Corn planting method to prevent and control typhoon stress

Abstract

The invention discloses a corn planting method to prevent and control typhoon stress, comprising: preparing a land, to be specific, forming ridges, and selecting a plot that has upper-medium fertilityand that is properly plowed to remove stubbles and raked finely, wherein ridging breadth is 75-85 cm, ridge top width is 55-65 cm, ridge-ditch width is 36-44 cm, and ridge height is 12-16 cm; selecting seeds and sowing the seeds, to be specific, selecting a mainly-popularized variety suitable for local production, and performing seeding; applying fertilizer; performing field management accordingto field level. The corn planting method employs a ridge cultivation mode; chances for corn to lodge in case of a typhoon can be effectively decreased, waterlogging damage is relieved, and kernel number per spike and thousand kernel weight are significantly higher than those of convention planting; a ridge dual-row planting mode is employed, wide-row planting and narrow-row planting are combined,and waterlogging damage is effectively reduced, lodging rate of corn is reduced, ventilating and light transmittance are benefited, and corn yield is greatly increased; the corn planting method has good yield increase and good anti-waterlogging effect, has a promising popularization and application prospect and has great practical significance.

Description

technical field [0001] The invention relates to the technical field of crop planting and cultivation, and more specifically, to a corn planting method for preventing and controlling typhoon climate stress. Background technique [0002] my country is one of the countries most affected by typhoons, and the frequent landfall of typhoons poses a major threat to agricultural production. According to statistics, there are more than 20 typhoons that have a major impact on my country every year, and the strong winds and rainstorms brought about by the typhoon climate have caused serious reductions in agricultural production. [0003] As we all know, the Huang-Huai-Hai area is an important grain-producing area in my country, and typhoons are more likely to occur in this area, and crops are more vulnerable, so higher requirements are put forward for cultivation management measures. In the Huanghuaihai region of my country, most typhoons occur during the summer corn growing season, ca...

Problems solved by technology

[0004] At present, my country has done a lot of work on the forecast and early warning of typhoon climate, but there are few reports on the research on the resistance of crops to typhoon stress. The research on the mechanism of crop resistance to lodging and waterlogging has a mature theoretical system, but most of them tend to choose their varieties Research on the regulation of biochemical agents and biochemical agents, there are few cultivation management measures to unify the two, the selection of varieties takes too long, and lodging resistance is not necessarily waterlogging resistant, and biochemical agents have a great negative impact on the ecological environment
