Detailed Explanation of Chestnut Tree Management Methods and Technical Points
Chestnut is a relatively common nut in daily life, and it also has a wide planting area in China, with even large areas of wild chestnut trees in the south. Now the demand for chestnuts is growing, and China's planting area is gradually expanding. Chestnut cultivation is not as simple as everyone imagines. Because after planting chestnuts, management work must be done well to ensure normal growth of the chestnuts. Below, the editor brings you the management methods for chestnut trees. Let's take a look together!
1. Loosening Soil and Expanding Planting Holes
In the autumn of the same year after planting, soil loosening work should be carried out, and the depth of soil loosening must not be less than 30 cm. When loosening the soil, observe the root distribution of the chestnut tree. Trees with shallow and numerous roots should be loosened a bit shallower. Conversely, deep cultivation can be used. When loosening the soil, pick out the stones, then apply base fertilizer. Then about 3 years after planting, appropriately expand the holes. On the basis of the original planting holes, expand at least 50 cm outward in all directions. When expanding the holes, be careful to separate the topsoil, pick out the stones inside, then mix the fertilizer with the topsoil and backfill. After backfilling, it should be slightly higher than the ground. When expanding the holes, prevent the chestnut roots from being injured, which would affect nutrient absorption.
2. Intertillage and Weeding
Intertillage and weeding work is very important for the growth and development of chestnut trees, because during the young tree stage, the root capacity is not yet developed enough, nutrient absorption is weak, and the threat from weeds is relatively great. Therefore, during the growth of chestnut trees, intertillage and weeding work should be carried out at least twice a year. Intertillage can not only effectively remove weeds, but also improve soil aeration and moisture conservation capacity. It promotes root respiration and nutrient absorption. When weeding, be careful not to damage the tree roots. When using herbicides, pay attention to the dosage to prevent adverse effects on chestnut trees. The removed weeds can be turned into the soil as green manure.
3. Reasonable Intercropping
The spacing between chestnut trees is relatively large, so we can reasonably intercrop between chestnut trees. The intercrop crops should be selected from those that are short-stemmed, have a short growth period, and require little fertilizer and water, and it should be ensured that they can improve soil fertility, improve soil structure, and do not share common pests and diseases with chestnuts. For example, peanuts, peas, etc. After chestnuts have been planted for 2-3 years, reasonably control the density of intercrop crops. And as the chestnut trees grow and the tree shape expands, slowly increase the planting density of intercrop crops until intercropping is terminated. Mature crops can be directly turned into the field as green manure, and if the scale is large, they can also be harvested and sold on the market.
4. Water and Fertilizer Management
Chestnuts have strong adaptability, but if you want to achieve the goal of high yield, you still need to ensure sufficient nutrients. In many places, the soil is relatively barren and low in nutrients. This causes no fruit to be produced even after several years of planting, and it also reduces people's enthusiasm for planting chestnuts. So when planting, we should not only choose fertile soil, but also do a good job in topdressing. During the planting process, the number of topdressings each year must not be less than two. And the nutrients in the fertilizer should be reasonably allocated to ensure sufficient and comprehensive nutrition. When the soil is too dry, water in time, but small droplet drip irrigation should be the main method. The amount of water should not be excessive. When there is too much standing water or on rainy days, pay attention to drainage.
The above is a brief introduction to chestnut tree management methods. The growth period of chestnuts is relatively long, but they bear fruit many times, and after planting once, they can be harvested continuously for many years. It is a crop with relatively high economic value, but during the chestnut growth period, everyone needs to do a good job in management to ensure healthy growth of the chestnuts. Therefore, a certain amount of patience is needed to ensure your own planting benefits. That is all for today's introduction. This article is for reference only. Thank you for reading and supporting.
