Abstract

The invention relates to a controlled-release fertilizer special for rice and produced by monosodium glutamate mother solution, belonging to the fertilizer special for rice. Bacillus licheniformis is used for fermenting the monosodium glutamate mother to produce gamma-PGA (polyglutamic acid), NH4<+>, and P and K with certain proportion are added as required by rice, therefore, the controlled-release fertilizer special for rice is produced. The controlled-release fertilizer special for rice has the effects that as the ratio of nitrogen, phosphorus and potassium is reasonable, the amount of the fertilizer can be reasonably controlled to be applied according to the yield of rice and the nutrients can be reasonably supplied in balance according to the requirements of the rice for the fertilizer in different growth periods, the rice can grow vigorously, the percentage of earbearing tiller is improved, the spikelet number per panicle is increased, the maturing rate is improved, and the yield is increased; besides, the production cost is reduced, the fertilizer is convenient to use and can achieve the effects of increasing yield and income and synergism, therefore, the controlled-release fertilizer is the ideal fertilizer for rice.

Description

technical field [0001] The invention belongs to a special fertilizer for rice, in particular to the special fertilizer for rice produced by using monosodium glutamate mother liquor. Background technique [0002] my country is a big producer of monosodium glutamate, and its annual output ranks first in the world. For every ton of monosodium glutamate produced, 20 to 25 tons of high-concentration organic waste liquid, that is, monosodium glutamate mother liquor, must be discharged. Monosodium glutamate mother liquor refers to the waste liquid discharged after isoelectric separation and extraction of glutamic acid during the production of monosodium glutamate in the monosodium glutamate factory. When domestic monosodium glutamate factories extract glutamic acid from fermentation broth, they generally do not separate the bacteria first, but directly extract glutamic acid from the fermentation broth and its concentrate containing bacteria and protein, and more and more domestic m...
