Problems solved by technology

The core technology of rice machine transplanting currently used in my country is mainly the machine transplanting technology of blanket seedlings introduced from Japan, South Korea, etc., mainly using plastic seedling trays, which have problems such as high production costs, large storage space, and easy stacking of machine transplants.
[0004] In view of the problems existing in traditional plastic seedling trays, my country has carried out research on related biomass seedling trays since the 21st century, and developed a rice planting bowl seedling tray, which is a kind of rice husk powder as the main raw material and then added Nutrients, medicaments and binders are used as soil substitutes for seedling raising - plant matter artificially synthesized seedbed soil; at the same time, a pot seedling raising tray made of fiber material made of crushed rice straw as raw material and processed by specific molding has been developed. However, the seedlings raised in this kind of seedling tray need to be equipped with a corresponding pot cultivation transplanting machine to be transplanted, and the seedling tray has a large expansion rate when it encounters water. , seedling quality is poor, popularization is difficult, and the area of ​​popularization and application in our country is small

Abstract

The invention relates to the technical field of rice planting equipment and in particular relates to a method for manufacturing a rice machine transplanting seedling tray. According to the method, papermaking wastes and crop straws are taken as main raw materials, and the manufactured rice machine transplanting seedling tray has the advantages of degradability, no pollution and an effect of improving the paddy field fertility. Compared with a conventional rice machine transplanting seedling-raising plastic seedling tray in China, the seedling tray produced by the invention has a degradable function, can be inserted into the paddy field along with the rice seedlings during machine transplanting and is fully degraded, after the seedling tray substance is degraded, the seedling tray also has an effect of improving the soil fertility, the problem that lots of space and cost are needed for storage after usage of the traditional plastic seedling tray is solved, a seedling tray storage warehouse is not needed, and the seedling tray storage expense is saved. Moreover, the machine transplanting effect is good, the seedlings are not stacked, the seedling claws are not attached to the seedlings, and high-yield machine transplanting is realized. Compared with a plant pot seedling tray, the seedling tray disclosed by the invention is convenient to process, is not added with any coagulating agent and contributes to industrial production, the influence of seedling raising on the seedling growth is small, the seedling quality is good, the blanket forming property is high and the machine transplanting yield is high.

Description

technical field [0001] The invention relates to the technical field of rice planting equipment, in particular to a method for manufacturing rice machine-transplanting trays. The method uses papermaking waste and crop straw as main raw materials, and the manufactured rice machine-transplanting trays have the characteristics of degradability, pollution-free and improved paddy fields. The effect of fertility. Background technique [0002] Rice machine transplanting is the main development direction of modern rice farming technology in my country. It is of great significance to stabilize grain production, increase rice yield per unit area, promote large-scale rice production, and improve labor productivity under the conditions of rural labor force transfer and aging. Most of the soil used for machine-transplanted rice seedlings is excavated from the dryland plow layer and the surface loess of mountains and forests, causing irreversible damage to dryland resources and ecological ...
