Embodiment 1

[0036] In April 2008, the foliar spray test was carried out in the wheat (Changwu 135) experimental field of Changwu Agricultural Ecological Experimental Station, Wangdong Village, Hongjia Township, Changwu County, Shaanxi Province. The average annual rainfall in this area is 540mm, which is a typical semi-humid Loess Plateau. In drought-prone climate areas, during the jointing growth period of wheat, the concentration of 0.05mmol L in the evening -1 SNP and 0.008mmol·L -1 6-BA formulation solution 0.5m 3 Spraying per mu, the same amount of tap water is used as a contrast treatment, and it is sprayed onto the wheat leaf surface until dripping, and each treatment is repeated 4 times. Three days after spraying, the changes of growth index leaf area index, plant height, stem base thickness and root activity were measured. The wheat leaf area index, plant height, stem base thickness and root activity of the plant growth regulator of the present invention are respectively increas...

Embodiment 2

[0038] In March, 2008, the plant growth regulator of the present invention was added to the wheat (Xiaoyan 22) experimental field in Wuquan Township, Yangling District, Shaanxi Province when the micro-sprinkler irrigation facility was used to irrigate water, and the spraying test was carried out. The annual average rainfall in this area is 650mm, which belongs to semi-humid climate Area. During the jointing growth stage of wheat, the concentration of 0.1mmol L -1 SNP and 0.01mmol·L -1 6-BA formula solution 3m 3 / mu was applied to the wheat rhizosphere, and the same amount of tap water was used as a contrast treatment, and each treatment was repeated 3 times. Three days after drip irrigation, samples were taken to determine growth indicators such as leaf area index, plant height, stem base thickness and root activity. The above growth indexes of wheat sprayed with SNP and 6-BA formula solution were increased by 13.1%, 12.3%, 16.5% and 26.0% respectively compared with the con...

Embodiment 3

[0040] In April 2008, the foliar spray test was carried out in the wheat (Changwu 135) experimental field of Changwu Agricultural Ecological Experimental Station, Wangdong Village, Hongjia Township, Changwu County, Shaanxi Province. The average annual rainfall in this area is 540mm, which is a typical semi-humid Loess Plateau. Drought-prone climate areas, in the jointing growth stage of wheat, the concentration of 0.15mmol L -1 SNP and 0.04mmol·L -1 6-BA formulation solution 0.5m 3 / mu was applied to the wheat field, and the same amount of tap water was used as the control treatment, and each treatment was repeated 3 times. Three days after drip irrigation, samples were taken to determine wheat growth indicators such as leaf area index, plant height, stem base thickness and root activity. The above growth indexes of wheat sprayed with SNP and 6-BA formula solution were increased by 4.0%, 7.5%, 13.3% and 11.9% respectively compared with the control.

Abstract

The present invention discloses a plant growth regulator for improving the growth characteristics of dry land wheat in the jointing stage, which contains 83 to 93 percent of sodium nitroprusside SNP and 17 to 7 percent of cytokinin 6-BA by weight percentage. The regulator can be quickly absorbed by roots or leaves, thus improving the physiological and ecological drought resistance of dry land wheat and laying a solid foundation for stable and high wheat output. In addition, the regulator also has the advantages of low use cost, less dosage, no residue, no environment pollution, simple use and easy access to wide promotion.

Description

technical field [0001] The invention relates to a plant growth regulator for improving the growth characteristics of dryland wheat at the jointing stage. Background technique [0002] my country's arid and semi-arid areas account for more than half of the country's land area, and the arable land in the arid area is about 5057×10 4 hm 2 , accounting for about 51% of the country's total arable land. The dry agricultural area has a vast territory, diverse climate and rich resources, and is an important grain-producing area in my country. However, the agricultural production in this area has always been dominated by rain-fed, and the lack of water resources is the main environmental factor restricting the development of dry farming. Therefore, it is of great significance to improve the agricultural productivity of dryland crops to regulate the physiological characteristics of dryland crops through various cultivation techniques. [0003] When water is deficient, the water ab...
