Abstract
The invention discloses a special controlled release fertilizer for chitosan coated mangoes and a preparation method of the special controlled release fertilizer, and relates to the technical field of special slow controlled release fertilizer for fruits. Following the rule of mangoes to absorb nutrients, 4% chitosan coated urea, 6% chitosan coated urea, urea, ammonium sulfate, calcium superphosphate, calcium magnesium phosphate, potassium sulfate and sodium borate are compounded, blended by a blender, weighed, and packed to obtain the special controlled release fertilizer. The special fertilizer has the advantages that the utilization of nitrogen, phosphorus and potassium in the fertilizer is high, the fertilizer coatings is biodegradable so as to reduce pollution to the environment, the price is cheap, and formulation of nutrients is reasonable.
Description
Technical field
The invention belongs to fruit specialty slow-release or control-release fertilizer production technical field, be specifically related to a kind of mango special-purpose control-release fertilizer and preparation method thereof.
Background technology
Mango is nutritious, sugar degree and heat high, and vitamin A and Vitamin C content are extremely abundant, the sweet cunning of pulp fragrance, and local flavor is original in style, has the honor of " torrid zone is the king really ".The mango fertilizer requirement is big, and 1000 kilograms of bright mango of every production need nitrogen (N) 1.74 kilograms, phosphorus (P
2O
5) 0.23 kilogram, potassium (K
2O) 2.0 kilograms, but the mango of the different age of tree, different areas, different output level, there is very big-difference in fertilizer requirement, should decide according to practical situation during application.
1, flower forcing is fertile
Blooming was the mango flower bud differentiation period in preceding 1 month, and fertilizer should be main with quick-acting nitrogen, potash fertilizer, and consumption is about about 20% of annual consumption, 0.3～0.5 kilogram of every strain sealing fertilizer.
2, strong fertilizers for potted flowers
The mango amount of blooming is big, and nutrient consumption is many, should impose instant nitrogenousfertilizer 1 time at the florescence.Strong fertilizers for potted flowers can be selected composite fertilizer for use, and 0.1～0.15 kilogram of every strain sealing fertilizer can combine foliage-spray 0.1% borax, 0.1%～0.2% potassium dihydrogen phosphate.
3, fruit-promoting fertilizer
Thanking and spending back about 30 days is fruit ramp developmental stage, during young fruit increases rapidly, impose fruit-promoting fertilizer, could satisfy the needs of fruit development to nutrient, about 0.5 kilogram of general every strain sealing fertilizer.
4, urge the strong tip of the tip fertile before and after the fruit picking
The mango result quantities is big, and consumption nutrition is many, and fertilising is executed better at twice before and after the fruit picking; Before and after fruit picking, can every strain execute 0.2～0.3 kilogram in urea for the first time, 0.1～0.2 kilogram in Repone K, fertilising is when the last tip begins to change green for the second time; Imbed weeds in conjunction with digging; Every strain applies 25～50 kilograms of fertilizers, and 0.5 kilogram of NPK can combine foliage-spray 0.2% potassium dihydrogen phosphate 1～2 time.
Coated fertilizer is to realize the fertilizer nutrient sustained release, improves one of main mode of its utilization ratio, but more expensive owing to employing coated fertilizer price at present, complex process, is difficult to reason such as degraded and causes release and release control fertilizer on the high side, has hindered applying of it.Therefore it is very necessary to develop and develop a kind of novel, efficient, inexpensive, biodegradable coating mango special-purpose control-release fertilizer.
Summary of the invention
Deficiency to prior art; The invention provides a kind of chitosan coated mango special-purpose control-release fertilizer and preparation method thereof; Utilize the Nutrient Release of chitosan coated fertilizer, the law of nutritive absorption according to mango carries out composite a kind of mango special-purpose control-release fertilizer that obtains simultaneously.
