Why is it common for growers to spray lime on citrus trees?

If you spray lime water on the mandarin, it can form a white protective layer on its surface, so that it can reflect the sunlight and play the role of sun protection, so as to avoid the mandarin orange being exposed to the sun for a long time and being sunburned to form scars, and it can also play a role in preventing insects and pests.

Spraying lime powder on citrus trees is to protect from the sun, the sunlight will reflect on the white object, so that the surface temperature of the peel is not too high, and the lime powder can also prevent insects and bites.

The reason for coating lime on citrus is that light calcium carbonate has a certain degree of promotion of peel development, hardening the feel of the fruit, and has a certain benign effect on storage and transportation.

This is to make the ripe color of the citrus more beautiful and more evenly distributed, so it is sprayed with this kind of thing, and the quality is better.

Poor concentration or dosage will affect the tree potential of citrus. 1 2-year-old young trees, focusing on cultivating each branch tip, fertilization to the principle of thin fertilizer from violet, and more application before and after the shoots. One month after planting, the new roots begin to move, and thin water and fertilizer can be applied.

Apply water-soluble fertilizer once before each new shoot germination 10-15 days before the new shoot germination and during the new shoot stop growth period, and strive to extract 3 or 4 strong shoots a year.

First-fruiting trees (3-4 years old) are repeated in winter, before spring, and before autumn. The principle of not doing it before the summer. That is, from December to January of the following year, fertilizer is applied after fruit picking, which is needed for the spring shoot period, and water-soluble fertilizer is the main one.

In February, the strong trees before the spring shoots were not applied, and the weak trees were applied with water-soluble fertilizer once to promote the growth of spring shoots. In May and June, no fertilizer is generally applied to control the growth of summer shoots. Re-apply before autumn, mainly with fast-acting water and fertilizer, the purpose is to promote the autumn shoots, lay a good foundation for the second year to increase production, 8-10 months can be applied 1-2 times of water-soluble fertilizer to strengthen shoots and fruits.

Middle-aged fruiting trees are fertilized 4-5 times a year, mainly before and after fruit picking, before spring shoots, and before autumn shoots. Late-maturing seeds, medium-maturing varieties with more fruits, and weaker fruiting trees should be applied before fruit picking; Early-maturing seeds and medium-ripening seeds with little fruiting amount are applied after fruit picking. It is best to apply ponkan orange before fruit picking, and orange orchards with less rain and no irrigation conditions should also be applied early, mainly with water-soluble fertilizer in Ribery Yanwo, so as to restore the tree potential and protect the leaves for winter.

Hello, quicklime will be sprayed on the roots of the citrus tree, if the amount is not very large, it will not affect the tree. Regulating effect on soil pH. In general, the pH of the soil suitable for plant growth is between pH values.

The requirements for soil pH for citrus growth are not too strict, as long as the pH value of the soil is stable between, it can be more suitable for growth. However, the pH of the soil suitable for citrus growth is internationally recognized as 6. Therefore, if the pH exceeds this range, it needs to be adjusted, especially if the soil acid is too high, it needs to be adjusted, then, sprinkle an appropriate amount of lime powder in the soil of acidic soil, you can effectively adjust the pH of the soil, which is conducive to the growth of citrus.

Summary. Hello, dear, spraying lime water may not do much to prevent fruit cracking. Citrus fruit cracking has a number of factors, one is the cause of climate instability, such as continuous drought after rain or continuous rain after the sun exposure, soil moisture increase, fruit nitrogen, improper use of hormones, calcium deficiency and so on may lead to fruit cracking.

Daily fertilization should be done routinely, reasonable watering and control the use of nitrogen fertilizer and hormones, and pay attention to calcium supplementation can improve fruit hardness and prevent fruit cracking.

Can citrus be directly applied with lime water?

What I asked was: The citrus soil is too acidic, can it be watered directly with lime?

Please wait a minute, dear.

Good. Most of the citrus orchards in southern China are planted in hilly acidic soil, although citrus cultivation can grow normally in the soil of pH 4 8 8 5, but it is appropriate to be close to neutral (pH 6 0 6 5). The soil is acidic, and it is easy to dissolve and lose trace elements such as phosphorus, calcium, magnesium, boron, molybdenum, and zinc in the soil, so it is okay to apply lime powder or limestone powder to the acidic soil of citrus orchards, which can neutralize its acidity.

What I asked was: The citrus soil is too acidic, can I water the fruit trees directly with lime?

Yes, it just happens to neutralize the acidity of the soil, which is what I have been saying above.
