Embodiment Construction

[0041] The specific content of the method provided by the invention is as follows, see figure 1 :

[0042] 1. Fix the sample, plant a certain number of plants in the greenhouse field (tomato seedlings are cultivated in the greenhouse) and cultivate them with high border ridges, the planting spacing is 40cm, the maximum row spacing is 80cm, and the planting density is 4.17 plants m -2 . In the greenhouse, 20 plants with consistent growth were selected and marked (to prevent abnormal growth or death of samples during the growth period).

[0043] 2. Collect data. From the day of planting, observe and record the number of leaves and spikes on 3 to 5 sample plants for the first time. Leaves with a length of 2 cm or more must be recorded. After that, every 7 to 10 The observation and recording of the sample plants were carried out every day until the tenth ear fruit from bottom to top matured or the tomato plants died;

[0044] 3. Calculate the maximum occurrence rate of nodes: n...

Abstract

The invention provides a method for controlling the growth of tomatoes by establishing a sunlight greenhouse long-season cultivated tomato plant leaf number model. Due to the technical scheme, the method comprises the following steps of: fixing samples; acquiring data; establishing a tomato leaf formation simulation model; and controlling growth management according to the simulation model. The method has the advantages of determining a corresponding relationship between the senescence of tomato leaves and a greenhouse environment and optimizing the regulation and control on the greenhouse environment such as temperature and humidity by using environmental equipment so as to enable the tomatoes in the sunlight greenhouse to grow and develop in a proper environment and realize high-yield and high-quality cultivation.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural production, and particularly relates to a method for establishing a leaf number model for long-season cultivation of tomato plants in a solar greenhouse for controlling tomato growth. Background technique [0002] Greenhouse is a comprehensive system integrating structure, electromechanical, biology and environment. The key point of greenhouse environment control is to coordinately control the microclimate of crop growth, so that the crops can grow and reproduce normally, and obtain high yield and high quality. The basic requirements of crops on the environment are the basis of all environmental control system design. Since the response of crops to environmental conditions is very complex, the maximum benefit of production in the greenhouse can only be fully realized with the help of complex environmental control devices and control methods. That is to say, the so-called "composite" ...
