Method for cultivating vegetables in organic soil

Abstract

A method for cultivating vegetables in organic soil includes such steps as preparing the organic soil from the fermented leftover of agricultural crops, fermented organic fertilizer and clean soil, digging the ditches, spreading plastic film on the bottom of each ditch, filling said organic soil, covering it by a layer of cleaning soil, laying a drop irrigation system, irrigating, covering by a plastic film for 5-7 days, cooling, and planting vegetables.

Description

technical field [0001] The invention relates to a cultivation method, in particular to an organic soil cultivation method for facility vegetables. Background technique [0002] Facility vegetables refer to vegetables grown in covered protection devices such as greenhouses or greenhouses. At present, their cultivation mainly includes traditional soil cultivation, soilless cultivation of peat, vermiculite and other substrates, soilless cultivation of rock wool nutrient solution and organic ecological soilless cultivation. . They have the following defects respectively: [0003] 1. The traditional soil cultivation has great differences in the fertility of different plots, and the standardization is poor. Traditional soil cultivation farmers often use large amounts of water and fertilizers for facility vegetable production, and use a large amount of organic fertilizers and chemical fertilizers. The quality declines, and at the same time, it is easy to cause groundwater polluti...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional soil cultivation has great differences in the fertility of different plots, and the standardization is poor. Traditional soil cultivation farmers often use large amounts of water and fertilizers for facility vegetable production, and use a large amount of organic fertilizers and chemical fertilizers. The quality declines, and at the same time, it is easy to cause groundwater pollution, soil salinization and compaction, and frequent occurrence of soil-borne diseases, making it difficult to use

[0004] 2. Soilless cultivation of peat, vermiculite and other substrates: Since peat and vermiculite are natural raw materials, the regeneration cycle is long, and the investment cost of transportation and other substrates is high. Except for seedlings or modern greenhouses, it is not suitable for raw materials due to limited sources. Large-scale promotion

[0005] 3. Soilless cultivation of rock wool nutrient solution: it is widely used in foreign countries, the production cost is high (10,000 yuan / mu), and the operating cost of nutrient solution is also high, so the domestic application is less, and the waste after rock wool cultivation is difficult to deal with , Wasted nutrient solution will also cause environmental pollution, and future development will be restricted

[0006] 4. Organic ecological soilless cultivation: using slag, peat, river sand, sawdust, mushroom residue, etc. High, limited sources of raw materials, not suitable for industrialized production and large-scale promotion in major vegetable production areas, and the return of organic ecological soilless culture substrates to the field may cause secondary pollution, which is restricted in fertile soil farming areas
