Usage:Widely used as a kind of slow
release green fertilizer with the efficiency of pesticide,
germcide, weedicide, raising ground/earth temperature, adjusting
alkaline and acidity in the soil. Applying this fertilizer
can speed the roots, stems and straws of the plants left
in the field to become thoroughly decomposed and change
into soil organic matter, and meanwhile this fertilizer
can inhibit nitrate reaction. It has dual of pesticide and
fertilizer. It flies up with no dust and with good fluidity
when using it, No polluting environment.
Package, Storage and Transportation:In
net 20kgs plastic woven bags with PE inner liner. Other
packages are available in accordance with the customer's
requirements. Stored in cool, dry and ventilated warehouse
and prevent from moisture when transporting, loading and
unloading.

Multifunctional
environment-friendly fertilizer--calcium cyanamide granular
Brief Introduction:
| Calcium Cyanamide is a kind of long-effective
fertilizer and can supply plants with necessary nitrogen,
calcium. It can inhibit the nitrification and upgrade
the efficacy of nitrogen. It also can speed up the decomposition
of straws and poultry manure and increase the efficacy
of composting. Most importantly it can control pest
and weeds in the field and adjust acid-base of soils
to improve the quality of soils. |
The results of application:
 Darong
is the first producer of calcium cyanamide. Since 1998,
it has worked with some Chinese universities like Zhejiang
agricultural university, South China agricultural university
and Hunan agricultural university to make application
research and experiments on calcium cyanamide. The results
showed 6.56% in the yield increase of cauliflower; 5-7
days reduction in its growth periods; 46% in the yield
increase of cowpea, 11.40% of chili and 13.32% respectively.
In July 1999, Darong started to work with agrotechnical
station to make experiments on application of calcium
cyanamide to many vegetables including cabbages, strawberry,
and eggplants, tomatoes, which present the representatives
of vegetables and are planted a lot. The results showed
the yield increase was significant, 14.7% in cucumbers,
13.3% in watermelons, 11.7% in strawberry, 10.2% in
peanuts, 7.2% in cabbages, 7.0% in tomatoes, 6.9% in
ginger, 5.4% in eggplants and 5.4% in turnip. The results
of these years showed: the yield increase of vegetables
with longer growth periods was more than that of vegetables
with shorter growth periods; The yield increase in vegetables
treated with less nitrogen fertilizers was more significant.
Some pests can be controlled to some degree, such as
powdery mildew in strawberry and downy mildew in cucumbers.
The time of occurrence of pest can be delayed by 5 days.
Treatment with calcium cyanamide can also lead to the
reduction in the content of nitrogen in the plants and
improve the quality of plants. For example, the sugar
in the watermelons treated with calcium cyanamide was
increased by 0.7 compared with the watermelon treated
with the same amount of urea. The treatment with calcium
cyanamide led to the advanced maturity by 3-7 days and
the elimination of all kinds of weeds. In the fields
treated with calcium cyanamide, there were no weeds
after 10 days of the planting. After 30 days, some weeds
come out, however the growth speed and numbers were
reduced remarkably. |
