-nitrogen plant fertilizer. Background technique [0002] Nitrogen fertilizers are chemical fertilizers containing the crop nutrient nitrogen. Elemental nitrogen plays a very important role in crop growth. It is a component of amino acids in plants, a component of protein, and a component of chlorophyll that plays a decisive role in photosynthesis in plants. Nitrogen also helps crops disperse. The application of nitrogen fertilizer can not only increase the yield of agricultural products, but also improve the quality of agricultural products. [0003] One of the problems encountered in the widespread use of nitrogen fertilizers is that a certain portion of the nitrogen is lost after application in various ways, including volatilization as ammonia, denitrification to gaseous nitrogen, and nitrate leaching. Despite their inherent ineff...

[0004] At present, chemical fertilizers have become the leading fertilizers for basal fertilizers and topdressing fertilizers in my country. However, long-term use of chemical fertilizers alone will cause soil compaction, decreased aeration, poor water retention and drainage, and fertilizer efficiency disappears too quickly, and insufficient prolongation. The practice of long-term single use of chemical fertilizers has proved that , Chemical fertilizers can also cause changes in soil biological populations that are unfavorable to crop growth. Sometimes, some crops are easily affected by diseases and die during continuous cropping. This is due to the large amount of organic fertilizer used per unit area and the supply of Insufficient, the deterioration of soil quality caused by chemical fertilizers is difficult to overcome in our country in the short term

[0005] Moreover, the use of the above-mentioned various chemical fertilizers mostly requires a large amount of water to dilute the irrigation. As we all know, if the land with good water conservancy conditions is frequently irrigated, the soil will also harden, which will affect the normal growth of crops. The fertilizers currently used, whether they are farmyard manure or chemical fertilizers, cannot fully exert their due effects if they are not diluted with a large amount of water.
