Embodiment 1

[0061] Example 1: Implementation of high-yield planting technology in alfalfa seed field

[0062] In Shangba Township, Suzhou District, Jiuquan, Gansu Province (98°30' east longitude, 39°37' north latitude, about 1480m above sea level), a high-yield experiment of alfalfa seed field colonization for 5 consecutive years (2002-2006) was carried out. 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 is 145.6 kcal / cm 2 . In the test area, light loam soil was selected i...

[0065] Example 2: Implementation of high-yield planting technology in alfalfa seed fields

[0066]From 2003 to 2007, according to the above-mentioned high-yield colonization of alfalfa seed field (planting of hole-sowing area) technology, high-yield colonization of alfalfa seed field in Linxi County, Chifeng City, Inner Mongolia (detailed steps are the same as in Example 1), according to the area of ​​0.24-0.26m 2 Controlled thinning per plant (cluster), the resulting seed yield, quality and thinning colonization in each year are compared with the local alfalfa seed conventional production technology (contrast), the results are shown in Table 2 below.

[0069] Example 3: Implementation of high-yield colonization technology in alfalfa seed fields

[0070] From 2004 to 2007, according to the above-mentioned high-yield colonization of alfalfa seed field (planting of hole-sowing area) technology, high-yield hole-planting of alfalfa seed field was carried out in Yangling, Shaanxi (detailed steps are the same as in Example 1), according to the area of ​​0.25-0.28m 2 Controlled thinning per plant (cluster), the resulting seed yield, quality and thinning colonization in each year are compared with the local alfalfa seed conventional production technology (contrast), the results are shown in Table 3 below.

Abstract

The invention relates to the agricultural field, which is a method for improving output and quality of lucern seeds, and comprises selecting and preprocessing land blocks, selecting grass seeds and breaking dormancy of lucern seeds, producing nodule bacteria into bacteria liquid, spraying the bacteria liquid to seeds in the dark, low-temperature and humid environment, and fully and evenly churning the nodule bacteria with the seeds, and planting and sowing, the occupied area of each seedling is 0.24-0.35m 2, adopting mild irrigating and fertilizing weedicide to weed, penetratingly irrigating for a time in the early stage of budding and flowering, and further watering in flowering and pod-bearing period, auxiliary pollinating by human labor and preventing and curing pests, when 2 / 3-3 / 4 of green pods of lucerns become brown and seeds become yellow, the seeds of lucerns are mature, and people can reap, and thinning out of branches and planting after seeds are reaped. The invention overcomes the shortcomings in the prior art and controls line space and planting distance to continuously achieve the highest seed output in many years.

Description

technical field [0001] The invention relates to the field of agriculture or animal husbandry, in particular to a method for improving the yield and quality of alfalfa seeds. Background technique [0002] Alfalfa (Medicago L.), Fabaceae, Papilionaceae, Medicago genus, widely distributed in Europe, Asia, America and Africa, there are more than 60 species in the world, 16 species in my country, widely distributed, wild and cultivated . Alfalfa is the earliest and most widely planted forage grass in the world. It has been cultivated for more than 2,000 years after it was introduced into my country via the "Silk Road". regions, even on the Qinghai-Tibet Plateau, the roof of the world. Alfalfa is known as the "King of Herb Grass". It not only has a high yield, but also has a good grass quality, and it is liked by all kinds of livestock and poultry. With the development of commodity economy, the scale of alfalfa industrialization has developed rapidly in recent years, and the plan...
