Method for keeping freshness of tropic pennisetum in temperate regions in winter

Abstract

The invention discloses a method for keeping freshness of tropic pennisetum in temperate regions in winter. The method for keeping the freshness of the tropic pennisetum in the temperate regions in winter is for the pennisetum to be harvested in autumn; and by spraying a mixed solution of abscisic acid and monopotassium phosphate to the pennisetum in a growing period, stems are appropriately dehydrated and enter a sleep state in advance. After the pennisetum is cut, methanoic acid is sprayed to the pennisetum to disinfect the pennisetum; and after the disinfected pennisetum is bundled, the pennisetum is put into a pit and can be safely stored for 7 months. Compared with an existing pit digging preservation method, the method for keeping the freshness of the tropic pennisetum in the temperate regions in winter, disclosed by the invention, has the advantages that 1, the pennisetum which is 10-12 days before stopping growing is selected; the advantages are that the in-year effect of the pennisetum is not affected, and the storage time in winter can also be shortened; 2, the mixed solution of abscisic acid and monopotassium phosphate is sprayed to the field before the pennisetum is harvested so as to create a condition for advanced dormancy and safety wintering of the pennisetum; 3, the methanoic acid solution is uniformly sprayed to the pennisetum to guarantee that the pennisetumis not prone to being deteriorated; and 4, wet clay covers a plastic film to be beneficial for buffering low temperature in winters and prevent freeze injuries.

Description

technical field [0001] The invention relates to a method for storing tropical pennisetum fresh in winter in temperate regions, and belongs to the technical field of planting. Background technique [0002] Forage is the key to the development of animal husbandry. Without high-quality forage, modern animal husbandry cannot be guaranteed. my country is the country with the largest number of herbivores in the world, which requires enough land to grow forage grass. However, my country is a country with limited arable land, which leads to limited land for planting high-quality forage materials. Livestock and poultry breeding Insufficient forage resources. This just requires planting high-yield, high-quality high-quality forage grass as much as possible on a limited land. So far, pennisetum from the tropics is recognized as the forage grass with the highest yield and good nutritional quality, so expanding its planting range is of great significance to solve the shortage of forage ...

AI Technical Summary

Problems solved by technology

However, the problem in production is that the grass cannot survive the winter in the temperate zone. The methods currently used in production are pit digging and cellar preservation. Less than 30%, so the stems must be purchased from the south every year, and the cost is also high, which affects the promotion and application of this grass
