Nitrosulfur-based compound fertilizer suitable for planting fruit trees and preparation method thereof

Abstract

The invention discloses a nitro-sulfur based compound fertilizer applicable to fruit tree planting. The nitro-sulfur based compound fertilizer is prepared from main materials and auxiliary materials, wherein the main materials comprise the following materials in parts by weight: 30 to 40 parts of ammonium nitrate phosphorus, 20 to 35 parts of potassium sulphate, 15 to 25 parts of potassium nitrate, and 10 to 25 parts of monoammonium phosphate; the auxiliary materials comprise the following materials in parts by weight: 3 to 7 parts of magnesium oxide, 2 to 4 parts of instant-dissolved boron, 3 to 7 parts of ferric oxide, 2 to 5 parts of zinc sulfate, 5 to 12 parts of sodium humate, 0.05 to 0.1 part of compound sodium nitrophenolate, 0.3 to 0.7 part of JT composite strain powder, 0.1 to 0.5 part of urea-based chelated ionized calcium, and 0.5 to 2.0 pats of anti-blocking agent. The nitro-sulfur based compound fertilizer applicable to fruit tree planting can be stored for a long term without blocking, so that the soil can be effectively prevented from blocking; in addition, the nitro-sulfur based compound fertilizer applicable to fruit tree planting has the effects of preventing and resisting diseases and increasing output and yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nitrosulfur-based compound fertilizer suitable for planting fruit trees. Background technique [0002] During the growth process of fruit trees, it is necessary to absorb appropriate amounts of various mineral nutrients from the soil to maintain their normal growth and development, including macronutrients such as nitrogen, phosphorus, and potassium, secondary elements such as calcium, magnesium, and sulfur, and micronutrients such as Iron, manganese, copper, zinc, boron, etc., especially in the germination, flowering and fruit setting stages of fruit trees in early spring, the application of quick-acting fertilizers with complete nitrogen, phosphorus and potassium has a significant impact on the development of fruit trees and the quality and yield of fruit. [0003] Nitrosulfur-based compound fertilizers generally contain more nitrate nitrogen and a certain amount of ammon...

Problems solved by technology

Although the nitrosulfur-based compound fertilizer has the advantage of fast fertilizer efficiency, at the same time, the nitrosulfur-based compound fertilizer is easy to absorb moisture and agglomerate under long-term storage conditions. The permeability is reduced. In the case of poor soil aeration, nitrate can be denitrified to form N 2 O and N 2 , thus causing the loss of nitrogen; the third is that the nitrosulfur-based compound fertilizer is easy to form agglomerates and affect its commodity value after long-term storage. Generally, talcum powder is used to wrap the compound fertilizer, although the agglomeration of the product is reduced to a certain extent problem, but increases the dust content in the product
