The effect of de-fruiting on photosynthetic rate of leaves at different positions was studied by photosynthesis instrument. It was found that the effect of de-fruiting treatment on the leaves near the leaves was greater than that of the leaf leaves far away from the fruit, and after fruit removal, from the foundation to the new The photosynthetic rates of different leaves in the tip of the shoot are no longer a parabola change, but the trend of gradual increase indicates that the existence of the library has a great influence on photosynthesis of leaves at different positions.
The photosynthetic apparatus used to measure the change of photosynthetic rate of single leaves of fruit trees showed a "low-high-low" pattern. When the leaves were first developed, Pn was very low. With the growth of leaves, Pn increased. When the leaves were fully mature, the photosynthetic rate was the highest. After maintaining for a period of time, Pn gradually decreased with the aging of the leaves. At different parts of the shoot, the environmental conditions and physiological basis for leaf formation were different, and photosynthetic intensity also varied.
Under normal circumstances, the photosynthetic rate of the leaves of different shoots from the base to the top showed a parabolic change. The middle leaves were the highest and the leaves at both ends were gradually lower. At the end of the first rapid growth of the medium-to-long shoot, the photosynthetic rate of the 7th to 14th leaves of the middle part was the highest. The analysis of the photosynthesis instrument indicated that it was at the peak of physiological maturity, and the leaf photosynthetic rate below the 7th leaf was extended with the leaf opening time. The decline is the result of leaf aging.
Using the photosynthesis instrument to determine the different leaf ages, leaf positions, and sound field conditions, the results are not the same for all kinds of leaves. This also shows that the factors affecting photosynthesis of plants are diverse, in which the influence of light is the main Factors, illumination is one of the important factors of apricot productivity, different species and species, light compensation point and saturation point, light-pn curve are very different, even the same species, at different ages, different seasonal photosynthesis instrument The results of the measurements are different.

The granulator machine can make granules from wet powder materials or break down the dry lumpish material, which is widely used by the industries of pharmacy, chemical and foodstuff. By driving of mechanism, the cylinderis swinging to-and-fro to force the target material squeezed from sieveto make out granules or to smash it as granules. This granulation machine is made of stainless steel, in line with GMP standards.
