Internode-shortening anti-adverse liquid fertilizer with function of strengthening seedlings and preparation method thereof

Abstract

The invention discloses an internot-shortening anti-adverse liquid fertilizer with a function of strengthening seedlings. The liquid fertilizer is prepared from the following raw materials (by weight): 25-35 parts of calcium nitrate, 4-5 parts of Polygonum aviculare, 280-320 parts of powdery potassium metasilicate, 4-8 parts of tobacco residue, 4-6 parts of bone meal, 8-12 parts of a mepiquat chloride preparation, 5-9 parts of castor hull, 9-12 parts of rice chaff, 3-5 parts of propolis, 2-4 parts of citric acid, 15-25 parts of a chlormequat chloride preparation, 23-27 parts of potassium selenite, 8-14 parts of borax, 6-8 parts of gesso powder and 800-900 parts of an auxiliary agent. By synergism of chlormequat chloride and mepiquat chloride, height-control and internot-shortening effects are achieved, growth and development of crop roots are promoted, stress resistance of crops is enhanced, and bad environment influence can be effectively resisted. By adding extracting solutions of various different substances such as tobacco residue, propolis, castor hull, etc., nutrition ingredients of the liquid fertilizer are enriched, crop quality is improved, and application range of the liquid fertilizer is broadened.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a shrinkage and anti-inferior liquid fertilizer with the function of strengthening seedlings 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. There wer...

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
