Description

Technical Field

[0001] The utility model relates to the technical field of crop cultivation, in particular to a ground film for multi-year no-tillage intercropping of flue-cured tobacco and rapeseed. Background Art

[0002] Tobacco is the main cash crop grown on a large scale in the southwest region and plays a vital role in the income of farmers in the southwest region. However, with the increasing requirements for standardized tobacco planting, there are strict standards in each link, such as the amount of fertilizer, the height and width of ridges, film covering, opening transplant holes, etc. However, with the decrease in the permanent population in rural areas, there are not enough people for standardized tobacco cultivation, resulting in the failure to make good preparations before transplanting during the tobacco seedling transplanting season, which will cause tobacco transplanting to miss the best season.

[0003] At the same time, flue-cured tobacco and rapeseed are the main cash crops grown on a large scale in the southwest region. Since the transplanting time of flue-cured tobacco overlaps with the mature harvesting time of rapeseed in April and May each year, the land planted with rapeseed cannot be planned to grow flue-cured tobacco. The land planned to grow flue-cured tobacco can only be idle in winter and rapeseed cannot be planted, resulting in a low land replanting rate. At the same time, it will bring about the contradiction between grain and tobacco, affecting food security and local economic development.

[0004] To reduce or simplify the amount of farm work during the tobacco transplanting period and provide rapeseed with the temperature required for growth, a multi-year no-till intercropping technology for flue-cured tobacco and rapeseed is proposed. Therefore, it is crucial to design a durable mulch film. Summary of the invention

[0005] In view of this, the purpose of the utility model is to provide a durable mulch film for multi-year no-till intercropping of flue-cured tobacco and rapeseed, which can overcome the problems of the prior art.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] The mulch film used for multi-year no-till intercropping of flue-cured tobacco and rapeseed is a black breathable mulch film with high degradation resistance and strength.

[0008] The aforementioned black breathable ground film with high degradation resistance is PE weed control cloth.

[0009] The aforementioned mulch film for multi-year no-till intercropping of flue-cured tobacco and rapeseed is provided with continuous tobacco seedling transplanting holes in the central area in the length direction of the PE weed-proof cloth.

[0010] The aforementioned mulch film for multi-year no-till intercropping of flue-cured tobacco and rapeseed is characterized in that the tobacco seedling transplanting holes include a first transplanting hole and a second transplanting hole, and the hole spacing between the first transplanting hole and the second transplanting hole is half of the tobacco plant spacing.

[0011] The aforementioned mulch film for multi-year no-till intercropping of flue-cured tobacco and rapeseed has a hole diameter of 14-15 cm for transplanting tobacco seedlings.

[0012] The aforementioned mulch film for multi-year no-till intercropping of flue-cured tobacco and rapeseed is characterized in that the edges of the first transplanting hole and the second transplanting hole are respectively connected with cut circular pieces forming the first transplanting hole and the second transplanting hole.

[0013] The beneficial effects of the utility model are:

[0014] In order to meet the multi-year no-till intercropping technology of flue-cured tobacco and rapeseed, the utility model specially designs and develops a black breathable ground film with high degradation resistance and strength suitable for the technology. The PE weed-proof cloth that can be purchased on the market and can be processed and customized according to requirements is preferred. The PE weed-proof cloth has the functions of increasing ground temperature, preventing and controlling weeds, and being water-permeable and breathable. It has strong corrosion resistance and can be exposed to the sun for up to 10 years without rotting and is not easy to be damaged. It provides a basic guarantee for many years of continuous no-till use. At the same time, the rapeseed sowing to harvesting cycle can be effectively shortened by increasing the winter temperature, and the tobacco planting land can be avoided from being idle in winter; tobacco planting holes with specified plant spacing are pre-opened on the weed-proof cloth, which reduces the positioning and film-breaking processes on the ground film compared to the existing transplanting, and further reduces the labor; at the same time, the material of the weed-proof cloth is not easy to be scratched, so it is not easy to be damaged when pulling out the tobacco stems and cutting the grain and grass crops.

[0015] In order to avoid the density of transplanting tobacco in the same position during continuous cropping, that is, when planting rapeseed, the cut circular piece of the first tobacco seedling transplanting hole or the second tobacco seedling transplanting hole pre-opened when customizing the PE weed-proof cloth is connected to the PE weed-proof cloth. In this way, during the tobacco planting stage, the cut circular piece of the unplanted tobacco seedling transplanting hole will be restored to cover the tobacco seedling transplanting hole. This can prevent grass from growing at that position, reduce the weeds from absorbing nutrients from the ridge body, and retain the function of the mulch film.

[0016] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and research, or can be taught from the practice of the present invention to some extent. The objectives and other advantages of the present invention can be realized and obtained through the following description and claims. BRIEF DESCRIPTION OF THE DRAWINGS
