At present, the pears of most farmers have been harvested and the pear orchards are being cleared. In order to produce high quality and high quality pear trees in the coming year, the pear farmers in various places should immediately start applying the harvested fruit fertilizer after the clearing of the pear garden. The fruit fertilizer is the base fertilizer (also called reducing fertilizer). The time and quantity of base fertilizer application is related to the yield and quality of pears in the coming year. This is because, first, the base fertilizer is the main fertilizer of pear trees. In the pear production cycle, the base fertilizer accounts for the largest proportion of total fertilizer demand; From September to November, the roots of pear trees enter the second peak of growth. At this time, fertilization is beneficial to the rapid decomposition of fertilizers, and it is beneficial to the new roots to absorb and store nutrients. Third, the long time of fertilizer absorption can increase the cell fluid. Concentration, improve the ability to resist wintering; Fourth, the fertilizer effect of the base fertilizer is good, can be effectively played in the nutrient critical period of pear trees (April to May), and the utilization rate is high; Fifth, the nutrient absorption is early, which can increase the fullness of flower buds. Improve the quality of flower buds and the rate of fruit set, and increase the sugar content; sixthly, it can avoid the spring shoots caused by the spring base fertilizer, causing freezing damage.
In order to apply the basic fertilizer for the pear tree, the following points should be taken in the technical aspects.
First, choose the best time for fertilization. The base fertilizer can be applied after the pears are harvested until the spring buds are germinated, but the fertilization is the best period in autumn, and the fertilization is recommended when the sensation is good in September and November.
Second, the selection of high quality organic fertilizer. The application of organic fertilizer can improve the soil, improve the soil fertility, and reduce the inorganic fertilizer to be fixed by the soil and improve the fertilization capacity. Generally, each pear tree is fertilized with soil or poultry and livestock manure of about 50 kg, with 1 kg of phosphate fertilizer, 1 kg of nitrogen fertilizer, or 5 to 15 kg of different types of bio-organic compound fertilizer and high-energy compound fertilizer. The base fertilizer should account for 60% to 70% of the annual fertilizer use of pear trees.
Third, flexible use of fertilization methods. The application method of the base fertilizer is flexibly applied due to the age of the tree and the local habits. First, the pear trees with new fruit harvesting can be fertilized by the ring; the second is to use the ditch fertilization according to the direction of the root system; the third is to open the ditch strip between the rows of pear trees; The fourth is to dig a deep hole. These methods are applied alternately between years. In order to reduce the waste of fertilizer, one must apply deep, combined with autumn and winter to deepen the application of 30 ~ 50 cm; Second, in the case of drought, timely irrigation, to achieve water and fertilizer.

The series activated carbon is mainly used for the purification of drinking water, deep degree treatment of industrial of super purified water. The organic substances, which are harmful to human health and environment, can be effectively removed.
l Technical Properties of Our Product
In recent years, Huahui Company aims at developing the deeply purify craft of domestic drinking water and property of water quality. Our products have the technological property as follows:
l Low ash content
Having this property is mainly due to choose `Taixi` anthracite as raw material of coal based activated carbon, and it`s the foundation that makes Ningxia activated carbon to exist. It possible to make activated carbon applied in purification water rejuvenate more times.
l Low floating rate
Through manufacturing craft of milling into powder, mixture and extruding, we achieve the homogenization of raw coal, break the different property of microcrystalline structure when raw coal is in natural mineralization. Then through stairs-shaped preoxidation carbonization craft, we get the excellent semi-finished products with high hardness. and thus ensured the stability of finished products and decrease the floating rate as well. This property meets the requirement on floating rate of activated carbon for water purification, and it depends on manufacturing craft of Ningxia activated carbon.
l High hardness
The main purpose of carbonization is to separate out the light
fraction from molding material and to form into primary pore organization, also
to provide channel of further reaction for activation craft. In the meantime,
to activate the semi finished carbonized materia with high hardness ensures the
high hardness of finished products.
