Seed blower helps improve seed quality Also known as cocksfoot, orchard grass, Dactylis is a perennial herb of the genus Drosophila. The suitable area for the production of D. esculenta seeds is the mid-subtropical region with an annual rainfall of 800-1 300 mm and an altitude of 1200-1600 m. Temperatures in areas with lower elevations are higher, and flowering and seeding periods are earlier. At the time of the rainy season in the south, pollination is insufficient, the seed setting rate is low, the seeds are prone to mildew and deterioration, and the yield is reduced. The seed quality is also poor. If the flowering and fruiting period is postponed to August, we can miss the rainy weather and increase seed production. However, in high altitude areas, Dactylis glomerata has a long growth period, a long flowering period, and is not easy to manage. Drosophila seed sowing: Dactylis is a cool-season grass species, generally sowing in the autumn, with 8 to 10 months is appropriate, the early sowing climate is hot, not conducive to seedling growth, and vulnerable to weeds, too late sowing, Due to the lack of rainfall, lack of moisture, and susceptible to the influence of low temperature in the later period, it is not conducive to the growth of seedlings. Normal seeds (purity of more than 98%, germination rate of more than 90%) generally sowing amount between 15 ~ 22.5kg/hm2. Seed sowing, spacing is about 40cm. When artificial sowing, first open the groove according to the specified spacing, the depth of the ditch is 3~5cm, spread the seeds evenly into the ditch, then cover the soil, and cover the soil depth 2~3cm. Covering the soil can reduce the bird seedlings and rats feeding on seedlings to cause seedling deficiency and increase seedling drought resistance. Mechanical sowing is performed simultaneously with the ditching and sowing. Drosophila seed cleaning: The threshed seeds are mixed with straw, spikelets, pods, etc., and dried seeds need to be cleared for storage and seed quality evaluation. The seed blower is used for the analysis of the seed clarity of Dactylis glomerata, and the seed is distinguished mainly by using different seeds and different floating speeds of seeds and impurities. Dactylis seeds are small and the grain weight is small. With the rainy conditions in the south, some seeds can germinate and become seedlings, but they are not full. Therefore, the difference between the weight of good seeds and pods is small, and it is difficult to clear them with general wind selection. The only way to separate good seeds from pods and debris is to use a seed cleaner. When the average seed amount is not large, it can be cleared by a small seed cleaning machine. When the seed amount is large, it is processed by a large-scale joint cleaner.
