Study Of Greenhouse Pepper Water Requirement Information

The greenhouse has its own relatively independent of climate and environment and there are great different between the traditional field.This trial was conducted to study the pepper water demand information in greenhouse in songyuan。In order to collect relevant data in the greenhouse pepper water demand.The test sample selection blossom fruiting period Cayenne,Inside of the meteorological.Greenhouse has its own relatively independent of climate and environment,and there are great differences between the traditional field.This trial was conducted to study the pepper water demand information in Greenhouse in songyuan。In order to collect relevant data in the greenhouse pepper water demand.The test sample selection blossom fruiting period Cayenne,Inside of the meteorological factors and pepper the greenhouse(temperature,humidity) monitoring,To explore the relationship between these factors and the effect of crop water requirement is an important indicator of between leaf water potential,And the transpiration efficiency test analysis,Found that the light is too strong will inhibit transpiration, thereby inhibiting water demand of pepper, thus preliminary judgment rules of the environmental factors on the growth and water requirement of pepper, and how to reasonably establish the regulation of light in greenhouse, set in the greenhouse air temperature and humidity and light intensity on the efficient use of water is of great help。Have some understanding of the regularity of water requirement of pepper, the experiment on how to determine the pepper in a dry state for further study.According to the research on the theory of other scholars, using leaf temperature to judge whether the pepper in water deficit condition index.When using sufficient water supply and water is in short supply in two cases,leaf temperature have obvious difference. Thus verified between leaf temperature and water supply connection. Water deficit conditions and factors of atmospheric saturation pressure difference, the net solar radiation etc. andpepper judgment established a certain relationship. In order to achieve the status of water supply of hot pepper is a scientific understanding of.Through the implementation of the above experiment, preliminary analysis can realize the planting of greenhouse pepper water demand and water deficit, but also can provide some reference on the whole greenhouse planting the crop water demand.
