Description
The present invention is fertile manufacturing and an application process of a kind of control release type paddy rice special blending (BB), belongs to the manufacturing technology of agricultural fertilizer.
The special-purpose BB fertilizer of crop (Bulk blending fertilizers) (Bulk Blending Fertilizer) is granular physics mixed type polynary fertilizer, and product nitrogen phosphorus potassium total nutrient content is the basic form that the current chemical fertilizer of north America region uses more than 50%.In recent years also obtain very fast development in countries such as Japan in Asia, Malaysia.Since 1987, we provide and add the associating of mixed fertilizer factory in the use technology of special-purpose BB fertilizer series nutritional formula parameter and product and the Guangdong Province, take the lead in developing special-purpose BB fertilizer at home.After this, provided the fertile factory of the BB that opens ground such as flat, middle mountain, sluice gate and Jiexi in the Guangdong Province of technical parameter and technical service successively to be constructed and put into operation in succession by us, the fertile annual production of the special-purpose BB of the various crops of our province in recent years reaches 10～150,000 tons.We deepen continuously and the large-scale development success the fertile research of the special-purpose BB of crop, and other research unit that has driven province, city and Guangdong such as Jiangxi, Xinjiang, Jiangsu, Fujian, Guangxi, Hunan, Hubei, Tianjin also carries out the research and the product development of this aspect.The ultimate principle of modern fertilization recommendation technology is mainly used in the preparation of the special-purpose BB fertilizer of crop: according to the regulation of fertilizer requirement of various crops, on the spot fertilizer provision from soil nutrient preserving capability energy and fertilizer effect, the suitable consumption of the various first fertilizers of antenatal formulation, thereby the nutritional formula of the special-purpose BB fertilizer of formulation Different Crop.The various materials of the special-purpose BB fertilizer of crop require its particle diameter and proportion to be complementary, and mixed product can not produce the adverse chemical reaction and the moisture absorption threshold value obviously descends.The basic material that now clearly is fit to preparation BB fertilizer comprises coarse grain urea, diammonium phosphate or double superhosphate and coarse grain Repone K etc.The process for processing of the special-purpose BB fertilizer of crop has had sophisticated a whole set of mechanical means, and product is used for the base manure of each object crop and topdresses.The special-purpose BB fertilizer of crop is the materialization of science technique of balanced fertilizer, can obviously improve effect of increasing production, productivity effect and the ecological benefits of fertilising than the traditional fertilization technology.But, also there is following main drawback in existing product: fertilizer efficiency is shorter, and the utilization ratio of fertilizer nutrient is still lower, needs the number of times of fertilising also more, because the ecological environmental pollution problem that fertilising causes is still more outstanding, the product long-term storage still can produce moisture absorption agglomeration problems etc.For controlled release fertilizer, the year production usage quantity of world's release and release control fertilizer is about 30～400,000 tons at present, only accounts for 0.1% of chemical fertilizer year total quantity consumed.There is north America region in the main place of production, Japan and West Europe etc., and product generally is used for garden crops such as high fruit tree of playground meadow, green lawn and economic worth and flowers.Release and release control fertilizer also is in the experimental study stage substantially in China, and in agriculture production, especially the use on field crop produces is very few at present.But no matter domestic and international, the research of the special-purpose BB fertilizer of control release type crop and production are used and are not seen also all that at present report is arranged.Release and release control fertilizer is meant by physics or chemistry route, and the control fertilizer nutrient is the dissolution rate of nitrogen nutrient especially, matches or synchronous fertilizer type in the hope of the rate of release of fertilizer nutrient and fertilizer provision from soil and the crop demand rule to nutrition.The fertilizer efficiency of release and release control fertilizer can be kept several months, 1 year even several years, thereby reaches the plant recovery of nutrient height, purpose such as fertilizer efficiency is long, fertilizer application frequency is few, use safety, ecological environmental pollution reduction.At present, the method of controlling quick-acting chemical fertilizer rates of release mainly can branch condensation method and coating method two big classes: condensation method is that matrix and other material condensation form water-soluble lower polymkeric substance with urea or other instant nitrogenousfertilizer generally, in soil, can decompose, progressively discharge nutrient by biological and chemical; The coating method can be divided into two kinds of organic polymer and inorganic polymer coatings: the organic polymer coating can be used the polymer thermoforming plastic, and parcel one deck has the film of micropore on chemical fertilizer granule, and nutrient can progressively outwards ooze out by micropore; Also slow photodissociation of available energy or biodegradable polymer organic polymer thin film Wrapped fertilizer particle; The inorganic polymer coating sprays into fused inorganic polymer (commonly used have sulphur, paraffin, pitch etc.) and makes the fertiliser granulates surface form a skim when generally fertiliser granulates being preheated to 65～70 ℃, nutrient release rate can be regulated by membrane wrapping thickness.Mainly there is the shortcoming of following two aspects in present release and release control fertilizer: the one, and production cost or use cost are too high, are generally the several times of chemical fertilizer commonly used, and the popularity of its application is severely limited; The 2nd, nutrient release rate is difficult to meet crop to law of nutritive absorption, or in crop growth nutrient supply deficiency in early stage, or too small in late growth stage nutrient supply speed.
Purpose of the present invention is exactly not have in order to overcome and to solve existing BB fertilizer (Bulk Blending Fertilizer) and controlled release nutriment in a fertilizer that fertilizer efficiency is short, the fertilizer nutrient utilization ratio is low, the need fertilizer application frequency is more, production cost is higher, it is restricted to apply, nutrient release rate is difficult to meet shortcoming and the problem of crop to law of nutritive absorption etc., research invention a kind of fertilizer efficiency length, fertilizer efficiency plant recovery of nutrient height, production and use cost is low, fertilizer application frequency is few, easy to use, nutrient release rate meets manufacturing and the application process of crop to control release type paddy rice special blending (BB) fertilizer of law of nutritive absorption.
The present invention realizes by following technical proposals: each the component materials nutrient content (%) and the weight percent recipe ratio that feeds intake thereof that control release type paddy rice special blending (BB) is fertile are:
