Q: At present, citrus grows well. How should we strengthen the management of citrus in the later period?
A: Strengthening the management of fertilizers and water in the middle and later stages is an important guarantee for the improvement of citrus quality. Therefore, the most important measure is timely potassium supplementation.
Q: Why do you need to pay special attention to potassium supplementation in the late period of citrus?
Answer: The effect of potash on citrus is too great. There are mainly the following points.
First, the increase in demand for potassium during citrus fruit enlargement. The lack of potassium results in smaller fruit, higher acidity, poor coloration, and even fruit cracking.
Second, the lack of potassium also caused the weakening of tree vigor, poor root growth, and reduced drought resistance.
Third, the lack of potassium in citrus, not only yield is not high, but the quality decline.
Q: What are the effects of potassium supplementation on potassium-depleted citrus trees?
A: After adding potassium to the potassium-depleted citrus tree, the fruit will be large and heavy, the soluble solids content will increase, the vitamin C content will increase, the acidity will decrease, the flavor will be rich, the peel will be hard, the color will be deepened, and the cracking fruit and wrinkles will decrease before harvest. The organization is full and the ability to fight drought increases.
Q: How is potassium deficiency in citrus trees caused?
Answer: There are many reasons for the lack of potassium in orange trees. There are mainly the following aspects.
First, citrus trees are usually planted on acidic soils. Generally speaking, the content of available potassium in the southern acid soil is very low. This is an external cause. The citrus tree is also a fruit tree with good potassium. Large amounts of potassium are required for internal reasons.
The second reason is that the amount of organic fertilizer is insufficient and the source of potassium supplement is also a reason.
Third, the habit of partial application of nitrogen fertilizer by orange farmers has resulted in unbalanced nutrient input of fertilizers, which has affected the absorption of potassium by citrus trees.
The fourth is the lack of water drought in the late mid-summer citrus grove, affecting the absorption and utilization of potassium in the root system.
Q: What measures should be taken to prevent potassium deficiency in citrus trees?
Answer: Generally, when applying basal fertilizer in September, pay attention to the application of farmyard manure or cake fertilizer containing more potassium. Adult mandarin trees use about 2 kilograms of perishable cake. At the same time, pay attention to the foliar spray potassium fertilizer, can use 0.2% ~ 0.3% potassium dihydrogen phosphate spray 2 ~ 3 times, spray every 7 to 10 days.
Q: Is there any harm in overdosing potassium?
A: The application of potash can not be excessive, but the excess is counterproductive. Such as causing thick skin, poor coloration, juice, soluble solids content is low, the fruit is mature and green, and susceptible to brown rot and gum disease.
Expert Tips:
â— Potassium in later stages of citrus can not only increase yield, but also improve its quality.
â— Soils grown in citrus are potassium-depleted acidic soils that are external causes, while citrus fruits are high in potassium.
â— Potassium supplements in citrus trees are good for balanced fertilization and nutrient absorption and utilization. (Author: Chen Lun Shou)
