Abstract
The present invention discloses a kind of radish soil testing and formulated fertilization method.Current peasant applies fertilizer and mainly relies on chemical fertilizer with planting, and result causes soil to harden in a large number, and crop yield and quality reduce, and causes the environmental problems such as loss of soil nutrient, unbalance, pollution of area source and soil acidification simultaneously.The present invention is based on soil testing and manuring field trial, according to radish regulation of fertilizer requirement, fertilizer provision from soil performance and fertilizer effect, on the basis of Rational Application organic manure, what propose the fertilizer such as nitrogen, phosphorus, potassium and middle and trace element uses quantity, fertilizing time and application process.The growth rhythm that soil testing and formulated fertilization method makes full use of radish is implemented to apply fertilizers scientifically, and improves utilization rate of fertilizer, increases soil fertility, reduces the soil pollution that improper fertilization brings, improves the ecological environment, and effectively improves radish yield and economic benefit.
Description
Technical field
The present invention relates to a kind of radish soil testing and formulated fertilization method, particularly relate to a kind of method of carrying out rational application of fertilizers according to soil nutrient, belong to agricultural fertilizer technical field.
Background technology
The annual chemical fertilizer utilization ratio of current China is on average only 30%, and the availability of nitrogenous fertilizer is generally 30% ~ 50%, and the availability of phosphate fertilizer is generally 10% ~ 15%, and the availability of potash fertilizer is generally 40% ~ 70%.The reason causing chemical fertilizer utilization ratio on the low side is a lot, fertilizing amount and Application Ratio unreasonable be principal element wherein.By carrying out fertilization compositions based on earth measurement, reasonably can determine each nutritive element ratio in fertilizing amount and fertilizer, effectively improving chemical fertilizer utilization ratio.Reduce the soil pollution that improper fertilization brings, improve the ecological environment, effectively improve radish yield and economic benefit.
Summary of the invention
The object of the invention is the deficiency in order to overcome above-mentioned technology, a kind of soil testing and formulated fertilization method is provided, by surveying soil formula, under fully understanding soil fertility situation, according to radish regulation of fertilizer requirement, fertilizer provision from soil performance and fertilizer effect, what propose the fertilizer such as nitrogen, phosphorus, potassium and middle and trace element uses quantity, fertilizing time and application process.
The present invention is based on soil testing and manuring field trial, according to radish regulation of fertilizer requirement, fertilizer provision from soil performance and fertilizer effect, on the basis of Rational Application organic manure, what propose the fertilizer such as nitrogen, phosphorus, potassium and middle and trace element uses quantity, fertilizing time and application process.This fertilizing method improves utilization rate of fertilizer, increases soil fertility, reduces the soil pollution that improper fertilization brings, improves the ecological environment, and effectively improves radish yield and economic benefit.
Implementation step of the present invention is as follows:
1, soil nutrient detects
1) sample
Choose block area be 2-3 mu radish ground, by sawtooth pattern or snake type be evenly distributed and random selecting 15-20 put sample, the sampling soil degree of depth is 0-30 centimetre.
2) detect
Soil specimen is air-dry, carry out pre-treatment, detect soil nutrient, measure soil acidity or alkalinity, organic matter, available nitrogen, available phosphorus, available potassium and middle and trace element, to obtain test value;
2, fertilizer formula
According to soil specimen nutrient testing result and the related soil criteria for classifying, determine this plot soil fertility, determine target output, again in conjunction with radish growth demand, determine the nutrient required for radish, then determine fertilizer formula by calculating, carry out proportioning by available N and P, potassium content and apply fertilizer.
3, fertilizing method
Adopt above-mentioned formula fertilizer, yield level, can nitrogen fertilizer application (N) 15-20 kg/acre, phosphate fertilizer (P at 4500-5000 kg/acre
2o
5) 5-8 kg/acre, potash fertilizer (K
2o) 12-14 kg/acre; Yield level at 3000-3500 kg/acre, nitrogen fertilizer application (N) 10-13 kg/acre, phosphate fertilizer (P
2o
5) 4-6 kg/acre, potash fertilizer (K
2o) 10-12 kg/acre; Yield level 1500-2000 kg/acre, can nitrogen fertilizer application (N) 6-9 kg/acre, phosphate fertilizer (P
2o
5) 3-5 kg/acre, potash fertilizer (K
2o) 8-10 kg/acre.Nitrogen, potash fertilizer divide base manure and secondary to topdress, and phosphate fertilizer all makes base manure, and nitrogen, potash fertilizer base manure sowing amount are the 1/2-2/3 of its total amount.Topdress and expand early stage and fleshy root at fleshy root and expand and use mid-term.For improving radish fleshy root yield and quality, in the radish growth middle and later periods, can in conjunction with top dressing, the nitrate of lime with 0.3% and 0.2% boric acid foliage-spray 2-3 time, in case calcium deficiency, boron deficiency.
Beneficial effect of the present invention:
Fertilization compositions based on earth measurement is compared with common fertilizing method, improves utilization rate of fertilizer, has cultivated soil fertility, and increase nutrient, decreasing pollution, improves the ecological environment, and improves crop yield and quality.
Embodiment
A kind of radish soil testing and formulated fertilization method of the present invention, is described in further detail in conjunction with embodiment below:
Embodiment 1
For somewhere plantation radish, cultivated area is two mu.
