Description

A light-transmitting vault thermal insulation device suitable for batch operations

technical field

The utility model relates to a light-transmitting arch insulation device suitable for batch operation.

Background technique

In order to increase the soil temperature, retain water and soil, preserve fertilizer, and improve fertilizer efficiency, the ground is usually covered with a film (mulch film), which has the functions of protecting roots and promoting growth. However, a large amount of plastic film covered in the field is difficult to recycle. After the crops are harvested, the plastic film remains in the soil and is difficult to degrade, causing pollution and damage to the soil. Especially with the spread of the plasticizer storm, will the plastic film fail to settle? The problem that the plasticizer content in the soil is too high and affects people's health is very worrying.

Plastic film is widely used in the cultivation of tobacco seedlings. Transplanting is a critical link in tobacco production. Tobacco farmers often list transplanting as one of the five major hurdles in tobacco production, which is of great significance. Because tobacco seedlings are particularly sensitive to temperature, if the ambient temperature is lower than about 8°C, it is easy to cause early flowering of tobacco seedlings, resulting in reduced harvest and quality, so plastic film is usually used during transplanting. Generally, according to the requirements of the transplanting time, deep plowing, fine harrowing, and high ridges are carried out on the plot in due course, and the tobacco seedlings are transplanted, covered with plastic film, and the plastic film sticks to the soil. Ponds were made on the same day, transplanted on the same day, and covered with film on the same day. In this way of transplanting, the growth space of the tobacco seedlings is very limited, and the plastic film will soon hinder the growth of the tobacco seedlings, so it is necessary to break the film and dig out the seedlings. Take it out. This method of operation is cumbersome, and the time limit is relatively strict (otherwise it is easy to cause the seedlings to burn close to the mulch film), and the operation of removing the seedlings is likely to cause the spread of diseases and damage to the tobacco seedlings.

Flue-cured tobacco "well cellar" seedling transplanting is a new way of transplanting film-mulched tobacco seedlings. First, ridges are covered with plastic film, and well cellars are drilled at specified intervals on the ridges covered with plastic film, and then tobacco seedlings are put into the holes. Use a small amount of fine soil to cover the root matrix of the tobacco seedlings. The leaves of the tobacco seedlings cannot protrude out of the hole. When the leaves of the tobacco seedlings have completely grown out of the hole, seal the hole and the mouth of the film with wet soil. Other management is the same as that of the conventional plastic film. In this way, the ridge surface and the plastic film are punched at the same time, and the tobacco seedlings grow in the "well cellar". Only in the non-perforated soil position to preserve the plastic film cover, the open form of the "well cellar" is not conducive to heat preservation, water retention and fertilizer conservation, and the effect is limited.

In fact, the period after membrane rupture and seedling removal is approximately from the end of February to the beginning of March each year. Tobacco seedlings often encounter some extreme weather (frost and ice disasters, etc.), and the existing cultivation methods cannot avoid the impact of extreme weather on tobacco. Damage to seedlings, resulting in reduced harvest and reduced quality of tobacco leaves.

Furthermore, no matter it is the traditional under-film transplanting or the "well cellar" transplanting, the plastic film is used. Since the plastic film is very thin, it cannot be recycled after a period of wind and sun. It is different from other crops in plastic film cultivation. Similarly, the unsolvable problem is that the mulch film remains in the soil, which cannot be recycled and is difficult to degrade, causing pollution and damage to the soil.

Example 1

The mulch film used in the prior art cannot recycle polluted soil and the environment. In order to increase soil temperature, retain water and soil, preserve fertilizer, and improve fertilizer efficiency, the ground is usually covered with a film. The film is usually a transparent or black PE film, and there are also green and silver films. For the newly unearthed seedlings, it has the functions of mulching roots and promoting growth. But mulch film planting covers a large amount of plastic film in the field. After the crops are harvested, the mulch film remains in the soil, which is difficult to recycle and degrade. It has caused pollution and damage to the soil, especially with the spread of the plasticizer storm, whether the inability of the plastic film to settle will lead to excessive plasticizer content in the soil and affect people's health is still being tested, which is worrying. Because the tobacco seedlings are particularly sensitive to temperature, plastic film is usually used in the transplanting process, which also has the above-mentioned problems. Not only that, but the plastic film that is tightly covered on the soil surface cannot give enough growth space for the tobacco seedlings, and it is easy to cause seedling burn. Even if the "well cellar" type transplanting is adopted, it is necessary to break the film and remove the seedlings in time to ensure the growth of the tobacco seedlings. Growth space, resulting in cumbersome operations and the spread of diseases, as well as damage to tobacco seedlings during seedling removal operations. Tobacco seedlings that have been filmed out are still unavoidable to be damaged by extreme disasters such as frost and ice disasters, resulting in early flowering and reduced tobacco leaf yield or quality.
