Formulated fertilizer for wheat planting

Abstract

The invention discloses a formulated fertilizer for wheat planting. The formulated fertilizer for wheat planting is prepared from the following raw materials in parts by weight: 10-20 parts of humic acid, 10-16 parts of a mixture of potassium sulfate and potassium chloride, 50-65 parts of a mixture of diammonium phosphate, calcium superphosphate, ammonium hydrogen carbonate and ammonium sulfate, 10-15 parts of ammonium dihydrogen phosphate, 0.3-0.8 part of boric acid, 1-2 parts of manganese sulfate, 1-2 parts of ammonium molybdate, 6-10 parts of thoroughly decomposed sesame seed residue, 2-3 parts of a bactericidal drug, 0.3-0.5 part of zinc chloride, 0.3-0.5 part of magnesium carbonate, 1.8-3 parts of rare earth and 2-3 parts of a selenium fertilizer. The formulated fertilizer for wheat planting has the advantages as follows: the formulated fertilizer for wheat planting is high in utilization rate, has certain disease-resisting, pest-resisting and bactericidal effects, promotes normal growth and development of wheat, provides good nutritional elements for the wheat, improves the yield and the quality of the wheat, reasonably supplies nitrogen, phosphorus and potassium nutrients in a balanced manner, supplements trace elements to soil, does not cause soil hardening, reduces the environment pollution, ensures the high and stable yield of the wheat, and enhances the nutritional value of the wheat.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a formula fertilizer for wheat planting. Background technique [0002] Wheat is the general name of wheat plants. It is a monocotyledonous plant and a gramineous plant widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. After being ground into flour, it can be used to make bread, steamed buns, biscuits, and noodles. and other foods; after fermentation, it can be made into beer, alcohol, liquor (such as vodka), or biofuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C, etc. [0003] The fertilization of wheat is mainly based on urea, ammonium bicarbonate, diammonium phosphate and a few concentrated general-purpose compound fertilizers. The application of these fertilizers has brought serious problems such as excessive fertilization and unbalanced nutrient...

AI Technical Summary

Problems solved by technology

The application of these fertilizers has brought serious problems such as excessive fertilization and unbalanced nutrient supply to wheat production, because these fertilizers do not take into account the local soil nutrient supply status, and only determine the formula according to the amount of nutrients absorbed by the crops, often resulting in phosphorus, potassium, etc. The amount of nitrogen fertilizer used is too high, and phosphorus is negatively correlated with grain protein content; the distribution of nitrogen fertilizer in different growth stages of crops is not considered, and the amount of nitrogen fertilizer used in the whole growth period is all placed on the base fertilizer. On the one hand, it is necessary to topdress nitrogen fertilizer, resulting in a waste of fertilizer
