Film-splicing seedling nursing method

Abstract

The invention discloses a film-splicing seedling nursing method comprising the following steps of (1) planting seedlings on a seedling bed, (2) cutting a plastic film at the length of 1 to 50cm larger than the width of the seedling bed and the width of 0.1 to 20cm larger than seedling spacing distance, and (3) forking well-cut thin film cutting mouths into the whole line of seedling and covering the ground between lines. Seedling transverse straight distance meets regular standards and straight lines are standard as possible as can; for instance, the width of the seedling bed is 150cm; the seedling transverse straight distance can be in a way that the plant distance can be 10cm and line distance can be 20cm; a plurality of cutting mouths are cut on one rectangular side of the thin film; the cutting mouth distance is the same as the seedling line distance; and the thin film is paved on each line in a consequent direction. By the use of the film-splicing seedling nursing method, high emergence rate can be achieved with the highest rate of 80%; short seedling nursing time can be achieved; seedlings nursed by the method are strong and tidy; the plants can grow quickly; seedling nursing time and spatial limitations can be reduced; and land utilization rate can be improved and great application prospect can be realized.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a method for cultivating seedlings by mosaic film. Background technique [0002] Rhubarb is mostly propagated by seeds, and the commonly used sowing methods include seedling transplanting and live broadcasting. In the traditional method of raising seedlings and transplanting, seedlings usually adopt the method of raising seedlings in the field: in the first and middle days of April, a 1.2m wide flat depression is made; horizontally in the depression, the depth of the ditch is 3-4cm according to the row spacing of 12cm; Spread the seeds evenly into the ditch with a distance of 2cm between seeds; cover with fine sand 2cm thick, cover with grass thatch or agricultural film, and remove the cover after emergence; strengthen seedling management, and press 50x25cm by the end of April in the following spring Transplant in the field with a row-to-plant distance; cut off the ...

Problems solved by technology

Using traditional seedling raising methods, the emergence rate is low, usually 20% to 40%, the seedling raising cycle is as long as 1 year, and the plants grow slowly
