Chestnuts are generally adaptable to climate and soil conditions. The suitable annual average temperature is 10.5-21.7 ℃. If the temperature is too high and there is no hibernation, it will lead to poor growth and development. If the temperature is too low, chestnut is easy to suffer from freezing injury. Tiancheng chestnut not only likes wet soil, but also fears the influence of rain. Therefore, chestnut orchards should not be developed in low-lying and flood prone areas.
Chestnut is more sensitive to soil pH and is suitable for growing on slightly acidic soil with pH value of 5-6. This is because chestnut is a high manganese plant. Under acidic conditions, they can activate nutrients such as manganese and calcium, which is conducive to the absorption of chestnuts. And applications.
The opening process of male flowers in chestnut can be roughly divided into four stages: filament exposure, filament straightening, filament cracking and filament withering. The whole flowering process takes about 10 ~ 15 days. In a male inflorescence, the male flowers at the base always open first and gradually extend upward, with a difference of about 15-20 days. The flowering period of the spikelets with female flowers is about 5-7 days later than that of the single male flowers.
The female flower has no petals, and the opening process of the female flower is mainly regulated by the growth and development of the stigma. The flowering process can be divided into five stages: female flower presentation, stigma presentation, stigma bifurcation, stigma expansion and stigma inversion.
From the bifurcation of the stigma to the expansion, the stigma insisted on being novel, and the villi on the stigma secreted mucus for about half a month, which was the main period of pollination. At this time, high temperature and sufficient light were conducive to the pollination and fertilization of chestnut, which on the contrary affected the yield of chestnut.
