Frost prevention method for wild pepper and special aerosol

Abstract

The invention provides a frost prevention method for wild pepper and a special aerosol so as to meet the frost prevention need in production of the wild pepper and further improve yield. The frost prevention method for the wild pepper comprises the steps of applying the aerosol in a field before frost approaches for frost prevention during the growth period of the wild pepper and simultaneously spraying an anti-freezing agent during the bud swelling period. The special aerosol is characterized by being prepared from the following components: 10 plus or minus 2% of waste diesel oil, 50 plus or minus 10% of sawdust, 30 plus or minus 5% of nitramine and 10 plus or 2% of fine coal powder. The frost prevention method disclosed by the invention combines plant physiological research with research and development of the aerosol and the anti-freezing agent against the early spring freezing damage problem of the wild pepper, researches a frost observation and prediction technology by taking critical frost temperature of the wild pepper as reference, researches and develops the aerosol by taking long smoking time, good temperature-increasing effect and convenience in use as targets, develops an anti-freezing medicament for the wild pepper by taking a plant inhibitor and hormonal substances as materials, seeks for a frost prevention technology matched with the wild pepper by taking the frost prediction and the comprehensive application of the aerosol and the anti-freezing agent as a starting point and further has important significance for promoting great development of the wild pepper industry in China and upgrading a high yield technology.

Description

technical field [0001] The invention belongs to the technical field of agricultural crops, in particular to the frost protection technology in the pepper crop process. Background technique [0002] Fengxian County, Shaanxi Province is located in the hinterland of the Qinling Mountains, on the dividing line between the subtropical zone and the temperate zone. Its rich land resources, warm climate type, excellent Zanthoxylum bungeanum germplasm and clean production environment have created necessary conditions for the production of high-quality Fengxian Dahongpao. Dahongpao Zanthoxylum bungeanum (Fengjiao) produced in Fengxian County is unique because of its well-developed oil glands, rich and long-lasting numb taste, delicate smell, and bright color. It has been famous all over the country and abroad as early as the Ming and Qing Dynasties. In 2004, Fengjiao successively obtained national qualifications such as "Protection of Regional Origin Products", "Organic Food Certific...

Problems solved by technology

However, there are no "antifreeze" products that have obvious effects and are specially used for peppercorns; although there have been reports on the development of aerosols before, most of them are due to short fuming time, poor warming effect, inconvenient use, It is difficult to popularize in production due to poor antifreeze effect and other reasons
