Problems solved by technology

The matrix of this product is wood (grass) vinegar, and film-forming materials and pesticide auxiliaries are added. Although the effects of antibacterial and bactericidal and plant growth regulation have been increased, and the waste of liquid fertilizers after application has been reduced, to a certain extent there are soil Reduced porosity affects its air permeability and high pesticide residues
Retrieval results show that the above-mentioned wood vinegar has good bactericidal and root-knot nematode killing effects, but the common defects of the above two technologies are: 1. The product liquid is relatively acidic, and water and acetic acid are relatively high in concentration. It has a strong buffer capacity under the condition of strong buffering capacity. If the dilution concentration is not enough, it will burn the surface of plant leaves or cause damage to the root system; 2. In the case of relatively strong acidity, it will destroy the stable environment of the soil and affect the growth of crops. To a certain extent, the soil releases heavy metals. These heavy metals are absorbed and enriched by plants, and accumulate in the body after being eaten, causing harm; 3. There are many components, the production process is relatively complicated, and the product cost is high, which is not easy to be accepted by farmers.

Abstract

The invention relates to a pyroligneous-contained liquid compound fertilizer and application. The compound fertilizer is prepared from the following components of 1-2.5 kg of pyroligneous, 1.5-3.0 kg of calcium superphosphate, 0.5-1.0 kg of urea, 0.5-1.0 kg of lactic acid and 48-55 kg of water by the following steps of: preparing the calcium superphosphate to be with the granularity of 20-40 meshes; distilling the pyroligneous at 110-120 DEG C and mixing with the amount of water; soaking the calcium superphosphate for 18-24 h; taking supernatant; adding with the lactic acid and the urea; and evenly mixing. The diluent of the compound fertilizer is used for spraying or root-irrigation of greenhouse vegetables. The compound fertilizers can ensure that the nutrients thereof can be rapidly absorbed by the blades or root systems of the greenhouse vegetables to increase the chlorophyll content of the greenhouse vegetables with obvious fertilizing effect, can increase the average yields of vegetables and fruits by 17.5 percent, can restrain common vegetable diseases, has simple use method and low product price and is easy for peasants to accept. The product has no toxic or side effect, is convenient to prepare, and has small raw material components without heavy metals or fertilizer enrichment and residual after the absorption by plants and belongs to environment-friendly products.

Description

technical field [0001] The invention relates to a liquid compound fertilizer, in particular to a liquid compound fertilizer containing wood vinegar and an application method of the product, which is applied to greenhouse vegetable cultivation, effectively increases the chlorophyll content of greenhouse vegetable leaves, and further improves Effective nutrient preparation for vegetable yield. Background technique [0002] Wood vinegar is an acidic liquid with a pH of 3.0-3.5 and a specific gravity of 1.0025 with acetic acid as the main component. Transparent light yellow liquid) has a unique smoky aroma. Wood vinegar is a natural extract obtained from pyrolysis and carbonization of wood materials by fractional distillation of flue gas. It contains K, Ca, Mg, Zn, Ge, Mn, Fe and other minerals, and contains more than 200 kinds of organic substances, including phenols, Acids, alcohols, ketones, etc., in addition to vitamins B1 and B2, is a complex, functional and relatively st...
