Background

In rural areas of China, large-area crops such as corn, sorghum, wheat and the like are planted with the serving of the Chinese medicinal herb, and the problem of headache is caused by the treatment of straws after the crops are harvested. In some areas of China, due to the limitation of short frost-free period, farmers often burn straws in the most economical and rapid mode to plant the next crop in the season. The waste incineration of the crop straws not only causes great waste of resources, but also brings a series of hazards, such as environmental pollution, health hazard, fire hazard, damage to soil structures, reduction of farmland quality and the like. Although the three kingdoms forbid the burning of the straws and invest huge manpower and material resources for propaganda and supervision, the burning of the straws is forbidden frequently.

The straw burning is avoided, and the current situation rises to the national policy level, so that the solution can find the solution of environmental management and ecological civilization construction in China. However, how to put an end to the burning of the straw and make the straw transit from the 'waste' attribute to the 'resource' attribute, so that the resource in the misplaced place can play a value is a problem which needs to be considered currently. The utility model relates to a straw long fiber seedling growing rod is just with simple processing post-production environmental protection product of straw. With the continuous maturity of the product and the related integration technology, the product not only can directly benefit the agriculture, forestry and gardening, but also can create a more practical and perfect modern organic dry farming agriculture mode, a difficult site afforestation and greening mode, a sponge city construction mode and the like, and provides technical support for agriculture and forestry development and city construction in China.

The straw long fiber seedling raising rod has the following technical advantages: the raw material for making the long-fiber seedling growing rod is crop straw. The straw is used as a renewable and decomposable resource, is developed in large scale year after year, cannot cause resource exhaustion, cannot cause environmental problems, and can greatly improve the yield and enrich the resource quantity along with the improvement of the soil environment; the development of the long-fiber seedling raising rod of the straw finds a new way for the crop straw to play the function of the straw. The processing and utilization of the straws can effectively reduce the burning of the straws and reduce the carbon emission, and has important significance for maintaining the beauty of the living environment of human beings and implementing the relevant policies and development economy of the Chinese Party; the straw is a product of green plants for photosynthesis, and is a byproduct of agricultural production, particularly grain production. The development of the seedling growing and planting technology of the long-fiber seedling raising rod of the straws can effectively return a large amount of straws to the farmland, and has the direct effects of increasing soil organic matters and improving and fertilizing the farmland; the application of the straw long fiber seedling raising rod technology can reduce plastic pollution, the rod seedlings can be planted integrally, and the straw long fiber seedling raising rod is slowly decomposed and continuously releases nutrients under the action of root systems, microorganisms and the environment after being planted. Therefore, by adopting the straw container rod integrated planting technology, the planting survival rate is high, the seedling reviving period is short, the plastic seedling raising pot can be replaced, the plastic pollution is reduced, and the dual purposes of economic development and beautiful environment are realized.

The technical advantages of the long-fiber seedling raising rod of the straw establish wide market demands, so that an automatic production line is the key and guarantee for large-scale application of the technology. Aiming at the hollow tubular characteristic of the straw long fiber seedling growing rod, the automatic production equipment adopting spiral extrusion molding is adopted, the straw material is continuously extruded and molded, but the straw long fiber seedling growing rod is required to be cut into various specifications and sizes according to the use requirement in the use process, so that the key technology of how to accurately saw and cut the continuously produced straw long fiber seedling growing rod is required to be solved.

Generally, the plastic pipe is sawed in an on-line follow-up sawing mode after being spirally extruded and formed, for example, the plastic pipe is sawed into sizes of 5 meters, 6 meters and the like in an on-line follow-up sawing mode after being formed, and similar follow-up systems are also available in the market. But the straw long fiber seedling culture container is not suitable for an on-line follow-up sawing mode due to the characteristics of the straw long fiber seedling culture container.

Firstly, the straw long fiber seedling raising container is lighter and more handy in agriculture and forestry seedling raising use, the common cutting size is 40-60 mm, so that a rapid continuous production process and an intermittent cutting process conflict, the cutting action completion speed obviously cannot follow the speed of a continuous production rod, so that the side thrust is generated between a saw blade and a material due to large extrusion, and the sawing of the straw long fiber seedling raising rod with a small size cannot be realized; secondly, the main components of the finished product rod are straw long fibers, the seedling raising rod after being produced is soft in texture, the long straw fibers penetrate through the seedling raising rod and are directly cut without being aired, the seedling raising rod is easily torn to be broken, the product deformation is caused, the yield is reduced, and the seedling raising rod needs to be sawed and cut after being aired.
