Liquid fertilizer with seedling strengthening and silicon absorption promoting functions and preparation method of liquid fertilizer

Abstract

The invention discloses a liquid fertilizer with seedling strengthening and silicon absorption promoting functions. The liquid fertilizer is prepared from raw materials in parts by weight as follows: 7-9 parts of dregs of sweet wormwood herb,9-15 parts of whey powder, 3-4 parts of wintergreen oil, 8-12 parts of a mepiquat chloride preparation, 6-8 parts of biogas slurry, 11-15 parts of fermented sorghum stems, 20-30 parts of sodium molybdate, 15-18 parts of zinc chloride, 9-14 parts of calcite, 5-7 parts of Japanese hop herb, 280-320 parts of powdery potassium metasilicate, 15-25 parts of a chlormequat chloride preparation, 5-8 parts of lanthanide rare earth, 4-6 parts of animal bone protein and 800-900 parts of an auxiliary agent. The liquid fertilizer solves the problem that effective silicon in traditional silicon fertilizers is not sufficiently converted and released in soil, stable silicate ions are formed through chelation of alkaline potassium silicate and trace elements, crops can absorb silicon better after the liquid fertilizer is used, growth of roots of the crops is facilitated, and the stress resistance is increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a liquid fertilizer with the function of strengthening seedlings and promoting silicon absorption and a preparation method thereof. Background technique [0002] Promoting the cultivation of super rice is a long-term strategy to ensure food security. In 2013, the promotion area of ​​super rice in my country reached 120 million mu, and there have been typical super rice research demonstration pieces exceeding 900 kg per 100 mu across the country. However, common phenomena such as high-yield lodging and machine-harvesting difficulties often occur in the cultivation of super rice, and the lodging-resistant cultivation of super rice has become an important technical problem at present. In the past, the solution was to soak the seeds with paclobutrazol and other plant growth regulators when sowing rice, and to spray them on the leaves at the seedling stage and jointing stage. Ther...

Problems solved by technology

It is a balanced composite system based on liquid potassium silicate and macroelements, trace elements, and organic matter, which can effectively improve the utilization rate of silicon and various nutrient elements by crops, and play a certain role in strong stem lodging resistance of rice, but it is not effective for rice. Strong seedlings have no promoting effect
