High-yield corn planting method

Abstract

The invention discloses a high-yield corn planting method belonging to the technical field of agriculture, forestry, animal husbandry, hunting, trapping and fishing, and particularly relates to a corn planting method. The invention provides the high-yield corn planting method which is high in yield and is green and pollution-free. The high-yield corn planting method comprises the following steps of (1) isolated planting: sowing by stages is carried out since sweet corn and waxy corn can be in out-crossing hybridization with common corn and grains of the sweet corn and the waxy corn can easily change into grains of the common corn; (2) seed preparation: elite hybrid seeds can be selected as the elite hybrid seeds have good yield-increasing potential and are the high-yield basis of corn; appropriate elite seeds can be selected by combining ecological types of different regions; (3) seed processing: appropriate seeds coated by a seed coating agent can be selected before seeding according to a local disease and pest occurrence regularity, or seed dressing processing can be carried out on seeds by selecting related pest killing agents, disinfecting agents, micro-element fertilizer and the like according to needs, so that the purposes of preventing diseases and pests and promoting the growth can be achieved; (4) land ploughing and land preparation: the appropriate tilling depth is 18 cm; the tilling depth can be up to 20 cm for the land which is high in soil fertility, thick in tilling layer and large in basic fertilizer application amount; otherwise, the tilling depth needs to be shallow; (5) seeding depth: generally, the appropriate seeding depth is 4 to 6 cm; but generally, the seeding depth is required not to exceed 8 cm. Attention, a great number of ineffective tillers can be generated during a seedling stage if the soil which is better in soil moisture content and better in fertility is subjected to too-shallow seeding.

Description

technical field [0001] The invention belongs to the technical fields of agriculture, forestry, animal husbandry, hunting, trapping and fishing, and particularly relates to a corn planting method. Background technique [0002] Corn is China's largest food crop. In the biological range, corn is a C4 plant, but the bracts use C3 mode for photosynthesis, which is a monoecious plant. The main production area is located in the third largest corn belt in the world - China's Songliao Plain corn belt. The total planting area of ​​corn is about 1249.35 square kilometers, also known as maize, corn (corn stick), corn, stick, and mallet. The Mufu mountain system in Hubei is called Yulu (because the rhizome looks like a reed, and the fruit has the water head of jade), Chaoshan dialect is called Youmeiren (because it was introduced from the Americas), Cantonese is called corn, and Hokkien is called Fanmai. It is called "Baoxiu". It is an annual grass herb, an important food crop and an ...
