Description
Technical Field
The invention belongs to the technical field of seed harvesting methods, and particularly relates to a green manure seed collection method.
Background
Green manure (greenmanure) is a fertilizer made from green plants. Green manure is a biological fertilizer source with complete nutrients. The green manure is not only an effective method for increasing fertilizer sources, but also has great effect on improving soil. However, reasonable application is necessary to fully exert the yield increasing effect of the green manure.
Green manure can provide rich nutrients for soil. Tender stems and leaves of various green manure contain rich nutrients, and once decomposed in soil, the organic matters, nitrogen, phosphorus, potassium, calcium, magnesium and various microelements in the soil can be greatly increased. Every thousand kg of green manure fresh grass can generally supply 6.3 kg of nitrogen, 1.3 kg of phosphorus, 5 kg of potassium, which is equivalent to 13.7 kg of urea, 6 kg of calcium superphosphate and 10 kg of potassium sulfate. The green manure is mainly leguminous crops such as milk vetch, alfalfa, sweet clover, tamarix, sesbania, broad beans, amorpha fruticosa and the like; non-leguminous crops include rape, field radish, buckwheat, etc., and various aquatic green manure. After the green fertilizer crops grow for a certain period, the green stems and leaves of the green fertilizer crops are cut off and directly turned into the soil, so that the labor can be saved, the transportation cost can be reduced, and the retting soil fertilizer can be applied. The green manure contains various nutrients and a large amount of organic matters, can improve the soil structure, promote the soil curing and strengthen the soil fertility.
Because the reproductive capacity of green manure crops is very strong, the green manure crops can self-crowd, for example, the green manure crops such as the astragalus sinicus flowers in 2-6 months and the results in 3-7 months each year, the green manure crops such as the astragalus sinicus self-fall into the soil, young seedlings grow in 9 months, the green manure flowers in the second year, seeds are grown and the years are continued, therefore, the prior astragalus sinicus is generally not harvested after being planted and matured, although the astragalus sinicus can play the effect of green manure in the soil, the seeds of the astragalus sinicus cannot be recycled and sowed again, the value of the astragalus sinicus is not effectively utilized, and the seeds produced by the astragalus sinicus are too dense in the soil, so that the waste of the seeds is caused.
The application patent with publication number of CN112293054A discloses a portable grass seed harvesting device and a using method thereof, wherein a roller brush type threshing machine mainly aims at collecting grassy plants, seeds on the grassy plants can be swept down by driving a roller brush to rotate through a central shaft, and the damage to the seeds can be reduced to the greatest extent by proper rotation speed. The seed collecting bag can collect the seeds which are swept down from the roller brush thresher, the collecting cloth bag can be disassembled, and finally the seeds which fall down in the collecting bag are taken out from the collecting bag. The axial flow fan is mainly used for collecting the flocculent seeds of the grassland plants in the Compositae, and the flocculent seeds can be sucked into the seed collecting net bags through proper wind speed of the axial flow fan. The seed collecting net bag is detachable, so that the collected seeds of the asteraceae family can be conveniently taken out. This patent, although being convenient for collecting seeds of herbaceous plants, does not perform a sieving function of seeds and impurities, and thus, it is required to provide a seed collecting device having a sieving function.
