Abstract: The effects of light intensity and salinity on algal growth were investigated under three light intensities (3000 lx, 6000 lx and 12000 lx) and seven salinity levels (10, 15, 20, 25, 30, 35 and 40) in a disposable incubator. The results showed that light intensity had a significant effect Read More

Light intensity plays an important role in plant growth and morphological structure. Light has direct and indirect effects on plant growth. The direct effect refers to the role of light on plant morphogenesis, as far as the plant growth process itself, it does not need light. Plants can grow in the Read More

Tomatoes, peppers, eggplants, cucumbers and other fruit and vegetable seeds germination is slow, are required to germinate, now the germination technology is introduced as follows:　　First, the selection of seeds: be sure to choose good seed full, consistent size, high purity seeds, to remove the soi Read More

1, constant temperature and humidity test chamber low temperature can not reach the test indicators, then you have to observe the temperature change, is the temperature drop very slowly, or the temperature to a certain value after the temperature has a tendency to rise, the former will have to check Read More

face of the equipment should be often sassafras, in order to keep clean and increase the transparency of the glass. Please do not use acid, alkali or other corrosive solutions to sassafras external surface.　　4. equipment downtime should be done when not in use to drive moisture treatment, the specif Read More

1, the transmission preservation method: some microorganisms when encountering freezing or drying and other treatments, will soon die, so in this case, can only resort to the transmission culture preservation method. Succession culture is to regularly transfer strains, culture and then save, it is t Read More

Before the world of humidity detection and temperature detection compared to the level of components lagged behind a lot, this is an indisputable fact, whether it is capacitive sensors or resistive sensors, the accuracy can be ± 2%, is already very impressive, and the price is quite expensive; doubl Read More

【Abstract】Objective: To study the effects of seed soaking with different concentrations of two growth regulators, Good Fresh Harvest and Flower DuoLe, on the germination and growth of Eustoma seeds. METHODS: Using double-layer filter paper culture method and indoor potting method, the soaked seeds w Read More

First, the significance of seed germination seeds through germination can not only lift the dormancy, but also can make the young shoots in the right time out of the ground, out of the ground neatly, and to improve the germination rate of Yang nursery at the same time can also enhance the resistance Read More

Nitrogen is one of the most important nutrients in the growth process of flue-cured tobacco. Through low-temperature cultivation and research in a biochemical incubator, it was found that more than 60% of the nitrogen nutrients absorbed by flue-cured tobacco come from the soil, and fertilizer nitrog Read More

Operational details of coliform group determination Coliform group refers to a class of Gram-negative non-spore-forming bacilli that can ferment lactose, produce acid and gas, and are aerobic and facultatively anaerobic. The bacteria mainly come from human and animal feces, so as a fecal contaminati Read More

1. The biochemical incubator must be placed in a sun-proof, ventilated and dry place, with the distance between the equipment and the wall not less than 10cm.2. The biochemical incubator should be installed on a three-pin power socket with reliable grounding to ensure normal operation and personal s Read More
