Abstract
The invention relates to a controlled-release fertilizer special for honeysuckle as well as preparation and an application thereof. The controlled-release fertilizer special for honeysuckle is prepared by proportionally mixing the following components: organic fertilizer microelement fertilizer composite, sulfur high polymer coated urea, 5% humic acid coated urea, 4% modified epoxy resin coated potassium nitrate with urea priming coat, 4% modified epoxy resin coated diammonium phosphate with urea priming coat, 5% humic acid coated compound fertilizer and NPK compound fertilizer. Based on nourishment absorption characteristics of honeysuckle in a yearly growth cycle, different controlled-release fertilizers are used as raw materials for precise complexing and coordinated with a granular organic fertilizer, thereby effectively improving the fertility of soils, improving the utilization efficiency of the fertilizer and promoting the high and stabile yield of honeysuckle; and the controlled-release fertilizer can be applied once, thereby saving labor.
Description
Technical field
The present invention relates to a kind of release and release control fertilizer, particularly the organic-inorganic release and release control fertilizer of Japanese Honeysuckle special use and preparation and application belong to release and release control fertilizer production and applied technical field.
Background technology
Japanese Honeysuckle is the perennial liana shrub that integrates medicinal economical and soil and water conservation ecological type.Japanese Honeysuckle is the traditional rare Chinese medicine of China, and is huge to its demand both at home and abroad.China is the main product state of Japanese Honeysuckle, and the cultivation history in more than 260 year is arranged, and the Japanese Honeysuckle kind is implanted with vast potential for future development.
Japanese Honeysuckle is to be the plant of product with the flower, and in the year breeding cycle many batches gather, so it is different with most of plants to nutrient demand.At first, blooming is reproductive growth, the plain nutrition of phosphorus that this process need is more.Secondly, nourish and grow and the reproductive growth parallel time long, different nutritive element supplies must be coordinated, otherwise easily make both imbalances of growing, and influence output.Japanese Honeysuckle fertilising at present is mainly based on readily avaiable fertilizer, and these fertilizer dissolve in soil soon, and fertilizer efficiency is short, and nitrogen, potash fertilizer easily run off.Owing to directly contact with soil, phosphate fertilizer is easily by soil fixing.In order to satisfy the demand of different growth phases, Different Nutrients kind, Japanese Honeysuckle need repeatedly be applied fertilizer in the year growth cycle, this has not only increased peasant's workload and labour cost, because frequent ditching fertilising has also injured a large amount of root systems, further influences nutrition absorption and improves output.
CN101885641A (CN200910027591.0) provides a kind of Japanese Honeysuckle herbal medicine nutrition fertilizer, and constitutive material is dried human excrement, dried goose excrement, dried pig manure, dried rabbit excrement, sorghum flour, bone meal, soybean cake powder, cotton seed hulls powder, chemical fertilizer, urea, nitrogenous fertilizer, glucose powder etc.Getting material combination stirs together, pulverizes, putting into stirrer again stirs, pour in the fermentation vat then, adding 1: 1.5 human excrement mixes thoroughly under waterborne and piles heap, with the plastic cloth fermentation 25 hours that is tightly compacted, carry out the turning first time, add 1: 1.5 human excrement after the turning in proportion again and mix thoroughly under waterborne and pile heap, carry out the turning second time with the plastic cloth fermentation that is tightly compacted after 44 hours, pile heap and ferment again and got final product in 70 hours.With the nutritious fertilizer that ferments put into mould close break into the fertile piece of nutrition qualified nutrition fertilizer.Though this fertilizer belongs to compound organic and inorganic fertilizer, does not have controlled-release effect, can not discharge according to the nutrient demand control nutrient of Japanese Honeysuckle.
Current production is a kind of not only met Japanese Honeysuckle absorbing rule, but also the release and release control fertilizer kind that can carry out the fertilising of annual property be to improve the key of Japanese Honeysuckle Fertilization Level.Up to now, the relevant report of Shang Weijian.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of organic-inorganic release and release control fertilizer and preparation and application of Japanese Honeysuckle special use.
Summary of the invention
The present invention utilizes different controlled release fertilizer accurately composite as raw material, and cooperates with granular organic fertilizer according to nutrition absorption characteristic in the Japanese Honeysuckle year breeding cycle, can effectively increase soil fertility, and increases fertilizer utilization efficiency, the stable high yield of security deposit's honeysuckle flower.

5～8 fertilising holes are dug in the application of Japanese Honeysuckle special-purpose control-release fertilizer of the present invention on 20～30 centimetres of circumferential lines of stump before Japanese Honeysuckle rudiment in spring, cheat dark 20～40 centimetres.Fertilizer is disposable all to be used.Fertilizer amount, folding synthetic nitrogen, phosphorus, potassium total amount, 400～500 kilograms of per hectares.Further preferred, fertilizer of the present invention with use after the soil of 2～3 times of weight mixes, perhaps, in the fertilising hole and about isopyknic soil puddle after earthing.
Excellent results of the present invention is as follows:
1, organic-inorganic combination is increase soil fertility
The sign of fertile soil is not only the nutrient content height, also is embodied in the ability of reconciling water, gas, heat.Mainly in the mountain area plantation, soil fertility is poor, and is structural bad, a little less than the preserve moisture and fertility ability for Japanese Honeysuckle.Special-purpose control-release fertilizer of the present invention contains abundant organic substance, the required various inorganic nutritive elements of Japanese Honeysuckle are arranged simultaneously, and being manured into soil both can provide nutrient, also can promote the formation of soil aggregate, strengthen the ability of soil water-retaining, guarantor's fertilizer and conciliation water, gas, heat, increase soil fertility.
2, fertilizer nutrient discharges and is fit to Japanese Honeysuckle absorption requirement
Japanese Honeysuckle special organic and inorganic release and release control fertilizer of the present invention is to the nutrient absorbing characteristic according to different developmental phases in the Japanese Honeysuckle year growth cycle, utilize the multiple controlled release fertilizer of different coated fertilizers, different controlled release phases to do accurately composite forming of raw material, nutrient discharges and meets Japanese Honeysuckle absorption requirement, improve utilization rate of fertilizer, increase Japanese Honeysuckle output.
3, improve micro-utilising efficiency
The trace element that adds in the composite controlled release fertilizer of Sheng Chaning mostly was Powdered or crystalloid in the past, and was too big with the fertile granular size gap of controlled release of 2～4 millimeters particle diameters, was not easy to mix the effect of influence trace element.Fertilizer of the present invention is mixed in trace element in the fertilizer, has both solved the problem of incomplete mixing, has also reduced because of directly contacting the fixed action that causes with soil simultaneously, has improved micro-fertilizer efficiency utilising efficiency greatly.
4, reduce fertilizer application frequency, save labour cost
In present the production, Japanese Honeysuckle is mainly used readily avaiable fertilizer, because this class fertilizer dissolves in soil soon, fertilizer efficiency is short, generally needs fertilising 3 to 4 times in year growth cycle of Japanese Honeysuckle.Special-purpose control-release fertilizer of the present invention only needed fertilising 1 time in 1 year, had reduced fertilizer application frequency, had saved labor capacity, had reduced labour cost, had improved planting benefit.
