Abstract

The invention discloses a bioorganic fertilizer used for improving soil. The bioorganic fertilizer comprises 100-1000 parts by weight of straws, 1-10 parts by weight of straw decomposition agent, 10-100 parts by weight of animal dung and 1-10 parts by weight of inorganic fertilizer, wherein the straw decomposition agent is prepared by fermenting bacillus subtilis, aspergillus oryzae, trichoderma reesei, phanerochaete chrysosporium and geobacillus stearothermophilus. The bioorganic fertilizer has the beneficial effects that the prepared organic straw fertilizer is used as a base fertilizer, so that the contents of available nitrogen, rapidly available phosphorus, potassium and organic matters in soil are higher than those of available nitrogen, rapidly available phosphorus, potassium and organic matters in the soil in which straws are directly used and fertilizers are not applied; the urease activity and cellulase activity of the soil are obviously improved compared with those of the soil in which straws are directly used and fertilizers are not applied.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to the application of a biological organic fertilizer in soil improvement. Background technique [0002] With the development of agricultural technology, chemical fertilizers have also been widely used, but it has caused many problems. If chemical fertilizers are used in large quantities for a long time, the soil structure will be destroyed and soil fertility will decrease, which will not only reduce the benefit of increasing production, but even pollute the environment. [0003] Compared with chemical fertilizers, microbial fertilizers have obvious advantages in improving fertilizer use efficiency, increasing crop yields and protecting the ecological environment. However, its cost is high, resource utilization rate is low, and the effect of increasing production is not as good as that of chemical fertilizers, so it has not been widely used. [0004] Crop straw is a huge resource with the ...
