Description
Technical field
The present invention relates to a kind of Fructus Artocarpi Heterophylli special formula fertilizer.
Background technology
Fructus Artocarpi Heterophylli
(ArtocarpusheterophyllusLam.)also known as " artocarpus heterophyllus ", Fructus Artocarpi Heterophylli result is on trunk or major branch.Originate in India, Malaysia, the Chinese introducing culture Fructus Artocarpi Heterophylli 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 fruit the heaviest in the world, and generally weigh 5-20kg, the heaviest more than 50kg, and Fructus Artocarpi Heterophylli fruit taste is sweet and give off a strong fragrance, and containing abundant sugar and protein etc., is of high nutritive value.Be described as " tropical fruit queen ".Fruit is except eating raw, and also can make cake, preserved fruit, beverage etc., crude fruit can make the batching of various dish; Tree body is also high-quality timber.According to incompletely statistics, current Chinese Fructus Artocarpi Heterophylli cultivated area about 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 about 120,000 t.Along with the development of Tourism Industry in China and the raising of living standards of the people, the demand of market to Fructus Artocarpi Heterophylli is increasing, and particularly fresh fruit aromatising flavour is sweet, and a lot of visitor very likes, and sales volume has the trend increased year by year.In addition, less investment, profitable, general 3-5 results, more than per mu yield 3000kg, average yield per mu value reaches ten thousand/year of 1-1.5.Be expected to become new way, good channel that vast farmers is shaken off poverty and set out on the road to prosperity.
But, because current Chinese Fructus Artocarpi Heterophylli is based on distributing smallholder cropping pattern, in management, ubiquity is gently planted light pipe, 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 for rainy season, rainfall is large, and fertilizer nutrient particularly nitrogenous fertilizer dissolves soon in soil, and easily run off rapidly, the utilization ratio of fertilizer is low, causes the serious wasting of resources, and poor effect.These two aspects all annoying Fructus Artocarpi Heterophylli and produce, and this is the fertile urgent problem of Fructus Artocarpi Heterophylli.From the formula fertilizer patent data applied for, be not also applicable to the special fertilizer of Fructus Artocarpi Heterophylli plantation.
Release and release control fertilizer to realize the nutrients release new-type fertilizer synchronous with Crop, according to the burst size of the growth demand modeling fertilizer nutrient of crop and release rate, can reach the efficient object of volume increase.If but it is high separately it to be used in Fructus Artocarpi Heterophylli cost, peasant's difficulty accepts, 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, carries out precisely composite, utilize humic acids to improve the characteristic of soil simultaneously, reduce the shortcoming that the independent input cost of sustained-controll-release fertiliser is too high, improvement soil, realize Fructus Artocarpi Heterophylli bloom before single fertilization, the later stage does not impose, save cost of labor, improve peasant to be benefited, and carry out a large amount of field experiment, the effect achieved.
The present invention is achieved by following technical scheme:
A kind of Fructus Artocarpi Heterophylli special formula fertilizer, it 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, fertile 80 parts of peptide urea 80 parts, urea aldehyde, calcium superphosphate 150 parts, potassium sulfate 400 parts, humic acids 50 parts, boron fertilizer 10 parts, 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 made up 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, and nitrogen content 43%, urea aldehyde fertilizer is the nitrogenous fertilizer of nitrogenous 38%.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, with vegetables oil and solidifying agent for main raw material, without the need to adding solvent in film-coated controlled release fertilizer manufacturing processed, and cleanliness without any pollution.
Excellent results of the present invention is as follows:
1, nutrient formula is reasonable
The present invention fully takes into account the soil characteristic that in the nutrient requirement characteristics of Fructus Artocarpi Heterophylli whole breeding time and tropical soil, phosphorus content is higher, appropriate Potassium is beneficial to the quality strengthening Fructus Artocarpi Heterophylli, with the addition of magnesium and boron, nutrient formula is reasonable, is conducive to the efficiency utilization of Fructus Artocarpi Heterophylli npk nutrient.
2, slowly-releasing combines with controlled release
Consider that Fructus Artocarpi Heterophylli absorption in early stage nutrient ability is more weak, 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, on the basis ensureing Fructus Artocarpi Heterophylli available nutrient demand in early stage, Controlled Release Fertilizer slow releasing, make crop nutrition content supply steadily regular, avoid the de-fertile and excessive growth of Fructus Artocarpi Heterophylli, reach single-dose application, meet the fertile requirement of need in Fructus Artocarpi Heterophylli one complete vegetative period, and the utilization ratio of nitrogenous fertilizer can be improved significantly.
3, organic-inorganic combines, and reaches the effect increased production and improve the soil
Traditional chemical fertilizer is all based on inorganic nutrients, fertilizer of the present invention is except inorganic nutrients, with the addition of the humic acids with effect of improving the soil especially, the acid-basicity of tropical acid soil can be improved, increase the crumb structure of soil, strengthen the surge capability of soil, for high yield lays a good foundation.
4, crop anti-adversity is promoted
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, 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 Fructus Artocarpi Heterophylli output significantly, improve utilization rate of fertilizer, utilization rate of nitrogen fertilizer brings up to 50 ~ 60%, realizes single fertilization, reduces by 2 ~ 3 fertilizer, saves manually, decreases production cost, can save fertilizer 10% ~ 20% in equal yield line situation.
