Problems solved by technology

[0004] The research on the production of wheatgrass seeds includes: the research on seed yield and yield components with water, nitrogen or phosphorus fertilizer; The main factor of seed yield, blue stem icegrass is extremely sensitive to water and nitrogen, and its seed field irrigation and nitrogen application can easily cause large areas of plant lodging, resulting in a large reduction in yield and seed quality. This technical problem has always been troubled by blue stem ice The bottleneck of grass seed yield and quality has not been solved so far
However, there are few studies on its application in forage seed production

Embodiment 1

[0055] Example 1: Field experiment in Shangba Township, Suzhou District, Jiuquan, Gansu

[0056] In Shangba Township, Suzhou District, Jiuquan, Gansu Province (98 ° 30' east longitude, 39 ° 37' north latitude, about 1480m above sea level), according to the production method of the present invention, the production method of the present invention has been carried out for four consecutive years (2002~2005). Seed test. The annual average temperature of this place is 7.3°C, the average temperature of the coldest month (January) and the hottest month are -15.6°C and 28.7°C, and the extreme minimum and maximum temperatures are -31.6°C and 38.4°C. The annual rainfall is 85.3mm, the rainfall is mainly concentrated in June-August, and the evaporation is 2148mm. The annual sunshine hours are 3033h, the average frost-free period (1958-1980) is 130 days, the 80% guaranteed rate frost-free period is 119 days, and the accumulated temperature ≥10℃ is 2954℃. The total annual solar radiation...

Embodiment 2

[0063] Example 2: High-yield experiment in the seed field of Agropyron aeruginosa in Yangling, Shaanxi

[0064] From 2004 to 2007, according to the production method of wheatgrass seeds of the present invention, the forage test area of ​​the Department of Grass Science of Northwest Agriculture and Forestry University of Science and Technology in Yangling, Shaanxi was continuously tested for 4 years, and the technology of the present invention was implemented in 2005 to 2007 (detailed steps are the same as the implementation) Example 1), every year in the late stage of rejuvenation to the early stage of jointing, the plant growth regulator PP333 is sprayed 3 times in total, and the concentration of each spray is 1.7kg / hm of active ingredient 2 , the seed yield in each year of gained, quality are compared with local Agropyresis seed conventional production technology (the contrast that does not use plant growth regulator PP333), the result is as follows table 3

Abstract

The invention discloses a method for producing western wheatgrass seeds. In the method, 0.9-2.1kg / hm<2> of effective components of a plant growth regulator PP333 is sprayed on leaf surface of the western wheatgrass for 2-3 times every 5-7 days from late stage in turning green to the prophase of jointing of the western wheatgrass, thus greatly reducing plant height, effectively avoiding plant lodging and substantially improving the output and quality of the seed, which ensures that extensive application of the western wheatgrass in excellent pasture variety in revegetation and ecological conservation of deteriorated grassland, grassland agriculture and production practice of pasture grass seeds. The method has simple production method, low cost and simple operation, can substantially improve the output of the western wheatgrass seeds and the seed quality to some extent, and have good popularization and application prospect.

Description

technical field [0001] The invention belongs to the field of agriculture and animal husbandry, and relates to the production of grass seeds, in particular to a production method of Agropyron aeruginosa seeds, which can greatly improve the yield and quality of Agropyron aeruginosa seeds. Background technique [0002] Bluestem wheatgrass (Pascopyrum smithii (Rydb) A. Love) is an excellent grass species for supplementing natural pastures and establishing artificial grasslands. It is a long-lived perennial grass forage suitable for growth in cold, semi-humid, semi-arid and transitional regions. Due to its well-developed rhizome, drought resistance, cold resistance and adaptability to soil and climate, it can be used as sowing in arid areas, rebuilding grassland vegetation or effectively controlling soil erosion on roadsides and waterways; High growth vigor, abundant leaves, and high yield of forage grass are of great significance for improving natural pastures, solving forage gr...
