Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in combination with specific embodiments.

[0022] The management method of environmental factors in the industrial production process of hydroponic lettuce, the specific measures are as follows:

[0023] 1) Light and temperature management, set up a sunshade net in the greenhouse, because lettuce seeds are light-requiring seeds and need light when they germinate, so when sowing, the seeds are directly sown on the surface of the seedling substrate one by one to meet the light requirements. However, in order to avoid the damage caused by too strong light to the seeds, the temperature in the greenhouse must be controlled at 10~25°C. Specifically, when the light intensity is greater than 1500Lux or the temperature in the greenhouse is greater than 30°C, close the sunshade net; An air conditioner is installed to ventilate and cool down the air in the greenhouse in a timely manner according to t...

Abstract

The invention discloses a management method for environmental factors in the industrialized hydroponic lettuce production process.The management method comprises the following measures of 1 light and temperature management; 2 water management; 3 nutrient solution management; 4 disease management.According to the management method, an optimal growth environment is supplied to growth of lettuces, the yield, quality and safety of the lettuces are guaranteed, and the lettuces cultured by adopting the management method are little in disease and pest damage, not prone to root rot, low in production cost, high in yield, good in quality and commodity and high in safety.

Description

technical field [0001] The invention relates to the technical field of hydroponic planting of facility vegetables, in particular to a method for managing environmental factors in the industrial production process of hydroponic lettuce. Background technique [0002] The scientific name of lettuce is leaf lettuce, which is native to the Mediterranean coast and is divided into three types: long-leaf lettuce, wrinkled-leaf lettuce and head lettuce. Its nutritional value is high, and its vitamin V A , V A1 , V B2 The content of calcium and iron is higher than that of ordinary melons and fruits. The leaves are crisp, tender and refreshing. They can be eaten raw, cold or used as salad cold dishes. They are listed as the three major vegetables for greenhouse soilless cultivation along with tomatoes and cucumbers. Because of its small plant shape and short growth period, lettuce is suitable for hydroponics, and it is the crop with the largest area of ​​hydroponic vegetables at hom...
