This article explores the physiological water requirements and critical periods of potato crops, and how to achieve high yield and quality potato production through reasonable water management and simulation model research. Farmers, agronomists, agricultural engineers, farmers and agricultural scientists will find here key information on potato cultivation.
Potatoes (Solanum tuberosum) are an important food crop that are vital to agricultural industries around the world. This article will take an in-depth look at the physiological water requirements and critical periods of potato crops, and how to manage these factors to achieve higher yields and quality.
- Physiological water requirements of potato crops
Physiological water requirements of potato crops refer to the water requirements of potato plants at different growth stages. During the growth of potatoes, water plays a vital role in the plant’s physiological activities and nutrient absorption. Potatoes have different water requirements at different stages of growth.
Seed germination period: Potato seeds need sufficient water during the germination period to promote seed germination and root growth. If the soil moisture is insufficient, seed germination will be inhibited, affecting the entire growth process.
Seedling stage: The potato seedling stage is one of the key periods for potato growth. At this time, the plant needs sufficient water to support the growth of leaves and the absorption of nutrients. Insufficient water will cause slow growth in the seedling stage and affect subsequent growth and yield.
Vegetative growth phase: The vegetative growth phase of potatoes is the main stage of potato growth. At this time, the plant needs a lot of water to support the growth of stems and leaves and flowering and fruiting. Insufficient water will cause plant growth to be restricted and yield to decrease.
Potato formation stage: Potato formation stage is the final stage of potato growth. At this time, the plant needs an appropriate amount of water to support the expansion of tubers and the formation of mass.
- Critical period for potato crops
The critical period of a potato crop is the time during potato growth when water requirements are most sensitive. During these periods, insufficient moisture supply can seriously affect potato growth and yield.
Seedling stage to early vegetative growth period: This period is one of the key periods for potato growth. The plant needs sufficient water to support the needs of the seedling stage and early growth. If there is insufficient water, plant growth will be inhibited and yield and quality will be affected.
Mid-vegetative growth period: During this period, potato plants enter the peak growth period of stems and leaves and require a large amount of water to support the growth of stems and leaves and flowering and fruiting. Insufficient water will cause plant growth to be restricted and yield to decrease.
Early tuber stage: At the early stage of tuber stage, potato plants need an appropriate amount of water to support tuber enlargement and mass formation. If the water supply is insufficient, the growth of tubers will be restricted, affecting potato yield and quality.
- Moisture management during critical period
Physiological water requirements and critical periods of potato crops are critical to achieve high yield and quality potato production. At different stages of potato growth, the demand and sensitivity to water are different. Therefore, reasonable irrigation management and water regulation are of great significance to the growth and yield of potatoes. Farmers and researchers should strengthen research on the physiological water requirements and critical periods of potato crops to improve potato production efficiency and quality. At the same time, the government and agricultural departments should also strengthen guidance and support for potato planting and promote the sustainable development of the potato industry.
