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
The present invention relates to plant seed to produce, be specifically related to a kind of method improving Alfalfa Seed Yield.
Background technology
Alfalfa (Medicago sativa) is the high quality forage that cultivation history is the longest, cultivated area is maximum, value is the highest in the world, and its industrialization is day by day risen.More American-European countries are regarded as " green gold ", " fundamental to the building of the country ".China's alfalfa grassland industry is started late, but development rapidly, along with implementations such as National agricultural comprehensive exploitation, development of the West Regions, returning farmland to grassland, returning husbandry to grassland, under the support energetically and project-driving of governments at all levels, only statistics in 2011, China's Alfalfa Growing area has reached 133.3 ten thousand hectares, and with the speed increase of annual 100000 hectares, Gansu Province's Alfalfa Growing area in 2011 has reached 580,000 hectares, is the first in the nation.
In recent years, China's alfalfa seed is produced and is always lagged behind production development needs, and the whole nation is annual about produces alfalfa seed 4.2-5 ten thousand tons, also needs import alfalfa seed 50-500 ton, could meet country and send out returning farmland to grassland, returning husbandry to grassland and Developing Animal industry needs.
For a long time, China alfalfa seed is produced and is all belonged to spring sowing or autumn sowing, then stump, treats that Second Year clover in spring turns green, autumn seed bearing production process.Generally: during spring sowing, in ground, interplant cover crop, crop harvesting relief alfalfa growing to be protected, stump then, waters winter water and survives the winter; Cover crop is not planted in autumn sowing seed-breeding field, stump, waters winter water and survives the winter.After Second Year clover turns green, water, apply fertilizer, weeding, prevention and elimination of disease and pests, autumn gathers in after seed maturity, fortune threshing ground heap dry in the air, beat stone roller threshing, winnow, seed cleaning, preserves the production processes such as sale.The drawback of this production technology: one is need 2 years just to have seed harvest on implantation time, First Year peasant household does not have economic well-being of workers and staff completely in alfalfa seed is produced; Two is that seed production is low, general per mu yield more than ten to two ten kilogram.Existing production technology had both affected the enthusiasm for production at plantation family, was also unfavorable for the market demand of the fast development of China's alfalfa industry and the fast development of alfalfa seed industry.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art and deficiency, a kind of method improving Alfalfa Seed Yield is provided.The method can shorten the production cycle of alfalfa seed simultaneously, makes the biennial product cycle time of alfalfa seed be 1 year.
Object of the present invention is realized by subordinate's technical scheme:
Improve a method for Alfalfa Seed Yield, comprise the steps: meticulously to have executed base manure mid-March to the last ten-days period wholely, when soil moisture content is suitable, in mid or late March epiphragma bunch planting obducens alfalfa seed, after planting forbid in field planting all cover crops; The neat seedling of clover that mid-April is broadcast, late May clover enter squaring period, this mu spray casing coupling peace 3-4 gram phase; The flower bud phase is secondary to 7 to 12 days sprinklings boron fertilizer, potassium dihydrogen phosphate, molydbenum fertilizers to just spending, and mid or late June sees that the florescence waters a water; Open pesticide control thrips, the aphids such as prebloom spray imidacloprid wp, early July clover enter flowering stage (honey bees pollination will be introduced in the place that insect is few), early September to the middle ten days seed fruit pod 70 ~ 80% browning look results.
Described obducens alfalfa seed is preferably by the method preparation comprising following steps: in seed agitator, put into alfalfa seed, spray cmc soln while stirring and to continue stirring until alfalfa seed moistening, continue to stir after adding the rhizobium melioti accounting for alfalfa seed quality 1%, add cmc soln and Keep agitation to carrying disease germs evenly, then add C raw material to stirring and obtaining obducens alfalfa seed.Described C raw material by by occupying the biological humic acid of alfalfa seed quality 0.5%, the urea of 1%, potassium dihydrogen phosphate, the borax of 0.1%, indolebutyric acid, the methyl α-naphthyl acetate of 0.01%, the bentonite of 7% of 0.01% of 0.2% mix and obtain.
Preferably, the method for described raising Alfalfa Seed Yield, comprises the steps:
One, First Year seed produces:
