When interviewed in the ancient city streets and rice fields in Shouguang City, the reporter saw that a few of the tomatoes grown by the vegetable growers were still immature, but they were no longer watered and fertilized. The main reason for this situation is that these vegetable farmers have a misunderstanding in understanding: The tomatoes are now completely fruitful, and the demand for water and fertilizer is not large, and then watering and fertilizer is not only a waste of fertilizer, but also reduce the greenhouse. Temperature affects the speed of fruit ripening. Reporters found in these greenhouses, stopped the watering of the tomatoes, the upper three ear hollow fruit significantly increased, yield decreased, quality decline. While still continuing to irrigated greenhouse tomatoes, these problems did not arise. The vegetable farmers should realize that, although apparently, the fruit growth of the tomatoes has basically stopped, in fact, the fruit continues to expand and the internal pulp is still growing, but the rate of growth of the tomatoes is slow. Moreover, after the tomato enters the color-changing period, the seed matures. At this time, the nutrition needed is not less than when the tomatoes are inflated. If water and fertilizer are stopped prematurely, the water and nutrients in the soil cannot meet the needs of tomato growth, and the tomato yield, especially the output of the fruit of the top one ear, is greatly affected. Therefore, it is necessary to remind the vegetable farmers that the top dressing should be controlled at the time when the second ear of the tomato's uppermost fruit begins to turn color, so as to ensure the moisture and nutrition in the soil and promote the increase of the tomato yield.
