What kind of environment is suitable for processing small package chestnut?

Chestnut is a kind of tree species that can adapt to a variety of climate and soil conditions. However, under different climate and soil conditions, their growth and development, fruit richness, variety quality and so on are different, even very different. What kind of environment is suitable for processing chestnuts in small packages?

1. Temperature

The average temperature suitable for chestnut growth is 8-15 ° C. Chestnut trees in the north are relatively cold resistant and can withstand a low temperature of -25 ° C. This is basically consistent with the isotherm, and the annual average temperature is 8-10 ° C. The cold tolerance of chestnut tree is related to its variety and age. The younger the tree age, the worse the cold resistance. Under the climatic conditions of Kuancheng County, a large number of annual chestnut seedlings freeze to death due to low temperature in winter. Taking cold proof measures for trees is the key to ensure the safety of the garden. The annual average temperature is 5.5-7 ° C, and the temperature is basically below -35 ° C. Chestnut trees can still grow and bear fruit, but their vitality is poor. The temperature is insufficient in the mature period, the fruit is small, the yield is low, the quality is poor, and there is peeling in winter. Therefore, the altitude of our county is high, and the hillsides and gullies in the shady area are not suitable for planting chestnuts.

2. Rainfall

Chestnuts can adapt to rainy and humid climate. The total rainfall is between 600-700 mm. The soil humidity should be 30-40%. Excessive drought will lead to tree development and yield decline, especially in the rapid growth stage such as insufficient water supply, which will adversely affect the growth and fruit of chestnuts. The names of chestnut producing areas are "chestnut dried jujube" and "persimmon jade pear", indicating that heavy rainfall can bring a good harvest. However, chestnuts are not resistant to waterlogging. This is usually caused by poor soil drainage and long-term root flooding, resulting in leaf abscission and even the death of the whole plant. Appropriate rainfall before autumn ripening can promote fruit growth and increase yield. If there is too much rain in autumn, the fruit will also crack, affecting the yield and quality.

3. Lighting

Chestnut is a light loving tree species, avoiding shade. In the valley where the light is less than 6 hours a day, the tree crown grows upright, the leaves are thin, the branches are thin, and the yield is low. In the flowering and fruiting period, insufficient light will lead to physiological fruit drop. If it is shaded excessively for a long time, the inner branches and leaves will turn yellow, thin and weak, and even wither. Therefore, it is recommended to plant chestnut trees on sunny slopes or open valleys. In order to enhance the light, the main branches of the crown should be mainly sparse, so as to facilitate the results of the inner hole.

4. Terrain

Chestnuts are mainly distributed in mountainous areas and slopes, and the requirements for slopes are not too strict. The labor intensity of chestnut management is lower than that of fruit management, which is conducive to soil and water conservation. Slopes up to 45 degrees can be used. Because the downhill soil is very thick and there are alluvial fans in the valleys, chestnut trees in mountainous areas usually choose downhill alluvial fans or valleys. Chestnut trees should be planted on slopes. Although the downhill soil layer is very thick, it is easy to accumulate water and should be drained. Although the uphill soil layer is very thin, the deep soil is mixed with gravelly soil. The roots of chestnut trees can extend to the soil layer along the rock gap, and chestnut trees can grow normally. If you can change the thin soil layer, that is, dig a big hole before planting, expand the soil capacity during the growth of chestnut orchards, or strengthen soil improvement and management, the effect will be very good.

5. Soil

Chestnut trees are suitable for planting on acidic or slightly acidic soil. They grow well in soil with pH value of 5-6, but poor when pH value is higher than 7.2. Therefore, when developing chestnut trees, we should pay attention to the selection of soil. Even the owner of granite soil suitable for chestnut growth, if the soil layer is shallow and the soil quality is poor, it is necessary to strengthen soil management and increase fertilization and water to ensure yield increase.

The above is what kind of environment is suitable for processing small packaged chestnuts.
