The soil improvement type rape Special slow release fertilizer that the preparation method of a kind of soil improvement type rape Special slow release fertilizer that adopts the present invention to propose makes is contrasted after using impact and conventional fertilizer aspect soil physical and chemical property, yield of rape and economic benefit thereof after using, and sees the following form 1, table 2, table 3.
Table 1 soil improvement contrast
Table 2: yield comparison
Table 3 economic efficiency contrast
In the present invention, the soil improvement type rape Special slow release fertilizer of described preparation contains the necessary macroelement of growth of rape such as abundant nitrogen, phosphorus, potassium, science has been added the Meso-and micro-nutrients such as calcium, magnesium, boron simultaneously, make rape to the absorption of nutrient general equilibrium more, be conducive to strengthen photosynthesis and the drought resisting disease and insect resistance lodging tolerance of rape, improve the quality and yield of rape; This product can slowly discharge nutritive element enduringly in conjunction with growth characteristics and the regulation of fertilizer requirement of rape, effective release period of nutrient in fertilizer is extended, thereby meet the demand of growth of rape middle and later periods for nutrient, avoids early ageing and de-fertile; This product can meet the rape whole breeding time of the demand to nutrient as disposable the applying of base manure, compares the conventional fertilizer of application, within the whole breeding time of rape, apply fertilizer 3～4 times even more, there is the saving of labor, save time and improve the advantages such as utilization rate of fertilizer; This product has improvement and fertilization effect to soil, main manifestations is for reducing the soil weight, increase soil permeability, reduce or improve soil acidity or alkalinity, increase soil organic matter content, can reduce soil to phosphorus fixation, increase the movement of phosphorus in soil and stimulate the absorption of crop to phosphorus, reduce the probability that potassium ion is fixed by lattice, extend the fertilizer efficiency of potassium.Soil improvement type rape Special slow release fertilizer prepared by the present invention is applicable to rapeseed cultivation on the obstacle soil such as China's rape producing region and acid-alkali salt and uses.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
