Special water-retaining and synergistic seaweed fertilizer rich in medium trace elements for chilli, and preparation method thereof

Abstract

The invention discloses a special water-retaining and synergistic seaweed fertilizer rich in medium trace elements for chilli. The special water-retaining and synergistic seaweed fertilizer comprises the following raw materials in parts by weight: 100-360 parts of seaweed extract, 100-360 parts of ammonium nitrate phosphate, 100-380 parts of urea, 100-450 parts of monopotassium phosphate, 0-100 parts of calcium-magnesium phosphate fertilizer, 0-60 parts of EDTA chelated trace elements, 0-30 parts of biological synergist and 5-300 parts of filler. The special water-retaining and synergistic seaweed fertilizer disclosed by the invention is capable of promoting the root development of chilli, enhancing the disease-resistant capacity of the roots, stems and leaves of crops, increasing the content of chlorophyll, increasing the efficiency of photosynthesis, improving the photosynthesis of the crops, and increasing the activity of enzymes because an appropriate amount of trace elements necessary to the growth of chilli, and alginic acid are added; and meanwhile, absorption and utilization for the nutrients and water of soil are improved, the yield is greatly increased, and the quality is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special seaweed fertilizer rich in medium and trace elements for water retention and efficiency enhancement for capsicum and a preparation method thereof. Background technique [0002] Compared with simple fertilizers, nitrogen, phosphorus and potassium ternary compound fertilizers can better meet the nutrient requirements during the growth cycle of crops, avoid excessive elements in the soil and lack of nutrients, and achieve balanced fertilization with higher yields. The role of medium and trace elements has attracted more and more people's attention, and they are playing an increasingly important role in modern agricultural production. [0003] Seaweed fertilizer is a natural seaweed extract, which has incomparable advantages in natural activity, stress resistance, non-toxic, non-polluting, etc., and is convenient to transport, simple to apply, high in the ab...

Problems solved by technology

[0006] At present, when peppers are fertilized, chemical fertilizers, urea, organic fertilizers and other raw materials are generally used to topdress peppers. Although the effect is good, the nutrients contained in chemical fertilizers and urea are far from meeting the nutritional needs of peppers. The leaves are yellow, the leaves are small, the growth is slow, the peppers produced are small, light in weight, poor in disease resistance, prone to leaf spot disease, and more prone to various diseases and insect pests
