Description
Technical field
The invention belongs to field of agricultural cultivation, are related to a kind of implantation methods of ice dish.
Background technology
Plant factor is to realize crops anniversary quantity-produced high-efficiency agriculture system by high-precision environment control in facility
System is the temperature for utilizing computer to give birth to plant, humidity, illumination, CO2The environmental conditions such as concentration and nutrient solution carry out automatic
Control, make the growth of facility implants not by or the effort-saving production that is seldom restricted by natural conditions.Plant factor's multiple crop index is high,
Can whole year production, and avoid continuous cropping and hinder.Leaf vegetables is not easy to store, but needs whole year production to meet the market demand, therefore
Plant factor is particularly suitable for cultivation leaf vegetables.
In plant factor, the agricultural product quality of water planting is good, and pollution-free no agriculture is residual, and growth cycle is short, is conducive to plant and exists
It is produced under the conditions of extreme environment, is conducive to the limitation that agricultural breaks away from resource and environment, realizes the sustainable development of agricultural
Exhibition.By illumination source, plant factor can be divided into sunlight plant factor and artificial light plant factory, sunlight plant factor light source
All derive from sunlight；And artificial light plant factory can be divided into two kinds, be combined one is sunlight and artificial light, sunlight not
Artificial light is given when sufficient, this type plant factor is limited to cost limitation compared with power saving, and single layer cultivating stand makes space occupancy rate
It is not high；Another kind is the plant factor of complete artificial lighting, and initial artificial light source uses high-pressure sodium lamp, but high-pressure sodium light
Imitate low, spectrum is single, high energy consumption and fever is serious, cannot carry out multilayer cultivation, therefore low space utilization.Fluorescent lamp, LED later
The new type light sources such as lamp are also applied in vegetable hydroponic plantation in succession.
Currently, leaf vegetables multi-level facility is cultivated mainly based on LED light, and with more energy-efficient red and blue LED spectrum
Based on, but due to industry bottleneck, there is a problem of light quality unevenness, this is unfavorable for scale, standardized production.In addition, to protect
Hold standardized management, majority of plants factory LED height is kept constant, generally from cultivation bed 30-50cm, so in order to protect
The card plant strain growth later stage can obtain enough intensities of illumination and illuminating area, often have to provide remote height in the plant shoots phase
In required intensity of illumination and illuminating area, cause in plant strain growth early period, most of light source all flogs a dead horse, is finally translated into
Thermal energy, and excessive thermal energy then needs the cooling tool exhaust such as air-conditioning, further increasing energy consumption value.
Ice dish also known as fortune chloranthus herb, wheatgrass, ice leaf etc., Aizoaceae Mesembryanthemum one, biennial herb plant originate in south
It is non-, be the novel vegetable introduced in recent years from Japan, because its blade face on stem the bulliform cell of raw a large amount of similar " ice crystal " due to obtain
Name, since it is with unique shape and health-care efficacy, obtains being widely recognized as consumer on the market.Ice dish happiness is cloudy, no
Resistance to strong sunlight direct projection, root system is undeveloped, intolerant to waterlogging, and main plantation is in greenhouse at present, the research to its water culture technique
It is also at the early-stage, technology is also immature.In the plant factor of uniform height, 100g ice dishes are often produced, 2-3 thousand is taken around
Watt-hour electric energy needs cooling system heat extraction since energy consumption high heat is big, further increases the cost of plantation.
To sum up, deficiency is existing for the ice dish planted in plant factor at present：1. germination percentage is low, uneven emergence, unfavorable
Standardization, large-scale production in plant factor；2. energy consumption is big, planting cost is high；3. the battalion used in each growth phase of ice dish
The facilities environments such as nutrient solution, light source, temperature are consistent, and growth cycle is slow, and branch is slow and growth is abnormal；
