Method for improving quality and yield of Aubade floribunda ryegrass seeds

Abstract

The invention discloses a method for improving the quality and yield of Aubade floribunda ryegrass seeds, and the method comprises the following steps of: (1) selection of a breeding base; (2) treatment of soil before sowing; (3) treatment of seeds before sowing; (4) sowing; and (5) weeding, fertilization, pest elimination after sowing. The step (2) comprises the following steps of: a, ploughing, harrowing, and turning over the soil; b, planning and designing the field; c, unselectively eliminating pests; and d, applying basal fertilizers: applying 300kg/hm<2> of basal fertilizer after the step c, wherein the basal fertilizer is a compound fertilize, in which the masses of N, P and K are respectively 15% of the total mass of the basal fertilizer. In the step (3), the seeds are treated for removing beards of the seeds; and in the step (4), a sower is used for sowing, and the row space is 40-60cm. The Aubade floribunda ryegrass planted through the invention can produce more than 60kg/mu of grass seeds each year, and the yield is obviously higher than that yield of Aubade floribunda ryegrass planted through the traditional planting method. The quality of the treated grass seeds can reach the quality standard of the grass seeds in the I-II national level.

Description

technical field [0001] The invention relates to a planting method of Lolium multiflora seeds, in particular to a method for improving the quality and yield of Lolium multiflora seeds. Background technique [0002] Aberdeen ryegrass belongs to the Gramineae family, and the ryegrass is a perennial (or annual) sparse bush-type herb that is native to the United States. Adaptability observations and variety comparison tests have been carried out in Hongyuan County in the alpine pastoral area of ​​Northwest Sichuan and the southern counties of the basin and hilly area. The grass species has wide adaptability, strong tillering ability, high grass yield, and good regeneration. , high quality and other characteristics, it was approved by the National Forage Variety Approval Committee in April 1988, and registered as an imported variety with the variety registration number 023. This variety is cultivated as annual pasture grass in the northwestern plateau of Sichuan, with an average ...

AI Technical Summary

Problems solved by technology

[0003] Although the grass seed has been popularized in a large area, no large-scale seed production base has been established so far. For a long time, farmers and herdsmen have relied on self-propagation and self-planting. , loose soil, fertilization, weed removal and other fine field management, the pasture growth is very poor, after mowing 1-2 stubbles of pasture and then used for harvesting, the harvested pasture seeds have low purity, low yield, many impurities, and small thousand-grain weight. Low germination rate, resulting in mixed varieties and degraded species

At present, there is no public literature on the planting method of Lolium multiflora seeds that can solve the above problems, and there is no application precedent
