Watermelon growing environment, which areas are suitable for planting?

1. Temperature: The optimum temperature for watermelon growth is 25-30℃, and the germination temperature of seeds should be above 65438 05℃. When the temperature is lower than 10℃, watermelon will stop growing, and when the temperature drops to 5℃, watermelon will freeze. 2. Moisture: Sufficient moisture should be provided at seedling stage, vine extension stage and fruit expansion stage. If there is too much water, there may be rotten roots, dead seedlings and rotten melons. 3. Illumination: Watermelon is sensitive to light and can grow healthily under the condition of sufficient illumination and suitable temperature. 4. Soil: sandy loam with deep fertility, good drainage and rich organic matter, suitable for planting soil.

First, the growing environment of watermelon

1, temperature

(1) Watermelon likes temperature and heat resistance, but is afraid of low temperature. 25-30℃ is the optimum temperature for its whole growth period.

(2) The germination temperature of seeds should exceed 65438 0 5℃. If the temperature is lower than 10℃, the seedlings will stop growing, and when the temperature drops to 5℃, they will freeze to death.

(3) After entering the fruit-setting stage and fruit expansion stage, the lowest temperature should not be lower than 65438 08℃, otherwise it will be difficult to set fruit, or even if the fruit is set, it will develop into a thick-skinned, hollow, flat fruit with low sugar content.

(4) When the temperature is within a certain range, if the temperature difference between day and night is large, it is beneficial to the growth of watermelon, especially to the accumulation of sugar in fruits and vegetables.

Step 2: Moisture

(1) Watermelon needs to provide enough water to ensure the growth of melons and fruits at seedling stage, vine extension stage and fruit expansion stage. It should be noted that water should not be excessive, so as to avoid rotten roots, dead seedlings and rotten melons.

(2) It is suggested to use deep ditch sowing, high moisture sowing (planting and transplanting) for planting, or adjust sowing date to make the plants bear fruit before and after the rainy season.

3. Lighting equipment

Watermelon is a short-day crop, which is sensitive to light and develops well under the conditions of high temperature and sufficient light. Specifically, the vines are short and thick, the leaves are thick, the melons and fruits are large, and the sugar content is high.

4. Land

(1) Watermelon has low requirements on soil, and can be planted in different soil types, but sandy loam with deep and fertile soil layer, good drainage and rich organic matter is usually suitable.

(2) Sandy soil has the characteristics of good permeability, rapid heat absorption during the day and rapid heat dissipation at night. When planting, it can avoid rotten roots, rotten vines and rotten melons caused by water accumulation in the field, which is beneficial to the accumulation of sugar in fruits and vegetables.
