Damping-off-resistant silicon-enriched slow release fertilizer for soybeans

Abstract

The invention discloses a damping-off-resistant silicon-enriched slow release fertilizer for soybeans. The fertilizer comprises the following components in parts by weight: 25-30 parts of zeolite, 15-20 parts of a mixed fertilizer, 30-40 parts of urea, 15-20 parts of ammonium dihydrogen phosphate, 12-15 parts of coal ash, 5-7 parts of attapulgite powders, 3-5 parts of diatomite, 3-5 parts of a trace element fertilizer, 2-3 parts of emamectin benzoate, 3-5 parts of a damping-off antibacterial agent and 2-4 parts of a slow release additive. Because of the components such as silicon dioxide, calcium oxide and magnesium oxide contained in zeolite and coal ash, crop straws are hard and lodging-resistant; as a result of the components such as the mixed fertilizer and the trace element fertilizer, the utilization rate of a nitrogen fertilizer and a phosphate fertilizer can be improved; the absorption function is enhanced; the fertilizer and water retaining capacities of soil are improved; by virtue of a synergistic effect of emamectin benzoate and damping-off antibacterial agent, the fertilizer generates a resistance effect on the damping-off of soybeans; as a result of the slow release additive, use of the components affecting the environment is minimized; and the diatomite is non-toxic and pollution-free, so that effects of enriching water, totalling fertilization and slowly releasing the fertilizer are achieved.

Description

Technical field [0001] The invention belongs to the field of fertilizer agriculture, and in particular relates to a soybean silicon-rich slow-release fertilizer resistant to wilt. Background technique [0002] Blight disease mainly damages the base of seedling stems or underground roots, initially oval or irregular dark brown spots. The diseased seedlings wilt during the day and recover at night. The diseased part gradually sinks and shrinks, and some become dark brown when it becomes sick. When the spot expands around the stem. Finally withered and died, but did not fall down. Mildly diseased plants only saw brown sunken spots and did not die. When the seedbed has high humidity, inconspicuous light brown spider filamentous mold can be seen in the diseased part. Blight does not produce flocculent white mold, does not fall down, and the disease progresses slowly. Can be distinguished from cataplexy. [0003] Abamectin is a macrolide disaccharide compound. It is a natural produc...

Problems solved by technology

[0005] At present, the traditional compound fertilizers on the market contain less nutrients, which cannot fully meet the needs of crop growth, and the price is high, and the effect of increasing production is not obvious. In addition, there are problems such as low fertilizer utilization rate and excessive application amount.

At present, some compound fertilizers are also used in agricultural production, but their usage is less

The currently used silicon-potassium fertilizer has short fertilizer efficiency, low utilization rate of active ingredients, single function, and cannot improve the utilization rate of binary compound fertilizer.
