Seedling raising yard of hard-base permeable seedling bed

Abstract

A seedling raising yard of a hard-base permeable seedling bed comprises seedling beds, an inlet channel and a drain channel, wherein the seedling beds comprise a permeable layer and a hard foundationformed by leveling and compacting, the permeable layer is laid on the hard foundation and consists of a fine gravel layer and a fine sand layer; surrounding ridges are arranged around the seedling beds, and the seedling beds are arranged in parallel; a water inlet channel is arranged on one sides of the seedling beds, and channel gates are arranged in the water inlet channel, and communicate witha water pipe; water inlets are arranged on the surrounding ridges on the water inlet channel side, and communicate with the water inlet channel to irrigate the seedling beds; a drainage channel is arranged on the other sides of the seedling beds, and water outlets are arranged on the surrounding ridges on the drainage channel side, and communicate with the drainage channel to drain the seedling beds; and tractor roads are paved on at least one sides of the seedling beds. The seedling raising yard adapts to the new mode of mechanized seedling raising and transplanting in double-cropping rice areas, can meet the requirements of high-density seedling raising, facilitates unified management of seedling raising and is low in cost.

Description

technical field [0001] The invention relates to the technical field of seedling raising, in particular to a seedling raising workshop for large-scale seedling raising with hard-based permeable seedling beds. Background technique [0002] Traditional rice seedling raising adopts a decentralized artificial seedling raising model. This traditional model requires a lot of labor, low efficiency, and it is difficult to guarantee the quality of seedlings. It cannot meet the needs of mechanization, standardization, and socialized services of seedling raising, resulting in low rice planting benefits. With the rapid advancement of industrialization and urbanization, a large number of young and strong rural laborers have migrated to cities, resulting in a structural shortage of rural labor force, and the contradiction between supply and demand of agricultural production labor has become increasingly prominent. Farmers are not very enthusiastic about planting rice. phenomenon is widespr...

AI Technical Summary

Problems solved by technology

Among them, the management of seedlings in the cement factory is not easy to maintain water and moisture, the number of water spraying is high, the water is easy to lose, and the water consumption is large; when the early rice seedlings encounter the bad weather of "cold spring", it is impossible to use natural water to keep warm and control the temperature, and the seedlings are prone to Frostbite and frostbite will affect the quality of seedlings

Seedling field seedling management, poor working environment, high labor intensity, not conducive to mechanized operations; poor air permeability, not conducive to the growth of seedlings, prone to root rot, especially in high temperature and high humidity weather, easy to cause various diseases and insect pests

Seedling raising in greenhouses requires a large investment and high management costs; the seedlings are poorly adapted to the field environment after transplanting, which is not conducive to timely greening of the seedlings after transplanting
