Problems solved by technology

Farmers cannot effectively grasp the characteristics of varieties. Most of the people engaged in corn production are the elderly and women. They have weak ability to accept new technologies, and the management is relatively extensive. Diseases and insect pests are showing a tendency to intensify, resulting in a decline in the yield and quality of summer corn.

Embodiment Construction

[0008] 1. Selected varieties. The selected varieties require compact plant type, resistance to dense planting, lodging resistance, density of more than 5,000 plants / mu, no lodging, no empty stems, no bald tips, an average grain weight potential of more than 200 grams, and about 105 days of summer sowing. Seeds of the same size should be soaked for 8 hours, and after drying, use 40% ethion-methyl and 2% Likexiu as the seed dressing according to 0.2% of the seed mass to prevent rough dwarf disease, seedling blight, smut and underground pests . 2. Sow finely. Fine plowing and land preparation before sowing, 3 cubic meters of high-quality chicken manure per mu, 10 kg of phosphorus pentoxide, 30 kg of potassium oxide, 1 kg of zinc fertilizer, and 1.5 kg of 5% phoxim granules. Sow from June 5th to 15th, plant in large and small rows, with a large row spacing of 80 to 90 cm and a small row spacing of 30 to 40 cm. Apply 5 kg of compound fertilizer per mu as seed fertilizer. centi...

Abstract

The invention relates to a novel super-high-yield cultivation technology of summer maize. The technology has the characteristics that by the processes of carefully selecting improved varieties, sowing the seeds precisely, improving the density, applying fertilizer sufficiently, conducting precision management, controlling weed and pests, etc., the effects of avoiding diseases and pests, increasing yield and increasing efficiency of the summer maize can be achieved. And the novel technology is suitable for high yielding cultivation of the summer maize.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a new technology for super-high-yield summer maize cultivation. Background technique [0002] At present, there are many varieties of summer maize promoted. Farmers cannot effectively grasp the characteristics of varieties. Most of the people engaged in corn production are the elderly and women. They have weak ability to accept new technologies, and the management is relatively extensive. Diseases and insect pests are showing a tendency to intensify, resulting in a decline in the yield and quality of summer corn. Contents of the invention [0003] In order to solve the technical problem of low-yield summer maize, the invention invents a new technology for super-high-yield summer maize cultivation. [0004] In order to solve the above-mentioned technical problems, the present invention adopts a technical solution, a new technology for cultivating super-high-yield summer maize, whic...
