Energy-saving environment-friendly vegetable planting method

Abstract

The energy-saving environment-friendly vegetable planting method mainly comprises the following steps: focusing sunlight, guiding sunlight to places without enough sunlight illumination via optical fibers, planting, and providing demanded nutrition to plants by utilizing waste product, organic household refuse and sanitary wastewater. Therefore, the purposes of protecting the environment, saving the energy and expanding the planting space are achieved.

Description

technical field [0001] The technical field of energy-saving and environmentally friendly vegetable planting belongs to the field of optics and cultivation. It mainly focuses the sunlight, guides the light to places where the sun is not enough through optical fibers, and plants it, and uses human excrement, organic domestic garbage and domestic wastewater. Provide the nutrients needed by plants to achieve the purpose of environmental protection, energy saving and expansion of planting space. Background technique [0002] Now our country is carrying out large-scale urban construction, the land is being built on a large scale, the land is becoming less and less, and the water pollution is extremely terrible, fresh water resources are becoming increasingly scarce, human excrement, organic domestic waste and domestic wastewater are not being well utilized. , and cause environmental pollution, excessive use of chemical fertilizers will cause land bleaching, and excessive use of pe...

Problems solved by technology

[0002]Now our country is carrying out large-scale urban construction, the land is being built on a large scale, the land is becoming less and less, and the water pollution is extremely terrible, fresh water resources are becoming increasingly scarce, and the human body Excreta, organic domestic waste and domestic wastewater are not well utilized, and cause environmental pollution. Excessive use of chemical fertilizers causes land bleaching, and excessive use of pesticides causes vegetable residues to affect human health. The current planting methods are general There are the following methods, 1. The traditional planting method has the advantages of directly planting in the ground, large space, sufficient sunlight, and low cost. The disadvantages are that it is affected by seasonal changes, insect pests, geographical environment, and irrigation. And the impact of fertilization, because the use of organic fertilizers is troublesome, more direct use of chemical fertilizers will cause land whitening, and excessive use of pesticides will cause excessive vegetable residues and land poisoning, so they cannot be planted in cities or residential areas.

2. Vegetable greenhouse planting, the use of vegetable greenhouse planting inherits the advantages of traditional planting methods, and the biggest advantage is to advance the market time of vegetables and reduce pest damage, which greatly improves the income of growers, but the disadvantage is that it increases investment, or Affected by seasonal changes, insect pests, geographical environment, irrigation and fertilization, it cannot be planted in cities or residential areas

3. The advantage of vegetable factories is that they are not affected by seasonal changes, insect pests, geographical environment, irrigation and fertilization, and can be planted in multiple layers, greatly reducing space, and it is soilless cultivation, but it The fatal disadvantage is that the investment is huge and the cultivation cost is expensive

4. Household soilless cultivation, its advantages are that there are no pesticide residues, and the food is fresh. The disadvantage is that it takes up space in the home, the varieties planted are limited, there is no nutrition at all, and the cost is expensive

5. Planting on the roof. The advantage of planting on the roof is that the space on the roof is effectively used and the sunlight is abundant, but the disadvantage is that some roofs are covered with tiles and cannot be used. If the roof is soaked in water, it will be harmful to the house. It has a great impact on the lifespan of the house, the gain outweighs the loss, and the cost of transporting water, nutrients, and various other things to the roof is also very high

Now in cities, towns and villages, people's excrement and kitchen organic matter are directly discharged into the river through the sewage pipe, which not only wastes the nutrients these plants need, but also pollutes the river. Through the pond dug, it penetrates directly into the ground, which not only wastes the nutrients these plants need, but also pollutes the groundwater.
