Planting conditions of Chinese chestnut

Climatic conditions: the annual average temperature should be between 10 ℃ and 22 ℃. Soil conditions: slightly acidic soil is needed, and the soil should be moist and waterlogged. Planting site requirements: it is necessary to choose places with low groundwater level and good soil drainage. Variety requirements: good local varieties should be selected, and early varieties, medium varieties and late varieties should be matched reasonably. Planting density requirements: general plain chestnut orchard planting 30-40 plants per mu, mountain chestnut orchard planting 40-60 plants per mu.

I. specific requirements for climatic conditions in chestnut planting

1. Chinese chestnut is suitable to be planted at an annual average temperature of 10.5 ℃ to 21.8℃. If the temperature is too high and the hibernation of Chinese chestnut is insufficient, it will lead to poor production and development. If the temperature is too low, Chinese chestnut will freeze and limit its growth and development.

2. Chinese chestnut has certain requirements for soil moisture, which should be moist and waterlogging. if there is more rainfall, the soil will produce stagnant water, which will affect the root of Chinese chestnut, especially on the growth of root fungi.

3. Chinese chestnut is also sensitive to the acidity of soil, and the slightly acidic soil is suitable for the growth of Chinese chestnut.

Therefore, it is not suitable to grow Chinese chestnut in waterlogged or low-lying areas.

Second, the choice of garden land

The planting land of Castanea mollissima should be chosen as far as possible where the groundwater level is relatively low and the soil has better drainage. You must not choose alkaline soil, windy or waterlogged places. When planting Chinese chestnut in hilly land, we should choose the place where the soil layer is thick and gentle, close to the mountain, and then slowly develop to the place where the planting is slightly worse.

III. Variety selection

Excellent local varieties should be selected as far as possible, and the reasonable coordination of early, medium and late varieties should be made, and excellent and suitable varieties should be selected according to different edible requirements.

IV. Reasonable close planting

The planting density of Castanea mollissima is generally 30 ~ 40 plants / mu in plain chestnut orchard and 40 ~ 60 plants / mu in mountainous chestnut orchard. 60 ~ 111 plants / mu can be planted in dense planting, and interrow, interplant and thinning treatments are carried out gradually in the later stage. reasonable close planting can increase the yield of Chinese chestnut.
