In this study, the sowing dates of different species and ecological sites were used to quantitatively analyze the effects of radiation and temperature on the distribution of sweet pepper, and the relationship between the growth of fruit dry matter quality and the increase of fresh quality. The sweetness index was calculated using Based on the model of pepper dry matter distribution, the dry matter production model driven by photosynthesis and the quantitative distribution of the dry matter distribution of sweet peppers based on the heat of fusion and the relationship between the growth of fruit dry matter and the growth of fresh quality were combined to establish the greenhouse pepper growth and yield prediction. The model provides a theoretical basis for the accurate management of the light temperature in the production of greenhouse sweet peppers in China.
After colonization of bell peppers, destructive sampling was performed every 7 to 10 days. Each time 3 healthy and uniform peppers (10 seedlings) were grown and sweet peppers were measured. Leaf length, leaf width, and leaf area of ​​all leaves were measured and then divided. Roots, stems, leaves, and fruits were weighed to measure the fresh quality of the plants, then dried in an oven at 105° C. for 20 minutes, and dried at 80° C. to a constant mass. The dry mass was then weighed. The leaves, branches and harvested fruits of each pruning were weighed separately for fresh and dry quality. Fifteen strains of each strain were selected for planting, and the fresh fruit quality of each harvest was recorded.
The application of greenhouse housekeepers The solar radiation measurement point in the solar greenhouse is in the center of the greenhouse. In fact, the solar radiation distribution in the solar greenhouse is not uniform, and the solar radiation in the center of the greenhouse is higher than the average value of the solar greenhouse, which leads to a slightly higher prediction of the total dry matter quality of the sweet pepper than the measured results. To improve the prediction accuracy of the model on the dry matter production of sweet pepper in solar greenhouse, it is necessary to further integrate this model with the solar greenhouse light distribution model in the future. This model has a greater error in predicting the quality and yield of bell pepper. The main reason is that the model does not consider the impact of fruit drop and fruit on the dry quality and yield of the fruit. Therefore, how to consider the impact of fruit drop and fruit on the dry quality and yield of fruits is the key issue to be solved in the future to improve and improve the accuracy of model prediction.
Application of Greenhouse Housekeeper in Sweet Pepper Planting in Greenhouse
Greenhouse cultivation is very important for the control of the conditions of the greenhouse environment. For the simulation model of greenhouse greenhouse sweet pepper growth and yield prediction in the short-season cultivation conditions in China, there are still few reports. Under certain conditions of cultivation, temperature and radiation are the two most important environmental factors that affect crop growth. Greenhouse stewards can generally be used to manage the greenhouse environment.
