Last Updated: 2024/11/08, When there is a lack of nutrient elements, the main reasons for the lack of nutrient elements are as follows: the difference or error of effective components in fertilizer is not consistent with the actual amount of fertilizer; the improper operation of fertilizer and fertilization results in precipitation and loss, which makes the proportion of nutrient elements out of balance; soil pH value, soil temperature and poor permeability affect the effectiveness of nutrient elements, so that rose can not effectively absorb nutrients. Therefore, in soil cultivation, as long as we adhere to normal fertilization, it is generally not easy to lack large and medium elements, sometimes due to the rapid growth and high consumption of rose.

When there is a lack of nutrient elements, the main reasons for the lack of nutrient elements are as follows: the difference or error of effective components in fertilizer is not consistent with the actual amount of fertilizer; the improper operation of fertilizer and fertilization results in precipitation and loss, which makes the proportion of nutrient elements out of balance; soil pH value, soil temperature and poor permeability affect the effectiveness of nutrient elements, so that rose can not effectively absorb nutrients. Therefore, in soil cultivation, as long as we adhere to normal fertilization, it is generally not easy to lack large and medium elements, sometimes due to the rapid growth of rose, consuming a lot of fertilizer and water, and not applying fertilizer in time, which can be solved by increasing the frequency and amount of fertilizer supply. It is easy to lack trace elements such as iron, manganese, boron, calcium and magnesium. When lack of iron or manganese, besides increasing the amount of iron or manganese fertilizer, it is more important to adjust the pH value of the soil so that the pH value is between 5.5 and 6.5, so as to improve the activity of iron or manganese. 0.2%-0.5% chelated iron or manganese can be foliar sprayed at the same time for severe deficiency; boric acid and calcium nitrate can be used for foliar spraying for severe deficiency, while boric acid and calcium nitrate can be used for foliar spraying when boron, calcium and magnesium are deficient; the occurrence of cord deficiency symptoms can be reduced by applying a large amount of mature farm fertilizer combined with soil improvement. After the occurrence of nutrient deficiency symptoms, the nutrient elements need to be adjusted for 2-3 weeks or even longer. During the adjustment period, soil detection and leaf color changes are needed to observe the changes of leaf color. After the plant returns to normal growth, it will return to normal fertilizer and water management.
