Abstract
The invention relates to a special degradable water-retention film for orchards and a manufacturing method of the degradable water-retention film. The manufacturing method is characterized by including steps of firstly smashing kelps, adding 1-5% of alkaline matters to stir, stirring once each half an hour, treating for 1-2 hours, then filtering to collect filtrate, injecting the filtrate into 2-5% of calcium chloride water solution through a slit 1-1.5 meters in length and 3-5millimeters in width; and solidifying for 0.5-1 hour to obtain the degradable water-retention film. The degradable water-retention film is a hydrophilic jelly-shaped matter and has a water-retention function, water evaporation of the orchards is reduced, and water utilization efficiency is increased. Besides, the water-retention film can be degraded with the surrounding soil, soil organic matters are increased, and granule soil forming is promoted. The water-retention film has a remarkable soil improvement function, can utilize leftovers in kelp processing as raw materials and turn waste into wealth, and has evident environment-friendly effect.
Description
Technical field
The present invention relates to a kind of degradable membrane that reduces orchard water evaporates, raising buffering power of soil for the covering orchard soil and preparation method thereof, belong to fruit tree soil management technical field.
Background technology
For fear of " fruit grain strive ground ", China orchard often is based upon that soil layer is thinner, preserve moisture and fertility all relatively poor, lack the plot of irrigation conditions usually.Because northern China is more concentrated many local rainy seasons, only utilizes natural precipitation to be difficult to satisfy fruit tree growth to the demand of moisture, thereby preserve moisture and fertility is the important content of orchard soil management always.At present, water conservation measure in orchard mainly contains that fruit tree covers in the ranks that grass, plastic foil cover and orchard ground cover system etc.But often there are many shortcomings in these measures and are difficult to large-scale promotion application: as cover tsaoko garden easy ponding in summer, cause fruit tree root system vigor to descend, severe patient even root system rot; Plastic film covers the result cause and can not degrade and cause orchard soil pollution etc. owing to plastic film.Therefore, work out low cost, degradable orchard covering material for strengthening the orchard water management, satisfy the fruit tree water demand and have positive role.
Summary of the invention
At the problems referred to above, order of the present invention provides a kind of low cost, the special-purpose water-retaining film in degradable orchard, can reduce the orchard water evaporates, alleviates the contradiction of fruit tree water demand and orchard moisture supply, satisfies the fruit tree growth requirement.
The object of the invention is achieved through the following technical solutions: the characteristics of utilizing sodium alginate abundant in the sea-tangle and calcium chloride can form the calcium alginate colloid, the sodium alginate mixed liquor is injected calcium chloride solution by a slit, the film that forms ventilative, hydrophilic, degradable and have certain intensity.The present invention can also add the water retention that powerful water-keeping material improves film in the sodium alginate mixed liquor.
For reaching above-mentioned purpose, concrete technical scheme of the present invention is as follows:
At first sea-tangle is pulverized, add mass percent 1-5% alkaline matter and stir, stir 1 time processing time 1-2 hour every half an hour; Subsequent filtration is collected filtrate; Filtrate is passed through a slit (the long 1-1.5 rice of slit, wide 3-5 millimeter), in the implantation quality percentage 2-5% calcium chloride water; Solidify and to obtain the degradable water-retaining film in 0.5-1 hour.
Described alkaline matter is one or more in sodium carbonate, sodium bicarbonate, potash, the saleratus.
For strengthening water retention, in collected filtrate, can mix mass percent 1-2% water-loss reducer.
Described water-loss reducer is one or more in Sodium Polyacrylate, polyacrylamide or the sodium carboxymethylcellulose.
For strengthening the effect of soil beneficial microorganism, in collected filtrate, can mix mass percent 1-2% probiotic powder.
Described probiotic powder is the Mixed Microbes powder of ocean side spore bacillus brevis, bacillus subtilis, sphingol sporangium.
Advantage of the present invention is that calcium alginate film is a hydrophilic jelly, has significant water retention, has reduced the orchard soil water evaporates, improves water use efficiency.Prior calcium alginate film be easy to degraded and with surrounding soil melt for, improve the soil organic matter, promote the formation of soil aggregate to have significant soil improvement action.Thereby this film can water conservation, soil melioration and do not cause the plurality of advantages of any pollution.And can be with the holder of film as a basis, before solidifying, mix the slowly releases such as active substance of water-loss reducer, soil probio, weeds inhibitor or promotion root growth, improve the utilization ratio of these soil probios, weeds inhibitor and active substance, give film diversified function simultaneously.
The present invention can sea-tangle the offcuts of processing be raw material, can turn waste into wealth, have tangible environmental protection effect.
