A Complete Analysis of the Key Points of Chestnut Tree Planting Techniques
Chestnut is the fruit of the Fagaceae family, and has the reputation of the "king of dried fruits" in our country, with a cultivation history of more than 2500 years in our country. Chestnut contains very rich nutrients, and the sugar and starch content in the chestnut fruit is extremely high, with the effects of tonifying the kidney and strengthening the spleen, and strengthening the body. There are many people in our country now growing chestnuts, but there are some key points in chestnut tree planting that many people overlook. Below, let the editor introduce the key points of chestnut tree planting techniques to you!
1. Plowing the Woodland
Chestnut orchards should be plowed appropriately, usually with the intensity controlled according to the age of the chestnut. Young orchard plots are mainly shallow-plowed, while fruiting orchards should be deep-plowed with expanded holes, adding subsoil, improving the soil, and promoting root growth. The deep plowing depth of mature orchards must not be less than 30 cm, and care must be taken not to damage the roots during deep plowing. During deep plowing, a comprehensive cleanup should be carried out to ensure that soil and water conservation facilities are intact, prevent soil and water loss, and remove harmful substances from the soil.
2. Reasonable Fertilization
The fertilizer for chestnut is mainly organic fertilizer, with as little chemical fertilizer as possible, and if possible, no chemical fertilizer at all. Because chemical fertilizer will harm the roots of the fruit trees, and in severe cases burn the roots and cause various pests and diseases. When fertilizing, carry out ring-shaped fertilization along the tree canopy, and dig the fertilization ditches well. Control the amount of fertilizer according to the tree age, and immediately earth up after fertilizing to improve the soil's fertilizer-retaining capacity, which is conducive to root nutrient absorption and enhances the tree's growth vigor.
3. Bark Scraping and Whitewashing
Bark scraping and whitewashing are mainly aimed at fruit trees aged 10 years or more, and generally the start time is after harvest, but temperature must also be taken into account; for areas with lower temperatures, it should be delayed to early spring. The rough bark and peeling bark on fruit trees are the main places where pests and disease bacteria overwinter, so timely bark scraping can disrupt the overwintering of pathogens and reduce the disease incidence of fruit trees. Take the scraped bark out of the orchard in a centralized way for burning, then whitewash the lower part of the trunk to prevent termites or pathogens from invading.
4. Shaping and Pruning
Because the chestnut tree is a large tree type, shaping and pruning work is very important for chestnut trees. For trees around 5 years old, the sprouting branches and lower branches at the base of the fruit tree should be cut off. Then remove dead, dying, and pest- and disease-affected branches, and also promptly thin out overlapping branches that are too dense or too long. Prevent the fruit tree from being too closed off, which affects chestnut flowering and fruiting. For old trees, cut off the old branches, then cultivate new main branches to promote the formation of a new canopy, restore growth vigor, and increase yield.
5. Freeze Prevention Management
After entering winter, the growth vigor of chestnut trees gradually weakens and they begin to shed leaves, especially in some areas where winter temperatures are below zero, where chestnut trees will suffer freeze damage. This affects the overwintering of chestnut trees, so before the chestnut trees shed their leaves, we should loosen the soil around the tree disk and cover it with plastic film, then apply sufficient base fertilizer and earth up in time. If the soil is too dry, water appropriately to improve the cold resistance of chestnut trees and ensure that they can successfully overwinter.
The above is a brief introduction to the key points of chestnut tree planting techniques. Growing chestnut trees is not as simple as everyone thinks; chestnut growth is relatively slow, and it may take about 4-5 years to enter the full fruiting period. So there are certain techniques to growing them, and I hope everyone understands these planting basics well before planting. That is all for today's introduction. This article is for reference only.
