Description
Technical field
The present invention relates to a kind of Fructus Artocarpi Heterophylli special formula fertilizer.
Background technology
Fructus Artocarpi Heterophylli
(Artocarpus heterophyllus Lam.)claim again " artocarpus heterophyllus ", Fructus Artocarpi Heterophylli result is on trunk or major branch.Originate in India, Malaysia, Chinese introducing culture Fructus Artocarpi Heterophylli is the history of existing more than 1,000 year so far, at present in Hainan, Guangdong, Guangxi, Taiwan, Fujian and In Xishuangbanna of Yunnan and South Sichuan all have plantation.Fructus Artocarpi Heterophylli is the heaviest in the world fruit, the 5-20kg that generally weighs, and the heaviest 50kg that surpasses, Fructus Artocarpi Heterophylli fruit taste is sweet and give off a strong fragrance, and contains abundant sugar and protein etc., is of high nutritive value.Be described as " tropical fruit queen ".Fruit, except eating raw, also can be made cake, preserved fruit, beverage etc., and crude fruit can be made the batching of various dish; Tree body is also high-quality timber.According to incompletely statistics, current Chinese Fructus Artocarpi Heterophylli cultivated area approximately 10,000 hm
2left and right, wherein Hainan Province's Fructus Artocarpi Heterophylli cultivated area 0.66 ten thousand hm
2left and right, Guangdong Province's cultivated area 0.3 ten thousand hm
2left and right, other provinces and regions mostly are scattered plantation, annual production approximately 120,000 t.Along with the development of Tourism Industry in China and the raising of living standards of the people, market is increasing to the demand of Fructus Artocarpi Heterophylli, and particularly fresh fruit aromatising flavour is sweet, and a lot of visitors very like, and sales volume has the trend of increase year after year.In addition, less investment, profitable, general 3-5 results, more than per mu yield 3000kg, average yield per mu value reaches 1-1.5 ten thousand/year.Be expected to become new way, the good channel that vast farmers is shaken off poverty and set out on the road to prosperity.
Yet, because current Chinese Fructus Artocarpi Heterophylli be take distributing smallholder cropping pattern as main, in management, the light kind of ubiquity is gently managed, is heavily received light pipe, does not note in conjunction with soil improvement and effective rich water quality management, cause plant to can not get sufficient nutrient, Yield and quality is uneven.Meanwhile, because torrid areas is long rainy season, rainfall is large, and fertilizer nutrient particularly nitrogenous fertilizer dissolves soon in soil, easily runs off rapidly, and the utilization ratio of fertilizer is low, causes the serious wasting of resources, and poor effect.These two aspects are all perplexing Fructus Artocarpi Heterophylli and are producing, and this is the fertile urgent problem of Fructus Artocarpi Heterophylli.From the formula fertilizer patent data of having applied for, be not also applicable to the special fertilizer of Fructus Artocarpi Heterophylli plantation.
Release and release control fertilizer is can realize nutrient to discharge the new-type fertilizer of synchronizeing with Crop, can according to the growth demand of crop, control burst size and the release rate of fertilizer nutrient, reaches the efficient object of volume increase.But if it is high separately it to be used in to Fructus Artocarpi Heterophylli cost, peasant is difficult to be accepted, and is unfavorable for application.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of Fructus Artocarpi Heterophylli special formula fertilizer.
The present invention is according to the law of nutritive absorption of Fructus Artocarpi Heterophylli, different slow controlled-release materials is joined in common fertilizer, carry out precisely compositely, utilize the characteristic of humic acids improvement soil simultaneously, reduced the too high shortcoming of the independent input cost of sustained-controll-release fertiliser, improvement soil, single fertilization before realizing Fructus Artocarpi Heterophylli and blooming, the later stage does not impose, saved cost of labor, improve peasant and be benefited, and carried out a large amount of field experiments, obtained good effect.
The present invention is achieved by following technical scheme:
A Fructus Artocarpi Heterophylli special formula fertilizer, is characterized in that: by weight, its feed composition is N:P
2o
5: K
2o=18:10:20; 160 parts, the polyurethane coated urea of coating quantity 5%, 80 parts, urea, 80 parts of peptide ureas, fertile 80 parts of urea aldehyde, 150 parts of calcium superphosphate, 400 parts of potassium sulfate, 50 parts of humic acidss, 10 parts of boron fertilizers, 40 parts, magnesium sulfate.
The polyurethane coated urea of described coating quantity 5% refers to that coating layer quality is 5% of total mass.
Described urea aldehyde fertilizer refers to the slow-release nitrogen fertilizer that urea and formaldehyde reaction obtain.
Described humic acids is liquid.
Described N is comprised of with coated carbamide urea, urea aldehyde fertilizer, and its ratio of weight and number is; Urea: peptide urea: urea aldehyde is fertile: coated release-controlled urea=1:1:1:2.
Above-mentioned all raw materials are paid product, and wherein 5% polyurethane coated controlled-release urea, urea aldehyde fertilizer, peptide urea are produced by CNOOC Fudao Co., Ltd, nitrogen content 43%, and urea aldehyde fertilizer is nitrogenous 38% nitrogenous fertilizer.In above-mentioned raw materials, humic acids is liquid, and all the other raw materials are granular, and particle diameter is all within the scope of 3-4 millimeter.
In-situ surface of the present invention is reacted into membrane envelope fertilizer and refers to polyurethanes reaction film coated carbamide, take vegetables oil and solidifying agent as main raw material, in film-coated controlled release fertilizer manufacturing processed without adding solvent, cleanliness without any pollution.
Excellent results of the present invention is as follows:
1, nutrient reasonable ratio
The present invention fully takes into account the higher soil characteristic of phosphorus content in the nutrient demand rule of Fructus Artocarpi Heterophylli whole breeding time and tropical soil, appropriate Potassium is beneficial to the quality that strengthens Fructus Artocarpi Heterophylli, added magnesium and boron, nutrient reasonable ratio, is conducive to the efficient utilization of Fructus Artocarpi Heterophylli npk nutrient.
2, slowly-releasing combines with controlled release
Consider Fructus Artocarpi Heterophylli in earlier stage absorb nutrient ability a little less than, middle and later periods nutrient demand amount increases gradually, in Fructus Artocarpi Heterophylli special formula fertilizer raw material of the present invention, common urea is combined with urea aldehyde slow-release fertilizer and polyurethane coated urea, ensureing on the basis of Fructus Artocarpi Heterophylli available nutrient demand in early stage, Controlled Release Fertilizer slowly discharges, make crop nutrition content supply steadily regular, avoid the de-fertilizer of Fructus Artocarpi Heterophylli and excessive growth, reach single-dose application, meet the Fructus Artocarpi Heterophylli fertile requirement of need in a complete vegetative period, and can improve significantly the utilization ratio of nitrogenous fertilizer.
3, organic-inorganic combines, and reaches the effect that volume increase is improved the soil
Traditional chemical fertilizer is all to take inorganic nutrients as main, fertilizer of the present invention is except inorganic nutrients, added especially the humic acids with the effect of improving the soil, can improve the acid-basicity of tropical acid soil, increase the crumb structure of soil, strengthen the surge capability of soil, for high yield lays a good foundation.
4, promote crop anti-adversity
Peptide urea composition is to the obvious promoter action of having grown of farm crop, and the effect of enhanced endogenesis growth hormone, can make the well developed root system of crop, and robust plant strengthens anti-adversity ability and the immunizing power of farm crop.
5, effect of increasing production is good, time saving and energy saving.
Can increase significantly Fructus Artocarpi Heterophylli output, improve utilization rate of fertilizer, utilization rate of nitrogen fertilizer brings up to 50～60%, realizes single fertilization, reduces 2～3 times fertilizer, has saved manually, has reduced production cost, in equal yield line situation, can save fertilizer 10%～20%.
