specific Embodiment approach 1

[0005] Specific embodiment 1: Refer to Table 1 for the distribution ratio of various components in this embodiment. The superabsorbent prepared by acrylamide and sodium acrylate is prepared according to the following steps: a, prepare 500ml of acrylamide aqueous solution with a weight concentration of 50%, and 500ml of a weight concentration of 40% sodium acrylate solution; b , two kinds of monomer solution are packed in the plastic container, then add the NN'-methylenebisacrylamide 4ml, 2.5g disodium ethylenediamine tetraacetate, 2g K 2 S 2 o 8 and 2gNa 2 SO 3 ; C, then the container of holding solution is imported into 60 Coγ-irradiation indoor irradiation, wherein the irradiation dose is 2.5KGY; d, after the radiation copolymerization and cross-linking reactions are completed, slice, dry, and pulverize. This embodiment is suitable for coating the seeds of crops such as corn, wheat, and rice.

specific Embodiment approach 2

[0006] Specific embodiment 2: Refer to Table 1 for the distribution ratio of various components in this embodiment. The superabsorbent prepared by acrylamide and sodium acrylate is prepared according to the following steps: a, preparing 500ml of acrylamide aqueous solution with a weight concentration of 60%, and 500ml of a 30% sodium acrylate solution; b 1. Put the two monomer solutions into a plastic container, then add 5ml of NN'-methylenebisacrylamide, 3g of ethylenediaminetetraacetic acid disodium, 2g of K 2 S 2 o 8 and 2gNa 2 SO 3 ; C, then the container of holding solution is imported into 60 Coγ-irradiation indoor irradiation, wherein the irradiation dose is 3KGY; d, after the radiation copolymerization and cross-linking reactions are completed, slice, dry, and pulverize. The proportioning of this embodiment is suitable for coating the seeds of crops such as cotton and sugar beet.

specific Embodiment approach 3

[0007] Specific embodiment three: Refer to Table 1 for the distribution ratio of various components in this embodiment. The superabsorbent prepared by acrylamide and sodium acrylate is prepared according to the following steps: a, prepare 500ml of acrylamide aqueous solution with a weight concentration of 45%, and 500ml of a weight concentration of 40% sodium acrylate solution; b 1. Put the two monomer solutions into a plastic container, then add NN'-methylenebisacrylamide, 3g disodium edetate, 2g K 2 S 2 o 8 and 2gNa 2 SO 3 ; C, then the container of holding solution is imported into 60 Coγ-irradiation indoor irradiation, wherein the irradiation dose is 4KGY; d, after the radiation copolymerization and cross-linking reactions are completed, slice, dry, and pulverize. This embodiment is suitable for coating the seeds of crops such as soybeans and peanuts.

Abstract

The dry farming seed coating agent relates to a non-engineering anti-drought product, in particular to a seed treatment agent. The present invention is composed of the following components according to the ratio by weight percentage: 71-78 superabsorbents made of acrylamide and sodium acrylate, 15-21.71 nutrients, 0.3-0.6 plant growth regulators, and 1.0-1.0 bactericides 3.0, insecticide 4.0 ~ 10.0. The feature of the invention is a novel seed coating agent mainly composed of a super water-absorbing agent, which has the functions of water absorption, water retention, fertilizer retention, wilting resistance, sand fixation, sterilization and strong rooting. The early cropping seed coating agent of the present invention contains nitrogen, phosphorus, potassium, calcium, magnesium, iron, boron, manganese, zinc, copper, molybdenum and other complete nutrients, and the ratio of each nutritional element is optimized by isotope tracer technology. The optimal ratio, scientific composition; the seed coating contains plant growth regulators, and the optimized combination of these ingredients can stimulate plant rooting and improve drought resistance; the fungicides and insecticides in the seed coating have fungicidal and disease resistance and Insecticidal effect.

Description

Technical field: [0001] The invention relates to a non-engineering drought-resistant product, in particular to a seed treatment agent. Background technique: [0002] Existing seed coating agent, contains pesticide, micro-fertilizer, trace element and other supporting auxiliary agent as the medicine-fertilizer compound type seed coating agent (CN86100095A) of Beijing Agricultural University invention. In 1993, a "drought-resistant seed compound coating agent" (CN1070799A) was disclosed by the State Patent Office. Contains 3 to 4.5%. In 1995, CN11420.1 "Drought Resistant Seed Composite Coating Agent and Preparation Method" was published, which contained pesticides, trace elements, and 1.8-2.8% polymer water-absorbing agent. In 2000, CN1246283A "drought-resistant seed compound seed coating agent" was disclosed. The seed coating agent contains pesticides, trace elements, plant growth regulators, etc., and the polymer water-absorbing agent contains 6.0-8.8%. At present, the di...
