Special full-value nutrition liquid and organic substrate integral cultivating mode for eggplants

Abstract

The invention relates to a special full-value nutrition liquid and organic substrate integral cultivating mode for eggplants. Organic wastes, such as crop straws, waste slag after edible fungi cultivating, and feces of livestock, are used as raw material, and are subjected to harmless treatment to form an eggplant cultivating substrate. Water-soluble fertilizer is prepared into full-value nutrition liquid according to the fertilizer requiring rule of the eggplant, and the water and the nutrients are supplied to the root area of the eggplant in a water and fertilizer integral way. The cultivating mode for planting the eggplant has the advantages that safety is realized, the water and the labor are saved, the cost is low, the management is easy, the raw material of the substrate can be easily obtained, the utilization rate of the fertilizer is high, soil-borne diseases are avoided, and the like. The produced eggplant has the advantages that the yield is high, the fruit is fine, the taste is good, the nutrition ingredients are rich, the content of pesticide residues is low, the color is bright, the commodity rate is high, and the like. The cultivating mode disclosed by the invention is used for producing high-quality eggplant in the areas where the normal agricultural production cannot be carried out, such as heavy-salt alkaline lands, mountain lean lands and abandoned industrial and mining lands.

Description

(1) Technical field [0001] The invention is a supporting technology suitable for cultivating eggplants in greenhouses or plastic greenhouses. (2) Background technology [0002] Eggplant has strong adaptability, moisture resistance and heat resistance, and is relatively easy to cultivate. It is cultivated in most parts of the world due to its rich nutrition. China is the largest producer of eggplant. In 2002, the cultivated area of ​​eggplant in my country was 688,000 hm 2 , the total output is about 14.45 million tons, accounting for 54.5% of the world's total output. The economic benefits of protected cultivation of eggplant are good, but with the increase of planting years, the barriers to continuous cropping in many greenhouses become more and more obvious, and soil-borne diseases such as root-knot nematode, brown spot disease, and fusarium wilt are serious. In order to maintain high yields, vegetable farmers have to rely on extensive use of pesticides to control eggpl...

AI Technical Summary

Problems solved by technology

As a result of intensive planting of eggplants year after year, the ratio of nutrients in the soil is out of balance, and the utilization rate of fertilizers continues to decline. Vegetable farmers must rely on a large amount of fertilizer to maintain high yields of eggplants. Irrigation water enters groundwater or other water bodies, pollutes water sources, and causes environmental problems such as eutrophication of water bodies
