Description

Water-saving irrigation system for corn field

Technical Field

The utility model relates to a field irrigation facility, concretely relates to corn field water-saving irrigation system.

Background

In the north of China, the rainfall is less, and the method is not suitable for planting rice. And the corn has better drought resistance and is the most main planting crop for farmers in the north. Corn can be used in food processing and feed processing, and is an important food crop. Although corn has good drought resistance, watering and irrigation are also needed in an important part of the growth of corn. One corn strain consumes about 2kg of water every day in the flowering period, 3-4 sides of water every mu every day, and 250-350 sides of water in the whole growth period. Different breeding corn has different water requirements. The period from 10 days before castration to 10 days after castration is the period of corn which needs the most water and is most sensitive to water in life, and is called as the 'critical period of water demand'. Irrigation is carried out during this period. Corn is watered for 3-4 times in a lifetime, which varies from area to area and according to the specific conditions. The irrigation method is mainly ditch irrigation and furrow irrigation in China at present, and recently, the irrigation method and the furrow irrigation are developed and utilized, and the latter two methods not only save water but also irrigate uniformly. In the flowering period and before tasseling of the corn, if manual walking or machine equipment walking watering is realized, the branches and leaves of the corn are easy to collide, so that the flowers, tassels and the like of the corn are damaged, and the result is influenced. Because northern water resources are precious, water conservation has important significance to farmers per se, but the premise of water conservation is to ensure that the corns are sufficiently irrigated so as not to influence the yield of the corns.
