Description
Technical field
The present invention relates to a kind of biological organic complex fertilizer, specifically a kind of improvement salt-soda soil type biological organic complex fertilizer
And preparation method thereof.
Background technology
Salt-soda soil refers to soil to be influenced by the factors such as natural or artificial, and salts substances is caused gradually to penetrate into soil
It goes, the saliferous and alkalinity to make soil are more, and cause this kind of soil that can not be used.China salt-soda soil substantially distributed area
Domain is in northwest, northeast, North China and coastal region, and salt-soda soil primarily forms the reason is that more work of the soil of arid area in evaporation
Under, moisture is evaporated into vapor, and is emitted into air, but the salinity in water cannot exclude and stay among soil,
By accumulating for a long time, salinity gradually increases in soil, therefore and forms salt-soda soil.By alkaline land soil institute saliferous itself
Point excessively high, according to plant cell osmosis principle, plant cell is difficult to be absorbed into inorganic nutrient substance and moisture, leads to plant
Because itself lacking inorganic nutrient substance and water due to death, therefore crops are difficult to be grown in salt-soda soil.Currently, global salt-soda soil
Increased with about 100 ~ 1,500,000 hectares every year of speed.It expands, disperse when salt-soda soil shows wet, is muddy, shunk when doing, is hardened,
Hard, the features such as permeability is poor, can cause plant physiology arid, influence crop normal nutrition and even poison and then influence grain
Yield and lead to Cultivated Land Area Decrease.
Chinese saline alkali land area is vast, and type is various, and transformation is administered and rational exploitation and utilization these resources are Chinese agricultures
One of important channel of sustainable development, while to improving the ecological environment, thrust zone economy, society and Ecological Sustainable Development
Have great importance.Agricultural fertilizer technology has very important effect to alkaline land improving, but current market sales of
Fertilizer does not have improving effect mostly to salt-soda soil, and some even can aggravate the salinization of soil.Therefore development ＆ production is for saline and alkaline
The fertilizer of ground improvement is necessary.
