Description
Technical field
The present invention relates to technical field of agricultural fertilizers, particularly relate to one type of slow-release compound fertilizer special for serotinous mandarin orange.
Background technology
China's citrus accounts for 75% in the medium variety of ripe listing of the 11-12 month at present, and the early maturing variety that the 9-10 month goes on the market accounts for 20%, and the late variety after December only accounts for about 5%, and the annual 3-9 month is the neutral gear of the self-produced citrus of China.Therefore, can avoid the peak hour that the citrus late variety of listing lacks is that China's citrus industry faces for a long time, needs to be resolved hurrily and unsolved major issue.
Citrus is evergreen fruit trees, several times a year takes out the tip, and vegetative period is long, and result quantities is big, and fertilizer requirement is big, and its total fertilizer requirement is equivalent to about the twice of deciduous fruit tree.For a long time, citrus is planted and is adopted traditional phosphate fertilizer, common composite fertilizer and a small amount of urea to combine repeatedly mode of administration always, and the balance of nutritive element, the innocuousness of fertilizer quality are also paid attention to inadequately.Fallen leaves in winter, preharvest drop problem that cultivation management technology falls behind due to the especially nutrient supply imbalance are the major reasons that late-maturing citrus is difficult to develop.Still do not have on the home market at present and be fit to late-maturing citrus growth characteristic and the nuisanceless long-acting specific composite fertilizer material that improves nutritional quality.Therefore, according to the nutrient environment condition of late-maturing citrus growth, development and science are used the citrus compound fertilizer special of the compound slow release type of organic-inorganic, are the late-maturing citrus standardized cultivation of China and assurance product high yield, high-quality, nutrition, safe pressing for.
Summary of the invention
The present invention aims to provide the nutrient demand characteristics of one type of ability according to late-maturing citrus fruit picking phase (the 3-5 month), strong fruit phase (the 7-9 month) and bud phase in spring (the 2-3 month); Whole process satisfies the special-purpose serial slow-release compound fertilizer of late-maturing citrus that is the basis with the high-quality organic fertilizer of late-maturing citrus nutritional need; Problems such as fertilizer quality in the late-maturing mandarin orange planting is lower to solve, the winter fallen leaves of nutrient structure due to uneven, preharvest drop, and then guarantee late-maturing citrus high-quality, stable yields and high yield.
The special-purpose serial slow-release compound fertilizer of late-maturing citrus of the present invention divides A, B, C type, is fit to respectively use in late-maturing citrus fruit picking phase, strong fruit phase and three periods of bud phase in spring.
A type fertilizer is made up of each following component of mass percent: urea 16%～18%, primary ammonium phosphate 6%～7%, vitriolate of tartar 15%～16%, potassium primary phosphate 5%～6%, ammonium sulfate 8%～9%, two cyanogen ammonium 1%～2%, thiocarbamide 1%～2%, boric acid 1%, zinc sulfate 0.5%, sal epsom 1%, ammonium molybdate 0.5%, rapeseed meal 15%～18%, the paulownia dregs of rice 3%～5%, feather meal 9%～13%, bone meal 4%～5%, zeolite 5%;
Type B fertilizer is made up of each following component of mass percent: urea 9%～10%, primary ammonium phosphate 7%～8%, vitriolate of tartar 12%～13%, potassium primary phosphate 10%～12%, ammonium sulfate 8%～9%, two cyanogen ammonium 2%, thiocarbamide 2%～3%, boric acid 1%, zinc sulfate 0.5%, sal epsom 1%, ammonium molybdate 0.5%, rapeseed meal 15%～17%, the paulownia dregs of rice 4%～5%, dregs of beans 11%～13%, bone meal 6%～8%, zeolite 5%;
C type fertilizer is made up of each following component of mass percent: urea 17%～18%, primary ammonium phosphate 7%～9%, vitriolate of tartar 11%～12%, potassium primary phosphate 6%～8%, ammonium sulfate 8%～9%, two cyanogen ammonium 2%, thiocarbamide 2%, boric acid 1%, zinc sulfate 1%, sal epsom 0.5%, ammonium molybdate 0.5%, rapeseed meal 14%～16%, the paulownia dregs of rice 3%～5%, dregs of beans 5%～9%, bone meal 8%～9%, zeolite 5%～8%.
The A type is that fruit picking is fertile, the low-phosphorous type of potassium in the high nitrogen, N: P
2O
5: K
2O=14: 7: 10, organic 15%～17%; Used in 5-7 days after the fruit picking, purpose is being recovered tree vigo(u)r.
Type B is fertile for strong fruit fruit retention, nitrogen phosphorus potassium balance type, N: P
2O
5: K
2O=11: 10: 10, organic 23%～25%; Use 8～September, has fruit retention and promote autumn growth to extract out and the bud differentiation effect.
The C type is that the spring bud is fertile, the low-phosphorous potassium type of high nitrogen, N: P
2O
5: K
2O=14: 8: 8, organic 19%～21%; The spring bud is extracted preceding (January) 10～15 days out and is used, and purpose is promoting that spring tip growth and flower bud development are good.
The requirement of A, B, C type fertilizer material is: urea contains N>=46%, and primary ammonium phosphate contains N>=15%, P
2O
5>=40%, potassium primary phosphate contains P
2O
5>=49%, K
2O>=32%, vitriolate of tartar contains K
2O>=50%; Ammonium sulfate contains N>=21%, and two cyanogen ammoniums contain N>=66%, thiocarbamide and contain N>=31%, boric acid and contain B>=17%, sal epsom and contain that Mg>=9.5%, zinc sulfate contain Zn>=18%, ammonium molybdate contains Mo>=49%, rapeseed meal particle≤0.4mm, paulownia dregs of rice particle≤0.4mm, dregs of beans particle≤0.4mm, feather meal particle≤0.4mm, zeolite granular≤0.25mm.
The method of manufacture of the special-purpose serial slow-release compound fertilizer of late-maturing citrus of the present invention is following:
Urea, primary ammonium phosphate, vitriolate of tartar, potassium primary phosphate, ammonium sulfate, ammonium molybdate, zinc sulfate, sal epsom, boric acid, two cyanogen ammonium, thiocarbamide and zeolite mixing with respective quality per-cent; The organic double compound that adds rapeseed meal, the paulownia dregs of rice and dregs of beans or feather meal then through effectuation and harmless treatment; Fully stirring and evenly mixing is processed granulation and is promptly got the special-purpose serial slow-release compound fertilizer product of late-maturing citrus.
The effectuation and the method for innocent treatment of rapeseed meal, the paulownia dregs of rice and dregs of beans or feather meal are: the mixture drying and crushing of rapeseed meal, the paulownia dregs of rice, dregs of beans or the feather meal and the bone meal of respective quality per-cent to particle≤0.4mm, is added the H of 3mol/L successively
2SO
4HNO with 2mol/L
