Abstract
The present invention discloses a multifunction fertilizer proportionally prepared by using low salt index fertilizers, such as cyanogen calcium nitride (lime nitrogen), calcium superphosphate, a calcium magnesia phosphate fertilizer, potassium sulfate, etc., without acid radicals, and the fertilizers can decompose sterilized substances without residual toxicity after the fertilizers are applied into soil. The multifunction fertilizer has the advantages of convenient use, soil acidification correction, salinization prevention, soil nitrifying bacterium activity inhibition, and fertilizer effect enhancement. The multifunction fertilizer can effectively kill soil fungi and prevent vegetable fungal diseases from occurring after applied to a continuous cropping vegetable plot at one time. The multifunction fertilizer which is a multifunction special vegetable fertilizer for correcting and overcoming the continuous cropping obstacle of vegetable production is suitable for application in vegetable continuous cropping areas.
Description
Technical field
The invention belongs to the extraordinary technical field of fertilizers of fertilizer, agricultural chemicals dual-purpose, especially belong to a kind of fertilizer special for vegetable material and the application method thereof rescuing and overcome vegetables production continuous cropping obstacle.
Background technology
The continuous cropping obstacle problem of vegetable crop intensifies day by day, has become a great problem in the present agriculture production, especially melon, solanberry class, and continuous cropping obstacle is very general, has greatly restricted production and the development of these vegetables.According to research reports, continuous cropping obstacle mainly is because the increase of disease and pest and long-term continuous cropping cause that nutrient imbalance and improper fertilization cause that soil acidification, soil salt gather etc., causes the plant physiology obstacle to cause.Usually adopt soil disinfection, rice field-upland field rotation, inhomogeneity vegetable crop rotation and the measures such as resistant variety or resistance stock of using to prevent and treat, for example avoid same class vegetable continuous cropping in order to avoid cause single-minded venereal disease worm, especially the serious harm of soil fungi; Adopt waterflooding, deep ploughing, improvement fertilising, plantation to subtract measures such as salt crop (as gramineous crop), organic fertilizer and alleviate gathering of salt in the soil; Measures such as employing fertilization compositions based on earth measurement are made the inorganic elements equilibrated up and are destroyed.But above measure is for the vegetables grown place, and especially carry out the rice field-upland field rotation meeting to make the household economy benefit be subjected to great restriction, and often desalination are not thorough in production base of outskirts of a town special vegetable and protection facilities vegetable base etc.; Though it is good to wait bitterly for sterilising effect with steam sterilizing or chlorination, cost is too high and have safety and environmental pollution hidden danger; It is very inconvenient, time-consuming that the while producer generally feels to implement above-mentioned measures separately, and effect is also undesirable; Therefore, in time solve this difficult problem and become instant task of agri-scientific research worker.
Summary of the invention
The objective of the invention is deficiency, propose a kind of have soil sterilization sterilization, acid, the minimizing salt accumulation of neutralization, the comprehensive fertilizer special for vegetable of rescuing and overcoming vegetables production continuous cropping obstacle at above existence; Another object of the present invention is clear and definite effective using method of this fertilizer in different properties soil.
Principle of the present invention is to start with from fertilising, in conjunction with surveying soil metering rational application of fertilizers technology, the no acid group nitrogenous fertilizer lime nitrogen with soil disinfection effect that can decompose no residual hazard after selecting low salt index phosphorus potash fertilizer and soil to execute is a raw material, be mixed be fertilizer again tool rescue and overcome the fertilizer special for vegetable of the many obstacles of vegetables production continuous cropping, produce to ensure the vegetables safe and continuous.
The present invention is achieved by the following technical programs:
A kind of fertilizer, by following component and formulated granule or the pulvis of weight percent content:
Calcium cyanamide 50～60%
Calcium superphosphate 15～30%
Fused(calcium magnesium)phosphate 0～10%
Vitriolate of tartar 10～20%
Prescription when wherein, this fertilizer is used for acid soil is:
Calcium cyanamide 50%
Calcium superphosphate 20%
Fused(calcium magnesium)phosphate 10%
Vitriolate of tartar 20%
Prescription when this fertilizer is used for neutrality or alkaline soil is:
Calcium cyanamide 60%
Calcium superphosphate 30%
Vitriolate of tartar 10%
The manufacture method of this fertilizer is, said components in proportion weighing mix the cooling back pulvis, or through the Squeezinggranulator granulation granule.
The concrete application method of described fertilizer is to carry out according to the following steps:
(1), according to using plot soil acid-base reaction, selection mugineic acid or neutrality, the made fertilizer of alkalescence prescription;
(2), use preceding field piece and perform furrow, pouring water turns over rakes, and keeps water layer 1～3cm, it is dried to allow water fall naturally, note not allowing rich water flow near the field piece, in order to avoid the field piece is done deposits yields fertilizer damage, poisoning near causing;
(3), amount of application is per hectare 1500～2250kg;
(4), use after 15 days in conjunction with sowing or transplanting seedlings, water root with the beneficial microorganism microbial inoculum, or use the organic fertilizer that is connected to the beneficial microorganism bacterial classification.
The beneficial effect of fertilizer of the present invention is:
(1) suppresses soil nitrification bacterium vigor, improve effect of fertilizer: calcium cyanamide is a kind of no acid group alkaline fertilizer, use the back when soil moisture is sufficient, can decompose generation urea fully about 7～10 days, be decomposed into bicarbonate of ammonia at last, product cyanamide or Dyhard RU 100 have very strong restraining effect to nitrobacteria activity in the soil in the middle of it, therefore, nitrogen in this fertilizer is based on ammonia-state nitrogen, and is difficult for changing into nitric nitrogen, longly is difficult for running off so hold to imitate in soil;
(2) effectively eliminate soil fungi, restrain the generation of vegetable fungi disease: fertilizer of the present invention is in manufacturing processed, calcium cyanamide is with after calcium superphosphate mixes, with a spot of free-water in the calcium superphosphate as medium, produce the hydrolysis reaction of acid-base neutralisation reaction and calcium cyanamide, generated a certain amount of cyanamide, these cyanamides of back that are manured into soil can produce restraining effect to the pathogenic bacteria in the soil at once, this fertilizer can decompose the more cyanamide of generation run into adequate water in soil after simultaneously, add the calcium oxide sterilization component that calcium cyanamide itself contains, thereby fungi there is strong killing action, disease suppresses effect very good (seeing embodiment), can break the silborne fungal diseases obstacle that is caused by continuous cropping;
(3) correct soil acidification, prevent salinification: calcium cyanamide is a kind of no acid group alkaline fertilizer, can correct soil acidification in soil, and can not cause electricity to lead rising; The salt index of calcium superphosphate, vitriolate of tartar is also lower, therefore, uses fertilizer of the present invention can alleviate the soil secondary salinization that fertilising causes;
(4) easy to use, remarkable in economical benefits: fertilizer of the present invention only need once apply in the soil, can reach sterilization and disinfection, corrects soil acidification, prevents salinization, overcome the vegetable plot continuous cropping obstacle, obtains the effect of increasing both production and income 40%.
