Abstract

The invention discloses a cold-resistant agent for growth of Chinese trichosanthes. The cold-resistant agent comprises the following components by weight: 5-7.5mg of abscisic acid, 0.03-0.06g of salicylic acid, 0.6-1g of calcium nitrate, 0.035-0.04g of putrescine, 0.05g of spermidine, 0.45g of urea, 0.3g of monopotassium phosphate, 0.04g of citric acid, 0.1g of malic acid, 0.05g of chitosan, and 1L of water. The invention simultaneously discloses a using method of the cold-resistant agent for growth of Chinese trichosanthes. The method comprises the following steps of: spraying leaves of a Chinese trichosanthes plant by a Chinese trichosanthes cold-resistant agent until the leaves drip 12-48 hours before a cold wave comes. By adopting the cold-resistant agent for growth of the Chinese trichosanthes disclosed by the invention, the ability of the Chinese trichosanthes for resisting low-temperature damage can be obviously enhanced; and the stability of a Chinese trichosanthes cell membrane also can be enhanced.

Description

technical field [0001] The invention relates to a cold-resistant spraying agent, in particular to a cold-resistant agent capable of improving the cold-resistant ability of Trichosanthes chinensis. Background technique [0002] Chilling damage is a kind of agricultural meteorological disaster. Chilling injury hinders the physiological activities of crops, and in severe cases, some tissues are destroyed. With the deterioration of the ecological environment, global climate anomalies have become a huge hidden danger of crop yield reduction, forest area reduction, and extinction of endangered animals and plants. In recent years, the La Niña climate has entered China, and the resulting abnormal cooling and precipitation have caused huge economic losses. At the beginning of 2008, due to the impact of the "La Nina" climate phenomenon, the temperature in some provinces and cities in my country dropped sharply. The loss of many crops due to low temperature and cold damage is as hig...
