How to manage chestnut trees

Chinese chestnut is a kind of common nut in daily life, and it also has a wide planting area in our country, even in the south. Now the demand for Chinese chestnut is increasing, and the planting area of our country is gradually expanding. The planting of Chinese chestnut is not as simple as we think. Because the chestnut needs to do a good job of management after planting in order to ensure the normal growth of chestnut, the following editor brought the management method of chestnut tree, let's have a look!

1. Loosen the soil and expand the hole

The soil should be loosened in the autumn after planting, and the depth of the soil should not be less than 30 cm. When loosening the soil, it is necessary to observe the root distribution of chestnut trees, and the trees with more shallow distribution should be shallower. On the contrary, it can be ploughed deeply, pick out the stones when loosening the soil, and then apply the base fertilizer. Then in the planting about 3 years after the appropriate expansion of the hole, on the basis of the original planting point, at least to expand around 50 cm. When expanding the hole, we should pay attention to separate the topsoil, pick up the stones inside, and then mix the fertilizer with the topsoil and backfill, which is slightly higher than the ground after backfilling. When expanding the hole, it is necessary to prevent the root of Chinese chestnut from being injured and affect the absorption of nutrients.

2. Ploughing and weeding

Intertillage weeding is very important to the growth and development of Chinese chestnut, because in the young stage of Chinese chestnut, the root capacity is not developed enough, the nutrient absorption is weak, and is threatened by weeds. Therefore, intertillage weeding should be carried out at least twice a year in the growth of chestnut trees. Intertillage can not only effectively control weeds, but also improve soil permeability and soil moisture conservation. Promote root respiration and nutrient absorption, be careful not to hurt the roots when weeding, and pay attention to the amount of herbicides when using herbicides to prevent effects on chestnut trees. Weeded grass can be turned into the soil as green manure.

3. Reasonable intercropping

The distance between chestnut trees is relatively large, so we can reasonably interplant between chestnut trees. Intercropping crops should choose crops with low stem, short growth period and low demand for fertilizer and water, and ensure that they can improve soil fertility and improve soil structure without common diseases and insect pests with Chinese chestnut. Such as peanuts, peas and so on. After planting Chinese chestnut for 2-3 years, the intercropping crop density should be reasonably controlled. And with the growth of chestnut trees, the expansion of tree shape, slowly increase the planting density of intercropping crops, until the end of intercropping. Mature crops can be turned directly into the field, as green manure, large-scale can also be harvested and listed on the market.

4. Water and fertilizer management

Chinese chestnut has strong adaptability, but wants to achieve the goal of high yield. It is still necessary to ensure adequate nutrition. In many places, the soil is relatively barren and there are few nutrients. As a result, it can not bear fruit for several years, and it also reduces people's enthusiasm for planting Chinese chestnut. Therefore, when planting, we should not only choose fertile soil, but also do a good job of topdressing, the number of times of topdressing in the planting process should not be less than twice a year. And the nutrition in the fertilizer should be distributed reasonably to ensure that the nutrition is adequate and comprehensive. The soil should be watered in time when the soil is too dry, but small water drip irrigation should be given priority to, water should not be excessive, and drainage should be paid attention to when there is too much water or rainy days.

The above is a brief introduction to the management methods of chestnut. The growth period of Chinese chestnut is relatively long, but there are many times of fruit, and one planting can be harvested continuously for many years. It is a kind of crop with high economic value, but in the growing period of Chinese chestnut, we need to do a good job of management to ensure the healthy growth of Chinese chestnut. Therefore, you need to have a certain degree of patience in order to ensure their own planting efficiency. That's all for today's introduction. This article is for reference only.
