Abstract
An agricultural composite material for saving and slowly releasing water in order to regulate the content of water in soil is prepared from nutritive liquid, special fertilizer for particular crops, degradable material, and high-molecular material for absorbing the excessive water from water and slowly releasing water to dry soil.
Description
Affiliated technical field the present invention relates to a kind of agricultural water-saving slow-releasing composite material, can be widely used in economic crops such as tobacco, corn, peanut, soybean, traditional Chinese medicine, economic fruit tree, the afforestation of barren mountain area and flowers water saving, preserve moisture, protect fertilizer, can improve the quality and yield of economic crops, economic fruit tree and flowers.
Background technology China is a large agricultural country, and agricultural water accounts for about 70% of national total water amount, and wherein irrigation water accounts for more than 90% of agricultural water total amount, and up to 3600～3800 billion cubic meters, but availability is very low, only is 0.4～0.45.And the standard of developed country is 0.7, has a long way to go, and according to investigations, China's water resources ownership per capita is about 2220 cubic metres, only is 1/4 of world average level.The stem reality of shortage of water resources has become the great bottleneck of restriction Chinese national economy and social sustainable development.
Simultaneously, the technological reserve in the modern water-saving agriculture of China field is also very weak at present, lack the modern water-saving agriculture new technology that is fit to national conditions, thereby according to China's national situation, development is fit to the water-saving agriculture pattern of different regions characteristics with suiting measures to local conditions, foundation meets the water-saving agricultural technology system of national conditions, promote the sustainable development of water-saving agriculture, become the instant great strategic measure of China.
A kind of agricultural water-saving slow-releasing composite material of invention just for the conserve water resource, effectively utilizes water resource, improves the output and the quality of agricultural product, thereby improves the economic benefit of agricultural, has the important social benefit.
Super absorbent resin comes out in 20th century the mid-1970s, since its have water saving, energy-conservation, the raising crop yield important function, in recent years, in some developed countries, with the agricultural high-hygroscopicity resin is " the green earth plan " of major technique content, " administer the desert plan " and put into effect in succession, practical application effect is very remarkable.Just because of the specific function of this " resin ", more and more make it become people's research and one of concern front line science problem.
The development of domestic agricultural high-hygroscopicity resin is started late, through scientific research personnel's effort, aspect basic research and application study by certain progress.Main using method has directly spreads resin or utilizes packed waterishlogged resin to divide four jiaos to place into the soil.But, the cost height, use inconvenience, resin easily runs off, and it is low to inhale fertile multiplying power, and bad root phenomenon also takes place sometimes.Owing to have sodium element in the resin, in soil accumulation residual, influence the soil physics structure.
Summary of the invention is in order to overcome existing product cost height, to use inconvenience, and resin easily runs off, and it is low to inhale fertile multiplying power, and bad root phenomenon also takes place sometimes owing to have sodium element in the resin, in soil accumulation residual, influence the soil physics structure.The invention provides a kind of agricultural water-saving slow-releasing composite material, according to the mechanism of development of plants growth and rule design agricultural water-saving slow-releasing composite material structure and membrane material up and down, change or interpolation part material and raw material, be used for aspects such as economic crops, economic fruit tree, afforestation, flowers such as tobacco.Material can be degraded, and does not form new pollution source.
New solution proposed by the invention, nutrient solution and various special fertilizer and degradable material are combined with each other, make the water-saving slow-releasing composite material that is exclusively used in plant, slow-releasing composite material regulation and control soil water content, to the influence of economic plants (as tobacco, corn, trees etc.) physiological action, to improve business efficiency.Agricultural water-saving slow-releasing composite material by the lining, in, outer three layers form, up and down film be distributed be of moderate size, the aperture of spacing unanimity.Adventitia is thicker, and the ability of quite high prevention absorbing material degraded is not only arranged, and can also resist inhomogeneous light pressure, can be by pressure break when guaranteeing the agricultural water-saving slow-releasing composite material earthing.
The carrier of sandwich material has the effect of two aspects.Carry controlled macromolecule absorption material on the one hand, promote that on the other hand moisture spreads rapidly, guarantee good water storage capacity, be user-friendly to.
Whole agricultural water-saving slow-releasing composite material is formed a complete and independent relatively system, is loaded with " the little reservoir " of macromolecule absorption material on the sandwich material, absorbs water during washiness, slowly discharges moisture during arid and absorbs for root system.At Different Crop development growth rule, to the demand of different fertilizer element and susceptibility preparation dedicated fertilizer.Consider because a lot of regional soil potassium contents of China are not enough, take two kinds of ways to address this problem.The one, the sodium element in the resin is replaced with potassium element, make in the soil not any harmful substances such as residual sodium, adding potash fertilizer between the film up and down simultaneously, with the potash fertilizer that guarantees that plants such as tobacco need.
The invention has the beneficial effects as follows that agricultural water-saving slow-releasing composite material in use has water saving, preserves moisture, protects fertilizer, can improve the quality and yield of economic crops, economic fruit tree and flowers.Anti-light the pressure, material can be degraded, and does not form new pollution source.Be easy to storage and transportation, simultaneously low price
The embodiment agricultural water-saving slow-releasing composite material by the lining, in, outer three layers form, up and down film be distributed be of moderate size, the aperture of spacing unanimity.Adventitia is thicker, and the ability of quite high prevention absorbing material degraded is not only arranged, and can also resist inhomogeneous light pressure, can be by pressure break when guaranteeing the agricultural water-saving slow-releasing composite material earthing.
The carrier of sandwich material has the effect of two aspects.Carry controlled macromolecule absorption material on the one hand, promote that on the other hand moisture spreads rapidly, guarantee good water storage capacity, be user-friendly to.
Whole agricultural water-saving slow-releasing composite material is formed a complete and independent relatively system, is loaded with " the little reservoir " of macromolecule absorption material on the sandwich material, absorbs water during washiness, slowly discharges moisture during arid and absorbs for root system.
The interpolation of fertilizer element: at Different Crop development growth rule, to the demand of different fertilizer element and susceptibility preparation dedicated fertilizer.At present, consider, taked two kinds of ways to address this problem because a lot of regional soil potassium contents of China are not enough.The one, the sodium element in the resin is replaced with potassium element, make in the soil not any harmful substances such as residual sodium, adding potash fertilizer between the film up and down simultaneously, with the potash fertilizer that guarantees that plants such as tobacco need.
