Description
Technical field:
The present invention relates to agricultural fertilizer field, particularly relate to a kind of preparation method of biological organic fertilizer, be specially the preparation method of the special rich zinc-iron biological organic fertilizer of a kind of fresh edible maize.
Background technology:
Zinc (Zn) is the necessary natural element of growth and development of plants and animals, the existence of zinc is had in the rock of most of earth's crust, average content is about 70mg/kg, average content in the outer field litre geosphere of the earth's crust, pedosphere and biosphere is about 50mg/kg, and in hydrosphere, the contents level of zinc is all lower is about 0.01mg/kg.All there is the situation of scarce zinc in the part soil of the calcareous soil of the northern area of China and the saline soil of coastland and southern area, in the area that some scarce zinc are serious, the shortage of ZINC IN SOIL element has become the principal element limiting local Agriculture Production.
People will take in the zinc element of 15-25mg every day by food, body just can be made not lack zinc, and many areas find to lack zinc in food chain by research, can be serious affect the healthy of local resident especially teenager and children.The zinc of needed by human body is mainly derived from plant from soil, absorbs the zinc obtained.Due in soil and crop in lack zinc and cause the output of crop reduce and quality decline phenomenon worldwide very general, the shortage of ZINC IN SOIL oneself become the restricted nutritional factor of crop growth, had a strong impact on the yield and quality of crop.
American science research committee is recommended, and people needs the amount taking in zinc to be 15mg at 11 years old to adulthood every day, and in the meals that Chinese NNFA is recommended, every day needs the amount supplying zinc to be also 15mg.According to the diet formula of Chinese residents, grownup takes in the amount of zinc at about lOmg every day, if that is the zinc content in food crop seed is brought up to original 2-3 doubly, just can ensure that intake reaches 15mg every day.3 kinds of approach are had: one is that cultivate can the staple food crop such as crop varieties, particularly wheat, paddy rice, corn of gathering trace nutritive element to food supplement trace nutritive element; Two is the materials adding certain micronutrient element or be rich in certain trace element in food; Three is use the fertilizer being rich in some micronutrient element, and combines with crop varieties, produces so-called functional foodstuff.First method length consuming time, input are also comparatively large, and also may involve transgenosis problem, what second method was supplemented is external source zinc, and the third method is more feasible way for current, has had some successful experiences at home and abroad.In recent years, a few thing had done in rich selenium, Fu Zi and Fu Tie rice and wheat in China, and what have applies in production fairly largely.
