First, the cause of Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
1. Mainly due to the high density of planting, the large amount of load after the result, the pH of the soil caused by the lack of iron in the roots of the peach trees or the inability to absorb iron by normal. Linyi Fertilizer Network Copyright

2. After the fruit is harvested, the fruit is over-weighted. After the fruit is harvested, it is retracted and trimmed. A large number of nutrient shoots and leaves are lost in the ground, which causes insufficient nutrient supply of underground root growth, affecting the absorption of iron by the root system, resulting in insufficient supply of nutrients in the upper part. .

3, more fertilizer, less organic fertilizer. Long-term large-scale application of chemical fertilizers, resulting in soil compaction, poor physical and chemical properties, poor soil, poor structure, low organic content, reduced soil active bacteria, affecting the decomposition and release of soil nutrients. The soil is sticky and poor in permeability, which affects the growth of roots. Linyi Fertilizer Network Copyright

4. Root diseases: The root disease of peach trees is another important cause of the yellowing of peach trees. The plants suffer from root cancer, purple feather disease, root disease, etc., affecting the root growth of the plants, and the roots are resistant to nutrients and water. The absorption causes the tree to be thin and weak, and when the plant is dead, the plant is dead. Linyi Fertilizer Network Copyright

Second, the prevention and treatment of Linyi Fertilizer Network Copyright

1. Prevention and treatment of iron deficiency: (1) thin planting; (2) reasonable load; (3) spraying foliar fertilizer, spraying 0.1% ferrous sulfate and rice vinegar 500 times solution to the foliage. (4) Infusion control, when there are individual shoots with iron deficiency on the plant, use 0.1% ferrous sulfate and 0.5% acetic acid mixed liquid in the bottle to hang on the tree, and insert the iron-deficient shoots directly into the bottle. The above mixed liquid can also be used in the infusion bottle, hanging upside down on the branch, making a hole in the trunk, and infusing with a medical infusion set.

2. After picking the fruit, after lightly cutting the fruit, the result branches are trimmed to remove the main branches, erect branches, thin branches, diseased branches, and penetrating branches, and artificial picking, twisting, taking branches, etc. , keep a certain number of vegetative branches to balance the tree.

3. Rational fertilization, increase the application of high-quality organic fertilizer, control the weight of the fertilizer and soil, and increase the application of high-quality organic fertilizer in the autumn to improve the permeability of the soil and improve the physical and chemical properties of the soil. If the soil is more viscous, filling some river sand in the planting pit has a certain effect. Linyi Fertilizer Network Copyright

4, prevention and control of root diseases: check whether the seedlings are diseased, soaked with 1% copper sulfate solution or 2% lime water for 1 minute, or K-84 (cancer Corning) soaked for 5 minutes, after planting, if found For root cancer plants, the nodule was removed with a sharp knife and disinfected with 100% copper sulfate solution.
