Method for raising rice seedlings with soft base and hard edges

Abstract

The invention provides a method for raising rice seedlings with a soft base and hard edges. The method comprises the following steps: orderly arranging seedling trays transversely into rows on a seedling surface which is prepared to be loose at the top and compact at the bas by combined positioning of a seedling tray positioning frame and hard flanges for assisting to arrange trays, and setting two long edges of the seedling trays from the outer side by virtue of the hard flanges, wherein the loose-top compact-base seedling field is formed by flattening and compacting a field ground to harden the surface and laying a thin layer of seedling soil on the ground, and the bottoms of the hard flanges are inserted into the compact part under the seedling surface of the seedling field. The method enables good combination of inside seedling trays and outside seedling trays, is beneficial to absorbing nutrition and moisture in the rice seedling growing process along with a good moistening effect; and the seedling carpet has a clean and neat boundary to improve the mechanical transplanting effect, and a soft seedling tray with low price and convenience in use and storage can be used more widely due to the low seedling cost.

Description

technical field [0001] The invention relates to rice planting technology, in particular to a dry seedling raising method for rice seedlings used in rice transplanters. Background technique [0002] Among the seedlings used in dry-raised rice transplanters, there is a kind of seedlings that are made of thin plastic sheets and are called floppy disks, which are neatly arranged in the seedling field, and seedling soil is added to the seedling trays, and then seeded, covered with soil, and irrigated to cultivate the seedlings. In this way, through the growth and knotting of the root system of the seedlings, the rectangular blanket-shaped seedlings or pot-shaped blanket-shaped seedlings are cultivated into sheets. The use of this seedling tray is low in price, easy to use and store, and other advantages make it widely used. But this kind of floppy disk seedling tray is easy to deform because the edge of the seedling tray is easy to deform during use, so that the shape of the out...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a rice seedling raising method with a soft bottom and hard edges, which can solve the problem of uneven width of the seedling blanket for dry seedling raising on a floppy disk, and can also have a good contact between the bottom surface of the floppy disk and the ground, reaching the standard of machine-transplanted rice seedlings
