According to a vegetable farmer, the sweet peppers have not been able to bear fruits in the recent past. Even if they are sitting, the bell peppers are very small. After careful observation, it was found that a lot of sweet peppers that have been sitting on their hands are very long. What causes this?
First of all, when the night temperature is high, a small temperature difference between day and night can cause the flower needle to become longer. Since the winter, many places have not cooled significantly, but the farmers closed the air vents earlier in the afternoon, resulting in higher temperatures in the shed at night, the night temperature is high and can lead to plant leggy, flower buds poorly differentiated, so spent too long is not enough Strange. Therefore, vegetable growers can postpone closing the tuyere, so as to increase the temperature difference between day and night. Generally, the nighttime temperature is maintained at about 13°C, and the temperature difference between day and night is above 10°C.
Second, the lack of boron can cause long needles. At low temperatures, the lack of boron will clearly show the phenomenon of small flowers and long needles. In order to prevent the lack of boron, borax can be used for 1 kilogram, with the water rushed to the ground, you can also spray borax 600 times or 1200-1500 times the speed of boron boron solution.
In addition, insufficient supply of water and fertilizers can also result in longer needles. Due to the low temperature, vegetable farmers generally reduce the frequency of watering and fertilization in order to prevent the ground temperature from decreasing after fertilization. This results in insufficient supply of sweet and sour bell pepper water during the expansion period, which makes the sweet peppers spend too long. In order to prevent the ground temperature from declining too much, the vegetable grower can use the method of pouring organic fertilizer with small water and meet the demand for nutrients when the sweet peppers are bulging.
