Description
Technical field
The invention belongs to vegetable fertilizer technical field, be specifically related to the preparation method of a kind of vegetables slow-release compound fertilizer.
Background technology
The reasonable employment of fertilizer is not only closely bound up with the yield of agricultural product, and the quality safety concerning agricultural product is asked
Can topic, reasonable employment fertilizer be the key that high quality agricultural products produces.Practice have shown that, the most directly effectively improve the hand of crop yield
Section is rationally to enrich fertilizer, and this also adjusts the most important means of farmland ecosystem balance and Nutrient Cycling.
China's fertilizer application is inefficient, and by the statistics display of a large amount of field test data, China's utilization rate of nitrogen fertilizer is 30
～35%, fertilizer be 10～20%, potash fertilizer be 35～50%.This has the gap determining degree compared with developed countries.Not only
Cause the waste of resource, and enormous pressure can be caused to ecological environment.
The features such as the nutritive peculiarity of vegetable crop is embodied in that root system is shallow, likes high rich water, weak, the luxury absorption of absorbability.Cause
This vegetable crop vegetable plot dose, fertilizer requirement is of a relatively high.In recent years, many vegetable growers are for obtaining maximum economic well-being of workers and staff, pass through
Chemical fertilizer is excessive to be put into pursue the high yield vegetables, and its result often leads to vegetable increase production amplitude and declines year by year, reduces fertilizer
Utilization rate and be not reaching to higher economic benefit, vegetable flavor and quality decline, even severe contamination environment, causes vegetable plot
The even more serious problem such as soil degradation, wherein nitrogen is particularly problematic.Therefore, in order to realize high yield that vegetables produce, excellent
Produce, safety nuisance free reaches sustainable development, it is necessary to studies further for the vegetable plot rational application of fertilizer and includes novel fertilizer
The research and development of material.Slow-release or control-release fertilizer has the important function improving fertilizer utilization efficiency, reducing environmental pollution, and it can realize nutrients release
With Crop synchronization, reduction field ammonia volatilization amount.Numerous studies show, it is excellent that slow-release or control-release fertilizer can not only make crop reach high yield
Produce, and can also reduce labour base fertilising material and topdress input, use less fertilizer amount to carry nitrogen fertilizer use simultaneously
Rate, reduces the pressure bringing environment.
