The latest management methods and technical key points for chestnut trees

Chestnut is a relatively common nut in daily life, and it also has a wide planting area in China, even with large areas of wild stands 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. That is because after planting chestnuts, management work must be done well to ensure normal growth. Below, the editor brings you the management methods for chestnut trees. Let's take a look!

1. Loosening the soil and expanding the planting hole

In the autumn of the same year after planting, soil loosening should be carried out, and the depth of loosening must not be less than 30 cm. When loosening the soil, observe the distribution of the chestnut tree's root system. Trees with shallow and numerous roots should be loosened a little more shallowly. Conversely, deep loosening can be used. When loosening the soil, pick out the stones, then apply base fertilizer. Then, about 3 years after planting, appropriately expand the hole. On the basis of the original planting hole, expand at least another 50 cm in all directions. When expanding the hole, 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 hole, prevent injury to the chestnut roots, 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 well developed, 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 control 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 effects on the 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 the chestnut trees. The intercrop crops should be low-stalk, short-growing-period crops with low fertilizer and water requirements, and it should be ensured that they can improve soil fertility, improve soil structure, and do not share pests or diseases with chestnuts. For example, peanuts, peas, and so on. After 2-3 years of chestnut planting, reasonably control the density of intercrop crops. And as the chestnut trees grow and the tree form expands, gradually 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 relatively large, they can also be harvested and sold on the market.

4. Water and fertilizer management

Chestnuts have strong adaptability, but to achieve the goal of high yield, it is still necessary to ensure sufficient nutrients. In many places, the soil is relatively barren and low in nutrients. This causes no fruiting for several years after planting and also reduces people's enthusiasm for growing 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 twice. 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 drip irrigation should be the main method. The amount of water should not be excessive. When there is too much standing water or in rainy weather, 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 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.
