Summer topdressing methods and technical points for eggplant
Furrow application. Vegetable growers have become accustomed to applying chemical fertilizer by broadcasting it with irrigation water, but this method is not suitable during the hot summer season. Because the temperature is relatively high, when chemical fertilizer is applied with irrigation water, a large amount of ammonia volatilizes, which reduces the effect. This is especially true for ammonium bicarbonate, which is more likely to cause ammonia poisoning in eggplant. Applying it in furrows or burying it in holes gives the best results...

What are the correct methods for fertilizing eggplants?
Seedling-stage fertilization: To grow seedlings with thick stems, short internodes and well-developed roots, the seedbed soil must be fertile. On 11.3 sq m of seedbed soil, apply 200 kg of decomposed organic fertilizer and 0.5 kg each of superphosphate and potassium sulfate, and mix the seedbed soil and fertilizers evenly. You can also apply 100-150 kg of mixed human manure and 1 kg of NPK compound fertilizer.

Cause analysis and control methods for celery petiole cracking
Celery petiole cracking mainly shows as the stem base splitting open together with the petiole. The first cause of cracking is boron deficiency; the second is growth being hindered under low temperature and drought conditions. In addition, sudden high temperature and high humidity, with the plant absorbing too much water, cause the tissue to fill with water rapidly, which can also cause cracking. Control methods: first, apply...
