The latest symptoms of boron deficiency in cauliflower and its control measures

Cauliflower is one of the common vegetables in our life. It is sensitive to trace elements when it is planted. If it lacks boron in the growth process, it will have a great impact on its growth. So what is the reason for boron deficiency in cauliflower? How to prevent and cure it? Let's get to know it.

1. Symptoms of boron deficiency

After boron deficiency, cauliflower will appear stem and leaf stiffness, easy to break, top leaf growth will be blocked, leaves will bend outward, deformed, and the lower leaves will gradually turn yellow. Its stems and leaves will also gradually lignify or crack, the new leaves will dry up, and the bouquet will gradually turn brown. In the later stage, the stem is hollow, the flower head has obvious macula, the best inflorescence dies, the root system is short and thick, inedible, and the commodity decreases, which affects the economic income of farmers.

2. Causes of boron deficiency

There are many reasons for boron deficiency in cauliflower. Soil drought will affect the absorption of boron by roots. Less organic fertilizer or too much nitrogen fertilizer in soil will also hinder the absorption of boron by roots, resulting in boron deficiency. Excessive application of potash fertilizer will also affect the absorption of potash fertilizer, which is easy to cause boron deficiency. In the high temperature environment, the transport of boron in the plant will be hindered, so it will cause local boron deficiency in the plant.

3. prevention and control measures

An appropriate amount of boron-containing fertility can be added to the base fertilizer, generally 1-1.5 kg of borax per mu, which can meet the boron demand of the plant during the whole growth period. Watering should be done in time during drought so as not to affect the absorption of root system, and more organic fertilizer or farm manure should be applied when topdressing, which can not only fully supplement all kinds of nutrients, but also maintain soil permeability and water conservation and fertility. In the case of boron deficiency, foliar fertilizer can be sprayed with low concentration borax solution once a week for 2-3 times in a row, which can alleviate the symptoms of boron deficiency.
