Method for organic cultivation of yam by means of greenhouse facilities

Abstract

The invention discloses a method for organic cultivation of yam by means of greenhouse facilities. The method includes the steps of arrangement of cultivation facilities, preparation of cultivation boxes, preparation of cultivation racks, preparation of cultivation mediums, seed soaking and disinfection, seed placement in the cultivation boxes, placement of the cultivation boxes, water and fertilizer management, disease and pest control, harvesting and processing, and the like. Compared with an existing yam cultivation method, the method for organic cultivation of the yam by means of the greenhouse facilities can be adopted to comprehensively solve the problems existing in yam cultivation at present; through the combined use of the cultivation boxes and the cultivation racks, the yam planting density is greatly increased, and the economic benefits of the yam per unit area are increased; in addition, in the method for organic cultivation of the yam by means of the greenhouse facilities,the cultivation mediums are used instead of soil, and chemical fertilizers and chemical pesticides are not used in the cultivation process, so that the yam grows in a pure and pollution-free environment and accordingly has better quality. The method for organic cultivation of the yam by means of the greenhouse facilities can be adopted to obtain the yam which meets the certification requirementsof organic yam, has the advantages of being capable of providing convenience for harvesting and realizing good quality and high yield of the yam, is conducive to scaled and large-scale cultivation ofthe organic yam, and has high social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to an organic cultivation method for yam greenhouse facilities. Background technique [0002] With the improvement of people's living standards, the demand for healthy and nutritious organic food is also increasing. According to the statistics of the World Food and Agriculture Organization, people's demand for organic food is increasing by 5% every year, and organic yam is a health-care vegetable with both food and medicine. , with better economic benefits and market prospects. [0003] However, the cultivation of organic yam must be certified, and the certification requirements are as follows: soil, water, and air are free from pollution, and no chemical fertilizers and chemical pesticides are used. However, due to the fact that the land in our country is generally polluted by groundwater sources, and the yam itself has a high requirement for the depth...

AI Technical Summary

Problems solved by technology

However, due to the fact that the land in our country is generally polluted by groundwater sources, and the yam itself has a high requirement for the depth of the soil layer (more than 1 meter), it is difficult to select a site to meet the requirements of soil, water and air pollution at the same time; Secondly, without the application of chemical fertilizers, it is easy to cause insufficient nutrient supply, without the application of chemical pesticides, serious pests and diseases, and difficulty in weed removal, which will easily lead to a decrease in the organic production of yams; The cycle is long, the labor intensity is high, and the labor cost is high.

[0004] To sum up, in the process of organic cultivation of Chinese yam, there are the following problems: high requirements on the depth of the soil layer, difficult selection of land, difficulty in harvesting, labor-intensive and time-consuming, the soil, water source, and air must also be free from pollution, and cannot be harvested. The application of chemical fertilizers and chemical pesticides has led to difficulties in the cultivation of organic yams and insufficient production, resulting in low yields, poor commerciality, and high prices of organic yams, which cannot meet the needs of consumers. In addition, the quality of yams cultivated in the field cannot be visually monitored. There will also be problems of poor consumer trust in product quality

The existence of these problems has caused the organic production of yam to be unable to scale, the supply of organic products is insufficient, and the market demand cannot be met, the input-output ratio is small, and the product price is too high (3 to 10 times that of ordinary yam), which exceeds the price expectations of potential consumers. The current market situation where consumers have poor trust in product quality
