Precise digitized seedling system

Abstract

The invention discloses a precise digitized seedling system. Temperature, humidity, water (atomizing periods), gas (oxygen and CO2), fertilizers (inorganic slat and PH value), lights (leaf surface illumination intensity) and critical factors all which impact on plant seedling and growth and are involved in plant atomizing seedling are comprehensively and automatically regulated and controlled by the precise digitized seedling system. When seedlings of tobaccos, flowers and other plants are grown by the precise digitized seedling system, the seedling periods can be shortened, more robust seedlings can be cultivated, and the seedling space is saved; besides the precise digitized seedling system is efficient, reduced in cost, green and environmentally friendly.

Description

technical field [0001] The invention relates to the field of plant seedling raising, in particular to a digital precision seedling raising system. Background technique [0002] Modern facility agriculture originated in the 1950s and is the product of the development of modern scientific theories and technologies. The basic theory of modern facility agriculture is the "mineral nutrition theory" of plants put forward by German scientists in the 19th century. In 1842, J.von Liebig gave a report entitled "Chemistry Applied to Agriculture and Physiology" at the American Association for the Advancement of Science. Since then, the mineral theory of plant nutrition has gradually been accepted by people. From about 1851 to 1856, J.-B. Busengo used sand culture to study the mineral nutrition of plants, and in 1699 R.B. Woodward studied the nutrition of mint plants by hydroponics. J.von Sachs in 1860, W. Knopp in 1861 laid the modern hydroponics technology. Another basic technology...

AI Technical Summary

Problems solved by technology

The current tobacco greenhouse (seedling factory) in my country adopts the floating seedling cultivation method, which has cumbersome management, many procedures, and many labors; tobacco growth factors such as light, temperature, humidity, and fertilizer are significantly affected by various objective variables, and it is difficult to control; seedlings are not neat , requires multiple thinning and replenishing seedlings; the growth period varies greatly, and it is difficult to control the transplanting period; the hardening operation is cumbersome, difficult to control, and sometimes damages the tobacco seedlings; especially in terms of the quality of the tobacco seedlings, the root system of the tobacco seedlings is not developed enough and the stems are slender , the uniformity is not high; the disease damage rate is high; the seedling period is too long after transplanting

[0005] The main problem of cultivating flowers in greenhouses, greenhouses, and plant factories is that seedlings cannot emerge normally, and seedlings often wither and deform.

The root causes of these phenomena are mainly: 1) The agricultural expert system is not perfect, the basic database is incomplete, and there is a lack of comprehensive and complete technical integration

2) The decision-making model of the agricultural decision-making system is not scientific, representative, and logical enough

There is no comprehensive analysis of the plant nutrition and physiological mechanism of factors such as water, fertilizer, gas, heat, and light that affect plant growth and development for specific plant species, ignoring the balance and coordination mechanism of water, fertilizer, gas, heat, light and other factors, often focusing on single-factor control, and cannot guarantee each factor. Coordinate and unify the needs of the suitable growth and development environment of plants; the grasp and application of individual technologies are not flexible, and the general mechanism and operation law of water, fertilizer, gas, heat, light and other factors that affect plant growth and development cannot be accurately grasped, and scientific principles cannot be established. Flexible control parameters, unable to flexibly use individual technologies

3) Unreasonable matching of functional components, resulting in reduced efficacy or even loss of function

4), the control is not precise

[0007] However, this method still only involves the regulation of basic parameters such as temperature and humidity of seedlings, and does not involve the intervention and regulation of important factors that affect seedlings such as water, air, fertilizer, and light.
