Method for planting corn

Abstract

The invention discloses a method for planting corn, which comprises the following steps of sowing and seedling raising, transplanting, fertilizing, weeding, hilling, moisture management, pest control and timely harvesting. The method improves abilities of soil conservation, fertilizer conservation and water conservation of soil, and corn plants are good in light transmission and ventilation, deep in the root system, and strong in lodging-resistant performance; under the premise of ensuring national food security, applying quantity of chemical fertilizer is reduced, so that cost reduction and income increase are realized for farmers, energy conservation is realized for the country, the environment is protected, and agricultural sustainable development is promoted.

Description

technical field [0001] The invention relates to a corn planting method and belongs to the field of planting technology. Background technique [0002] my country's agricultural system has no standard corn cultivation model so far. Sparse planting and unreasonable close planting are the bottlenecks that restrict the high yield of corn. Especially when corn is tasseling, the three leaves of the cob receive insufficient light, and the corn cob will be bald and lack kernels, resulting in Yield reduction; there is also no standard for farmer ridge formation, blindness and randomness; especially fertilization, most farmers planting corn use traditional methods of blind fertilization, which not only wastes a lot of resources, pollutes the environment, but more importantly, the utilization rate of chemical fertilizers With the continuous expansion of the quantity, it will be greatly reduced, and at the same time, it will lead to the crazy growth of corn leaves and even the outbreak...

[0002] my country's agricultural system has no standard corn cultivation model so far. Sparse planting and unreasonable close planting are the bottlenecks that restrict the high yield of corn. Especially when corn is tasseling, the three leaves of the cob receive insufficient light, and the corn cob will be bald and lack kernels, resulting in Yield reduction; there is also no standard for farmer ridge formation, blindness and randomness; especially fertilization, most farmers planting corn use traditional methods of blind fertilization, which not only wastes a lot of resources, pollutes the environment, but more importantly, the utilization rate of chemical fertilizers With the continuous expansion of the quantity, it will be greatly reduced, and at the same time, it will lead to the crazy growth of corn leaves and even the outbreak of diseases and insect pests, and the phenomenon of lodging is common. Combining various factors, the production cost of corn continues to rise, but the yield cannot be improved, and the quality is gradually declining. , more serious is to cause vicious circles such as soil erosion and soil compaction, which seriously threaten the health of contemporary people and the living environment of future generations
