The organic fertilizer is added to the chloride-based slow-release compound fertilizer, and the organic fertilizer is rich in humic acid, which can improve the soil structure, is the catalytic agent and irritating agent for crop growth; the organic fertilizer can also activate nutrient, increase the contents of the available nitrogen, phosphorus and potassium in the soil, and improve the ratio of solid phase, liquid phase and gas phase in the soil; and the fertilizer use efficiency is improved, the agricultural non-point source pollution is reduced, the stress resistance of plants is enhanced, and the crop quality is improved.
Description
Technical field
The invention belongs to field of fertilizer production, relate to a kind of chloride-based slow-release complex fertilizer and production technique thereof.
Background technology
China's chemical fertilizer consumption amount accounts for the 20-30% of world Fertilizer total quantity consumed, ranks first in the world, and the chemical fertilizer this season utilization ratio average out to 50-60% of developed country, and China's chemical fertilizer this season utilization ratio on average is merely 30-35%.The loss waste of macronutrient not only brings enormous economic loss to society, but also can cause serious environmental to pollute.Improve utilization rate of fertilizer, reduce dose, save the fertilising labor force; Seem particularly important; Slow/controlled release fertilizer makes it to absorb basic synchronised with crop nutrition content through the regulation and control to the nutrient release rate, can improve the fertilizer nutrient utilization ratio greatly, reduces widespread pollution from the overuse of fertilizers and pesticides in rural area; Meet the requirement of national sustainable development strategy, so sustained-controll-release fertiliser has become one of main direction of 21 century fertilizer industry development.
At present; The research of organic polymer coating controlled-release fertilizer has both at home and abroad developed into a higher height; Technology reaches its maturity; The nutrient controlled release properties is good, and the problem that production cost is high has obtained preliminary solution, but waits further to reduce production costs apart from its widespread usage on field crop; The sulfur coated fertilizer price is lower, but this technology can reduce the nutrient content of macroelement greatly, makes the fertilizer total nutrient on the low side; Urease inhibitor and nitrification inhibitor equistability fertilizer can not satisfy the requirement of slow controlled release properties; And have the problem that blending is inhomogeneous, use inconvenience, therefore develop a kind of sustained-controll-release fertiliser of using conveniently, being fit to the field crop popularization and have important practical significance.
Authorize Chinese patent document (application number: 200810139378.4, Granted publication CN 100548935C) to disclose a kind of sustained-release adhesive and preparation method thereof.This sustained-release adhesive is made at 75-80 ℃ of following stirring reaction by urea, 37% formaldehyde, Sumstar 190, wherein the mol ratio 1.2-1.6 of urea and formaldehyde: 1, and Sumstar 190 is with being most the heavy 8-10% of urea.This sustained-release adhesive can solve common composite fertilizer nutrient and discharge problems such as too fast, that the product hardness outward appearance is undesirable.
Summary of the invention
To the deficiency of prior art, the purpose of this invention is to provide a kind of chloride-based slow-release complex fertilizer and production technique thereof, satisfy the demand of field crop to the slow controlled release properties of nutrient.
