Description
Technical field
The invention belongs to the research field of fertilizer and preparation method thereof, more particularly to a kind of bacteria agent and edible fungi residues and
Chicken manure is compound fertilizer of primary raw material and preparation method thereof.
Background technology
Alfalfa (Medicago satica L.) be China's distribution is most wide, cultivation history at most, economic value highest
Leguminous forage, be described as " King of Pasture ".Alfalfa is to the development of promotion save-grain animal husbandry and improves milk unit yield,
Ensure that milk quality plays an important roll.
Initial estimate, in alfalfa hay per ton phosphorus element containing 6kg (P2O5) and 26kg potassiums (K2O) and calcium and magnesium sulphur and
Other trace elements.Relative to other crops, alfalfa has higher nutritional need, and the nutrition condition of soil is to pale reddish brown lucerne
The growth of Mu plays an important roll.Sufficient potassium nutrition can not only strengthen the resistance of clover, extend the life-span, can also carry
High tolerance and winter cabbage to cradling.Phosphorus element can ensure the healthy growth of plant seedling stage, improve alfalfa production
Amount.Micronutrient boron promotes new tissue growth and stem's elongation.Molybdenum promotes the activity of biological nitrogen fixation enzyme, to improving alfalfa
Nitrogen-fixing efficiency plays an important roll.Per hectare alfalfa every year can be with 40~420kg of fixed nitrogen, with soil nutrient state and field
Manage closely related.
Good fertilizer management can increase Alfalfa Output and utilization periods, reduce fertilizer cost and then increase economical
Benefit, blindly fertilising are then run counter to desire.Certain nutrient excess can limit the absorption of other nutrients so that yield does not rise anti-drop.Example
The absorption of calcium, magnesium, sulphur can be promoted by such as increasing soil available phosphorus content, but can limit potassium absorption, and increase available potassium is then reduced
The absorption of manganese, zinc, calcium, boron, therefore it is noted that reasonably combined during fertilising.
Fertilizing systems are seldom carried out using soil testing or fabric analysis in China's ALFALFA PRODUCTION at present, apply fertilizer with feeling and
Experience.But because alfalfa itself can carry out biological nitrogen fixation using rhizobium, therefore clover is to nitrogen nutrition in soil
Demand is not high, and alfalfa can also provide a considerable number of nitrogen nutrition for succession crop, so in actual production,
The producer is larger to the usage amount of nitrogenous fertilizer, in fact, clover clover seedling stage or Radical extension be bad or a large amount of ineffetive nodulations or
Applied nitrogen is needed in the case of pH ＜ 6.5 soil；It is less than 15ppm in soil nitrate-N, organic matter is less than 1.5% (such as sand
Property soil) in the case of need applied nitrogen；After planting the soil moisture needs applied nitrogen in the case of being consistently less than 15 DEG C；Lucerne
