Problems solved by technology

However, due to factors such as facility coverage, shading of the skeleton structure, rainy and snowy weather in winter and spring, the crops in the facility often grow in a weak light environment
Due to insufficient light, excessive accumulation of nitrate in leafy vegetables, eating this kind of vegetables is extremely harmful to human health

Embodiment 1

[0019] Greenhouse lettuce (Lactuca sativa L.) (variety: Italian bolting-resistant lettuce) 30 days after the seedlings were taken out. The rapid light response curve of lettuce leaves was measured with PAM-2000 modulated chlorophyll fluorescence instrument. According to the response curve of apparent electron transfer rate to photosynthetically active radiation ( figure 1 ) Follow the steps below to determine a reasonable light dose.

[0020] Step 1 calculates the actual photosynthetic electron transfer rate. Find out under low photosynthetically active radiation, the linear part in the curve of apparent electron transfer rate and photosynthetically active radiation, utilize statistical software to obtain the linear equation Y=aX of this part (a is a constant, represents apparent electron transfer rate and photosynthetic active radiation initial slope of the effective radiation curve). The equation is:

Abstract

The invention discloses a determining method of reasonable illuminating dose of a facility vegetable, which belongs to the technical field of facility growth. The reasonable illuminating dose of the facility vegetable is determined according to the following steps: taking the facility vegetable in the peak of a growing season; measuring a quick light response curve of vegetable leaves by a chlorophyll luminoscope and determining the reasonable illuminating dose of the facility vegetable according to a response curve of the transmission rate of apparent electrons to photosynthetic effective radiation in the quick light response curve of the vegetable leaves. By using the reasonable illuminating dose of the facility vegetable determined by the method, higher yield and lower nitrate accumulation level are ensured and energy sources are saved to the maximum, thereby the unification of high yield, good quality and low consumption is realized. The method has the advantages of high efficiencyand speed, convenient operation and wide application range and can be used for facility growth vegetables and facility growth medicaments.

Description

technical field [0001] The invention belongs to the technical field of facility cultivation, and in particular relates to a method for determining a reasonable light dose of facility vegetables. Background technique [0002] At present, protected cultivation of vegetables has been widely carried out all over the world. As of 2003, the domestic protected horticultural cultivation area exceeded 1.4 million hectares, ranking first in the world. According to experts' forecasts, by 2010 the national horticultural facility area will reach about 2.5 million hectares. Vegetable protected cultivation has become one of the main means of vegetable production. However, due to factors such as facility coverage, shading of the skeleton structure, rainy and snowy weather in winter and spring, the crops in the facility often grow in a weak light environment. Due to insufficient light, excessive accumulation of nitrate in leafy vegetables, eating this kind of vegetables is extremely harmfu...
