Detailed Explanation of Key Techniques for Tomato Planting and Irrigation Management
Tomatoes begin to be watered after the seedling-stabilizing stage when fruit has set (when the first fruit is about the size of a walnut). Over the whole growing season, 3--4 waterings are given. Generally, one watering is given at the seedling stage as a transplanting and seedling-lifting watering. Water is then withheld until the first fruit cluster swells to where the young fruit is 2--4 cm in diameter, at which point the second watering is given. After that, depending on the condition of the seedlings and the moisture level of the soil, irrigation is carried out once every 10--15 days, with 3--4 irrigations over the whole growing season, each irrigation applying 60--...
Tomatoes begin to be watered after the seedling-stabilizing stage when fruit has set (when the first fruit is about the size of a walnut). Over the whole growing season, 3--4 waterings are given. Generally, one watering is given at the seedling stage as a transplanting and seedling-lifting watering. Water is then withheld until the first fruit cluster swells to where the young fruit is 2--4 cm in diameter, at which point the second watering is given. After that, depending on the condition of the seedlings and the moisture level of the soil, irrigation is carried out once every 10--15 days, with 3--4 irrigations over the whole growing season, each irrigation applying 60--110 cubic meters per mu. Irrigation should be done by gentle furrow flow; flooding irrigation is strictly prohibited to avoid fruit rot and the occurrence of diseases. At the same time, intertillage should be strengthened to prevent stunted seedlings caused by lack of water. For fields with more severe drought, furrows should be opened early to divert water and raise soil moisture. The second watering should closely follow the first, and afterward the third watering is given when the green fruit reaches the swelling stage according to the moisture conditions, with later waterings given as the moisture conditions require.
