Embodiment Construction

[0018] The technical solution of the present invention will be further explained and illustrated through specific embodiments below in conjunction with the accompanying drawings.

[0019] The following will be illustrated with the embodiment of two different genotypes of wheat:

[0020] 1) Two different genotypes of wheat (respectively semi-winter variety: Yannong 19 and spring variety: Yangmai 18) were selected as the research objects, potted with soil in the field, the diameter of the pot was 30cm, the height was 30cm, and there were about 10 plants in each pot. Fill the field with 10kg of soil in each pot. Before sowing, apply 75g of organic fertilizer, 1.05g of pure nitrogen, 1.35g of P2O5, and 2.25g of K2O to each pot, and topdress each pot with 1.05g of pure nitrogen during the jointing stage of the wheat, and bury it in the test Tanaka, the management is the same as Datian.

[0021] 2) At the booting stage (early April), take the potted plants and place them in an arti...

Abstract

The invention discloses application of hormones to cold resistance and disaster mitigation of booting stage wheat. The hormones are preferably progesterone. During application, the progesterone at 0.05 mu mol/L by concentration is sprayed on leaves 24 hours after crops of the booting stage suffer from chilling damage. According to the application of the hormones to cold resistance and disaster mitigation of the booting stage wheat, by spraying the progesterone onto the crops of the booting stage which suffer from chilling damage, cold resistance of the booting stage wheat can be effectively improved, and influence of cold stress on growth and the yield of the wheat during the booting stage can be relieved.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to the application of sex hormones in cold resistance and disaster reduction at the booting stage of wheat. Background technique [0002] Wheat is an important food crop in my country and is of great significance to maintaining social stability and food security. In recent years, with the frequent occurrence of extreme climates, low temperature in spring has become an important limiting factor for global wheat production. Over the past few decades, low temperatures have caused significant reductions in wheat production in Australia, the United States, Europe and China. In the Yangtze River Basin of China, Anhui Province, Jiangsu Province, Henan Province and other wheat areas are prone to low temperature in spring, which has a great impact on wheat production. The low temperature in spring in the wheat region of the Yangtze River Basin mostly occurs from the end of March to the firs...
