1. The temperature of the temperature management facilities for cultivation at each growth stage should be consistent with the open field cultivation, especially at the flowering period to the fruit expansion period, the high temperature at noon and the low temperature at night often occur, and the temperature difference is relatively large, resulting in the impact on fruit growth, such as the appearance of abnormal fruit. Wait. For this reason, daytime ventilation and nighttime heat preservation are very important.
(1) The average temperature of the outside world in the peach-growing areas of China is approximately 5 to -5°C. Must pay attention to the insulation at night, to take double cover and other methods to ensure that the minimum temperature at night is not less than 5 °C, when the daylight is abundant, often more than 25 °C, but also must be timely ventilation to maintain the temperature of 25 °C.
(2) Pollination and fertilization of anthesis during flowering time requires a temperature of about 20°C, and poor fertilization if the temperature exceeds 28°C or lower than 10°C. At this time the weather is clear enough light, the daytime temperature within the facility can reach 30 °C or more, must pay attention to ventilation and ventilation to reduce the temperature, so that the daytime temperature does not exceed 25 °C, while the night heat preservation to not less than 10 °C is appropriate. The cultivation period of the peach planting period is long, and there is often a phenomenon of flowering and young fruit staggering. It is advisable that young fruit should have a temperature of no less than 15°C. Therefore, the nighttime insulation work is even more important.
(3) Fruit enlargement period Fruit enlargement is formed by cell division. Low temperature affects the cell division rate, while delayed ripening stage, rapid temperature cell division will cause fruit deformation. The suitable temperature for this period is 30°C during the day and 15°C during the night.
(4) The hard core phase At this time, the outside temperature has risen above 10°C, and the maximum temperature during the day can reach 30°C or more. It will often increase the consumption of nutrients due to the increase of respiration. Therefore, we must pay attention to the temperature control, so that the night to maintain about 10 °C, during the day does not exceed 30 °C.
(5) The fruits are about to mature at the rapid expansion of the fruit, and the cells expand rapidly. Due to the increase in outside temperature, daytime facilities often experience high temperatures above 30°C, and must be ventilated and ventilated in time to reduce the temperature and maintain the temperature at about 30°C.
(6) During the maturation period, the outside temperature rises, and it is difficult to maintain the temperature below 30°C during the day in the facility. It is necessary to remove the film or shading net to cool down the temperature according to the specific conditions.
(7) After the harvest, the membrane was completely removed and allowed to grow under natural conditions, and nutrients were produced and accumulated to promote flower bud differentiation. To lay the foundation for the flowering of the next year and the results.
