Problems solved by technology

The three elements of nitrogen, phosphorus, and potassium have different decomposition and transformation rules under soil environmental conditions. For example, the mobility of nitrogen is greater than that of phosphorus and potassium, but the aftereffect is not as long as that of phosphorus and potassium, and the validity period of the three-element fertilizer is also short. For example, nitrogen is 50-60 days, potassium is 60-70 days, and phosphorus has accumulated for several years or even longer. Therefore, it is difficult to keep the release rate of nitrogen consistent with phosphorus and potassium, and it is difficult to meet the requirements of crop growth period. Although the proportion of nitrogen, phosphorus, and potassium is consistent with the characteristics of crop fertilizer absorption when artificially designing and producing special compound fertilizers, the fertilizer efficiency changes greatly due to various factors after being applied to the soil, resulting in a decrease in fertilizer efficiency.

Abstract

The invention relates to a slow-control ecological compound fertilizer. At present, the utilization rate of fertilizers in China is low, and the loss is particularly serious. The slow-control ecological compound fertilizer comprises the following constituents according to the parts by weight: 12-21 of nitrogen, 6-11 of phosphorus pentoxide, 8-17 of potassium oxide and 1 of synergistic agent, wherein one part of the constituents comprises the following components by the weight percent: 1-5 of humic acid, 14-19 of zeolite, 1 of additive agent, 0.1-0.2 of thiourea, 0.2-1 of trace element Zn, 0-0.5 of manganese, 0-0.2 of copper, 0-0.5 of boron, 0-0.4 of iron and the balance of a mixture of the nitrogen, the phosphorus pentoxide and the potassium oxide according to the proportion. The slow-control ecological compound fertilizer is for agricultural use.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a slow-control ecological compound fertilizer. Background technique [0002] The development, popularization and application of chemical fertilizers once dominated the first agricultural technological revolution, making ancient agriculture move towards modern agriculture, resulting in leaps and bounds, and promoting economic development and social progress. However, large amounts of chemical fertilizers were used, especially improper application It has also brought many problems, such as chemical fertilizers pollute the environment, low utilization rate of chemical fertilizers, short fertilizer validity period, soil compaction of chemical fertilizers and poor quality of crops due to excessive application of chemical fertilizers. [0003] After general fertilizers are applied to the soil, nitrogen is decomposed and transformed by soil urease and nitrifying bacteria; ammonium nitrogen ...
