Preparation method of reinforced mechanical rice transplanting seedling raising film

Abstract

The preparation method of the enhanced machine-transplanted seedling-raising film provided by the present invention includes the following steps: firstly put the flax fiber and the hemp fiber into the opener in proportion to open to form mixed fibers; After carding by machine, it is sent to the laminating machine to lay the net; after the net is laid, it enters the random machine airflow through the conveyor belt to form a net; add slurry in the impregnating machine, and send the net to the impregnating machine through the conveying curtain for dipping and bonding to form a film. The film is sent to the drying machine through the conveyor belt for drying treatment. After drying, the herbicide and seedling strengthening agent are laid on the surface of the film; after drying again, it is cut and rolled by the winder, and put into storage. The cost of the seedling raising membrane produced by this scheme is low, the membrane can be completely degraded after seedling raising, has good performances such as air permeability, heat preservation, moisture retention, seedling strengthening, and fattening, and will not cause adverse reactions to the soil, which is conducive to the protection of the ecological environment and is especially suitable Machine transplanted rice seedlings are used.

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...
