Three-dimensional soilless planting method of vegetable

Abstract

The invention discloses a spatial soilless vegetable planting method. The method is characterized by comprising the following steps: a. selecting two or more raw substrate materials such as biogas residue, furnace slag, grass carbon, decomposed fermentative crushed crop straw, decomposed fermentative crushed wood shavings, decomposed fermentative sawdust, decomposed fermentative lees and decomposed fermentative spent mushroom, and mixing the selected raw substrate materials to prepare a culture substrate; b. erecting a spatial cultivation groove in the existing facility space; c. installing a drip irrigation system, d. planting vegetable crops on a suitable upper layer and a suitable lower layer of the cultivation groove; and e. cultivation management. In the method, the vegetable cultivation is realized by carrying the culture substrate in a certain frame groove to artificially make an 'artificial land' in the limited facility space, the soilless vegetable cultivation is convenient as land cultivation and needs no nutrient solution, and the organic substrate and solid fertilizers provide nutrients necessary for growth and development of the vegetables, which can be accepted by vegetable growers, can improve utilization ratio of the facility by 50-200%, reduce cost by 30-60% and increase yield by 50-100%.

Description

Technical field: [0001] The invention relates to a three-dimensional soilless planting method for vegetables, belonging to the technical field of crop production methods. Background technique: [0002] With the growth of population and the relative reduction of land resources, people pay more and more attention to the research of soilless cultivation technology. Soilless cultivation is a high-tech agricultural technology, which has the characteristics of fertilizer saving, water saving, labor saving, high yield, high quality, no geographical restrictions, and clean and hygienic products. However, the one-time investment of traditional nutrient solution cultivation technology is relatively large, the operating cost is relatively high, the preparation of nutrient solution and planting management technology are difficult to master, and even some products (such as leafy vegetables) do not meet the standards of green food, so It has not been widely promoted.

AI Technical Summary

Problems solved by technology

The three-dimensional planting method of hydroponics and inorganic substrate cultivation has higher requirements on the education level and management technology of managers, a large one-time investment, and relatively high requirements on water quality. The nutrients needed for the growth of vegetables are completely provided by nutrient solutions. Production is not conducive to popularization and application, and it is currently difficult for vegetable farmers to accept it both technically and economically.
