Problems solved by technology

However, due to the uneven distribution of rainfall in the middle and low-yielding fields, there are frequent spring and summer droughts, it is difficult for crops to produce full seedlings, and the growth is restricted, which affects the yield and quality of crops
Planting corn on low- and medium-yield fields severely restricts water and fertilizer management, resulting in low yield per unit of corn, unstable total yield, poor quality, low efficiency, and low farmers' income

Abstract

The invention relates to a corn sprinkling irrigation precision management and water and fertilizer optimal control mode for medium and low-yield fields. A semi-fixed sprinkling irrigation system is used during irrigation, and the semi-fixed sprinkling irrigation system comprises a water source project, a pivot head, a water distribution pipe network, a water irrigator and a control measurement and protection device. A corn planting method matched with the semi-fixed sprinkling irrigation system comprises the first step of soil preparation, the second step of base fertilizer application, the third step of seed drying in the sun, the fourth step of sowing, the fifth step of irrigation, the sixth step of field crop management and the seventh step of harvesting. Utilization conditions of irrigation water can be effectively controlled, and the yield and the total yield of corn are increased; requirements of the land area, terrains and the soil texture conditions are low, and the adaptability is high; an irrigation system can be operated in a unified mode according to water requirement laws and fertility requirements of the corn in different growth periods, a large amount of labor can be saved, management is facilitated, and machine harvesting, pesticide spraying and the like are also facilitated.

Description

technical field [0001] The invention belongs to the field of water-saving irrigation, and in particular relates to a precision management and water and fertilizer optimization control mode of corn spray irrigation in low- and medium-yield fields. Background technique [0002] Semi-fixed sprinkler irrigation is the irrigation technology with the highest utilization rate in my country at present. Its working principle is to use some power equipment to increase the water pressure, and then use the set height to irrigate the water to the required area through the distance drop. Among them, the water turns into fine water droplets in the air through the nozzle, so that the coverage area will be wider and more uniform, and the effect of saving water resources is remarkable, which is suitable for some large-scale farmland. [0003] Corn is the third most important food crop in the world, after wheat and rice. However, due to the uneven distribution of rainfall in the middle and l...
