Rice seedling raising carpet type plastic disc

Abstract

The invention discloses a rice seedling raising carpet type plastic disc and belongs to the materials used for agriculture. Multiple potholes are uniformly formed in the rice seedling raising carpet type plastic disc, a through hole is formed in the bottom wall of each pothole, an enclosure frame is arranged on the lower side portion of the edge folding portion of the periphery of the rice seedling raising carpet type plastic disc in the vertical direction, the bottom end face of the enclosure frame is flat with the bottom end face of each pothole, a groove protruding upward is formed in the central position of the bottom wall of each pot hole and at the periphery of each through hole, and cross grooves protruding upward are formed at the periphery of the bottom wall of each pothole and at the outer side position of each groove. By means of the rice seedling raising carpet type plastic disc, the embellish gas containing moisture and oxygen in seedbed soil can be conveyed into the soil at the bottom of each pothole conveniently and reliably for being supplied to the growth of the seedlings, and the disc has the advantages of being novel in structure, reasonable, simple, good in seedling operation quality, few in operation faults and reliable to use.

Description

technical field [0001] The invention belongs to agricultural materials, and mainly relates to a blanket-type plastic tray for rice seedling raising. Background technique [0002] Rice seedling-raising blanket-type plastic tray is one of the most used seedling trays in rice seedling raising operations in my country at present. Because of its light weight, low price, and convenient use, it is very popular among rice seedling farmers. In the process of rice seedling raising, rice seedlings need to continuously absorb water and oxygen from the seedbed soil under the blanket plastic seedling tray, and the supply of water and oxygen is through the blanket type through the dewetting gas containing moisture and oxygen. The through hole on the bottom wall of the nest on the plastic tray enters the nest and is supplied to the roots of the seedlings. However, due to the structural design defects of the existing blanket-type plastic seedling tray, a large amount of dewetting gas in the ...

Problems solved by technology

In the process of rice seedling raising, rice seedlings need to continuously absorb water and oxygen from the seedbed soil under the blanket plastic seedling tray, and the supply of water and oxygen is through the blanket type through the dewetting gas containing moisture and oxygen. The through hole on the bottom wall of the nest on the plastic tray enters the nest and is supplied to the roots of the seedlings. However, due to the structural design defects of the existing blanket-type plastic seedling tray, a large amount of dewetting gas in the soil of the seedbed is released from the four sides of the plastic seedling tray. The surrounding area is lost, and the through hole under the nest is also easily blocked by the soil of the seed bed, and the remaining small amount of dewetting gas containing moisture and oxygen cannot enter the nest, which affects and reduces the quality of rice seedling raising operations
