Intelligent artificial climate box changes the flower in the low temperature setting
In the low temperature environment, many plants will be affected without normal growth and development, and certain changes will occur at different temperatures. Simulation of low-temperature process through intelligent artificial climate box Three kinds of flowers, such as roses and chrysanthemum (two varieties), which are typical in winter agricultural production, were subjected to low-temperature treatment to continuously observe the morphology and germination growth of flowers at different temperatures during different periods of low temperature. Changes, the preliminary analysis of the above 3 flowers in the case of their ability to resist cold in their growth, but also to provide guidance and reference for cold protection services. Hydraulic Core Drilling Rigs / Geotechnical Exploration Small Water Well Drilling Rig Machine
Bore hole water well drilling machine is a kind of widely used portable drill machine. Water well drilling rig is suitable for drilling water well, geological survey, geological core drilling, small grouting holes, blasting holes of railway, water conservancy, bridges, dam foundation and other buildings. According to different strata, it drills by choosing different bits, such as, diamond composite films and alloy.

Potted rose, early flower chrysanthemum and late flower chrysanthemums were used in 3 different varieties. The setting of meteorological parameters of the intelligent artificial climate box, temperature parameters: daily average temperature 5.5 °C, observation and recording after relevant pretreatment.
Rose: In the low-temperature weather within 5 days, the buds and leaves of roses grow normally; the low-temperature weather of 6 to 7 days has a slight effect on some buds and leaves of roses; the low temperature weather has a more obvious effect on the flowering period of roses. The effect of roses on the number of days when the temperature is low is longer and the flowering period is more pronounced.
Chrysanthemum-Huang Xinhong (early flower type): Under the cold weather of intelligent artificial climate box in 7 days, the flower buds and leaves of chrysanthemum in early flowering varieties grew normally, and their development process was not significantly affected by cold weather and cold weather.
Chrysanthemum - Jade Hydrangea (later flower type): Under low temperature conditions within 7 days, the flower buds and leaves of chrysanthemums of late-flowering varieties grow normally. Cold weather affected the flowering period of chrysanthemum species with late flowering type. The number of days with low temperature increased by 1d, the flowering period basically delayed by 1d.
The cold weather in the intelligent artificial climate box for 7 days does not produce significant cold damage to the growth of roses and chrysanthemums, but its growth and development process has different degrees of delay effect depending on the variety. There was a positive correlation between the number of delayed flowering days and the number of low temperature days experienced in rose and late flowering chrysanthemum varieties. Early and late flowering chrysanthemum varieties will not be affected by low temperatures in the morning and evening, and are mainly controlled by the length of sunshine, which is consistent with the actual production.
In addition, in order to test the effect of the study is more obvious, for some other light, humidity and other parameters strictly consistent and constant factors, which will help the smooth progress of the study, by setting a different temperature in a certain period of time to study the above Changes in the shape of the flowers. In addition to the different settings and comparisons of the intelligent artificial climate chamber, it is also possible to observe the subsequent growth of the treated plants and the control plants at the outdoor test site, and the appearance growth characteristics of the treated plants varied in varying degrees.
1. It improves drilling efficiency and reduces labor intensity with hydraulic automatic feeding mechanism
2. It can be achieved without stopping to change rods, easy to operate, safe and reliable with ball clip holding mechanism or hydraulic chuck.
3. It has hole bottom pressure gauge to be easy to master the situation in the hole
4.It also has advantage of compact structure,concentrated handle, small footprint, light weight, strong decomposition, easy to move. It can be operated in plains and mountain areas.
