Causes of shorter and darker needles

“I don’t know why, recently, the aubergine needles in this shed are not the same as the original ones, and they are short and dark. There are certainly many abnormal eggplants that grow out of this kind of eggplant.” Recently, when interviewed in the Gongpeng District, Jitai Township, Shouguang City, there was more than one. A vegetable farmer reported to reporters.

In past years, there were abnormalities in the eggplant flower needles, but it was generally in the deep winter season. Due to the low temperature in the shed, the differentiation of flower buds in eggplants is affected, flower buds are poorly differentiated, and flower needles become dark and short. The temperature is still high, and the temperature and humidity inside the arch are suitable. It should not be caused by poor flower bud differentiation.

So, in addition to flower bud differentiation, what are the reasons that can cause the long eggplant needle to become darker and shorter?

The first is the shortage of nutrient supply. Most of the eggplants in the shed now enter the late growth stage, and the plants are aging earlier. The supply of nutrients is insufficient, resulting in darker, shorter needles. In view of this situation, nutrition should be given to long eggplant in time, and the total water-soluble fertilizer such as Shifang Run and Leba can be sprayed with the water, and full-nutrition type foliar fertilizer can also be sprayed on the leaves, such as Fang Run and Jia K. The effect is good.

Second, due to lack of boron. In general, the lack of Boron in the long eggplant will cause the flower needle to darken and shorten. In response to this, the vegetable farmer should be reminded to seize the time to spray 1200 times the speed of Sorrel, the effect is good.

Then there is the injustice caused by drought and flood. If the soil in the greenhouse is too dry or too wet, severe changes will often lead to plant root injury and weakened plant growth, resulting in blackening and shortening of flower needles. Therefore, the watering should be based on soil moisture, must not water by day. When flooding, avoid flooding and avoid rooting.
