Latest Detailed Explanation of the Causes of Nutrient Deficiency in Luffa and Preventive Measures

In the cultivation and management of luffa, various reasons such as watering and fertilizing often lead to a deficiency of trace elements in the plants, which causes a decline in plant growth, and both yield and quality are affected. So what are the causes of nutrient deficiency in luffa? Follow the editor to take a look.

1. Causes of iron deficiency

When the soil is alkaline, too dry or fruiting, or when the temperature is too low or copper, manganese, phosphorus and other elements are excessive, the root system's absorption of iron is affected, thus causing iron deficiency in the plant. Therefore, the soil should be kept moist to avoid being too dry or too wet, and the application of alkaline fertilizers should also be controlled. When the plant is deficient in iron, a 0.1-0.5% ferrous sulfate aqueous solution can be sprayed on the leaves in time, which can quickly restore the plant from iron deficiency symptoms.

2. Causes of zinc deficiency

When the soil is alkaline, too high a zinc content prevents the root system from absorbing it, and too strong light intensity can also easily lead to zinc deficiency. When phosphate fertilizer is excessive, it also affects the absorption of zinc. Therefore, do not apply excessive phosphate fertilizer. If zinc is deficient, a 0.1-0.2% zinc sulfate aqueous solution can be sprayed on the leaves.

The main cause of copper deficiency is alkaline soil or soil salinization, which seriously affects and hinders the root system's absorption of copper. Therefore, when the soil is alkaline, acidic fertilizer can be applied to neutralize the soil, and at the same time a 0.03% copper sulfate aqueous solution can be sprayed on the leaves, which can very well alleviate the plant's copper deficiency symptoms.

4. Causes of boron deficiency

Soil drought, alkalinity, poor fertility, and excessive application of potassium fertilizer all affect the absorption of boron. Water should be applied in a timely manner, more organic fertilizer should be applied to improve the fertility level of the soil, and potassium fertilizer can also be added. An appropriate amount of potassium fertilizer can be added to the base fertilizer, or in the middle and late stages of plant growth, a 0.12-0.25% boric acid or borax aqueous solution can be sprayed on the leaves.

5. Causes of manganese deficiency

Reasons such as low soil organic matter content, alkalinity, and high salt concentration can easily lead to manganese deficiency. Therefore, chemical fertilizers should be applied scientifically, and do not apply excessive chemical fertilizer, which causes the soil concentration to become too high. Pay attention to applying more organic fertilizer, increasing the soil organic matter content, and improving soil vitality.
