Method for promoting grassiness to overwinter in situ at Jiangsu coastal mud flat

Abstract

The invention discloses a method for promoting grassiness to overwinter in situ at the Jiangsu coastal mud flat. The method comprises the steps of after overground parts of the grassiness are cut in the area at the December of last winter, remaining the stubbles for 10-20cm; taking and crashing part of the leaves of the overground parts, doping the leaves with less soil mixed fertilizer and fully mixing with the soil of a cultivation field, and performing stack closing around the grassiness stubbles, slightly compacting, and sheathing a commercial available black plastic garbage bag, sealing with humid soil at the periphery of the bag edge, and slightly exposing the bag top; when the temperature is lower than 5 DEG C below zero, overlapping a black film and a certain number of grassiness bundles; and after the temperature rises to 13-17 DEG C at May of the next year, sectioning the bag top exposing out of the ground to promote the new sprout to germinate and grow, thus solving the problem of the grassiness overwintering in situ locally.

Description

Technical field [0001] The invention relates to a plant cultivation method, in particular to a method for promoting the overwintering of elephant grass in situ in coastal beaches of Jiangsu. Background technique [0002] Jiangsu Coastal Plain is located in the middle latitudes, and belongs to the transition zone from the northern subtropical climate to the southern warm temperate climate. Because it faces the Yellow Sea to the east, the ocean has a very obvious regulating effect, and it is also a humid monsoon climate zone. The main features of this area are: monsoon prevails, four distinct seasons, abundant rain, rain and heat in the same season, sufficient sunshine, and long frost-free period. For a long time, this area has been an important production base for forage grass. Elephant grass, namely Pennisetum purpureum, of the genus Pennisetum of the gramineous family, is a perennial herb in the south and is an important large-scale forage newly introduced locally. Elephant gr...

Problems solved by technology

For field cultivation, there has always been a problem that it is difficult to survive the winter naturally in this area

After harvesting in winter, it is often necessary to build greenhouse facilities and implement off-site seedling preservation. The cost of transplanting, transportation, and conservation is huge, thus limiting its further promotion in this area
