Abstract
The invention is a producing method of new slow-release nitrogen fertilizer by the use of a biological engineering material PAL, which makes full use of PAL lays, chains and fibrous crystal structures, nano-aperture access, the microcosmic structural characteristics of large specific surface area and strong adsorption, and good nature of ion exchange, to greatly enhance the sustained-release function through molecular reaming technology and activation process. The slow-release nitrogen fertilizer from PAL material can control the release rate of organics and different ions according to different pH of soil, to hold and save fertilizer for a long term, significantly reduce pollution to the agricultural ecological environment, promote root growth and activity, and significantly improve quality and yield of crops. It has a wide range of application in agricultural production and agro-ecosystems.
Description
Technical field:
The present invention relates to the physical characteristics of a kind of PAL of utilization material (its raw material is a polygorskite, through the ultramicronising purification processes, polygorskite purity＞90%, particle diameter＜8 μ) self, satisfied slow release, improved the chemical fertilizer effective rate of utilization fertilizer.The feature of the layer of PAL material, chain, fibrous crystals structure and nano level hole passage microtexture, make the PAL material have very big specific surface area, after molecule reaming, activation, make it have very strong adsorptive power, possessed the necessary sustained release performance advantage of slow-release nitrogen fertilizer.
Background technology:
At present, in the chemical fertilizer field, the starting material that are used for preparing nitrogenous fertilizer are more, be rich in required various trace elements of plant and specific surface area is big, adsorptivity is strong physical features but utilization PAL material is this, use the slowly-releasing principle of dynamics, be applied to the slow-release nitrogen fertilizer that preparation (production) has slow-release function, still belong to the first time.
Summary of the invention:
Main purpose of the present invention is:
Utilize the performance advantage such as characteristic resources-distinctive adsorptivity of PAL material, slow-releasing of our province, be applied to preparation (production) slow-release nitrogen fertilizer, reduce fertilizer amount, improve chemical fertilizer utilization ratio, the PAL material is played a positive role in China's agriculture production, optimization agroecological environment.
Specific embodiments:
PAL material raw ore is the granular powder of 60-200 purpose through pulverizing, purify, screening, after the nitrogenous fertilizer of assembly same ratio, phosphorus, potash fertilizer and water, the mixing and stirring, dries, be a granulated into 20-200 order shape, can make slow-release nitrogen fertilizer.In the making processes of the present invention, do not produce waste, no chemical pollution, product application has environment-friendly advantage, and slow releasing function is obvious, can optimize agroecological environment greatly.
Claims (3)
1, a kind of method for preparing new sustained release nitrogenous fertilizer with PAL material (its raw material is a polygorskite, through the ultramicronising purification processes, polygorskite purity＞90%, particle diameter＜8 μ).
2, according to claim 1, the PAL material feedstock is crushed to 60 to 200 order powders, purify through the high speed centrifugation purifying technique, by the PAL powder: 8% phosphoric acid dilute solution=1: 1.2 is carried out immersion in 24 hours.Treated PAL material is because of its constitutional features tool slow-releasing.
3, method according to claim 1, PAL powder after soaking and nitrogenous fertilizer (urea) are fully stirred, dry after in ratio assembly in 6: 4, make 20-200 order granular solids material, be slow-release nitrogen fertilizer, it is characterized by and utilize its slow-release capability principle, fertilizer is slowly discharged, the crop absorbing power is strengthened, fertilizer utilization ratio improves.
