the ways of Strawwing Field

to Straw Field,it can enrich the element of vegetables.at last,it is associated with health.
Field crops(fresh vegetables) straw is added and the balance of soil nutrients, soil improvement of the effective ways is to raise the utilization rate of resources, Festival of the efficiency and improve the fertility of arable land base effective means for sustainable agricultural development is of great significance.
According to the study with the experimental results shows field corn straw 500 kg. Application Chaduofei equivalent to 2,500 kg, 11.7 kg ammonium bicarbonate, SSP 6.2 kg and 4.95 kg of potassium sulfate; After a year of soil organic matter content relative increase 0.05% - 0.23%, P 0.03% average increase. K increased 31.2 mg / kg, soil capacity decreased 0.03% - 0.16% g/cm3, improve soil porosity 2% - 4% increase fertility consecutive years, straw Tin, not only can improve the utilization rate of phosphorus and potassium supplement inadequate soil, soil fertility is to be raised 0.5-1 rating.
In addition, the refractory solid root vegetables and flowers withered stalk deal with the resources of the Department with respect, domestic and foreign scholars have made more research; First, focus on the use of biodegradation treatment and high temperature composting cellulolytic bacteria in biological function; Second, feedback temperature control ventilation joint composting; But these methods need to increase labor costs and ventilation equipment. Another straw used cauliflower and fresh pig manure and composting of organic mixtures retting natural fermentation 35 days after the field test, achieved good results, facilitate the spread of farmers that the law is the promotion.
