Abstract

The invention discloses a preparation method of a corn straw fermented organic fertilizer for sea rice. The preparation method comprises the following steps: (1) obtaining corn straw powder; (2) obtaining a mixed solution; (3) obtaining an alkaline mixed material liquid; (4) obtaining a fermentation product; and (5) adding decomposed cow dung accounting for 10-15% of the mass of the fermentation product obtained in step (4) into the fermentation product, performing uniform stirring, and performing standing at normal temperature for 10-12 h so as to obtain the organic fertilizer. The prepared corn straw fermented organic fertilizer can improve the yield of the sea rice, and also can shorten the growth cycle of the sea rice.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for preparing an organic fertilizer fermented with corn stalks for seawater rice. Background technique [0002] Seawater rice is a name for "salt-alkali-tolerant rice", which means rice that grows in saline-alkali land, including tidal flats by the sea. The area of ​​saline-alkali land in China ranks third in the world, and the area with potential for agricultural development accounts for more than 10% of China's total arable land. According to the recent experimental results of Yuan Longping's scientific research team, after the large-scale promotion and planting of seawater rice, it can add 30 billion kilograms of grain to China every year, which is of great significance to ensure the food security of our country. Therefore, how to better improve seawater rice through reasonable fertilization Yields are of great economic importance. [0003] Crop stra...
