What is three dimensional cultivation? Benefits of three dimensional planting

It is to erect a bed in the heating greenhouse for multi-level three-dimensional cultivation, mainly to save space and use the existing thermal energy resources to cultivate more greenhouse crops. Tomatoes, potatoes, garlic, strawberries. Early-maturing watermelons, melons, etc. can be cultivated in greenhouses.

Here's a detailed introduction.

It can fully tap the potential of natural resources such as land, light energy, water source, and heat, and at the same time improve the utilization rate and utilization efficiency of artificial auxiliary energy.

It can make full use of land resources, improve the utilization rate of land resources, and effectively alleviate the contradiction between man and land and the contradiction between various crops competing for land. Through intercropping, intercropping, mixed cropping and other modes, the output of agricultural products per unit area can be greatly increased and the contradiction between food supply and demand can be alleviated. It can alleviate the pressure of residual chemical fertilizers and pesticides on the soil environment and water environment.

Benefits of Three-dimensional AgricultureThree-dimensional agriculture can fully tap the potential of natural resources such as land, light energy, water source, and heat, and at the same time improve the utilization rate and utilization efficiency of artificial auxiliary energy such as fertilizers and pesticides. Three-dimensional agriculture can make full use of land resources, improve the utilization rate of land resources, and effectively alleviate the contradiction between man and land and the contradiction between grain and cash crops, vegetables, fruit trees, and fodder crops competing for land.

Three-dimensional agriculture can greatly increase the output of agricultural products per unit area through intercropping, intercropping, mixed cropping and other modes, so as to effectively alleviate the contradiction between food supply and demand. Three-dimensional agriculture can alleviate the pressure of residual chemical fertilizers and pesticides on the soil environment and water environment, and reduce environmental pollution.

The main benefit of three-dimensional planting is to increase the planting area, improve the efficiency and increase income, and it will be much easier to manage, saving manpower and material resources, but not all plants are suitable for three-dimensional planting, such as most of the succulents are not suitable for three-dimensional planting, this method will block the sunlight and affect photosynthesis.

The introduction of three-dimensional implantation is as follows:

Three-dimensional planting refers to a planting method that makes full use of three-dimensional space, such as rice, ping, fish breeding combined with hand reed, broadly speaking, three-dimensional planting can also be understood as making full use of time, space and other planting conditions to achieve high-quality, high-yield, high-efficiency, energy-saving, environmental protection and confiscation of agricultural planting and breeding mode; A typical example is the traditional Chinese four-in-one courtyard agriculture model, which integrates biological components such as chickens, pigs, marshes, and vegetables into an ecological microcirculation system. Characteristics and functions of three-dimensional planting:

Intensive, that is, intensive management of land, reflecting the overall comprehensive benefits of technology, labor, material and capital; High efficiency, that is, to fully tap the potential of natural resources such as land, light energy, water source, heat, etc., and at the same time improve the utilization rate and utilization efficiency of artificial auxiliary energy; Sustainable, that is, to reduce the residue of harmful substances, improve the quality of the agricultural environment and ecological environment, enhance agricultural stamina, and continuously improve land productivity.

First, fine land preparation, apply sufficient base fertilizer before harvest and timely deep ploughing and stubble, shallow tillage raking near the white dew, 3000 kg of farmhouse fertilizer per mu, 30 kg of calcium phosphate, 15 kg of urea, level the ground before winter, build ridges and embankments, fill the winter water, early spring top rake rake, suppress and raise moisture two, with varieties, suitable for early sowing varieties require flax to mature early, compact plant shape, dwarf stalks, lodging resistance, good yield, the test proves that Ningya 11 is the most ideal, corn varieties are late maturing, dwarf stalks, low ears, lodging resistance, high yield, the test proves that Ningdan No. 8 or Zhangdan 1103 is more ideal, when sowing flax as early as possible, one grabs the whole seedling, the other avoids the frost in mid-May, early sowing of corn can avoid flax irrigation water caused by soil compaction and affect the emergence of seedlings, generally flax should be sown in early April, corn sown on April 25, 30.

Three-dimensional cultivation is also called vertical cultivation, which is to develop to space through columnar cultivation erected around without affecting the plane cultivation, and make full use of greenhouse space and solar energy to improve land utilization. Attention should be paid to the selection of cultivated vegetables, the advantages and the avoidance of weaknesses, as well as light and other conditions.

Three-dimensional cultivation is a three-dimensional planting technique. There are two things to keep in mind. Attention should be paid to the matching of varieties with short growth period and long growth period, and a reasonable field group structure should be arranged.

Three-dimensional planting refers to a planting (breeding) method that makes full use of three-dimensional space, and a simple example is the combination of "rice-ping-fish" planting and breeding. Broadly speaking, three-dimensional planting can also be understood as making full use of time, space and other aspects of planting (breeding) conditions to achieve high-quality, high-yield, high-efficiency, energy-saving, environmentally friendly agricultural planting and breeding mode.

Example: China's traditional "four-in-one" model of courtyard agriculture (e.g., integrating biological components such as chickens, pigs, marshes, and vegetables into an ecological microcirculation system).

Soilless culture is the most suitable for three-dimensional cultivation because of its light substrate and easy automation of the nutrient solution supply system. In recent years, there are four main forms of three-dimensional cultivation using soilless cultivation technology.

1 bag type: make the plastic film into a barrel shape, seal it tightly with a heat sealing machine, load it with rock wool, hang it in a greenhouse or greenhouse, and plant fruit and vegetable seedlings.

2. Hanging trough type: Hang wood cultivation troughs in the direction of the greenhouse space to plant crops.

3. Three-layer trough type: The three-layer wooden trough is erected in the air at a certain distance, and the nutrient solution flows against the water layer in the direction of the trough.

4. Column type: many columns are fixed, vegetables are cultivated around the columns, and the nutrient solution penetrates or flows from top to bottom. Wall cultivation is the use of specific cultivation equipment attached to the wall surface of the building, which not only does not affect the firmness of the wall, but also plays a certain role in protecting the wall.

To achieve the three-dimensional planting of plants, it effectively uses space, saves land, and achieves a larger output ratio per unit area. The sunlight of the plants cultivated on the wall is better than that of the ordinary flat cultivation, so the utilization rate of sunlight energy is higher. Vegetables suitable for wall cultivation are:

Lettuce, celery, strawberries, water spinach, beets, fungus, chives, leeks, rape, bitter herbs, etc.
