Background
Seedling transplantation is a planting mode frequently adopted in agricultural production. Compared with a direct seeding planting mode without seedling raising, the seedling raising and transplanting divides the growth cycle of crops into two stages of concentrated seedling raising before transplanting and field growth after transplanting, on one hand, the planting time of the crops in the field can be shortened, so that the planting of the crops or the crop varieties with longer growth period in an area with determined accumulated temperature in one year becomes possible, and even the number of planted stubbles can be increased; on the other hand, the centralized seedling raising facilitates the seedling stage management, so that the seedlings are stronger and more tidy. Therefore, the seedling transplantation can realize the yield increase and income increase and is widely adopted in agricultural production.
Mechanical transplanting is adopted after seedling raising, the transplanting speed can be greatly improved, the transplanting cost is reduced, for example, on rice, compared with the traditional artificial transplanting, the transplanting efficiency can be greatly improved by adopting the mechanical transplanting technology after seedling raising, 40-50 mu of seedlings can be transplanted by one 6-row transplanter every day, which is tens of times of the efficiency of artificial transplanting every 0.5-0.6 mu of seedlings. The rice transplanting machine is widely applied to seedling plate seedling raising technology, the seedling raising technology is to utilize plastic seedling raising plates with consistent specifications to cultivate blanket-shaped group seedling blocks, the blanket-shaped seedling blocks are integrally transferred to a rice transplanter after being cultivated, and a plurality of seedlings are separated from the group-shaped seedling blocks by a separating and inserting device of the rice transplanter and inserted into soil. Under the operation mode of the transplanter, tidy and complete seedling blocks are the foundation of the mechanical transplanting, and if the seedling blocks are not good in blanket formation, the phenomena of root injury, seedling injury and seedling leakage in the transplanting process are greatly increased.
In order to make the 'blanket-shaped group seedling block' better coiled knot and easy to carry, researchers in rice cultivation research have studied various techniques for promoting the coiled knot of the seedling block. Patent CN201010207756.5 discloses a seedling raising technique with carpet added by non-woven fabric (hemp seedling raising film) made of hemp fiber, which adopts crop fiber such as hemp and the like and non-woven fabric technology to make base fabric, and when raising seedlings, the base fabric is laid on the bottom surface of a seedling raising flat plate and then covered with soil and sowed. After the hemp seedling raising film is laid in the seedling raising tray in advance, the seedling root system can penetrate through the non-woven fabric and intertwine with the non-woven fabric fiber, so that the intertwining tightness of the seedling root system is obviously improved, and the problem of seedling scattering is reduced. The defects that the non-woven fabric is very soft, and is easy to move when being paved on a seedling tray and sowed in an earthing manner, namely the flax seedling raising film and the bottom of the seedling tray can be formed to be in different positions, so that the flax seedling raising film is generally cut into a rectangle which is a little larger than the bottom of the seedling tray, the flax seedling raising film completely covers the bottom of the seedling tray after being enlarged, but the redundant flax seedling raising film is exposed after part of seedling raising soil is filled, and when the mechanical sowing is carried out on a production line, the part of flax seedling raising film is easy to wind on a brush for brushing soil, so that the mechanical sowing process is influenced; meanwhile, the exposed non-woven fabrics cause the edge to lose water more easily, and the seedlings in the seedling tray grow unevenly. Patent CN201811549361.6 discloses an integrated hemp film perforating machine seedling-transplanting tray, which is characterized in that during the preparation process of the seedling-raising tray, a flat-bottom plastic seedling-raising tray and a hemp seedling-raising film are respectively prepared, then an environment-friendly adhesive is used to fix the hemp seedling-raising film on the bottom surface of the seedling-raising tray, so that the hemp seedling-raising film completely covers the bottom surface of the seedling-raising tray, then the hemp seedling-raising film and the bottom surface of the tray body are punched by a perforating machine to form uniformly distributed small holes penetrating through the hemp seedling-raising film and the bottom surface of the tray body, namely the hemp seedling-raising tray is fixed on the tray in advance during the preparation stage. The technology can avoid the dislocation of the hemp seedling raising film during seeding and seedling raising, and the exposure of the hemp seedling raising film which is larger than the exposure formed at the bottom of the seedling raising tray for reducing the influence of the dislocation, but the seedling raising tray and the hemp seedling raising film are both used once, so that the seedling raising cost is greatly increased, and the waste pollution of plastics is aggravated.
The seedling raising base cloth is not only used for raising rice seedlings, but also adopted when raising seedlings of some horticultural plants, for example, when raising seedlings of turf, the base cloth is usually added on a seedbed firstly, the turf is sowed after being covered with soil, and the turf is lifted out of the seedbed together with the base cloth belt after being raised. The non-woven fabric base cloth is generally made of chemical raw materials, and is not degradable after being implanted into the ground, so that the ecological environment is greatly influenced.
