Difficulties and Countermeasures of plant factory

From the national level, we all know that from 04 to 15 years, the Central Document No. 1 to develop modern agriculture to protect national food security, to ensure the effective supply of agricultural products, as the country's long-term development strategy. How to protect? Nothing more than to increase food production and increase the supply of food. From an international perspective, the United Nations Population Fund announced the global population in 2014 was 7 billion 700 million. According to the United Nations forecast that in 2050 the global population reached 9 billion 600 million in 2100 will reach 11 billion, will increase the population of 50%, we need to increase the supply of food and agricultural products. Liu Wenke, researcher at the Institute of agricultural environment and sustainable development, Chinese Academy of Agricultural Sciences, at the second forum on agricultural lighting.

The following is the speech record:

Development background of plant factory

By the end of the twenty-first Century, the increase in the population of the world or in our country was not only a demand for the quantity of agricultural products and food, but also a sharp increase in the quality of safety. First of all, from the supply side of agricultural products to analyze its supply capacity.

First, the country's agricultural production system, field production, its production capacity and stability in the lower. Why? The first is the decline in resources, from the quantity and quality of agricultural production resources, such as land, water and fertilizer, human resources, quantity and quality are declining.

Secondly, the pollution of agricultural environment, frequent natural disasters, large seasonal interference. The field agriculture was greatly disturbed by the season, and the North could not carry out the field agricultural production in winter.

Three is the ability of human intervention is poor, production capacity gradually in the absence of.

Based on the above reasons, we hope that the facilities of agriculture, one of the low-end facilities in agriculture, in our country as a plastic bag greenhouses, solar greenhouses. Its production capacity and stability is relatively poor, the facilities are relatively simple, the ability to control human intervention is relatively poor. The potential of increasing production and stable production is limited, how to do? Combined with the development of our technology, the solution can only be like this: we can upgrade the agricultural production system, upgrade the level of agricultural equipment, the development of agriculture with the concept of industry. This sentence is proposed to Premier Li Keqiang in 2015, by means of engineering technology and equipment greatly promote the quality and efficiency of agriculture, only in this way, we can use the limited resources and limited space to produce more food and food.

Two plant factory. In this context, the plant factory came into being. Plant plant development is very fast, it should be grateful to the two scientists. In the world, Japan's former president of Chiba University Professor Feng in the ancient tree, he is the founder and advocate of Japan and the world plant factory technical equipment and industrial development, published the "artificial light", "plant factory too light by plant factory" and other works. In Chinese, plant factory technical equipment and industrial development is the founder and advocate Dr. Yang Qichang of the Chinese Academy of Agricultural Sciences, plant plant technology and agricultural LED lighting technology he advocated in the beginning of this century, has published several books, will be published in 2016 "horticultural semiconductor lighting".

The definition of plant plant is to realize the continuous production of crops by means of high precision environmental control in the facility, which is not restricted by natural conditions, and is a kind of efficient agricultural production mode. It is mainly divided into two categories, one is the artificial light plant plant and the two is the sunlight plant factory. Figure two shows the lower left corner of the picture is the artificial light plant, the lower right corner of the sun light plant.

We can take a look at the horticultural development process (Figure 2), in the field of agriculture by relying on the weather to plastic greenhouses, simple fluorescent lamps, greenhouse and greenhouse to linkage now artificial light plant factory. It can be found that this is through the improvement of the sealing structure of the enclosure and the improvement of automation level and control level. From this development context, the ability of human beings to control agricultural production process is to enhance the use of engineering equipment to enhance the.

Advantages of plant plants

Plant factory has many advantages:

First, it is not affected by the external climate, production capacity is relatively stable;

Two is the land and space resources utilization efficiency is relatively high;

Three is its production factors, the degree of automation is relatively high, can be planned production, production is relatively high;

Four is one of the benefits of a more natural - no pollution, basically it does not occur pests, no pesticides, but also can eliminate heavy metals;

Five is the nutritional composition of agricultural products can be regulated, in the field, the nutritional quality of vegetables is very poor controllability. Under the conditions of facilities, we can mobilize all the facilities management factors, production factors to improve the nutritional quality of vegetables, but also can increase the accumulation of beneficial nutrients;

Six is to meet the special needs of crop production, such as islands, space agriculture;

Seven is the size can be large and small, omnipotent, it uses a lot;

Eight is the adoption of plant LED lighting technology equipment, which is its advantage. Because LED lighting can greatly enhance the efficiency of plant space, improve production efficiency;

The nine is a plant plant to adopt a title of technical equipment, so the degree of automation is reflected.

Difficulties in plant plant technology development

I personally think that the development of plant plants have these characteristics, its development goals, mainly real
