Mechanical rice-seedling planting, raising and transplanting method with tray and rice-seedling raising tray

Abstract

The invention provides a mechanical rice-seedling planting, raising and transplanting method with a tray and a full-bowl shaped mechanical rice-seedling raising tray for rice-seedling raising. The rice-seedling raising tray is manufactured from a degradable film sheet; a plurality of bowls which are arranged in an array form and concaved in the same side are pressed on the film sheet and equipped with quick-breaking parts; when in rice-seedling planting, the rice-seedling raising tray with rice seedlings is positioned into a rice-seedling box of a rice-seedling planting machine; the extracting width and longitudinal extracting quantity of the rice-seedling planting machine are adjusted to be equal to the width of the bowls in the rice-seedling raising tray; the bowls are separated from the rice-seedling raising tray when the rice-seedling planting machine works for transplanting and a rice-seedling extracting machine works for extracting the rice seedlings, and the bowls are inserted into a rice field together with the rice seedlings inside. With the adoption of the rice-seedling raising tray, the general belt type rice-seedling planting machine or the bowl shaped felt type rice-seedling planting machine applies, and the rice-seedling raising tray can be divided into blocks by bowls. With the adoption of the rice-seedling raising tray, the general felt type rice-seedling planting machine or the bowl shaped felt type rice-seedling planting machine can be adopted for transplanting the full-bowl rice seedlings together with the bowls; the transplanting mechanism is simpler than the general full-bowl shaped rice-seedling transplanting machine; the transplanting effect and late-stage growing completely reach the full-bowl type rice-seedling transplanting level.

Description

technical field [0001] The invention relates to the field of mechanized rice transplanting and seedling raising. Background technique [0002] The seedlings that rice mechanized transplanting uses at present have blanket-shaped seedlings, half-pot and half-blanket pot-shaped blanket-shaped seedlings and full pot-shaped seedlings. The first two methods are to use the roots of the seedlings to form a blanket to connect the seedlings into a rectangular blanket. When transferring, the blanket-shaped seedlings are taken out of the seedling tray, put into the seedling box of the rice transplanter, and then the seedlings are divided by the transplanting mechanism. And transplant to the field, this kind of mode all has certain injury to the root of rice shoot, and affects the growth of rice seedling after transplanting. The pot-shaped seedlings usually have no connection between the pots and the pots, and are independent of each other. After being cultivated in the special seedling...

Problems solved by technology

The first two methods are to use the roots of the seedlings to form a blanket to connect the seedlings into a rectangular blanket. When transferring, the blanket-shaped seedlings are taken out of the seedling tray, put into the seedling box of the rice transplanter, and then the seedlings are divided by the transplanting mechanism. And transplanted to the field, this kind of method all has certain damage to the root of rice seedling, and affects the growth of seedling after transplanting

The pot-shaped seedlings usually have no connection between the pots and the pots, and are independent of each other. After being cultivated in the special seedling tray, they are put into the seedling box of the special transplanting equipment together with the seedling tray, and then the transplanting equipment The advanced seedling picking mechanism takes the seedlings out of the bowl in the seedling tray and transplants them to the field without damaging the roots of the seedlings, and the seedlings grow well after transplanting. Seedling trays and sowing equipment are matched, and the technical requirements for seedling raising are relatively high, so it is difficult to popularize and apply
