What about potassium deficiency in tomatoes? Control methods of potassium deficiency in Tomato

Symptoms of potassium deficiency in tomato

In the early stage of tomato growth, the symptom of potassium deficiency begins with the leaf margin, which is green and withered, and the mesophyll between the veins is seriously chlorotic. In the fruit expansion period, the leaves near the ear are most likely to show the symptoms of potassium deficiency, first showing chlorosis of the leaf margin, and then drying up, like scorching. The fruits of potassium deficiency plants are poorly colored, and green fruits are easy to appear if there is too much nitrogen at the same time of potassium deficiency. In the case of large amount of watering and excess nitrogen, if the potassium supply is insufficient, the leaves are dark green and soft, which is easy to be infected with various bacteria, while under the condition of drought, the leaves are dark green, and the drought tolerance is obviously reduced. accompanied by flower and fruit drop, the fruit is small, angular and poor coloring.

② in the peak growth period, fruit development needs more potassium, at this time if the supply of potassium is not sufficient, it is easy to occur symptoms of potassium deficiency.

③ when the use of lime fertilizer is too much, it affects the absorption of potassium by the plant, and it is also prone to potassium deficiency.

When the sunshine of ④ is insufficient, it is easy to occur when the temperature is low, and when the ground temperature is low, the potassium absorption of tomato is weakened, and potassium deficiency is easy to occur.
