Method for mowing Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo stage by stage and cultivating and utilizing harvested seeds

Abstract

A method for mowing Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo stage by stage and cultivating and utilizing harvested seeds includes the steps that area selection is performed; seedlings are grown; cultivation and utilization are performed in the current planting year; Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo is mown stage by stage and harvested seeds are cultivated and utilized since the second year; according to the stage-by-stage mowing of Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo and cultivation and utilization of the harvested seeds, since the second planting year, the Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo is mown once in July or August every year as forage grass, seeds are harvested from January to February every year since the third planting year, from the time when pods appear to the time before harvesting of the seeds, watering is performed once every 14 days to 16 days, and from the time after harvesting of the seeds to the time when the dry season is over, watering is performed once a month. With the method, the benefits of unit area of cultivation field are effectively increased, and the benefits of the unit area are increased by 566.45% annually compared with the situation that Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo is merely used as forage grass, two agricultural products including forage grass and seeds can be obtained in one growth cycle, and meanwhile soil fertility is improved.

Description

technical field [0001] The invention relates to the technical field of planting forestry crops, in particular to a method for segmental cutting, seed collection and utilization of Tinaro sylvatica plants. Background technique [0002] Neonotonia Wightii (Wight&Arn.) Lackeycv.Tinaroo] originated in Africa and is an excellent legume forage in tropical and subtropical regions because of its high forage yield, good palatability and high seed yield. Introduced from Kenya to various places, my country introduced it from Australia in 1983. Years of practice have shown that Tinara New Lotonbean likes tropical climates, is resistant to barren and alkaline, acidic, and lean soils, and is suitable for pH values ​​of 5.27-8.90, organic matter content of 5.1-6.9g / kg, and total phosphorus of 0.15-0.27g / kg , soils with low nutrient storage. This pasture has strong adaptability and can grow well in tropical and subtropical regions with annual precipitation above 600 mm. Flowering begins i...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the existing method of utilization of Tinara sylvadon bean pasture, which only mows the pasture as forage grass or harvests it as seed every year, resulting in low economic benefits. , and there is no scientific and reasonable cultivation and management technology before and after the forage grass is mowed or seed harvested, resulting in the low yield of the pasture grass whether it is used as forage grass or as seed, and the defects that the plants are easy to die
