A method for cultivating rice machine-transplanted strong seedlings using substrate-type seedling trays

Abstract

The invention discloses a method for cultivating rice machine-transplanted strong rice seedlings by using matrix-type seedling trays, which includes the following steps: 1) determining the area of ​​seedling fields; If there is no land, choose hard land first, and if there is no soft land, choose soft land as the seedling field; after choosing hard land, a waterproof layer must be built around the seedling field; 3) Seed treatment; 4) Seedling tray placement: hard When cultivating seedlings in the ground blocks, place two substrate-type seedling trays along the length direction to form a pair, and place them along the width direction to form a group, so that multiple sets of seedling trays are placed; 5) Sowing: add seeds Sowing with a small precision seeder; 6) Covering soil: cover the soil after sowing, and the thickness of the covering soil is subject to the absence of seeds; 7) Fertilization: topdress the seedlings at the stage of one leaf and one heart, and use urea and potassium dihydrogen phosphate to prepare a nutrient solution , carry out foliar spraying, the present invention has improved the quality of seedling, reduces cost, protects environment.

Description

technical field [0001] The invention relates to a matrix-type seedling tray, in particular to a seedling raising method based on the matrix-type seedling tray. Background technique [0002] Seedling raising is the key link of rice machine transplanting technology. At present, rice seedling raising is developing from scattered open-field seedling raising to centralized facility seedling raising, floppy disk nutrient soil seedling raising to hard disk substrate seedling raising. The more widely used seedling raising methods in production include field centralized seedling raising (including plastic tray Nutrient soil or matrix non-woven fabric seedling raising, etc.), hard block hard disk (micro-spraying) seedling raising, modern factory seedling raising, etc. However, these seedling raising methods all require the use of seedling disks (floppy disks or hard disks), which greatly increases the labor, capital and space requirements for machine-transplanted seedling raising, and...

AI Technical Summary

Problems solved by technology

For example: sowing directly on the matrix-type seedling tray is easy to skip seeds, which is not conducive to uniform sowing; the matrix-type seedling tray has poor water retention capacity and is not resistant to washing; when using the matrix-type seedling tray to raise seedlings, it is easy to have insufficient fertility in the later stage, resulting in low seedling quality. Poor packing of seedlings; when growing seedlings in the field, the roots of seedlings easily pass through the substrate-type seedling trays and take root into the soil, which is not conducive to the handling of seedlings and other issues
