Description
Technical field
The present invention relates to a kind of method of utilizing coated with resin to produce the crop special-purpose control-release fertilizer, relate in particular to a kind of hot special controlled-release fertilizer for resin film coated leechee and preparation method thereof, belong to slow/controlled release fertilizer technology field.
Background technology
China cultivates lichee country the earliest in the world, and cultivated area and output all rank first in the world.Development also has Thailand faster, and output has occupied the world the 2nd between short many decades, and other also have cultivation as more than 20 countries such as India, Australia, the U.S..China's lichee cultivation mainly is distributed in provinces and regions such as Guangdong, Guangxi, Fujian, Taiwan, Hainan, about 600,000 hectares of cultivated area.On international fruit market, lichee is one of the most competitive minority fruit of China.Along with the raising of China's living standards of the people and the development of international trade, lichee production also can further develop.
Lichee is a typical tropical fruit, special climate condition such as high temperature, rainyly make that the nutrient contents such as the soil organism of main producing region are low, soil is barren, and the fertilizer that applies particularly quick-acting chemical fertilizer also can fall because of a large amount of drip washing of rainfall, causes the low and contaminate environment of utilization rate of fertilizer.According to the study, 1000 kilograms of fruits of every production, 4 kilograms of the mineral element insufficient total amounts of from soil, taking away, and to obtain 1000 kilograms lichee output, the fertilizer nutrient that need use is 40～80 kilograms, this and the many heavy rains in lichee producing region, and quite a few fertilizer is washed away very big relation by rainwater.At present the chemical fertilizer used of lichee mainly is a quick acting fertilizer, in order to reduce fertilizer loss and to satisfy lichee each breeding time of the needs to nutrient, adopts a small amount of fertilization principle repeatedly more, sets fertilising in a year 8～10 times childhood, and many persons reach 20 times.The litchi fertilising is different from general crop, and it need impose on fertilizer the soil layer depths, and this has increased peasant's labour intensity and recruitment cost greatly.Still find no at present the report of composite lichee special-purpose control-release fertilizer and preparation method thereof.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of special controlled-release fertilizer for resin film coated leechee and preparation method thereof, utilize the Nutrient Release of thermoplastic resin membrane wrapping fertilizer, law of nutritive absorption according to lichee carries out single kind controlled release fertilizer and the part quick-acting fertilizer that difference discharges the period composite simultaneously, formed the lichee special-purpose control-release fertilizer, and carried out field experiment, obtained good effect.
Jujube tree special-purpose control-release fertilizer of the present invention, feed composition is as follows by weight:
120～180 parts in 5% thermoplastic resin membrane wrapping saltpetre
220～300 parts in 7% thermoplastic resin membrane wrapping saltpetre

8% thermoplastic resin membrane wrapping urea is meant that the coating layer quality is 8% of a total mass, and product type is KTP06 (43-0-0);
Above raw material produces by Shandong Kingenta Bio-engineering Stock Co., Ltd. and sells, and the numerical value in the product type bracket is the mass percentage content of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide, and being that this area is conventional indicates.Above raw material also can for example can prepare by the method for CN1603288 (200410035783.3) by prior art for preparing.
In the above-mentioned compound potassium sulfate fertilizer, nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide content are respectively 11%～13%, 17%～19%, 14%～16%, further preferred nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide content are respectively 12%, 18%, 15%, are mass percent.
The particle diameter of above-mentioned all raw materials is good in 2～4 millimeters scopes all.
Further preferred, the lichee special-purpose control-release fertilizer, feed composition is as follows, is weight part:
165～175 parts in 5% thermoplastic resin membrane wrapping saltpetre
280～300 parts in 7% thermoplastic resin membrane wrapping saltpetre
50～60 parts in 4% thermoplastic resin membrane wrapping ammonium phosphate

4～6 parts of boraxs.
The preparation method of lichee special-purpose control-release fertilizer of the present invention puts into stirrer together with above-mentioned each raw material and stirred 5～10 minutes, and fully mixing promptly.Then the fertilizer that mixes is sent into metering, wrapping machine measures, packs.
Lichee special-purpose control-release fertilizer of the present invention is once to apply flowering period at lichee; Application process is to dig several long 60～80 centimetres, wide 20～25 centimetres, dark 20～30 centimetres ditches along the tree crown outer, apply fertilizer after earthing pour water.
Excellent results of the present invention is as follows:
1. fertilizer efficiency is steady, be beneficial to the deciduous fruit tree that lichee high and stable yields litchi is different from temperate zone and cool temperature zone, more be different from general annual crop, all be in growth phase its whole year, and in the breeding cycle in 1 year most time be again nourish and grow and reproductive growth go forward side by side, particularly the nitrogen supply is steady and an amount of with regard to the needs nutritive element for this, nitrogen is crossed and was nourished and grown prosperously at most, and influence is bloomed and beared fruit, and the nitrogen deficiency also can make the tree bulk-growth thin and weak, the nutritive substance of making is few, reduces output.Fertile composite the forming rationally of the thermoplastic resin membrane wrapping of the different release periods of special-purpose control-release fertilizer utilization, nutrient supply steadily and sufficient are beneficial to that lichee is nourished and grown and the coordination of reproductive growth, promote stable high yield.
2. the minimizing nutrient loss improves utilization rate of fertilizer lichee producing region high temperature and rainy, adds that the mountain and hill soil layer is thin, quality is thick, and fertilizer-preserving ability is poor, and the quick acting fertilizer that applies runs off with rainwater or irrigation water easily, and fertilizer utilization ratio is low.Special-purpose control-release fertilizer particle outside is surrounded by a skim, and inner nutrient is along with the absorption of root system slowly discharges, and the nutrient ion that retains in the soil is few, with also lacking that rainwater or irrigation water run off, has obviously improved fertilizer utilization ratio.
3. the fertilizer that applies the farmland if preserve the ecological environment can not be absorbed by crop and be lost, and not only wastes resource, increases peasant's production cost, also is a kind of threat to ecotope.Flow into underground water, then pollute human drinking water source, influence people's health.If flow into rivers and lakes, then can eutrophication, reduce the quality of water.Special-purpose control-release fertilizer reduces fertilizer loss, has also just reduced the harm of farmland fertilization to environment from the source.
4. minimizing fertilizer application frequency reduces that the present lichee of peasant's labour intensity is annual to need fertilising 5～10 times, treelet even reach 10～20 times, and need the ditching deep placement, increased peasant's labour intensity greatly.The general annual fertilising of special-purpose control-release fertilizer 1～2 time has alleviated peasant's labour intensity, has saved the recruitment cost, has improved economic benefit.
