Preparation method of reinforced mechanical rice transplanting seedling raising film

Abstract

The invention provides a preparation method of a reinforced mechanical rice transplanting seedling raising film. The method comprises the following steps that firstly, linen fiber and hemp fiber are placed into an opener proportionally for opening to form synthetic fiber; then, the synthetic fiber is fed into a carding machine through a transport groove for carding and then fed into a lapping machine for lapping; after lapping, the fiber enters a random machine through a conveyor belt for airflow random web forming; a sizing agent is added into an impregnating machine, the web is fed into the impregnating machine through a conveying curtain for impregnating and bonding to form the film, the film is fed into a drying machine through a conveyor belt to be dried, and a weed killer and a seedling strengthening agent are laid on the surface of the dried film; after drying is performed again, slitting and rolling are performed through a rolling machine, and storage is achieved. The seedling raising film produced through the method is low in cost, the film can be degraded after seedling raising is performed, the film has the properties of being breathable, achieving heat preservation and moisture preservation, strengthening seedlings, improving the fertilizer efficiency and the like, no adverse effect on soil is generated, ecological environment protection is facilitated, and the film is suitable for mechanical rice transplanting seedling raising.

Description

technical field [0001] The invention relates to the technical field of seedling raising, in particular to a preparation method of an enhanced machine-transplanted seedling raising film. Background technique [0002] Rice is the food crop with the largest planting area, the highest yield per unit area and the highest total output in my country. Doing a good job in rice production has a decisive impact on the realization of food security goals. Vigorously developing the mechanization of rice production can effectively compete for farming time, resist the impact of natural disasters, and save production costs. The promotion and use of rice transplanters is a key link in the development of rice planting mechanization, and it is expected to completely change the situation of traditional rice planting in my country "facing the loess and back to the sky, bending over and bending arms for thousands of years". At present, the main restrictive factors in the promotion process of rice...
