Corn seed dressing medicament fertilizer ground substance and its seed dressing medicament fertilizer formulation and preparation method

Abstract

The invention discloses a novel maize seed dressing pesticide and fertilizer substrate and prescription and a preparation method thereof. The substrate comprises the components and contents according to weight: 80-95 portions of acetose attapulgite, 1-6 portions of farm-type neutral polyacrylic acid sodium salt, 2-8 portions of turves, 1-6 portions of multi-effect zinc fertilizer; each 100 portions of substrate is added with 0.05-0.5 portions of farm chemical carbofuran, 0.05-0.5 portions of carbendazim, 0.05-0.5 portions of thiram and / or 0.008-0.05 portions of paclobutrazol. The preparation method is that: the substrate materials are super-finely crushed into fine powder of more than 120 mesh, mixed according to ratio and prepared into the substrate; the farm chemical components are dissolved by the substrate into mother powder with concentration of 1-5 percent, the mother powder is incorporated into the substrate according to ratio, put into a double spiral mixer to be evenly mixed and stirred to get the finished products. The seed dressing pesticide and fertilizer produced through the substrate can be applied to maize seedling, form water retention and slowly releasing pesticide and fertilizer mud balls when the invention is used around the seeds and seedling roots and have a plurality of functions of keeping crop seedling from drought, strong seedling, ensuring strong root and seedling, disease and insects prevention, saving work and cost and increasing output and income, etc.

Description

technical field [0001] The invention relates to a novel seed-dressing fertilizer substrate for corn seedlings, especially a powdery substrate with functions such as water retention, nourishment, slow release, and strong adhesion, and a corn seed-dressing fertilizer using the substrate and a preparation method thereof. Background technique [0002] At present, the known corn seed dressing materials are all single-function seed-dressing medicine or seed-dressing fertilizer, and the carrier of the pesticide and fertilizer is water or fine soil, which obviously has a single function, complicated operation, weak chemical adhesion, and easy There are defects such as phytotoxicity and fertilizer damage. In particular, the main production areas of corn are distributed in arid and seasonally dry areas in my country, and there are common problems in production such as low seedling emergence rate, irregular seedling emergence, and heavy occurrence of seedling diseases and insect pests....
