Rapid stereoscopic soilless rice seedling growing technology

Abstract

The invention relates to a rapid stereoscopic soilless rice seedling growing technology. The technology includes the steps that plant straw ferment powder, turf soil, coconut shell powder and other materials are made into a seedling growing matrix, seeds are sown into a hard seedling growing matrix tray, first-step darkroom germination acceleration is performed for 3 days, the room temperature is kept ranging from 30 DEG C to 33 DEG C, and a darkroom terrestrial heat supply mode is adopted for warming; only scattered light is adopted for a stereoscopic rice seedling growing greenhouse which is kept shady, bright and ventilated, an upper cover and a ventilation opening are automatically opened and closed, the temperature is kept being a room temperature ranging from 28 DEG C to 30 DEG C, and the humidity is kept being 85%, wherein the whole seedling growing time ranges from 10 days to 12 days, and the height of seedlings ranges from 12 cm to 13 cm; the seedlings with the height ranging from 12 cm to 13 cm are transplanted into a natural lighting greenhouse, hardened for 4-5 days at a normal temperature and then inserted into a field, wherein the whole seedling growing process lasts for 15 days to 20 days. According to the technology, non-renewable soil resources are saved, the environment is protected from being damaged, and crop straw and other waste resources are reutilized; the use space of the seedling growing greenhouse is saved, the room temperature, humidity, ventilation, illumination and other conditions of the greenhouse are automatically controlled, the seeding growing period is shortened, the seedling survival rate is increased, and the seedling quality is improved.

Description

technical field [0001] The invention relates to a rice seedling raising technology, in particular to a preparation method of the soilless rapid three-dimensional rice seedling raising technology. Background technique [0002] my country is a large agricultural country, and agricultural economy occupies a major position in the national economy. Since the reform and opening up, the state has invested a lot of money and material resources to ensure food security, engaged in the construction of farmland water conservancy and the development of paddy fields, and supported farmers to grow rice. Significant improvements have been made in rice area, rice variety improvement, and rice planting technology, which have played an important role in ensuring my country's food security. So far, my country's rice planting technology and economic benefits per unit area still have a certain gap compared with developed countries such as Japan and South Korea. Especially the seedling raising t...
