Problems solved by technology

However, there are currently no effective prevention and control measures for late frost damage in tea gardens.
Smog anti-frost has been approved in my country's agriculture and Japanese agriculture, but at present most of the agricultural producers use the method of burning straw on the open space in the field before the freezing damage to prevent freezing, but there are potential safety hazards in this method on the one hand, and on the other hand On the one hand, it will cause air pollution, and there is no way to control the whereabouts of the smoke, and the antifreeze effect is poor
At present, smoke generators are also used in agriculture, but they are mainly used in greenhouses for pest control, and smoke generators for antifreeze have not yet been reported.

Embodiment 1

[0020] Example 1: The smoke generator provided by the present invention mainly includes a smoke generating system and an automatic temperature control ignition system, wherein: the smoke generating system includes a barrel body 1 with a barrel cover, the size of the barrel body 1 can be prepared according to different needs, and the inner side of the barrel body 1 There is a smoke guide net 4, a combustion-supporting agent placement area 2, a flame-retardant placement area 3 and a conduit 7 with a lead inside; the smoke-guiding net 4 is located between the flame-retardant placement area and the barrel 1, in order to be more conducive to smoke discharge, guide A smoke guide groove is preferably arranged on the smoke net 4; the combustion-supporting agent placement area 2 and the combustion-resistant agent placement area 3 are filled with combustion-supporting agent and flame-retardant respectively. The combustion-supporting agent placement area 2 is located in the middle and l...

Embodiment 2

[0027] Example 2: The control circuit of the smoke generator: at least includes an automatic temperature control ignition unit D1 and a combustion-supporting smoke exhaust unit D2. When equipped with an atomization system, it also has an atomization unit D3, wherein: the automatic temperature control ignition unit D1 is mainly composed of a temperature sensor, an upper The bias current resistance R1, the relay K2 and the ignition heating wire Rw are connected by lines; the control circuit of the smoke generating system is a combustion-supporting smoke exhaust unit D2, which mainly consists of a smoke intake and exhaust fan M1 and a smoke exhaust fan M2 connected in parallel with it, and a combustion-supporting fan M3 and a timer T2 connected in series with it; the control circuit of the atomization system is an atomization unit D1, which is mainly composed of a voltage-stabilizing capacitor C2 and an atomizer W1 and / or an atomizer W2. Among them: the power supply Vcc1 is 12V ...

Embodiment 3

[0030] Example 3: For the filling of smoke generators for frost protection in tea gardens, for example, when the radius of the bottom surface of the barrel 1 is 30cm and the height is 60cm, when placing the fuel, first spread a flame retardant with a thickness of about 10cm within the scope of the smoke guide net 4 at the bottom of the barrel, and then Then, take the center of the barrel as the origin, and spread about 5cm of combustion accelerant (about 500g) in a circle with a diameter of 15cm. Spread 5cm of flame retardant around and on the combustion accelerant, and cover with the lid, so that the combustion ventilation pipe 5 and the smoke guide net 4 just touch the flame retardant. Then, the flame retardant is filled between the smoke guide nets 4 in the barrel 1 through the two smoke outlet pipes. The oxidant placement area is connected to a conduit 7 with a lead wire inside for placing the lead wire for ignition. The lead wire is placed on the side of the oxidant clo...

Abstract

The invention provides a tea garden frost-proof method and a frost-proof smoke generator, and belongs to the technical field of late frost freezing disaster prevention in the fresh leaf picking stage of a tea garden. The frost-proof smoke generator is characterized in that the frost-proof smoke generator comprises a fuming system and an automatic temperature-control ignition system, can be connected with an atomizing system and is mainly used for making smoke between tea gardens and on other crops, so that the smoke spreads on tree crown surfaces; combustion-supporting agents and flame retardants serve as smoke generation sources, the smoke is purified through a filter, and mist of antifreeze or film-forming agents sprayed from an atomizer is also used, so that the frost-proof smoke generator has the advantages of being multi-freeze-proofing, high in heat efficiency and long in combustion time, having automatic temperature sensing functions and the like. The frost-proof smoke generator is simple and practical, simple to operate, safe, reliable, good in anti-freezing effect and high in popularization value.

Description

technical field [0001] The invention belongs to the technical field of protection against late frost and freezing damage during the picking period of fresh leaves in tea gardens, and specifically relates to a method for reducing the freezing damage of fresh tea leaves and an anti-frost smoke generator by generating smoke to prevent late frost from forming on the crown of tea gardens. Background technique [0002] In recent years, tea gardens have suffered from late frost damage during the picking period. For example, on March 18, 2010, more than half of the tea gardens in Zhejiang Province suffered severe late spring frost damage. Nearly 1.5 million mu of tea gardens, including West Lake Longjing, were frozen, and the loss reached 17 billion. Spring tea in Jiangsu, Anhui, Fujian, Jiangxi, and Hunan provinces also suffered from varying degrees of freezing damage. Among them, the frozen tea gardens in the northwestern and eastern Fujian tea areas in Fujian also exceeded 1 mill...
