Description
Technical field
The present invention relates to a kind of method of utilizing the crop special-purpose control-release fertilizer of thermoplastic resin membrane wrapping production, relate in particular to a kind of special control-release fertilizer for resin coated bagasse and preparation method thereof, belong to slow/controlled release fertilizer technology field.
Background technology
Sugarcane is important sugar raw materials for production, and whole world sugar ultimate production was 1.456 hundred million tons in 2003, wherein be with the sugarcane raw material account for 70%.China is important sucrose producing country, and sugarcane acreage was 121 hectares in 2002, occupied the third place in the world.Sugarcane still is a kind of bioenergy crop of high yield, its biological yield height, and the sugar degree height not only can be for sugaring, but direct production alcohol also.Along with the continuous development of science and technology, as the important energy crop, sugarcane has very big development potentiality.
The saccharum torrid zone and subtropical crop have the advantages that water requirement is big, suction fertilizer is many, vegetative period is long.The length in the yield and quality of sugarcane and the rational application of fertilizer and vegetative period has much relations, and in order to prolong the evaporation of growth time and minimizing soil moisture, cultivation of sugar cane is being promoted film-mulching technique, and this has just brought certain degree of difficulty for fertilising.The fertilizer of using at present mainly is the quick-acting chemical fertilizer, their dissolvings are fast, if before plantation, once a large amount of fertilizer is applied near the root district, can cause that nutrient density is too high in the soil solution, " burning root " phenomenon appears, also can aggravate soil simultaneously to nutrient ionic fixed action, make nutrient lose validity, reduce utilization rate of fertilizer sugarcane.If adopt a small amount of fertilizing method repeatedly, then can destroy mulch film, make it ineffective.The report that sugarcane special-purpose control-release fertilizer and preparation method thereof is not arranged at present as yet.
For this reason, we utilize the Nutrient Release of thermoplastic resin membrane wrapping saltpetre, thermoplastic resin membrane wrapping ammonium phosphate and thermoplastic resin membrane wrapping urea controlled release fertilizer, while is according to the law of nutritive absorption of sugarcane, the single kind controlled release fertilizer and the part quick-acting fertilizer that difference are discharged the period carry out composite, formed the sugarcane special-purpose control-release fertilizer, and carried out field experiment, obtained good effect.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of special control-release fertilizer for resin coated bagasse and preparation method thereof, utilize the Nutrient Release of thermoplastic resin membrane wrapping fertilizer, law of nutritive absorption according to sugarcane carries out single kind controlled release fertilizer and the part quick-acting fertilizer that difference discharges the period composite simultaneously, formed the sugarcane special-purpose control-release fertilizer, and carried out field experiment, obtained good effect.
Sugarcane special-purpose control-release fertilizer of the present invention, feed composition is as follows by weight:

The preparation method of sugarcane 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.
Sugarcane special-purpose control-release fertilizer of the present invention is to make base manure once to apply before the sugarcane sowing; No longer impose.
Excellent results of the present invention is as follows:
Nutrient element releasing rule meet sugarcane high yield and high quality needs sugarcane be with results terrestrial stem be the crop of product, nitrogen, phosphorus, three kinds of main nutrient elements of potassium have different effects to the yield and quality of sugarcane.Nitrogen promotes the cauline leaf growth, and mid-early stage needs more, and the later stage should suitably be controlled, in order to avoid sugar degree remaining green when it is due to become yellow and ripe and reduction sugarcane stem; Phosphorus have and is beneficial to root system and yielding positive results, and should increase consumption in earlier stage, and control in mid-term prevents that reproductive growth from crossing Sheng; The plain transfer that strengthens the lodging tolerance of stem and promote the leaf photosynthesis product of potassium, the growth middle and later periods needs more.Special-purpose control-release fertilizer designs according to these rules just, can satisfy sugarcane high yield and high quality needs.
2. be suitable for advanced cultivation techniques such as membrane covering, the cultivation technique that the horizontal sugarcane membrane covering of the raising overall cultivation of sugarcane is an advanced person, it can make the sowing time in advance, improves output by prolonging growth time; Reduce simultaneously soil water evaporation again, improve the utilization ratio of water.But this technology has also been brought inconvenience for fertilising.Special-purpose control-release fertilizer once applies before adopting sowing, no longer topdresses later on, has avoided contradiction between the two.
3. raising utilization rate of fertilizer special-purpose control-release fertilizer is concentrated and is executed in sugarcane root district, has increased the contact area of fertilizer and root system, is convenient to absorb, and has improved utilization rate of fertilizer.Result of study shows that under the same amount condition, special-purpose control-release fertilizer increases operation rate 10%～30% than common chemical fertilizer.
4. the minimizing fertilizer application frequency reduces peasant's labour intensity generally speaking, and sugarcane is except that using base manure, need topdress 2～3 times, special-purpose control-release fertilizer is made the base manure applied once prior to seeding, no longer topdresses later on, reduce fertilizer application frequency, reduced peasant's labour intensity, saved the recruitment cost.
