Etiology, Prevention and Control of Peach Yellow Plant Disease in Protected Areas
I. Reasons 1. Reasons for iron deficiency in Peach trees due to iron deficiency protection sites: 1 Planting density is high, and some even reach 1 meter and 0.8 meters. Each tree occupies a small area of ​​nutrients, roots and roots cross each other, and soil is released. The iron ions cannot satisfy the absorption of the roots. 2 After Peachtree results, the load is large, organic nutrients preferentially supply fruit growth, root growth is inhibited, the ability of the roots to secrete acidic substances is weakened, and iron ions in the soil cannot be effectively absorbed by the roots. 3 Influenced by the pH of the soil, iron ions in neutral and alkaline soils are easily fixed by hydroxide ions, forming insoluble iron hydroxide, which can not be absorbed by the roots of peach trees and cause iron deficiency symptoms, and mainly occurs in the new Leaves on. 2. Before pruning fruit after pruning, a variety of organic and inorganic nutrients were used to supply fruit growth and root growth was inhibited. After the fruit is harvested, the roots are in desperate need of the leaves to supply organic nutrients. At this time, heavy retrieving and pruning are performed, and a large number of vegetative shoots and leaves are lost in the aboveground parts, resulting in insufficient supply of nutrients for underground root growth, resulting in the death of capillary roots due to excessive pruning. Well absorbed nutrients, resulting in insufficient supply of nutrients above the ground. 3. Many chemical fertilizers, organic fertilizer less long-term application of chemical fertilizers, resulting in soil compaction, poor physical and chemical properties, soil barren, poor structure, low organic content, soil bacteria decreased, affecting the decomposition and release of soil nutrients. Soil viscosity, poor permeability, affect the growth of the root system. 4. Root diseases Peach tree root diseases are another important cause of peach leaf yellowing. Plants suffer from root cancer disease, purple feather disease, root decay and so on, which affect plant root growth and hinder root system nutrients and moisture. Absorption, resulting in debilitating tree vigor, severe plant death. II. Prevention 1. Control of iron deficiency 1 Sparse planting: The planting density is 2.5 meters, 1 meter to 3 meters, and 1 meter. It increases the range of soil that the root absorbs nutrients and moisture, so that the iron ions in the soil can satisfy the absorption of roots and give plant growth. Create a good growing environment. (2) Reasonable load: According to the situation of peach, the yield per mu is generally no more than 3,000 kg. Then the yield per mu is decomposed into each tree. The calculation formula for the amount of fruit per tree is: The amount of fruit left (fruit number) Yield per plant (kg)/fruit weight (kg). 3 Spray foliar fertilizer: Spray the foliar with 0.1% ferrous sulfate and rice vinegar 500 times. 4 Infusion control: When there are individual branches with iron deficiency, they are bottled with 0.1% ferrous sulfate and 0.5% acetic acid mixture to hang on the tree, and the iron-deficient shoots are directly inserted into the bottle. It is also possible to use the above-mentioned mixed solution in an infusion bottle, hang it upside down on the branch, make a hole in the trunk, and infuse it with a medical infusion set. 2. After fruit picking after light fruit cutting, the resulting branches are pruned, mainly sparsely, and the back branches, upright branches, thin and weak branches, disease and insect branches, and cross branches are removed, combined with artificial topping, twisting, and taking branches. Keep certain nutritional branches to balance the tree potential. 3. Reasonable fertilization; Increase the use of high-quality organic fertilizers, control the application of fertilizers to soils with heavy soil mass, increase the use of high-quality organic fertilizers in autumn, increase soil permeability, and improve soil physical and chemical properties. If the soil is more viscous, fill some river sand in the colonization pit, which has a certain effect. 4. Prevent root diseases. Inspect the seedlings for disease. Use a 1% copper sulfate solution or 2% lime water to soak the root for 1 minute. K-84 (Canaconing) can also be used to dip the root for 5 minutes, and then colonize if found. For cancerous plants, nodules were removed with a quick knife and disinfected with 1% copper sulfate 100 times.
