Abstract
The invention relates to a fertilizer and a fertilization method thereof, in particular to a soybean combined fertilizer and a fertilization method thereof, solving the problems of unreasonable nitrogen-phosphate collocation, high fertilizer cost, low phosphate fertilizer utilization rate and low soybean yield existed in the prior soybean fertilizer fertilization method. The soybean combined fertilizer comprises 80kg to 120kg of diammonium phosphate, 10kg to 20kg of common urea and 40kg to 50kg of slow-release urea. The fertilization method comprises: the soybean combined fertilizer is once fully fertilized in farmland, and the fertilization is finished. The fertilization method of the special soybean fertilizer reduces the consumption of phosphate fertilizer, decreases the fertilization cost, improves the soybean yield, improves the economic benefits, has simple operation and is convenient to popularize and apply.
Description
Technical field
The present invention relates to a kind of fertilizer and fertilizing method thereof.
Background technology
Soybean is the crop that root nodule bacterium fixed nitrogen is arranged self, for a long time, compares people with nitrogenous fertilizer and lays particular stress on and look using of phosphate fertilizer.But utilization ratio is low, the longevity of residure long because phosphate fertilizer has then, accumulate in soil, uses phosphate fertilizer in the production in a large number year after year, and long-term accumulation makes soil quick-effective phosphor content rise significantly.The fertilizer effect test-results shows that the effect of increasing production that phosphate fertilizer is used in the farmland obviously reduces; Soybean needs nitrogen more, but owing to itself nodule nitrogen fixation is arranged, makes nitrogen application become very complicated.Execute nitrogen and should satisfy soybean in earlier stage to the needs of nitrogen, also will guarantee has enough nitrogen to supply with in the soil of root nodule decline back.Soybean needs competent nitrogenous fertilizer to supply with could obtain higher output.Traditional fertilization can only satisfy soybean fertility nitrogenous fertilizer supply in early stage, and can't guarantee the nitrogenous fertilizer demand of soybean late growth stage, takes the later stage to impose nitrogenous fertilizer in the production, and the difficulty of topdressing is bigger, has increased a large amount of artificial inputs again.Therefore, traditional NP proportioning, amount of application and fertilizing method have caused the fertilizer cost height, and phosphate fertilizer utilization efficiency is low, the problem that soybean yields is low.
Summary of the invention
The present invention seeks to have the problem that the collocation of nitrogen phosphorus is unreasonable, fertilizer cost is high, the difficulty of topdressing is big, phosphate fertilizer utilization efficiency is low, soybean yields is low, and a kind of soybean combined fertilizer and fertilizing method thereof are provided in order to solve existing soybean fertilizer fertilizing method.
To achieve these goals, the technical scheme taked of the present invention is:
Soybean combined fertilizer is made up of diammonium phosphate 80～120kg, common urea 10～20kg and slow-release carbamide 40～50kg.
Soybean combined fertilizer is used by the following method: soybean combined fertilizer per hectare amount of application is 130～190kg; Puddle evenly by per hectare diammonium phosphate 80～120kg, common urea 10～20kg, slow-release carbamide 40～50kg, apply in the farmland with the disposable full dose layering of seed sower during soybean planting, i.e. fertilising is finished.
The invention has the beneficial effects as follows: the resulting soybean combined fertilizer of the present invention has reduced the consumption of phosphate fertilizer (diammonium phosphate) according to application process of the present invention, suitable increase nitrogen fertilizer amount (urea and slow-release carbamide), improved the utilization ratio of phosphate fertilizer like this, reduced the cost (per hectare reduces 100～150 yuan of fertilizer costs) of fertilising significantly, having improved the output of soybean, (output is 2900～3100kg/hm
2, stimulation ratio is 20.4%～23.6%), also improved peasant's economic benefit accordingly.The present invention is simple to operate, and is easy to utilize.
Embodiment
Technical solution of the present invention is not limited to following cited embodiment, also comprises the arbitrary combination between each embodiment.
Embodiment one: the present embodiment soybean combined fertilizer is made up of diammonium phosphate 80～120kg, common urea 10～20kg and slow-release carbamide 40～50kg.
Embodiment two: what present embodiment and embodiment one were different is that soybean combined fertilizer is made up of diammonium phosphate 90～110kg, common urea 12～18kg and slow-release carbamide 42～48kg.
Embodiment three: what present embodiment and embodiment one were different is that soybean combined fertilizer is made up of diammonium phosphate 100kg, common urea 15kg and slow-release carbamide 45kg.
Embodiment four: the present embodiment soybean combined fertilizer is used by the following method: soybean combined fertilizer per hectare amount of application is 130～190kg; Puddle evenly by per hectare diammonium phosphate 80～120kg, common urea 10～20kg, slow-release carbamide 40～50kg, apply in the farmland with the disposable full dose layering of seed sower during soybean planting, i.e. fertilising is finished.
In the present embodiment when soybean planting to the disposable employed soybean combined fertilizer of soybean, both satisfied needs in soybean early stage to nitrogen, guarantee the nitrogenous fertilizer demand of soybean late growth stage (bloom and bear pods-rouse a phase) again.
Embodiment five: what present embodiment and embodiment four were different is that soybean combined fertilizer per hectare amount of application is 140～180kg.Other step and parameter are identical with embodiment four.
Embodiment six: what present embodiment and embodiment four were different is that soybean combined fertilizer per hectare amount of application is 160kg.Other step and parameter are identical with embodiment four.
Embodiment seven: the present embodiment soybean combined fertilizer is used according to the following steps: soybean combined fertilizer per hectare amount of application is 160kg, be that per hectare diammonium phosphate 100kg, common urea 15kg, slow-release carbamide 45kg puddle evenly, use present soybean to produce and go up double row sowing machine on the widely used 2BT-2 ridge, disposable full dose layer by layer manuring is in the farmland in the time of sowing, i.e. fertilising is finished.
2008, adopt the fertilizing method of present embodiment to carry out the output test in Heilongjiang Province's Hailun City township that advances, sowing on May 4, soybean varieties is black farming 35.Type of seeding: use double row sowing machine on the 2BT-2 ridge, the ridge of 67cm, double row sowing on the ridge, per hectare 250,000 strains of keeping a full stand of seedings.Fertilizing method: carry out according to present embodiment, conventional chemical sealing weeding, three intertillages, the soybean yields that obtains has reached 2945kg/hm
2, than conventional fertilizer application field volume increase 21.1%.
