Development of bio organic fertilizer
Based on the current situation of chemical fertilizer use and agricultural waste, it has become a hot spot of agricultural research at home and abroad to actively seek for efficient and environmentally friendly chemical fertilizer substitutes and actively explore the way of agricultural waste resource utilization. In this context, bio organic fertilizer, with its unique advantages, has built a bridge for the growth of agricultural wastes and crops, and opened up a sustainable development path with the circulation mode of "agricultural wastes bio organic fertilizer crops".

First of all, the application of bio organic fertilizer is an important way to improve the basic soil fertility and the quality of agricultural products. The original intention of bio organic fertilizer production line is to integrate the advantages of organic fertilizer and bio fertilizer, which not only helps to improve crop yield, but also can cultivate soil, regulate soil micro ecological balance, reduce the amount of inorganic fertilizer, and fundamentally improve the quality of agricultural products, which is in line with the direction of sustainable agricultural development and green agricultural production.

Secondly, the production of bio organic fertilizer is an important means of agricultural waste resource utilization. Agricultural waste contains rich nutrient elements and organic nutrients necessary for crop growth, which are made into bio organic fertilizer by resource utilization. Through the role of microorganisms, the mineral, humic and harmless organics are made to be absorbed and utilized by crops, which can not only relieve the pressure of agricultural waste on the environment, but also turn waste into treasure and obtain certain economic benefits.
Advantages of bio organic fertilizer
Bio organic fertilizer is a kind of microbial organic fertilizer, which is made by adding functional microbial agents to the composted materials for secondary fermentation, and then processing through fertilizer equipment. Compared with other fertilizers, it has the advantages of fertilizing soil and improving product quality.

Compared with chemical fertilizer, bio organic fertilizer has more complete nutrient elements. Long-term use of bio organic fertilizer can effectively improve the soil, regulate the soil and Rhizosphere micro ecological balance, improve the disease and insect resistance ability of crops, and improve the product quality.

Compared with farmyard manure, the fundamental advantage of bio organic manure is that the functional bacteria in bio organic manure have specific effect on improving soil fertility and promoting crop growth, while farmyard manure is naturally fermented and does not have the special effect of dominant functional bacteria.

Compared with bio fertilizer, bio fertilizer contains functional bacteria and organic matter. In addition to improving the soil, the organic matter itself is the living environment of functional bacteria, which is easy to colonize and play a role after being applied into the soil; while bio fertilizer only contains functional bacteria, and the functional bacteria may not be suitable for some soil environment, and cannot survive or play a role. On the other hand, bio organic fertilizer is cheaper than bio bacterial fertilizer.

To sum up, bio organic fertilizer, as an efficient, pollution-free and environmental protection product, is an inevitable choice for the sustainable development of agriculture.
