Law of proved recipe of requirement of the classification that this standard provided product of nitrogen-fixing bacteria fertilizer, technology, check, test gauge criterion, pack, label, carry, keep in storage.

This standard applies to the nitrogen-fixing bacteria that contains increase, can be in soil and the nitrogen in air is being secured in a variety of crop root border, offer nutrition of crop nitrogen element, the live system that can secrete hormone to stimulate crop to grow again is tasted. This standard also applies to what give priority to with nitrogen-fixing bacteria to contain can promote solid nitrogen, growth plant to close to rooted border bacterium (PGPR) fertilizer of compound nitrogen-fixing bacteria.

This standard uses following definition.

31 autogenous nitrogen-fixing bacteria

In the in can fixed air nitrogen in soil, offer nutrition of crop nitrogen element, what can secrete hormone to stimulate crop to grow again is microbial.

32 border combine nitrogen-fixing bacteria

Depend on root border environment to grow already, secure the nitrogen in air in root border again, what to the growth of crop development produces positive effect is microbial.

Efficiency of 33 solid nitrogen

Every use up nitrogen-fixing bacteria 1g carbohydrate (candy) the milligram number that absorbs azotic element from inside air, solid nitrogen efficiency uses Mg nitrogen / G candy expresses.

4 products are classified
