Rice planting bowl seedling raising tray and preparation method thereof

Abstract

The rice planting pot seedling raising tray and its preparation method belong to agricultural production means and manufacturing technology; the seedling tray material is composed of rice straw powder of different weights, water-soluble bio-emulsion, micro-fertilizer nutrient medium soil, nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, fungicide and conditioning agent. The composition of the acid agent is prepared through the process of rice straw crushing, mixing and stirring, hot pressing, drying and setting; the seedling tray can be planted in the paddy field together with the rice seedling and the pot block, and can be degraded in the paddy field. After the rice seedlings are transplanted, there is no slow seedling period in the paddy field, and they are rich in nutrients, beneficial to crop growth, fertilizing soil fertility, and reducing production and manufacturing costs.

Description

technical field [0001] The invention belongs to agricultural production materials and a preparation method thereof, and mainly relates to a raw material and a manufacturing technology of a rice planting bowl and a seedling-raising tray used in rice seedling raising and planting. Background technique [0002] At present, the seedling pots used in agricultural production include plastic pots, paper pulp pots and resin pots. There are many types of arrangement of plastic pots and trays, but no matter which form can be directly transplanted by machine, manual throwing or secondary transplanting is required, which is labor-intensive and time-consuming, and the seedlings are poorly established and easy to drift; paper pulp pots are used The papermaking process is shaped by adsorption, and the cost is low, but the wet strength of the pulp pot is low, and the seedlings are too rotten before the end of the seedling period, and machine transplanting cannot be realized; the resin pot h...

AI Technical Summary

Problems solved by technology

There are many types of arrangement of plastic pots and trays, but no matter which form can be directly transplanted by machine, manual throwing or secondary transplanting is required, which is labor-intensive and time-consuming, and the seedlings are poorly established and easy to drift; paper pulp pots are used The papermaking process is shaped by adsorption, and the cost is low, but the wet strength of the pulp pot is low, and the seedlings are too rotten before the end of the seedling period, and machine transplanting cannot be realized; the resin pot has good seedling quality and can be planted mechanically. Very complex, high processing precision, large investment, and expensive resin bowls, difficult to popularize and apply

Plastic bowls and resin bowls have poor water retention and need to be watered repeatedly, wasting water resources

Plastic bowls and resin bowls need to be recycled and carefully kept, which increases management costs
