Abstract
The present invention relates to a controlled-release fertilizer containing multi-humus, which consists of a coating and a fertilizer core. The fertilizer core is formed by mixing urea containing urease inhibitors with humus, wherein the urease inhibitor, the urea and the humus are mixed in ratio of 15-30:100-150:20-45 in parts by weight. The weight of the coating is 7% of that of the core. The controlled-release fertilizer is capable of improving the fertilizer efficiency, alleviating crop diseases, improving the agricultural product quality and increasing both production and income. The controlled-release fertilizer changes the traditional fertilizing mode so that most crops only need to be fertilized once, and thereby reducing the fertilizing amount and frequency, and saving cost, time and labor.
Description
Technical field
The present invention relates to a kind of fertilizer, especially relate to a kind of release and release control fertilizer that contains various nutrient elements such as soil ulmin and preparation method thereof.
Background technology
China is large agricultural country, because long-term a large amount of use of traditional chemical fertilizer causes soil that certain single nutrient demand is constantly increased, rate of fertilizer application is strengthened, and has increased agriculture production cost, and Soil structure is damaged, and the quality of agricultural-food descends.In addition, traditional chemical fertilizer nutrient effective rate of utilization is low, and life-time service not only causes a large amount of losses of fertilizer nutrient.Disastrous effects such as even more serious is uses in a large number for a long time that traditional chemical fertilizer has caused that groundwater azotate content improves, water body in lake eutrophication and atmosphere Greenhouse effect are serious day by day.And release and release control fertilizer have improve chemical fertilizer utilization ratio, reduce usage quantity and fertilizer application frequency, reduce production costs, reduce environmental pollution, advantage such as raising crop products quality.Promote controlled release fertilizer Economic development, energy-saving and emission-reduction, environment protection etc. are all had significance.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of release and release control fertilizer that contains multiple soil ulmin and preparation method thereof.
In order to solve the problem that prior art exists, the technical solution used in the present invention is:
A kind of release and release control fertilizer that contains multiple soil ulmin is made up of coating and fertile core, and described fertile core is to contain the urea of urease inhibitor and the mixture of soil ulmin, and coating is 7% of a fertile core weight.
Described fertile core is made of according to the following number of weight ratio following component:
Urease inhibitor: urea: soil ulmin=15-30: 100-150: 20-45.
Described urease inhibitor is a N-acetylhydroxylamine.
Described a kind of preparation method who contains the release and release control fertilizer of multiple soil ulmin may further comprise the steps:
1. according to urease inhibitor: the ratio of urea: soil ulmin=15-30: 100-150: 20-45 is got the above-mentioned raw materials thorough mixing and is evenly made fertile core;
2. the outside surface whitewashing bag at fertile core is formed coating.
Advantage and effect that the present invention had are:
A kind of release and release control fertilizer that contains multiple soil ulmin of the present invention can improve the fertilizer efficiency utilization ratio.It has the slow release long-acting effect, and fertilizer nutrient discharges in soil slowly, reduces nutrient loss, can continuously supply with plant the whole growth phase to nutrient demand, improved the fertilizer efficiency utilization ratio.Have test to show: controlled release fertilizer can double utilization rate of fertilizer by original 35% about, the loss of nitrogenous fertilizer rate significantly reduces, and can save nitrogen fertilizer amount 30%-50%.The 2nd,, can alleviate corps diseases and improve quality of agricultural product, promote increasing both production and income.Corps diseases is relevant with nitrogen fertilizer amount with product quality, uses slow-release or control-release fertilizer and can prevent the excessive absorption of farm crop to nitrogen, thereby play the effect that suppresses disease and improve quality.Simultaneously, discharge, make the crop nutrition content supply steadily regular, avoid crop to take off fertilizer and excessive growth, promote increasing both production and income by coating control nutrient.The 3rd,, save cost, time saving and energy saving.Release and release control fertilizer can change traditional fertilization mode, most of crop can realize one season crop only execute disposable fertilizer, reduced the quantity and the number of times of fertilising, save cost, time saving and energy saving cutting the waste.Fertile core of the present invention is owing to added soil ulmin, and soil ulmin decomposes in soil under certain condition lentamente, discharges based on the nutrient of nitrogen and sulphur and supplies with plant absorbing, emits carbonic acid gas simultaneously and strengthens photosynthesis of plants.Soil ulmin has adsorption to the heavy metal in the soil and some objectionable impuritiess simultaneously
