Description
Technical field
The invention belongs to field of agricultural cultivation, are related to a kind of implantation methods of Chinese cabbage.
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 lamp sodium
Light effect is low, and spectrum is single, high energy consumption and fever is serious, cannot carry out multilayer cultivation, therefore low space utilization.Fluorescence later
The new type light sources such as lamp, LED light are also applied in vegetable hydroponic plantation in succession.
Currently, Chinese cabbage multi-level facility is cultivated mainly based on LED light, and based on more energy-efficient red and blue LED spectrum, but
Due to industry bottleneck, there is a problem of light quality unevenness, this is unfavorable for scale, standardized production.In addition, to keep standardization
Management, majority of plants factory LED height is kept constant, generally from cultivation bed 30-60cm, so in order to ensure that Chinese cabbage gives birth to
The long later stage can obtain enough intensities of illumination and illuminating area, have to provide far above required illumination in Chinese cabbage Seedling Stage
Intensity and illuminating area cause to grow early period in Chinese cabbage, and most of light source all flogs a dead horse, and is finally translated into thermal energy, and excessive
Thermal energy then need air-conditioning etc. cool down tool exhaust.In the plant factor of uniform height, Chinese cabbage makees pakchoi production, often produces
100g pakchois take around 1.0-1.5 kilowatt hour electric energy, make Chinese cabbage production, and the period is long, and it is fresh often to produce 100g leaf-heads
Weight, takes around 0.8-1.2 kilowatt hour electric energy, since energy consumption high heat is big, needs cooling system heat extraction, further increase kind
The cost of plant.In addition, Chinese cabbage produces as Chinese cabbage, easily there is " tipburn " phenomenon, cause yield and quality to decline, equally
Also increase cost.The cultivar of plant factor is leaf vegetables mostly at present, for the cropping pattern of packet class vegetables
But seldom research, on the one hand since energy consumption is big, another aspect packet is more demanding for facilities environment, such as nutrient solution, light source, temperature
Spend etc., the phenomenon that under the facilities environment of single-mode, being unfavorable for packet, often result in packet difference or not packet.
In conclusion deficiency existing for the existing Chinese cabbage planted in plant factor is：1. energy consumption is big, planting cost is high；
2. the facilities environments such as nutrient solution, light source, temperature used in each growth phase of Chinese cabbage are consistent, growth cycle is slow, and packet is of poor quality
Even not packet；3. Chinese cabbage quality is low, need to use nutrient solution in planting process so that content of nitrite exists in ripe Chinese cabbage
4.5-5.5mg/kg, close to the content of even higher than pollution-free vegetable standard nitrite, Chinese cabbage is calciphile, in calcium deficiency
In the case of, " tipburn " phenomenon easily occurs, generally between 8-10%.
