Henan compost organic fertilizer equipment fertilizer equipment manufacturing company Viet compost maturity is good or bad, is the identification of a comprehensive index of quality compost. According to their color, odor, hardness straw, compost leachate, compost volume, N ratio and to determine the coefficient of detritus. (1) the smell from the color, the maturity of compost straw brown or dark brown, biogas sludge organic fertilizer production line equipment, juice black, with ammonia odor, fast testing with ammonium reagent, a significant increase in its ammonium content; ( 2) the hardness of straw, compost by hand, warm and soft and flexible; dry very brittle, easily broken, organic matter loss of elasticity; (3) compost leachate, take maturity compost, add water after mixing (fertilizer ratio of 1: 5-10 ), place 3-5 minutes, the pale yellow leaching solution; (4) compost volume, than just stack shrink 1 / 2-2 / 3; (5) N ratio, is generally 20-30: 1; (6 ) humification coefficient of about 30%. Composting of organic fertilizer equipment achieve these targets compost is good quality compost fertilizer, it can be applied to a variety of soils and crops. Adhere to long-term administration, not only to obtain high yield, biogas sludge organic fertilizer equipment and technology, but also to improve soil and soil fertility have significant effects. Straw organic fertilizer equipment Henan Viet organic fertilizer equipment Chinese farmers use crop residues have excellent long history, just as the previous low level of agricultural production, low yield, low quantity of straw, the straw with the exception of some small amount for the washer, fed to livestock, in the compost heap, most are burned for fuel. Straw organic fertilizer equipment R & D with the development of agricultural production, China since the 1980s, a substantial increase in grain yield, straw and plentiful, coupled with the promotion of firewood coal technology, biogas sludge organic fertilizer equipment prices, coal and use liquefied petroleum gas, which made a large number of rural surplus straw. At the same time the progress of science and technology, biogas sludge organic fertilizer equipment, improve agricultural mechanization level, so from the original use of straw into compost heap Straw. China's science and technology workers to straw conducted fruitful research. There retting straw to field, had abdominal Field directly to field a variety of ways. Henan Viet organic fertilizer equipment plowing the crop straw to field or mulching is an effective stimulation. Straw test results "eight five" during the Chinese Academy of Agricultural Sciences, Southwest Agricultural University, Hubei Academy of Agricultural Sciences and other units showed that after the implementation of straw can often yield more than 10 percent, the National Statistics more than 60 materials, increase the range of -4.8 ~ 83.4, the average yield of 15.7%. Adhere to the perennial straw, not only yield significant role in the fertilization stage, but the aftereffect is very clear, there is continuous increase yield. In response to the national agricultural farmer-friendly policy. . Small biogas sludge organic fertilizer equipment, organic fertilizer equipment Viet, biogas sludge organic fertilizer equipment supplied by Henan Viet fertilizer Equipment Co. Fertilizer Co., Ltd.
