Formula fertilizer for glutinous corn in Shajiang black soil area and application technique

Abstract

The invention discloses a formula fertilizer for glutinous corn in a Shajiang black soil area and an application technique, and relates to the technical field of crop cultivation. The formula fertilizer is prepared from the following raw materials according to a proportional ratio by weight: 14 to 16 parts of nitrogen fertilizer N, 7 to 8 parts of phosphor fertilizer P2O5, 5 to 6 parts of potassium fertilizer K2O, 50 parts of granulating chicken manure, 50 parts of granulating swine manure, 0.25 parts of molybdenum sulfate fertilizer, and 0.5 part of zinc sulfate fertilizer. The formula fertilizer is characterized in that 3kg of nitrogen fertilizer is applied as the base fertilizer per mou, 30% of remaining nitrogen fertilizer is applied in the elongation stage, and 70% of remaining nitrogen fertilizer is applied in the large-horn stage; the phosphor fertilizer, potassium fertilizer, granulating chicken manure, and granulating swine manure are used as base fertilizers, and 0.25 parts of molybdenum sulfate fertilizer and 0.5 part of zinc sulfate fertilizer are sprayed to the leaves. The formula fertilizer for the glutinous corn has the advantages that the effect is good, and the fertility duration is long; the formula fertilizer is suitable for promoting the high-quality glutinous corn with medium and low output in the Shajiang black soil area to reach the effects of stable output, output increase and effect increase.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a formula fertilizer for waxy corn in the Shajiang black soil region and its application technology. Background technique [0002] Shajiang black soil mainly develops in rivers and low-lying flat areas in front of mountains. It has experienced gleization and degleization in the geological history. The soil profile has a mortar layer with carbonate accumulation in the ① lower part, and a colored layer in the middle part. Deep humic acid organic colloid-stained black soil layer, ③ the upper layer has a soil structure of a very shallow dark brown soil layer covered by modern sediments. Therefore, although Shajiang black soil is black in color, its organic matter content is very low, and its soil fertility is extremely poor. Coupled with the parent material of lake and river sediments, the texture is heavy, the content of expansive clay minerals is high, the soil cracks and...

Problems solved by technology

Because of its low-lying terrain and easy waterlogging, poor soil physical and chemical properties and ecological environment, poor soil plowability, short cultivation period, and uneven distribution of precipitation in time and space, drought, waterlogging, barren, stiff, cool, etc. occur frequently and seriously, resulting in The yield of high-quality waxy corn in this area has been low and unstable for a long time
