Description
Technical field
The present invention relates to a kind of applications of field crop base to exempt from top dressing fertilizer.
Background technique
For a long time, there is very big drawback in conventional composite fertilizer and its method of application.Conventional composite general Nitrogen-and Phosphorus-containing of fertilizer
Potassium nutrition and nutrient content is essentially identical, is not able to satisfy crop to the needs of a variety of nutrition, especially in microelement, Bu Nengyou
For supplement nutrient；Secondly, the nutrient of conventional composite fertilizer is fast-acting type, it is easy to run off early period, later period nutrient is insufficient, the de- fertilizer of crop
It cannot be guaranteed that needs of the crop reproductive growth period to nutrient.In recent years, land transformation aggravates, and traditional base fertilizer adds applying for top dressing
Fertile mode is unable to satisfy large plantation family's demand, and field crop manuring late needs more physical resources and financial resources investments, in labor cost
In the case where the high and shortage of manpower, traditional fertilization is low and a series of problems, such as environmental protection pressure is big there is also utilization rate of fertilizer, hinders
The fast development of agricultural.
At present for conventional composite fertilizer, this season utilization rate of fertilizer only has 30%-40%, compared with conventional composite fertilizer
Novel fertilizer has many advantages.Firstly, the fertilizer efficiency of novel fertilizer is more permanent, it can be up to entire using coated release-controlled technology fertilizer efficiency
Breeding time；Secondly, rationally changing the proportion of nutrient to the needs rule of nutrition according to crop；Meanwhile novel fertilizer addition crop life
Long other middle micronutrients, biological regulator and regulator etc., nutrition more comprehensively, have multiple efficacies.
Novel fertilizer has developed for many years, is also received by wide farmers in actual agricultural production, while more and more
Kind novel fertilizer puts goods on the market, as CN107266269A disclose it is a kind of for rice, the disposable special fertilizer of corn, effective component
There is nitrogen, phosphorus pentoxide, potassium oxide, ureaformaldehyde, nitrification inhibitor, urease inhibitor, plant growth regulator pass through addition urea
Enzyme inhibitor, nitrification inhibitor.By improving the utilization rate of nitrogen, reach single fertilization purpose, it is able to satisfy rice and jade
The nutrient demand of rice entire breeding time does not burn safely root burn seedlings, later period not de- fertilizer early period, but is only applicable to rice and corn.
CN108440054A discloses a kind of fertilizer and preparation method thereof suitable for rice single fertilization, by nitrogenous fertilizer, phosphate fertilizer, potash fertilizer,
Zinc fertilizer is configured to.It is effective to ensure that demand of the growth period duration of rice to nitrogen, avoids burn seedlings early period, later period denitrogenation and nutrient
Unbalanced problem；Enhance the lodging resistance of rice；Single fertilization, cost-saving synergistic improve utilization rate of fertilizer.But it also only
For a kind of crop applying of rice, contained micro-nutrient type is single, and there are short slabs in the nutrition needed for mending water rice.
Summary of the invention
The purpose of the present invention is combined by various aspects, it is desirable to provide one kind is containing there are many Meso- and micro-nutrients, battalion
It supports comprehensive；Nutrient gradually discharges, and fertilizer efficiency is lasting and utilization rate is high, meets the nutritional need of crop entire breeding time；Suitable for water
Top dressing fertilizer is exempted from a variety of field crops such as rice, the field crop base application that whole process only applies disposable fertilizer.
The implementation of the object of the invention is, it is by parts by weight are as follows: urine that top dressing fertilizer is exempted from a kind of field crop base application
25-40 parts plain, 15-20 parts of ammonium chloride, 20-25 parts of phosphate fertilizer, 16-24 parts of potassium chloride, 3-6 parts of granular zinc sulfate, granulated boric fertilizer 1-4
Part, 3-8 parts of siliceous fertilizer, it is other additive 0.02-0.04 parts stir evenly gained fertilizer；
The urea is plain particles urea, the resin coated urea of 30-40 days deenergized period one, 60-70 deenergized period
The mixture of it resin coated urea two and the resin coated urea of 100-120 days deenergized period three, plain particles urea with
The mass ratio of resin coated urea one, two, three is 5:2:1~2:0.5~1；
The phosphate fertilizer is particle Diammonium phosphate (DAP) and particle calcium superphosphate mixture, particle Diammonium phosphate (DAP) and particle calcium superphosphate
Mass ratio be 3:1；
The potassium chloride is the coated with resin potassium chloride of common potassium chloride and 70-90 days deenergized period, and 3:1 in mass ratio is mixed
Mixture made of conjunction；
Other additives are cycocel and the mixture that methyl α-naphthyl acetate 3:1~2 in mass ratio are mixed into.
The present invention has the following advantages:
1, it can be grown for field crop and the big-and-middle microelement such as required nitrogen, phosphorus, potassium, calcium, boron, zinc and grass family work are provided
Element silicon needed for object, nutrition are comprehensive；Slow Controlled Release Nitrogen Fertilizer, potash fertilizer, nutrient gradually discharge, and fertilizer efficiency is lasting and utilization rate is high, meet
The nutritional need of crop entire breeding time；
2, it is excessively prosperous to can be effectively controlled nutrient growth for the additives such as cycocel in raw material, rationally adjusts nutrient allocation, promotees
Into crop reproductive growth；Methyl α-naphthyl acetate can increase rice and wheat effective tillering, improve the percentage of earbearing tiller, promote full seed, and volume increase is aobvious
It writes；
3, base fertilizer use is done, whole process only applies disposable fertilizer, efficiently solves fertilizer application frequency is more, top dressing is difficult, farm work is heavy etc.
Problem, saving of labor, cost-saving synergistic improve utilization rate of fertilizer, reduce agricultural non-point source pollution.
The present invention can be applied to the field crops such as rice, wheat, corn, can significantly improve yield, have section fertilizer volume increase effect
Fruit.
