AI Technical Summary

Problems solved by technology

On the one hand, the preparation of nutrient solution and the management of the fertilizer supply system are technically difficult, and the cost of special fertilizers (such as calcium nitrate, potassium nitrate, magnesium sulfate and trace elements, etc.) for the preparation of nutrient solution is relatively high, making it difficult to be widely used. Producers master and use; the more fatal shortcoming is that the content of nitrate nitrogen in the nutrient solution accounts for more than 90% of the total nitrogen, resulting in excessively high nitrate content in the organs of vegetable products, which does not meet the green food standard. All these factors are Limit the further popularization and application of nutrient solution soilless culture technology

specific Embodiment approach

[0011] The invention belongs to the national "Tenth Five-Year Plan" research project - comprehensive management and high-efficiency utilization model and technology research on saline-alkali land in the west of Songnen Plain (2001 BA 508 B05). In 2005 and 2006, a demonstration of the technology of the present invention was carried out in Jianguo Village, Xinfa Town, Daoli District, Harbin City (Harbin Xinfa Pollution-Free Vegetable Co., Ltd.), a key green and pollution-free vegetable production base in the country and Heilongjiang Province. The specific implementation method is:

[0012] The effective area of ​​the greenhouse is 667m 2 , set up a soilless cultivation system, including cultivation tanks, drip irrigation facilities, etc.

[0013] 1. Cultivation trough: The greenhouse faces east-west, leaving 80cm in the middle for the aisle, and 30cm for the north and south sides respectively. The two sides of the aisle are built with bricks to form a north-south cultivation tr...

Abstract

A method for manuring green vegetable straw substrate soilless cultivation is efficient, simple and ecological and economical. It has no chemical fertilizers and pesticides and has better vegetable quality, it utilizes disinfectant organic fertilizer to offer vegetable needed nutrients and improves tomato yield in greenhouse above 20% and 40%.

Description

technical field [0001] The invention belongs to the technical field of agricultural production. The invention is a fertilization method for the soilless cultivation of green vegetable stalks in a protected area. Background technique [0002] Heilongjiang Province has taken "green food development" as an important development strategy for building an ecologically strong province. At present, the province's green food industry has major indicators such as product certification, monitoring area, total production, market development, key processing enterprises, and sales. Ranked first among all provinces in the country. However, with the rapid increase of vegetable production area, green vegetable production is facing severe challenges. Generally, after 3-4 years of use in vegetable production fields, vegetable continuous cropping obstacles such as aggravation of vegetable diseases and insect pests, decline in quality and yield will appear to varying degrees. In order to maint...
