Embodiment 1

[0074] Example 1 Planting the "Gannong No. 3" alfalfa variety at Ciwoquan Base, Shangba Town, Jiuquan City

[0075] On March 28, 2012, this technology was applied to plant 16.3 mu of "Gannong No. 3" alfalfa variety in Ciwoquan Base, Shangba Town, Jiuquan City. The harvest was harvested on September 7 of that year, with a total yield of 451.5 kg of alfalfa seeds, with an average yield of 27.7 kg, irrigated with winter water in November of that year, and the greening ended on April 4, 2013 the following year, and harvested on August 18. The total yield of alfalfa seeds was 952 kg, with an average seed yield of 58.4 kg per mu.

Embodiment 2

[0076] Example 2 Cultivation of "Zhongmi No. 1" alfalfa variety in Ciwoquan Base, Shangba Town, Jiuquan City

[0077] On March 26, 2013, we continued to apply this technology to plant 22.7 mu of "Zhongmu No. 1" alfalfa variety at Ciwoquan Base, Shangba Town, Jiuquan City. It was harvested on September 12 of that year, with a total yield of 710.5 kg of alfalfa seeds, with an average seed yield per mu 31.3 kg. In the same year, "Zhonglu No. 1" was planted in Shengoutan Base, Nanhua Town, Gaotai County, Zhangye City, with an area of ​​13.5 mu. The sowing date was March 25, 2013, and the harvest date was September 8, 2013. The total production of alfalfa seeds was 431.5 kg, with an average yield of 32 kg per mu. The two experiments were watered with winter water in early November of that year. The seeds continued to be harvested in 2014. The seeds were harvested on August 17 and August 12 respectively. The total yield of alfalfa seeds in Ciwoquan was 1416.5 kg The total productio...

Abstract

The invention discloses a method for increasing the alfalfa seed yield. The method comprises the steps that soil is prepared and fertilizers are applied from the middle ten days to the last ten days of March and membrane covering, bunch planting and alfalfa seed pelleting are carried out in the middle and last ten days of March; the seedlings of alfalfa emerge in the middle ten days of April, alfalfa enters the squaring stage in the last ten days of May, and 3-4g of mepiquat chloride is sprayed per mu at the squaring stage; boron fertilizers, potassium dihydrogen phosphate and molybdenum fertilizers are sprayed every other ten days from the bud stage to initial flowering, and watering is carried out once at every flowering stage in the middle and last ten days of June; pesticides are sprayed before flowering to control thrips and aphids and alfalfa enters the flowering stage in the first ten days of July; the seeds are harvested when 70-80% of seed pods become brown in the first ten days to the middle ten days of September. The method has the beneficial effects that the used coated seeds are inoculated with rhizobia, so that the application amount of nitrogen fertilizers is reduced, and environmental pollution of the nitrogen fertilizers is alleviated; the production cycle of the alfalfa seeds is shortened from two years to one year, namely, one season of seeds are additionally produced, so that the occupation ratio of the land on which alfalfa is planted in the current year can be reduced, the use ratio of the land is increased, and the seed yield and the incomes of growers are increased.

Description

technical field [0001] The invention relates to plant seed production, in particular to a method for increasing the yield of alfalfa seeds. Background technique [0002] Alfalfa (Medicago sativa) is a high-quality forage grass with the longest cultivation history, the largest planting area and the highest utilization value in the world, and its industrialization is rising day by day. Some countries in Europe and the United States regard it as "green gold" and "the foundation of a country". my country's alfalfa industry started relatively late, but it has developed rapidly. With the implementation of strategies such as national comprehensive agricultural development, western development, returning farmland to grass, and returning pasture to grass, under the strong support of governments at all levels and driven by projects, only According to statistics in 2011, the planting area of ​​alfalfa in my country has reached 1.333 million hectares, and it is increasing at a rate of 1...
