高寒冷凉区设施葡萄果实肉囊成因研究

Study on Causes of Grape Fruit Chamber in Greenhouse of High Cold Area

本试验研究了不同昼夜温差、氮肥施用量、赤霉酸处理次数和灌溉量的葡萄肉囊大小和发生率。结果表明:昼夜温差、氮肥施用量、赤霉素处理次数和灌溉量与肉囊的大小和发生率正相关。降低昼夜温差、氮肥施用量、赤霉素处理次数和灌溉量有利于降低肉囊大小和发生率。

This experiment has studied size and rate of grape fruit chamber about different temperature between day and night, consumption of nitrogen, treating times of GA, and rate of irrigation. The result showed that size and rate of grape fruit chamber are positive correlations with temperature difference between day and night, consumption of nitrogen, treating times of GA, and rate of irrigation. Decreasing temperature difference between day and night, consumption of nitrogen, treating times of GA, and rate of irrigation can decrease size and rate of grape fruit chamber.
