Agricultural Environment Monitoring Station Monitoring the Growth Environment of Facilities Strawberry

August 14, 2019

With the 2012 World Strawberry Conference held in Beijing and the development of modern urban agriculture in Beijing and the deepening of structural adjustment, the strawberry planting area for facilities that are suitable for market demand continues to expand, and strawberry picking in winter and spring has become a major highlight of agricultural development in Beijing's suburbs. At present, the cultivation method of strawberry facilities in Beijing is mainly in greenhouse soil cultivation. The cultivation environment of the facility is relatively closed and fixed. The environment temperature and humidity conditions are usually conducive to the spread of strawberry pests and diseases. In the absence of scientific guidance, farmers are more likely to abuse pesticides in strawberry production. Therefore, it is very necessary to pay attention to the quality and safety of strawberries and understand their hidden dangers. The agricultural environmental monitoring station can effectively monitor the environment in the greenhouse and provide an effective reference for the growth and control environment of strawberries.

Take a combination of data collection and field surveys. Before the on-site investigation, the questionnaire was designed based on the characteristics of strawberry production and cultivation. The questionnaire was based on the sampled plots. The content mainly included soil disinfection methods, seed varieties and sources, fertilizer application, pest occurrence and control, and use of plant growth regulators. , storage and preservation.

In the survey of agricultural environmental monitoring stations, it was found that organic fertilizers are the main organic fertilizers used in strawberry cultivation, and organic fertilizers account for a small proportion of organic fertilizers. Most of them are organic fertilizers produced by farmers. The application of organic fertilizer may be a hidden danger of heavy metals, and if not completely decomposed organic fertilizer may also bring potential pathogens and parasites harm; In addition, the use of phosphate fertilizer has varying degrees of use, excessive application of phosphate fertilizer will not only affect the strawberry on zinc The absorption of iron and iron may also contain a large amount of harmful heavy metals such as chromium, cadmium, and lead. As a picking fruit for fresh food, strawberries have hidden dangers of pathogenic microorganisms during instant picking or storage and transportation. In this study, pathogenic microorganisms were detected in only 18 strawberry samples during the March-April period. The number of samples was small and the representativeness was insufficient. Therefore, on the basis of studies on the control of residues of pesticides and plant growth regulators, follow-up studies should be conducted on the risk assessment and control of factors such as strawberry pathogenic microorganisms and heavy metals, and the effects of various inputs on their quality, in order to provide comprehensive protection for the quality and safety of strawberries. support.
