Description
Technical field
The invention belongs to sand field of planting, be specifically related to the composite sand pattern of farming that a kind of utilization can be directly used in the water conservation of plantation, the porous of fertilizer conservation plants sand and nutrient planting sand and self-defence ventilative planting container.
Background technology
Desertization phenomenon is a kind of natural phenomena, is to cause some areas desertization because earth dry zone moves produced climatic variation.And along with the day by day severe of global climate and population increase fast, the soil brought excessively is developed and is cultivated, herding, causes global desertization process more and more faster, can plant arable land and day by day reduce, Agricultural production ability continuous decrease.Especially for such country of having a large population in a small area of China, growing desertization process cause agricultural and can planting soil minimizing and the negative effect brought is fatal.
Agricultural and can the minimizing day by day of planting soil, grain and crop yield is directly caused to decline, this is mainly due in current agriculture grain product and vegetables and fruits plant husbandry, main dependence be soil adhesion in and cohesion water conservation, fertilizer-preserving ability, the moisture and fertilizer that are applied to Plants are kept and plays effectiveness, the natural grains of sand after desertization then make it not have the ability of water conservation, fertilizer conservation because of surface is comparatively smooth and grains of sand adhesive capacity is each other poor, and cannot be used for the use of plantation.
At present, agronomists are for the improvement of desertization day by day, except being devoted to exploitation desert planting always, concentrating on and in desert, to carry out antiseepage or windproof process, weaken sandy soil migration, promote except the survival rate of desert, also be devoted to develop the plantation sand having water conservation, fertilizer conservation function that some can be applicable to daily agricultural planting, to expect that can improve agricultural soil reduces the predicament brought day by day on the one hand, also contributes to the utilization ratio improving the sand day by day gathered simultaneously.
Chinese patent CN102159667A discloses a kind of sand aggregate, described sand aggregate comprises by after organic waste or by product powder and edaphon mixing, and mix with sand and make edaphon be inoculated on sand, utilize the moisture of supply that edaphon is bred, utilize its mycelia that organic waste or by product powder and sand are condensed.When sand aggregate described in this invention supplies moisture to condense under the suitable state mixed the organic waste powder and sand that are mixed with edaphon, the phenomenon of sand with the wind can not only be prevented, can also nutrient be supplied, thus can steppification be carried out to sand ground or respectively be a farmer and trees at sandy cultivation.The organic waste powder be mixed in sand can play the effect of base manure and promote the growth of root system of plant, and the sand aggregate described in this patent also can additional fertilizer thus make sand ground continue fertilizer conservation in the plantation used time.
But for the process of sand in this invention, what adopt is general simple mixed processing, directly organic waste or by product powder and edaphon are mixed and be seeded on sand, the adhesion utilizing the cohesion of microorganism can realize between sand under having microorganism to exist, reduce the sandslide because Sand Movement causes, sand aggregate described in this invention is more be applied in desert planting to prevent the measure adopted of running off, and the performance of the preserve moisture and fertility that used time of daily plantation is needed, adhesion between microorganism then and inapplicable, and described sand without any pretreatment, can its smooth outer surface be applicable to microbial inoculant absorption and how adsorption capacity also remains to be discussed, therefore this sand aggregate be not suitable in daily plantation the use of the plantation taking sand as essentialspecies implant, therefore, significant limitation is still had for large-scale sand planting technology of promoting.

As can be seen from embodiment 1 and comparative example 1 and embodiment 5 and comparative example 2 data, when using identical existing porose planting container plantation, porous used in combination plantation sand of the present invention and nutrient planting sand facies are for existing soil plantation, the performance of its fertilizer conservation quite even increases, plant growth situation is also slightly good, prove that porous of the present invention plantation sand and nutrient planting sand have at least suitable with soil ability for plantation fertilizer conservation, be conducive to plant growth; As can be seen from the correction data in embodiment 2 and embodiment 3 and embodiment 5 and embodiment 6, using water-tight vessel as the use of plantation and fertilizer without loss time, the plant growth performance using the planting container of waterproof and breathable of the present invention to plant promotes more, fertilizer amount consumption simultaneously in container also exceeds a lot, visible permeability to the importance of plant growth, illustrate of the present invention there is good permeability planting container and described sand pattern of farming contribute to the growth of plant; From embodiment 2 and embodiment 4, and the data of embodiment 6 and embodiment 8 can be found out, the plant growth performance of the sand pattern of farming of laying with porous plantation layer of sand and the arrangement of nutrient planting layer of sand mode interlayer is better, and the utilization ratio of fertilizer is also higher.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
