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.

Methods of application:
     1.Application as base fertilizer.

Name of crops	Disease and grass	Volume	Timing	Numbers	Methods
Rice	Weeds in the paddy fields	33-46	Before sowing or seedling	once	Treatment on the weed 2 or-3 days prior to plough. Even mix with soil. After 5-8 days, begin to plant.
	Snail	20-40	Same as above		Put water of 3-4cm in the field. After 3-4 days, begin to scatter. Then after 3-4 days, begin to seed.
	Pomacea etc.	13-20	Before seedlings		Put 3-4cm water and then scatter. After 3 -4 days, begin to seed
	Wild barn grass	40--50	One week after harvest		Scatter
Wheat	Weeds and insects	33-46	Before planting		Mix with soil before plough. After 5-8 days, begin to plant.
Vegetables	Worm, weeds and other insects	33-66	Before sowing or planting		Mix it with soil for 7-10 days and then plant vegetables. In summer, it can be applied with organic fertilizers, then watering and then are covered with PE film for disinfections.
Flowers	Disinfections of soil	1%-3% of soil in pot			Mix it with soil and then put water. after covered with film for 4-7 days, begin to plant.
